Appendix A. Reference Material A.1. Server runtime arguments The application server startup script accepts arguments and switches at runtime. This allows the server to start under alternative configurations to those defined in the standalone.xml , domain.xml , and host.xml configuration files. Alternative configurations might include starting the server with an alternative socket bindings set or a secondary configuration. The available parameters list can be accessed by passing the help switch -h or --help at startup. Table A.1. Runtime Switches and Arguments Argument or Switch Operating Mode Description --admin-only Standalone Set the server's running type to ADMIN_ONLY . This will cause it to open administrative interfaces and accept management requests, but not start other runtime services or accept end user requests. Note that it is recommended to use --start-mode=admin-only instead. --admin-only Domain Set the host controller's running type to ADMIN_ONLY causing it to open administrative interfaces and accept management requests but not start servers or, if this host controller is the primary for the domain, accept incoming connections from secondary host controllers. -b=<value>, -b <value> Standalone, Domain Set system property jboss.bind.address , which is used in configuring the bind address for the public interface. This defaults to 127.0.0.1 if no value is specified. See the -b<interface>=<value> entry for setting the bind address for other interfaces. -b<interface>=<value> Standalone, Domain Set system property jboss.bind.address.<interface> to the given value. For example, -bmanagement= IP_ADDRESS --backup Domain Keep a copy of the persistent domain configuration even if this host is not the domain controller. -c=<config>, -c <config> Standalone Name of the server configuration file to use. The default is standalone.xml . -c=<config>, -c <config> Domain Name of the server configuration file to use. The default is domain.xml . --cached-dc Domain If the host is not the domain controller and cannot contact the domain controller at boot, boot using a locally cached copy of the domain configuration. --debug [<port>] Standalone Activate debug mode with an optional argument to specify the port. Only works if the launch script supports it. -D<name>[=<value>] Standalone, Domain Set a system property. --domain-config=<config> Domain Name of the server configuration file to use. The default is domain.xml . --git-repo Standalone The location of the Git repository that is used to manage and persist server configuration data. This can be local if you want to store it locally, or the URL to a remote repository. --git-branch Standalone The branch or tag name in the Git repository to use. This argument should name an existing branch or tag name as it will not be created if it does not exist. If you use a tag name, you put the repository in a detached HEAD state, meaning future commits are not attached to any branches. Tag names are read-only and are normally used when you need to replicate a configuration across several nodes. --git-auth Standalone The URL to an Elytron configuration file that contains the credentials to be used when connecting to a remote Git repository. This argument is required if your remote Git repository requires authentication. Elytron does not support SSH. Therefore, only default SSH authentication is supported using private keys without a password. This argument is not used with a local repository. -h, --help Standalone, Domain Display the help message and exit. --host-config=<config> Domain Name of the host configuration file to use. The default is host.xml . --interprocess-hc-address=<address> Domain Address on which the host controller should listen for communication from the process controller. --interprocess-hc-port=<port> Domain Port on which the host controller should listen for communication from the process controller. --primary-address=<address> Domain Set system property jboss.domain.primary.address to the given value. In a default secondary host controller configuration, this is used to configure the address of the primary host controller. --primary-port=<port> Domain Set system property jboss.domain.primary.port to the given value. In a default secondary host controller configuration, this is used to configure the port used for native management communication by the primary host controller. --read-only-server-config=<config> Standalone Name of the server configuration file to use. This differs from --server-config and -c in that the original file is never overwritten. --read-only-domain-config=<config> Domain Name of the domain configuration file to use. This differs from --domain-config and -c in that the initial file is never overwritten. --read-only-host-config=<config> Domain Name of the host configuration file to use. This differs from --host-config in that the initial file is never overwritten. -P=<url>, -P <url>, --properties=<url> Standalone, Domain Load system properties from the given URL. --pc-address=<address> Domain Address on which the process controller listens for communication from processes it controls. --pc-port=<port> Domain Port on which the process controller listens for communication from processes it controls. -S<name>[=<value>] Standalone Set a security property. -secmgr Standalone, Domain Runs the server with a security manager installed. --server-config=<config> Standalone Name of the server configuration file to use. The default is standalone.xml . --start-mode=<mode> Standalone Set the start mode of the server. This option cannot be used in conjunction with --admin-only . Valid values are: normal : The server will start normally. admin-only : The server will only open administrative interfaces and accept management requests but not start other runtime services or accept end user requests. suspend : The server will start in suspended mode and will not service requests until it has been resumed. -u=<value>, -u <value> Standalone, Domain Set system property jboss.default.multicast.address , which is used in configuring the multicast address in the socket-binding elements in the configuration files. This defaults to 230.0.0.4 if no value is specified. -v, -V, --version Standalone, Domain Display the application server version and exit. Warning The configuration files that ship with JBoss EAP are set up to handle the behavior of the switches, for example, -b and -u . If you change your configuration files to no longer use the system property controlled by the switch, then adding it to the launch command will have no effect. A.2. RPM service configuration files The RPM installation of JBoss EAP includes two additional configuration files compared to a ZIP or installer installation. These files are used by the service init script to specify the JBoss EAP launch environment. Important For Red Hat Enterprise Linux 7 and later, RPM service configuration files are loaded using systemd , so variable expressions are not expanded. Table A.2. RPM Configuration Files File Description /etc/opt/rh/eap8/wildfly/eap8-standalone.conf Settings specific to standalone JBoss EAP servers on Red Hat Enterprise Linux 8 and later. /etc/opt/rh/eap8/wildfly/eap8-domain.conf Settings specific to JBoss EAP running as a managed domain on Red Hat Enterprise Linux 8 and later. A.3. RPM service configuration properties The following table shows a list of available configuration properties for the JBoss EAP RPM service along with their default values. Note If a property has the same name in both the RPM service configuration file, such as /usr/lib/systemd/system/eap8-standalone.service: , and in the JBoss EAP startup configuration file, such as EAP_HOME /bin/standalone.conf , the value that takes precedence is the one in the JBoss EAP startup configuration file. One such property is JAVA_HOME . Table A.3. RPM Service Configuration Properties Property Description JAVA_HOME The directory where your Java