 Agent needs to be reregistered to the Cloud Backup portal 

 Why it’s happening 

If it still shows that the Agent is offline after a refresh of the Portal page, then the Agent needs to be registered again.

 How to fix it 

Registering an Agent to the Portal retains all existing jobs, schedules, and configurations as-is. Go to the Agent installation directory, then run the register command.

cd opt/BUAgent
./register

Answer the following prompts.



* What is the web-based Agent Console address? cloudbackupregister.service.softlayer.com
* What is the web-based Agent Console connection port [8086]? Press enter, 8086 is the correct port.
* What is the web-based Agent Console username? This entry is the same username that is used to log in to Portal.
* What is the web-based Agent Console password? This entry is the same password that is used to log in to Portal.



For more information about viewing or changing the backup password, see [Managing username and password for the Cloud Backup service](https://cloud.ibm.com/docs/Backup?topic=Backup-changePassword).

If the previous steps don't work, pull up and review the most recent BUAgent-X.XLOG.



1. Go to opt/BUAgent.

cd /opt/BUAgent
2. List the contents and sort them by date.

ls -lrth
3. Find the name of the most recent BUAgent-x.XLOG and open it with /opt/BUAgent/xlogcat. It can't be opened with cat or vim.

./xlogcat BUAgent-1.XLOG
4. Review the log and determine the issue.
Robustness 



 Tradeoffs of the robustness principle 

Jon Postel's [robustness principle](https://en.wikipedia.org/wiki/Robustness_principle) is a fixture of software design and implementation advice. It states:

> Be liberal in what you accept, and conservative in what you send.

In recent years, this counsel has [proven controversial](https://datatracker.ietf.org/doc/html/draft-thomson-postel-was-wrong-03). For a number of reasons, this handbook discourages broad application of the principle. This is a reversal of [previous guidance](https://github.com/ibm-cloud-docs/api-handbook/blob/086d28c9357b39612ceb816130d0f6ad92f82859/design/errors.mdrobustness-tradeoffs).



 Historical meaning 

There are many possible applications of the robustness principle, and its original context (as [highlighted](https://datatracker.ietf.org/doc/html/draft-thomson-postel-was-wrong-03section-2) by Martin Thomson's dissent) is not applicable to new API design:

> While the goal of this specification is to be explicit about the protocol there is the possibility of differing interpretations. In general, an implementation should be conservative in its sending behavior, and liberal in its receiving behavior.

Paraphrased, the narrower, original definition of the robustness principle states that if a protocol's specification exists apart from sundry implementations, a defensive implementor should react to ambiguity (which is a defect of the specification) with:



* A broad interpretation of what constitutes valid input (but still only within the confines of what the specification leaves open to interpretation)
* A narrow interpretation of what constitutes valid output









 Best practices 

When a service team is responsible for developing an API definition and its canonical implementation (the service) in concert, Postel's robustness principle SHOULD NOT be (mis)applied. This section details best practices that contradict adherence to the robustness principle as it is colloquially understood.



 Specificity of validity
However, you must also enable either Classic Access on the VPC, or configure IBM Cloud Transit Gateway to connect the VPC where the VPN server resides.





 What VPN client is supported? 

See [Supported client software](https://cloud.ibm.com/docs/vpc?topic=vpc-client-to-site-vpn-planningvpn-client-software) for details.





 What protocol and port can I use for the VPN server? 

You can use UDP or TCP and any port number to run the VPN server. UDP is recommended because it provides better performance; port 443 is recommended because other ports might be blocked by internet service providers. If you cannot connect to the VPN server from your VPN client, you can try TCP/443 because it is open on almost all internet service providers.





 What route action should I use? 

The action of the VPN route depends on the route destination:



* If the route destination is in the VPC, or an on-premises private subnet connected using VPN gateway, the route action can be deliver; otherwise, it is translate.
* If you want to block traffic from the client, use the drop route action to forward unwanted or undesirable network traffic to a null or "black hole" route.
* When the route action is translate, the source IP is translated to the VPN server private IP before it is sent out from the VPN server. This means that your VPN client IP is invisible from the destination devices.







 What DNS server IP addresses should I use? 

DNS server IP addresses are optional when you provision a VPN server. You should use 161.26.0.10 and 161.26.0.11 IP addresses if you want to access service endpoints and IaaS endpoints from your client.

No. DV SAN certificate configurations are provided to you at no additional charge that is compared with HTTP or HTTPS with a Wildcard certificate.





 Can my CDN created using HTTPS with Wildcard be updated to use a DV SAN certificate? 

No, a wildcard mapping cannot be changed to SAN certificate.





 What is a certificate authority? 

A certificate authority (CA) is an entity that issues digital certificates.





 Which CA does IBM Cloud® CDN service use for issuing a DV SAN certificate? 

IBM Cloud CDN service uses LetsEncrypt certificate authority.





 What SSL certificates are supported for IBM Cloud CDN? 

