Question: How do I identify which Amazon RDS DB parameters are in custom parameter groups and which are in default parameter groups?

How can I identify which Amazon Relational Database Service (Amazon RDS) DB parameters are in a custom parameter group and which are in a default group?Short descriptionYou can modify parameters for custom DB parameter groups to change or to resolve incompatible-parameter issues. You can compare the differences between the custom parameter group settings. Then, you can determine which values are set by default. For example, you can identify which parameters triggered the incompatible-parameters issue by reviewing the default value. Then, you can compare the custom parameter group to the default parameter group for your database engine.

ResolutionNote: If you receive errors when running AWS Command Line Interface (AWS CLI) commands, make sure that you’re using the most recent AWS CLI version.Using the Amazon RDS consoleOpen the Amazon RDS console, and select the Region that contains the RDS DB instance.Choose Parameter Groups from the navigation pane.Choose two parameter groups that you want to compare, and then choose Parameter group actions.Choose Compare Parameters.The result is a Parameter Comparison table that lists of all parameters and values. Review the Parameter Comparison table to see the values of parameters for both default and custom parameter groups.Using the AWS CLIUse the AWS Command Line Interface (AWS CLI) to compare parameter groups by using the describe-db-parameters and describe-db-cluster-parameters commands.Run the following command to view the settings for a parameter group, including the source for each:aws rds describe-db-parameters --db-parameter-group-name INSERT-YOUR-PG-NAME-HERE --region INSERT-REGION-HERETo list the default value for the engine family, you can use the same command or use the describe-engine-default-parameters command for database-level parameters and the describe-engine-default-cluster-parameters command for cluster-level parameters.The following example shows the default parameters for the MySQL engine version 5.6 parameter group family:aws rds describe-engine-default-parameters --db-parameter-group-family mysql5.6Note: There isn't an AWS CLI command that compares two parameter groups at the same time. This feature is available only in the Amazon RDS console. But you can use the AWS CLI command --output text to list in plaintext instead of the default JSON format. Then, you can compare the plaintext files that list the parameter groups.

Question: Why can't I connect to my AWS Cloud9 environment using an Amazon EC2 instance that's running Amazon Linux 2 as the jump host?

When I try connecting to my AWS Cloud9 environment using an Amazon Elastic Compute Cloud (Amazon EC2) instance, I receive a connection error. The Amazon EC2 instance is running Amazon Linux 2 as the jump host. Why can't I connect?Short descriptionAWS Cloud9 uses the netcat (nc) command to connect to a jump host (also known as a jump server). However, netcat isn't installed by default on Amazon EC2 instances running Amazon Linux 2 as the jump host.To connect your AWS Cloud9 environment to a jump server, you must manually install the netcat package on your Amazon EC2 instance.Resolution1.    Use the Linux command line interface (CLI) to install the netcat package on your Amazon EC2 instance by running the following nc command:yum install nc2.    Verify that the user account ec2-user has a PATH to the location of the nc command.

Question: How can I disable automatic backups in Amazon EFS and remove the stored backup data?

I want to disable the automatic backup feature on my Amazon Elastic File System (Amazon EFS) and remove previously backed-up data. How can I do this?Short descriptionBy default, Amazon EFS creates backups of your data automatically. The backed-up data is stored as a recovery point available through AWS Backup. If you try to remove the recovery point, you receive the following error message:"Access Denied: Insufficient privileges to perform this action. Please consult with the account administrator for necessary permissions."Warning: It's a best practice to keep Auto-Backup enabled. In the case of accidental data deletion, Auto-Back allows restoration of your file system content to the date of the last recovery point created.Note: To perform the steps in the Resolution, you must have AWS Identity and Access Management (IAM) permissions to edit your EFS policies. To revise IAM policy settings, you must have Admin rights. For example, you can perform these actions using your AWS account root user, or by using an admin role. For more information, see Allow all IAM actions (admin access).

ResolutionDisable the automatic backup featureFor information on how to turn off automatic backups, see the Turning automatic backups on or off for existing file systems section in Automatic backups.Delete the recovery point1.    Open the AWS Backup Management console.2.    Select aws/efs/automatic-backup-vault. The Backups section contains completed backups for your file system listed as Recovery Points.3.    By default, the Access policy is set to deny deletions, as shown in the following example policy:{    "Version": "2012-10-17",    "Statement": [        {            "Effect": "Deny",            "Principal": {                "AWS": "*"            },            "Action": [                "backup:DeleteBackupVault",                "backup:DeleteBackupVaultAccessPolicy",                "backup:DeleteRecoveryPoint",                 "backup:StartCopyJob",                "backup:StartRestoreJob",                "backup:UpdateRecoveryPointLifecycle"             ],            "Resource": "*"        }     ]}In the Access Policy section, change "Effect": "Deny" to "Effect": "Allow":{    "Version": "2012-10-17",    "Statement": [        {            "Effect": "Allow",            "Principal": {                "AWS": "*"            },            "Action": [                "backup:DeleteBackupVault",                "backup:DeleteBackupVaultAccessPolicy",                 "backup:DeleteRecoveryPoint",                 "backup:StartCopyJob",                "backup:StartRestoreJob",                "backup:UpdateRecoveryPointLifecycle"             ],            "Resource": "*"        }     ]}Note: Changing Effect to "Allow" means that the user can perform any listed delete actions.

Question: "When I try to load a CSV file into Amazon Redshift using COPY, nothing is loaded"

I'm trying to load a CSV file from Amazon Simple Storage Service (Amazon S3) into Amazon Redshift using the COPY command. However, nothing is loaded and no errors are returned, even though the file contains records. How do I resolve this?ResolutionCOPY fails to load data to Amazon Redshift if the CSV file uses carriage returns ("\r", "^M", or "0x0D" in hexadecimal) as a line terminator. Because Amazon Redshift doesn't recognize carriage returns as line terminators, the file is parsed as one line. When the COPY command has the IGNOREHEADER parameter set to a non-zero number, Amazon Redshift skips the first line, and therefore, the entire file. No load errors are returned because the operation is technically successful.To resolve this problem, replace carriage returns with CRLF ("\r\n" or "0x0D0A" in hexadecimal) or LF (“\n” or “0x0A” in hexadecimal). Upload the modified file to the S3 bucket, and then try the COPY command again.<b>Additional troubleshooting tips</b>Verify whether you are experiencing a lock resource contention when using the COPY command. For more information, see How do I detect and release locks in Amazon Redshift?Confirm whether there is contention in your Workload Manager (WLM). You can use the STV_WLM_QUERY_STATE query to confirm whether the COPY command is trying to acquire a WLM slot.Check whether the COPY transaction is being rolled back. To confirm the rollback, use the SVL_STATEMENTTEXT and STL_UNDONE views.