Runtime Environment is installed. Default value: /usr/lib/jvm/jre JAVAPTH The path where the Java executable files are installed. Default value: USDJAVA_HOME/bin WILDFLY_CONSOLE_LOG The file that the CONSOLE log handler will be redirected to. Default value: /var/opt/rh/eap8/log/wildfly/standalone/console.log for a standalone server, or /var/opt/rh/eap8/log/wildfly/domain/console.log for a managed domain. WILDFLY_SH The script used to launch the JBoss EAP server. Default value: /opt/rh/eap8/root/usr/share/wildfly/bin/standalone.sh for a standalone server, or /opt/rh/eap8/root/usr/share/wildfly/bin/domain.sh for a managed domain. WILDFLY_SERVER_CONFIG The server configuration file to use. There is no default for this property. Either standalone.xml or domain.xml can be specified at start. WILDFLY_HOST_CONFIG For a managed domain, this property allows a user to specify the host configuration file, such as host.xml . It has no value set as the default. WILDFLY_MODULEPATH The path of the JBoss EAP module directory. Default value: /opt/rh/eap8/root/usr/share/wildfly/modules WILDFLY_BIND Sets the jboss.bind.address system property, which is used to configure the bind address for the public interface. This defaults to 0.0.0.0 if no value is specified. WILDFLY_OPTS Additional arguments to include on startup. For example: A.4.

A.6. Management audit logging attributes Note Attribute names in these tables are listed as they appear in the management model, for example, when using the management CLI. See the schema definition file located at EAP_HOME /docs/schema/wildfly-config_5_0.xsd to view the elements as they appear in the XML, as there may be differences from the management model. Table A.6. Management audit logging: Logger attributes Attribute Description enabled Whether audit logging is enabled. log-boot Whether operations should be logged on server boot. log-read-only Whether operations that do not modify the configuration or any runtime services should be logged. Table A.7. Management audit logging: Log formatter attributes Attribute Description compact If true , it will format the JSON on one line. There may still be values containing new lines, so if having the whole record on one line is important, set escape-new-line or escape-control-characters to true . date-format The date format to use as understood by java.text.SimpleDateFormat . This is ignored if include-date is set to false . date-separator The separator between the date and the rest of the formatted log message. This is ignored if include-date is set to false . escape-control-characters If true , it will escape all control characters, ASCII entries with a decimal value greater than 32 , with the ASCII code in octal. For example, a new line becomes #012 . If true , this will override escape-new-line=false . escape-new-line If true , it will escape all new lines with the ASCII code in octal: #012 . include-date Whether or not to include the date in the formatted log record. Table A.8. Management audit logging: File handler attributes Attribute Description disabled-due-to-failure Whether this handler has been disabled due to logging failures (read-only). failure-count The number of logging failures since the handler was initialized (read-only). formatter The JSON formatter used to format the log messages. max-failure-count The maximum number of logging failures before disabling this handler. path The path of the audit log file. relative-to The name of another previously named path, or of one of the standard paths provided by the system.

If undefined, it will default to 1024 bytes if the syslog-format is RFC3164 , or 2048 bytes if the syslog-format is RFC5424 . protocol The protocol to use for the syslog handler. Must be one and only one of udp , tcp or tls . syslog-format The syslog format: RFC5424 or RFC3164 . truncate Whether or not a message, including the header, should truncate the message if the length in bytes is greater than the value of the max-length attribute. If set to false , messages will be split and sent with the same header values. Note Syslog servers vary in their implementation, so not all settings are applicable to all syslog servers. Testing has been conducted using the rsyslog syslog implementation. This table lists only the high-level attributes. Each attribute has configuration parameters, and some have child configuration parameters. A.7. Interface attributes Note Attribute names in this table are listed as they appear in the management model, for example, when using the management CLI. See the schema definition file located at EAP_HOME /docs/schema/wildfly-config_5_0.xsd to view the elements as they appear in the XML, as there may be differences from the management model. Table A.10. Interface attributes and values Interface element Description any Element indicating that part of the selection criteria for an interface should be that it meets at least one, but not necessarily all, of the nested set of criteria. any-address Empty element indicating that sockets using this interface should be bound to a wildcard address. The IPv6 wildcard address ( :: ) will be used unless the java.net.preferIPv4Stack system property is set to true, in which case the IPv4 wildcard address ( 0.0.0.0 ) will be used. If a socket is bound to an IPv6 anylocal address on a dual-stack machine, it can accept both IPv6 and IPv4 traffic; if it is bound to an IPv4 (IPv4-mapped) anylocal address, it can only accept IPv4 traffic. inet-address Either an IP address in IPv6 or IPv4 dotted decimal notation, or a host name that can be resolved to an IP address. link-local-address Empty element indicating that part of the selection criteria for an interface should be whether or not an address associated with it is link-local. loopback Empty element indicating that part of the selection criteria for an interface should be whether or not it is a loopback interface. loopback-address A loopback address that may not actually be configured on the machine's loopback interface. Differs from inet-address type in that the given value will be used even if no NIC can be found that has the IP address associated with it. multicast Empty element indicating that part of the selection criteria for an interface should be whether or not it supports multicast. name The name of the interface. nic The name of a network interface (e.g. eth0, eth1, lo). nic-match A regular expression against which the names of the network interfaces available on the machine can be matched to find an acceptable interface. not Element indicating that part of the selection criteria for an interface should be that it does not meet any of the nested set of criteria. point-to-point Empty element indicating that part of the selection criteria for an interface should be whether or not it is a point-to-point interface. public-address Empty element indicating that part of the selection criteria for an interface should be whether or not it has a publicly routable address. site-local-address Empty element indicating that part of the selection criteria for an interface should be whether or not an address associated with it is site-local. subnet-match A network IP address and the number of bits in the address' network prefix, written in slash notation , for example, 192.168.0.0/16 . up Empty element indicating that part of the selection criteria for an interface should be whether or not it is currently up. virtual Empty element indicating that part of the selection criteria for an interface should be whether or not it is a virtual interface. A.8. Socket binding attributes Note Attribute names in these tables are listed as they appear in the management model, for example, when using the management CLI. See the schema definition file located at EAP_HOME /docs/schema/wildfly-config_5_0.xsd to view the elements as they appear in the XML, as there may be differences from the management model. The following tables show the attributes that can