The SSL certificates that are supported are Wildcard certificate and Domain Validation (DV) Subject Alternate Name (SAN) certificate. The SAN certificate is shared across multiple customers. IBM Cloud CDN does not support uploading custom certificates.





 I received an email asking me to address a Domain Validation challenge that is related to my CDN. What do I do now? 

Domain Validation can be addressed in one of three ways: CNAME, Standard, or Direct.

For details on how to address any of these, refer to the [Completing Domain Control Validation for HTTPS](https://cloud.ibm.com/docs/CDN?topic=CDN-completing-domain-control-validation-for-https-with-dv-saninitial-steps-to-domain-control-validation) document.





 What will happen if I don't address the challenge for domain validation of my CDN? 

If the mapping's state is in DOMAIN_VALIDATION_PENDING state for more than 48 hours, the mapping creation is cancelled, and the mapping's state will be CREATE_ERROR. And in this state, you can choose to Retry creation or delete the mapping.





 Does a Wildcard certificate need to validate a domain for my CDN? 

No, but you can only use the CNAME to retrieve content from your origin. For example, https://www.example-cname.cdn.appdomain.cloud.





 I received an email indicating that my domains is not pointed to IBM CDN CNAME. What do I do now? 

This email means that your CDN is not being used.

The value returned for my targeted flag or property is not what I expected. 

  What’s happening 

Feature flag is targeted with segment rules. Rule execution is not as expected.

  Why it’s happening 

Targeting assigns flag or property values to segments by evaluating rules.

Targeting rules are executed in the order listed in the Edit targeting view. If a segment appears in more than one rule, only the value defined by the last rule is assigned.

  How to fix it 

Correct the order of evaluation by using the up- and down-arrows in the Edit targeting view, or remove the segment causing the unexpected outcome from rules.

 Credentials are required to open a trace or memory dump window (Deprecated) 

 What’s happening 

A user name and password are required to open the trace or memory dump window.

 Why it’s happening 

This problem occurs because of the login session timeout.

 How to fix it 

Enter the user name and password again.





 Error occurs when trace or memory dump operations are running (Deprecated) 

 What’s happening 

An error message is displayed while the trace or memory dump operations are running. The message indicates that a target instance for an app isn't in the running state:

Instance 0: Trace specification is set successfully
Instance 2: Trace specification is set successfully
Instance 1: Target instance 1 for app abcd is not in the running state.
Instance 3: Trace specification is set successfully
Instance 4: Trace specification is set successfully

 Why it’s happening 

This problem occurs for the following reasons:



* The trace or dump management capabilities are only for app instances that are running. Trace or dump operations can't be used on app instances that are stopped, starting, or crashed.
* The status of the app instance is changing when the trace or dump dialog is opened.



 How to fix it 

Close the window, then open it again.





 Instances have different traceSpecification configurations (Deprecated) 

 What’s happening 

For different instances of one app, you might see different traceSpecification configurations.

 Why it’s happening 

This behavior occurs for the following reasons:



* You changed the configuration for one or more instances previously. If you change the traceSpecification configuration for one instance, the change doesn't apply to other instances of the same app. For example, your app uses log4j and you have 2 instances for this app. You can change the log level of instance 0 from info to debug, but the log level of instance 1 remains as info.



 How to fix it 

No action is required. This behavior is expected.





 Disk quota exceeded 

You might see, in your app log, that your disk quota is exceeded.

 What’s happening
If you have extra compliance requirements such as NIST 800-88 Guidelines for Media Sanitization, you must perform data sanitation procedures before you delete your volumes. For more information, see the [NIST 800-88 Guidelines for Media Sanitation](https://csrc.nist.gov/publications/detail/sp/800-88/rev-1/final).
* What rules apply to volume names and can I rename a volume later on?

 What rules apply to volume names and can I rename a volume later on? 

Valid volume names can include a combination of lowercase alphanumeric characters (a-z, 0-9) and the hyphen (-), up to 63 characters. Volume names must begin with a lowercase letter and be unique across the entire VPC infrastructure.

You can change the name of an existing volume in the UI. For more information, see [Managing Block Storage for VPC](https://cloud.ibm.com/docs/vpc?topic=vpc-managing-block-storagerename).
* Does the volume need to be pre-warmed to achieve expected throughput?

 Does the volume need to be pre-warmed to achieve expected throughput? 

You do not have to pre-warm a volume. You can see the specified throughput immediately upon provisioning the volume when you create the volume from an image. You can experience degraded performance when you provision the volume by restoring a snapshot.
* What is a Block Storage for VPC snapshot?

 What is a Block Storage for VPC snapshot? 

Snapshots are a point-in-time copy of your Block Storage for VPC boot or data volume that you manually create. The first snapshot is a full backup of the volume. Subsequent snapshots of the same volume capture only the changes since the last snapshot. For more information, see [About Block Storage for VPC Snapshots for VPC](https://cloud.ibm.com/docs/vpc?topic=vpc-snapshots-vpc-about).
* What is a backup snapshot?