be configured for each of the three types of socket bindings. socket-binding remote-destination-outbound-socket-binding local-destination-outbound-socket-binding Table A.11. Inbound Socket Binding (socket-binding) Attributes Attribute Description client-mappings Specifies the client mappings for this socket binding. A client connecting to this socket should use the destination address specified in the mapping that matches its desired outbound interface. This allows for advanced network topologies that use either network address translation, or have bindings on multiple network interfaces to function. Each mapping should be evaluated in declared order, with the first successful match used to determine the destination. fixed-port Whether the port value should remain fixed even if numeric offsets are applied to the other sockets in the socket group. interface Name of the interface to which the socket should be bound, or, for multicast sockets, the interface on which it should listen. This should be one of the declared interfaces. If not defined, the value of the default-interface attribute from the enclosing socket binding group will be used. multicast-address Multicast address on which the socket should receive multicast traffic. If unspecified, the socket will not be configured to receive multicast. multicast-port Port on which the socket should receive multicast traffic. Must be configured if multicast-address is configured. name The name of the socket. Services needing to access the socket configuration information will find it using this name. This attribute is required. port Number of the port to which the socket should be bound. Note that this value can be overridden if servers apply a port-offset to increment or decrement all port values. Table A.12. Remote Outbound Socket Binding (remote-destination-outbound-socket-binding) Attributes Attribute Description fixed-source-port Whether the port value should remain fixed even if numeric offsets are applied to the other outbound sockets in the socket group. host The host name or IP address of the remote destination to which this outbound socket will connect. port The port number of the remote destination to which the outbound socket should connect. source-interface The name of the interface that will be used for the source address of the outbound socket. source-port The port number that will be used as the source port of the outbound socket. Table A.13. Local Outbound Socket Binding (local-destination-outbound-socket-binding) Attributes Attribute Description fixed-source-port Whether the port value should remain fixed even if numeric offsets are applied to the other outbound sockets in the socket group. socket-binding-ref The name of the local socket binding that will be used to determine the port to which this outbound socket connects. source-interface The name of the interface that will be used for the source address of the outbound socket. source-port The port number that will be used as the source port of the outbound socket.

Module command arguments Argument Description --absolute-resources Use this argument to specify a list of absolute file system paths to reference from its module.xml file. The files specified are not copied to the module directory. See --resource-delimiter for delimiter details. --allow-nonexistent-resources Use this argument to create empty directories for resources specified by --resources that do not exist. The module add command will fail if there are resources that do not exist and this argument is not used. --dependencies Use this argument to provide a comma-separated list of module names that this module depends on. --export-dependencies Use this argument to specify exported dependencies. Note The MySQL driver JAR name, mysql-connector-j-8.0.33.jar, is provided only as an example. For information about the tested MySQL version, see Tested databases . --main-class Use this argument to specify the fully qualified class name that declares the module's main method. --module-root-dir Use this argument if you have defined an external JBoss EAP module directory to use instead of the default EAP_HOME /modules/ directory. Note The MySQL driver JAR name, mysql-connector-j-8.0.33.jar, is provided only as an example. For information about the tested MySQL version, see Tested databases . --module-xml Use this argument to provide a file system path to a module.xml to use for this new module. This file is copied to the module directory. If this argument is not specified, a module.xml file is generated in the module directory. --name Use this argument to provide the name of the module to add. This argument is required. --properties Use this argument to provide a comma-separated list of PROPERTY_NAME = PROPERTY_VALUE pairs that define module properties. --resource-delimiter Use this argument to set a user-defined file path separator for the list of resources provided to the --resources or absolute-resources argument. If not set, the file path separator is a colon ( : ) for Linux and a semicolon ( ; ) for Windows. --resources Use this argument to specify the resources for this module by providing a list of file system paths. The files are copied to this module directory and referenced from its module.xml file. If you a provide a path to a directory, the directory and its contents are copied to the module directory. Symbolic links are not preserved; linked resources are copied to the module directory. This argument is required unless --absolute-resources or --module-xml is provided. See --resource-delimiter for delimiter details. --slot Use this argument to add the module to a slot other than the default main slot. Note The MySQL driver JAR name, mysql-connector-j-8.0.33.jar, is provided only as an example. For information about the tested MySQL version, see Tested databases . A.11. Deployment scanner marker files Marker files are used by the deployment scanner to mark the status of an application within the deployment directory of the JBoss EAP server instance. A marker file has the same name as the deployment, with the file suffix indicating the state of the application's deployment. For example, a successful deployment of test-application.war would have a marker file named test-application.war.deployed . The following table lists the available marker file types and their meanings. Table A.20. Marker File Types Filename Suffix Origin Description .deployed System-generated Indicates that the content has been deployed. The content will be undeployed if this file is deleted. .dodeploy User-generated Indicates that the content should be deployed or redeployed. .failed System-generated Indicates deployment failure. The marker file contains information about the cause of failure. If the marker file is deleted, the content will be eligible for auto-deployment again. .isdeploying System-generated Indicates that the deployment is in progress. This marker file will be deleted upon completion. .isundeploying System-generated Triggered by deleting a .deployed file, this indicates that the content is being undeployed. This marker file will be deleted upon completion. .pending System-generated Indicates that the deployment scanner recognizes the need to deploy content, but an issue is currently preventing auto-deployment (for example, if content is in the process of being copied). This marker serves as a global deployment road-block, meaning that the scanner will not instruct the server to deploy or undeploy any content while this marker file exists. .skipdeploy User-generated Disables auto-deploy of an application while present. Useful as a method of temporarily blocking the auto-deployment of exploded content, preventing the risk of incomplete content edits being pushed. Can be used with zipped content, although the scanner detects in-progress changes to zipped content and waits until completion. .undeployed System-generated Indicates that the content has been undeployed.

This controls the maximum amount of memory that can be used for caching. Byte Buffer Pool Attributes Table A.52. byte-buffer-pool Attributes Attribute Default Description buffer-size The size, in bytes, of each buffer slice. If not specified, the size is set based on the available RAM of your system: 512 bytes for less than 64 MB RAM 1024 bytes (1 KB) for 64 MB - 128 MB RAM 16384 bytes (16 KB) for more than 128 MB RAM For performance tuning advice on this attribute, see Configuring Buffer Pools in the JBoss EAP Performance tuning for JBoss EAP . direct Boolean value that denotes if this buffer is a direct or heap pool. If not specified, the value is set based on the available RAM of your system: If available RAM is < 64MB, the value is set to false If available RAM is >= 64MB, the value is set to true Note that direct pools also have a corresponding heap pool. leak-detection-percent 0 The percentage of buffers that should be allocated with a leak detector. max-pool-size The maximum number of buffers to keep in the pool. Buffers will still be allocated above this limit, but will not be retained if the pool is full. thread-local-cache-size 12 The size of the per-thread cache.

Generic Protocol Attributes All of the protocols have access to the following attributes. Table A.110. protocol Attributes Attribute Default Description module org.jgroups The module with which to resolve the protocol type. properties Properties of this protocol. statistics-enabled false Whether statistics are enabled. Authentication Protocols The authentication protocols are used to perform authentication, and are primarily responsible for ensuring that only authenticated members can join the cluster. These protocols sit below the GMS protocol, so that they may listen for requests to join the cluster. AUTH SASL AUTH Attributes While the AUTH protocol contains no additional attributes, it must have a token defined as a child element. Note When defining this protocol, the auth-protocol element is used instead of the protocol element. Token Types When using Elytron for security, it is recommended to use one of the following authentication tokens. These authentication tokens were intentionally designed for use with Elytron, and may not be used with legacy security configurations. Table A.111. Elytron Token Types Token Description cipher-token An authentication token where the shared secret is transformed. RSA is the default algorithm used for the transformation. digest-token An authentication token where the shared secret is transformed. SHA-256 is the default algorithm used for the transformation. plain-token An authentication token with no additional transformations to the shared secret. The following authentication tokens are inherited from JGroups, and are eligible for use in any configuration where authentication is desired. Table A.112. JGroups Token Types Token Description MD5Token An authentication token where the shared secret is encrypted using either an MD5 or SHA hash. MD5 is the default algorithm used for the encryption. SimpleToken An authentication token with no additional transformations to the shared secret. This token is case-insensitive, and case is not considered when determining if strings match. X509Token An authentication token where the shared secret is encrypted using an X509 certificate. SASL Attributes Table A.113. SASL Attributes Attribute Default Description client_callback_handler The class name of the CallbackHandler to use when a node acts as a client. client_name The name to use when a node acts as a client. This name will also be used to obtain the subject if using a JAAS login module. client_password The password to use when a node acts as a client. This password will also be used to obtain the subject if using a JAAS login module. login_module_name The name of the JAAS login module to use as a subject for creating the SASL client and server. This attribute is only required by certain mech values, such as GSSAPI. mech The name of the SASL authentication mechanism. This name can be any mechanism supported by the local SASL provider, and the JDK supplies CRAM-MD5 , DIGEST-MD5 , GSSAPI , and NTLM by default. sasl_props Properties of the defined mech . server_callback_handler The class name of the CallbackHandler to use when a node acts as a server. server_name The fully qualified server name. timeout 5000 The number of milliseconds to wait for a response to a challenge. Discovery Protocols The following protocols are used to find an initial membership for the cluster, which can then be used to determine the current coordinator. A list of the discovery protocols are below. AZURE_PING JDBC_PING MPING PING S3_PING TCPGOSSIP TCPPING AZURE_PING Attributes Table A.114. AZURE_PING Attributes Attribute Default Description container The name of the blob container to use for PING data.

SYM_ENCRYPT Attributes Attribute Default Description key-alias The alias of the encryption key from the specified keystore. key-credential-reference The credentials required to obtain the encryption key from the keystore. key-store A reference to a keystore containing the encryption key. Failure Detection Protocols The following protocols are used to probe members of the cluster to determine if they are still alive. These protocols do not have any additional attributes beyond the generic attributes. FD_ALL FD_SOCK VERIFY_SUSPECT Flow Control Protocols The following protocols are responsible for flow control, or the process of adjusting the rate of a message sender to the slowest receiver. If a sender continuously sends messages at a rate faster than the receiver, then the receivers will either queue up or discard messages, resulting in retransmissions. These protocols do not have any additional attributes beyond the generic attributes. MFC - Multicast Flow Control UFC - Unicast Flow Control Group Membership Protocols The pbcast.GMS protocol is responsible for new members joining the cluster, existing members leaving the cluster, and members that are suspected of having crashed. This protocol does not have any additional attributes beyond the generic attributes. Merge Protocols If the cluster becomes split, then the MERGE3 protocol is responsible for merging the subclusters back together. While this protocol is responsible for merging the cluster members back together, this will not merge the state of the cluster. The application is responsible for handling the callback to merge states. This protocol does not have any additional attributes beyond the generic attributes. Message Stability The pbcast.STABLE protocol is responsible for garbage collecting messages that have been seen by all members of the cluster. This protocol initiates a stable message containing message numbers for a given member, called a digest. Once all members of the cluster have received the others' digests, then the message may be removed from the retransmission table. This protocol does not have any additional attributes beyond the generic attributes. Reliable Message Transmission The following protocols provide reliable message delivery and FIFO properties for messages sent to all nodes in a cluster. Reliable delivery means that no messages sent by a sender will ever be lost, as all messages are numbered, and retransmission requests are sent if a sequence number is not received. These protocols do not have any additional attributes beyond the generic attributes. pbcast.NAKACK2 pbcast.UNICAST3 Deprecated Protocols The following protocols have been deprecated, and have been replaced by a protocol that contains only the class name. For instance, instead of specifying org.jgroups.protocols.ASYM_ENCRYPT , the protocol name would be ASYM_ENCRYPT . org.jgroups.protocols.ASYM_ENCRYPT org.jgroups.protocols.AUTH org.jgroups.protocols.JDBC_PING org.jgroups.protocols.SYM_ENCRYPT org.jgroups.protocols.TCPGOSSIP org.jgroups.protocols.TCPPING A.34. Apache HTTP Server mod_cluster Directives The mod_cluster connector is an Apache HTTP Server-based load balancer. It uses a communication channel to forward requests from the Apache HTTP Server to one of a set of application server nodes. The following directives can be set to configure mod_cluster. Note There is no need to use ProxyPass directives because mod_cluster automatically configures the URLs that must be forwarded to Apache HTTP Server. Table A.121. mod_cluster Directives Directive Description Values CreateBalancers Defines how the balancers are created in the Apache HTTP Server VirtualHosts. This allows directives like: ProxyPass /balancer://mycluster1/ . 0 : Create all VirtualHosts defined in Apache HTTP Server 1 : Do not create balancers (at least one ProxyPass or ProxyMatch is required to define the balancer names) 2 : Create only the main server (default) UseAlias Check that the alias corresponds to the server name. 0 : Ignore aliases (default) 1 : Check aliases LBstatusRecalTime Time interval in seconds for load-balancing logic to recalculate the status of a node. Default: 5 seconds WaitBeforeRemove Time in seconds before a removed node is forgotten by httpd. Default: 10 seconds ProxyPassMatch/ProxyPass ProxyPassMatch and ProxyPass are mod_proxy directives which, when using ! instead of the back-end URL, prevent reverse-proxy in the path. This is used to allow Apache HTTP Server to serve static content. For example: ProxyPassMatch ^(/.*\.gif)USD ! This example allows the Apache HTTP Server to serve the .gif files directly. Note Due to performance optimizations for sessions in JBoss EAP 8.0, configuring hot-standby nodes is not supported. mod_manager The context of a mod_manager directive is VirtualHost in all cases, except when mentioned otherwise. server config context implies that the directive must be outside a VirtualHost configuration. If not, an error message is displayed and the Apache HTTP Server does not start. Table A.122. mod_manager Directives Directive Description Values EnableMCPMReceive Allow the VirtualHost to receive the MCPM from the nodes. Include EnableMCPMReceive in the Apache HTTP Server configuration to allow mod_cluster to work. Save it in the VirtualHost where you configure advertising. MemManagerFile The base name for the names that mod_manager uses to store configuration, generate keys for shared memory or locked files. This must be an absolute path name; the directories are created if needed. It is recommended that these files are placed on a local drive and not an NFS share. Context: server config USDserver_root/logs/ Maxcontext The maximum number of contexts supported by mod_cluster. Context: server config Default: 100 Maxnode The maximum number of nodes supported by mod_cluster. Context: server config Default: 20 Maxhost The maximum number of hosts, or aliases, supported by mod_cluster. It also includes the maximum number of balancers. Context: server config Default: 20 Maxsessionid The number of active sessionid stored to provide the number of active sessions in the mod_cluster-manager handler. A session is inactive when mod_cluster does not receive any information from the session within 5 minutes. Context: server config. This field is for demonstration and debugging purposes only. 0 : the logic is not activated. MaxMCMPMaxMessSize The maximum size of MCMP messages from other Max directives Calculated from other Max directives. Min: 1024 ManagerBalancerName The name of balancer to use when the JBoss EAP instance does not provide a balancer name. mycluster PersistSlots Tells mod_slotmem to persist nodes, aliases and contexts in files. Context: server config Off CheckNonce Switch check of nonce when using mod_cluster-manager handler. on/off Default: on - Nonce checked AllowDisplay Switch additional display on mod_cluster-manager main page. on/off Default: off - only version is displayed AllowCmd Allow commands using mod_cluster-manager URL. on/off Default: on - Commands allowed ReduceDisplay Reduce the information displayed on the main mod_cluster-manager page, so that more nodes can be displayed on the page. on/off Default: off - full information is displayed SetHandler mod_cluster-manager Displays information about the node that mod_cluster sees from the cluster. The information includes generic information and additionally counts the number of active sessions. <Location /mod_cluster-manager> SetHandler mod_cluster-manager Require ip 127.0.0.1 </Location> on/off Default: off Note When accessing the location defined in httpd.conf : Transferred: Corresponds to the POST data sent to the back-end server. Connected: Corresponds to the number of requests that have been processed when the mod_cluster status page was requested. Num_sessions: Corresponds to the number of sessions mod_cluster report as active (on which there was a request within the past 5 minutes). This field is not present when Maxsessionid is zero and is for demonstration and debugging purposes only. A.35. ModCluster Subsystem Attributes The modcluster subsystem has the following structure: proxy load-provider=dynamic custom-load-metric load-metric load-provider=simple ssl The load-provider=dynamic resource allows you to configure factors, such as CPU, sessions, heap, memory, and weight to determine the load balancing behavior. The load-provider=simple resource allows setting only a static constant as the factor attribute. This helps when the user does not need dynamic or complex rules to load balance the incoming HTTP requests. Note Attribute names in these tables are listed as they appear in the management model, for example, when using the management CLI. See the schema definition file located at EAP_HOME /docs/schema/jboss-as-mod-cluster_3_0.xsd to view the elements as they appear in the XML, as there may be differences from the management model. Table A.123. proxy Configuration Options Attribute Default Description advertise true Whether to enable multicast-based advertise mechanism. advertise-security-key It is a shared secret between an httpd instance and the JBoss EAP servers listening for advertisements from the httpd instance. advertise-socket The name of the balancer on the reverse proxy to register with. auto-enable-contexts true If set to false , contexts are registered with the reverse proxy as disabled. You can enable the context using the enable-context operation or by using the mod_cluster_manager console. balancer The name of the balancer on the reverse proxy to register with. If not set, the value is configured on the Apache HTTP Server side with the ManagerBalancerName directive, which defaults to mycluster . connector The name of Undertow listener that mod_cluster reverse proxy will connect to. excluded-contexts A list of contexts to exclude from registration with the reverse proxies. If no host is indicated, the host is assumed to be localhost . ROOT indicates the root context of the web application. flush-packets false Whether or not to enable packet flushing to the web server. flush-wait -1 Time to wait before flushing packets in httpd. Max value is 2,147,483,647 . listener The name of the Undertow listener that will be registered with the reverse proxy. load-balancing-group If set, requests are sent to the specified load balancing group on the load balancer. max-attempts 1 The number of times the reverse proxy will attempt to send a given request to a worker before giving up. node-timeout -1 Timeout, in seconds, for proxy connections to a worker. This is the time that mod_cluster will wait for the back-end response before returning an error. If the node-timeout attribute is undefined, the httpd ProxyTimeout directive is used. If ProxyTimeout is undefined, the httpd Timeout directive is used, which defaults to 300 seconds. ping 10 Time, in seconds, in which to wait for a pong answer to a ping. proxies List of proxies for mod_cluster to register with defined by outbound-socket-binding in socket-binding-group . proxy-list List of proxies. The format is HOST_NAME : PORT , separated with commas. Deprecated in favor of proxies . proxy-url / Base URL for MCMP requests. session-draining-strategy DEFAULT Session draining strategy used during undeployment of a web application. Valid values are DEFAULT , ALWAYS , or NEVER . DEFAULT Drain sessions before web application undeploy only if the web application is non-distributable. ALWAYS Always drain sessions before web application undeploy, even for distributable web applications. NEVER Do not drain sessions before web application undeploy. load-provider=simple A load provider to use if no dynamic load provider is present. It assigns each cluster member a load factor of 1 , and distributes work evenly without applying a load balancing algorithm. smax -1 Soft maximum idle connection count in httpd. socket-timeout 20 Number of seconds to wait for a response from an httpd proxy to MCMP commands before timing out, and flagging the proxy as in error. ssl-context Reference to the SSLContext to be used by mod_cluster. status-interval 10 Number of seconds a STATUS message is sent from the application server to the reverse proxy. Allowed values are between 1 and 2,147,483,647 . sticky-session true Whether subsequent requests for a given session should be routed to the same node, if possible. sticky-session-force false Whether the reverse proxy should return an error in the event that the balancer is unable to route a request to the node to which it is stuck. This setting is ignored if sticky sessions are disabled. sticky-session-remove false Remove session information on failover. stop-context-timeout 10 The maximum time, in seconds, to wait for a context to process pending requests, for a distributable context, or to destroy active sessions, for a non-distributable context. ttl -1 Time to live, in seconds, for idle connections above smax. Allowed values are between -1 and 2,147,483,647 . worker-timeout -1 Timeout to wait in httpd for an available worker to process the requests. Allowed values are between -1 and 2,147,483,647 . Table A.124. load-provider=dynamic Configuration Options Attribute Default Description decay 2 The decay. history 9 The history. initial-load 0 The initial load reported by a node. The valid range is 0-100 , with 0 indicating maximum load. This attribute helps to gradually increase the load value of a newly joined node to avoid overloading it while joining a cluster. You can disable this behavior by setting the value as -1 . When disabled, the node will report a load value of 100 , indicating that it has no load when joining a cluster. Table A.125. custom-load-metric Attribute Options Attribute Default Description capacity 1.0 The capacity of the metric. class The class name of the custom metric. property The properties for the metric. weight 1 The weight of the metric. Table A.126. load-metric Attribute Options Attribute Default Description capacity 1.0 The capacity of the metric. property The properties for the metric. type The type of the metric. Valid values are cpu , mem , heap , sessions , receive-traffic , send-traffic , requests , or busyness . weight 1 The weight of the metric. Table A.127. ssl Attribute Options Attribute Default Description ca-certificate-file Certificate authority. ca-revocation-url Certificate authority revocation list. certificate-key-file USD{user.home}/.keystore Key file for the certificate. cipher-suite The allowed cipher suite. key-alias The key alias. password changeit Password. protocol TLS The SSL protocols that are enabled. A.36. mod_jk Worker Properties The workers.properties file defines the behavior of the workers to which mod_jk passes client requests. The workers.properties file defines where the different application servers are located and the way the workload should be balanced across them. The general structure of a property is worker. WORKER_NAME . DIRECTIVE . The WORKER_NAME is a unique name that must match the instance-id configured in the JBoss EAP undertow subsystem . The DIRECTIVE is the setting to be applied to the worker. Configuration Reference for Apache mod_jk Load Balancers Templates specify default per-load-balancer settings. You can override the template within the load-balancer settings itself. Table A.128. Global properties Property Description worker.list A comma separated list of worker names that will be used by mod_jk . Table A.129. Mandatory Directives Property Description type The type of worker. The default type is ajp13 . Other possible values are ajp14 , lb , status . For more information on these directives, see the Apache Tomcat Connectors Reference at https://tomcat.apache.org/connectors-doc/reference/workers.html . Table A.130. Load Balancing Directives Property Description balance_workers Specifies the worker nodes that the load balancer must manage. You can use the directive multiple times for the same load balancer. It consists of a comma-separated list of worker node names. sticky_session Specifies whether requests from the same session are always routed to the same worker. The default is 1 , meaning that sticky sessions are enabled. To disable sticky sessions, set it to 0 . Sticky sessions should usually be enabled, unless all of your requests are truly stateless. Table A.131. Connection Directives Property Description host The host name or IP address of the back-end server. The back-end server must support the ajp protocol stack. The default value is localhost . port The port number of the back-end server instance listening for defined protocol requests. The default value is 8009 , which is the default listening port for AJP13 workers. The default value for AJP14 workers is 8011 . ping_mode The conditions under which connections are probed for network status. The probe uses an empty AJP13 packet for CPing, and expects a CPong in response. Specify the conditions by using a combination of directive flags. The flags are not separated by a comma or any white-space. The ping_mode can be any combination of C, P, I, and A. C - Connect. Probe the connection one time after connecting to the server. Specify the timeout using the value of connect_timeout. Otherwise, the value of ping_timeout is used. P - Prepost. Probe the connection before sending each request to the server. Specify the timeout using the prepost_timeout directive. Otherwise, the value of ping_timeout is used. I - Interval. Probe the connection at an interval specified by connection_ping_interval, if present. Otherwise, the value of ping_timeout is used. A - All. A shortcut for CPI, which specifies that all connection probes are used. ping_timeout, connect_timeout, prepost_timeout, connection_ping_interval The timeout values for the connection probe settings above. The value is specified in milliseconds, and the default value for ping_timeout is 10000 . lbfactor Specifies the load-balancing factor for an individual back-end server instance. This is useful to give a more powerful server more of the workload. To give a worker 3 times the default load, set this to 3 : worker.my_worker.lbfactor=3 The example below demonstrates load balancing with sticky sessions between two worker nodes, node1 and node2 , listening on port 8009 . Example: workers.properties File Further configuration details for Apache mod_jk are out of the scope of this document and can be found in the Apache documentation . A.37. Security Manager Subsystem Attributes The security-manager subsystem itself does not have configurable attributes, but it has one child resource with configurable attributes: deployment-permissions=default . Note Attribute names in this table are listed as they appear in the management model, for example, when using the management CLI. See the schema definition file located at EAP_HOME /docs/schema/wildfly-security-manager_1_0.xsd to view the elements as they appear in the XML, as there may be differences from the management model. Table A.132. deployment-permissions Configuration Options Attribute Description maximum-permissions The maximum set of permissions that can be granted to a deployment or JARs. minimum-permissions The minimum set of permissions to be granted to a deployment or JARs. A.38. Install OpenSSL from JBoss Core Services The JBoss Core Services OpenSSL files can be installed either from the ZIP or from the RPM distributions. Follow the below steps depending on your installation method of choice. Note On Red Hat Enterprise Linux 8, standard system OpenSSL is supported thus installation of OpenSSL from JBoss Core Services is not necessary anymore. Using JBoss Core Services OpenSSL ZIP File Distribution Note The path to libs/ directory in the ZIP archive is jbcs-openssl- VERSION /openssl/lib(64) for Linux and jbcs-openssl- VERSION /openssl/bin for Windows. Download the OpenSSL package from the Software Downloads page that pertains to your operating system and architecture. Extract the downloaded ZIP file to your installation directory. Notify JBoss EAP where to find the OpenSSL libaries. You can do this using either of the following methods. In each of the following commands, be sure to replace JBCS_OPENSSL_PATH with the path to the JBoss Core Services OpenSSL libraries, for example, /opt/rh/jbcs-httpd24/root/usr/lib64 . You can add the OpenSSL path to the JAVA_OPTS variable in the standalone.conf or domain.conf configuration file using the following argument. You can define a system property that specifies the OpenSSL path using the following management CLI command. Important Regardless of the method you use, you must perform a server restart for either the JAVA_OPTS value or the system property to take effect. A server reload is not sufficient. Using JBoss Core Services OpenSSL RPM Distribution Ensure that the system is registered to the JBoss Core Services channel: Determine the JBoss Core Services CDN repository name for your operating system version and architecture: RHEL 6 : jb-coreservices-1-for-rhel-6-server-rpms RHEL 7 : jb-coreservices-1-for-rhel-7-server-rpms Enable the repository on the system: Ensure the following message is seen: Install OpenSSL from this channel: Once the installation completes, the JBCS OpenSSL libraries will be available in /opt/rh/jbcs-httpd24/root/usr/lib64 , or just /opt/rh/jbcs-httpd24/root/usr/lib on x86 architecture. Notify JBoss EAP where to find the OpenSSL libaries. You can do this using either of the following methods. In each of the following commands, be sure to replace JBCS_OPENSSL_PATH with the path to the JBoss Core Services OpenSSL libraries, for example, /opt/rh/jbcs-httpd24/root/usr/lib64 . You can update the WILDFLY_OPTS variable for the eap7-standalone or eap7-domain settings in the service configuration file. You can define a system property that specifies the OpenSSL path using the following management CLI command. Important Regardless of the method you use, you must perform a server restart for either the WILDFLY_OPTS value or the system property to take effect. A server reload is not sufficient. A.39. Configure JBoss EAP to use OpenSSL There are multiple ways in which you can configure JBoss EAP to use OpenSSL: You can reconfigure the elytron subsystem to give OpenSSL priority so that it is used in all cases by default. Note Although OpenSSL is installed in the elytron subsystem, it is not the default TLS provider. In the elytron subsystem, the OpenSSL provider can also be specified on the ssl-context resource. That way, the OpenSSL protocol can be selected on a case-by-case basis instead of using the default priority. To create the ssl-context resource and use the OpenSSL libraries in your Elytron-based SSL/TLS configuration, use the following command. To use the OpenSSL libraries in your legacy security subsystem SSL/TLS configuration: The different OpenSSL protocols that can be used are: openssl.TLS openssl.TLSv1 openssl.TLSv1.1 openssl.TLSv1.2 JBoss EAP will automatically try to search for the OpenSSL libraries on the system and use them. You can also specify a custom OpenSSL libraries location by using the org.wildfly.openssl.path property during JBoss EAP startup. Only the OpenSSL library version 1.0.2 or greater provided by JBoss Core Services is supported. If OpenSSL is loaded properly, you will see a message in the server.log during JBoss EAP startup, similar to: A.40. Comparison of validation timing methods You can compare different aspects of the validate-on-match and background-validation methods to determine which method is suitable for configuring database connection validation. The following table includes a comparison matrix for validation timing methods: Table A.133. Comparison matrix for validation timing methods Comparison aspect Validate-on-match method Background-validation method Reliability The validate-on-match method validates immediately before the use of each database connection. This means validation is performed to test the connections that are checked out of the pool for use by the application. The background-validation method is less reliable because connections might fail between the periodic background validation and the time involved in the use of validated connections. When the background validation method runs frequently, the validation is performed only for those connections in the pool, which are not reserved by the application for use. This also means no validation is performed to test connections that are checked out of the pool for use. Performance, which depends on the use of the system, network performance, and the timing and scope of any connectivity issues Users of systems that remain idle for long periods are more likely to see brief or longer delays when requesting connections using validate-on-match . Users of systems with a more efficient validation mechanism, such as the JDBC 4 validation mechanism may notice fewer delays when using validate-on-match . This is true if the system is rarely idle and connections are less likely to time out. Following a wide-spread outage that impacts most or all of the connections in the pool, users of datasources configured with validate-on-match are more likely to encounter delays in getting connections. This is because the broken connections are iteratively validated and evicted when the user waits for a connection. Users of systems that remain idle for long periods are less likely to see brief or longer delays when requesting connections using background-validation . Users of systems with a more efficient validation mechanism, such as the JDBC 4 validation mechanism may notice fewer delays when using background-validation . This is true if the system is rarely idle and connections are less likely to time out. Following a wide-spread outage that impacts most or all of the connections in the pool, users of datasources configured with background-validation are more likely to encounter broken connections that need to be returned and retried multiple times. Coding for fault tolerance In case of any fault, the application logic remains the same when using validate-on-match because a connection can be externally terminated at any point even after the connection is obtained from the pool by the application. The broken connections are less likely to present when using validate-on-match . This is because validate-on-match performs immediate validation of a connection before its use. In case of any fault, the application logic remains the same when using background-validation because a connection can be externally terminated at any point even after the connection is obtained from the pool by the application. The broken connections are more likely to present when using background validation . A.41. Managed domain reference You can use the following resources to configure JBoss EAP running as a managed domain. Server attributes and child resources A server requires the following attributes and child resources: name : The name of the server. group : The name of a server group from the domain model. A server includes the following optional attributes: auto-start : Whether or not this server should be started when the host controller starts. socket-binding-default-interface : The socket binding group default interface for this server. socket-binding-group : The socket binding group to which this server belongs. socket-binding-port-offset : An offset to be added to the port values given by the socket binding group for this server. update-auto-start-with-server-status : Update the auto-start attribute with the status of the server. A server group includes the following child resources: interface : A list of fully-specified named network interfaces available for use on the server. jvm : The JVM settings for this server. If not declared, the settings are inherited from the parent server group or host. path : A list of named file system paths. ssl : SSL/TLS configuration for when the server instance is connecting back to its host controller. system-property : A list of system properties to set on this server. Server group attributes and child resources A server group requires the following child resources: name : The server group name. profile : The server group profile name. socket-binding-group : The default socket binding group used for servers in the group. This can be overridden on a per-server basis. A server group includes the following optional attributes: graceful-startup : Start the servers gracefully, queuing or cleanly rejecting incoming requests until the server is fully started. By default true . management-subsystem-endpoint : Set to true to have servers belonging to the server group connect back to the host controller using the endpoint from their remoting subsystem. The remoting subsystem must be present for this to work. socket-binding-default-interface : The socket binding group default interface for this server. socket-binding-port-offset : The default offset to be added to the port values given by the socket binding group. A server group includes the following child resources: deployment-overlay : Links between a defined deployment overlay and deployments in this server group. deployment : The deployment content to be deployed on the servers in the group. jvm : The default JVM settings for all servers in the group. The host controller merges these settings with any other configuration provided in host.xml to derive the settings used to launch the server's JVM. system-property : The system properties to be set on servers in the group.
