Converting a Multi-AZ deployment to a Single-AZ deployment in RDS Custom for Oracle

Note

End of support notice: On March 31, 2027, AWS will end support for Amazon RDS Custom for Oracle. After March 31, 2027, you will no longer be able to access the RDS Custom for Oracle console or RDS Custom for Oracle resources. For more information, see RDS Custom for Oracle end of support.

You can modify an existing RDS Custom for Oracle DB instance from a Multi-AZ to a Single-AZ deployment.

Console

To modify an RDS Custom for Oracle DB instance from a Multi-AZ to Single-AZ deployment

  1. Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

  2. In the Amazon RDS console, choose Databases. The Databases pane appears.

  3. Choose the RDS Custom for Oracle DB instance that you want to modify.

  4. For Multi-AZ deployment, choose No.

  5. On the Confirmation page, choose Apply immediately to apply the changes immediately. Choosing this option doesn't cause downtime, but there is a possible performance impact. Alternatively, you can choose to apply the update during the next maintenance window. For more information, see Using the schedule modifications setting.

  6. On the Confirmation page, choose Modify DB Instance.

AWS CLI

To modify a Multi-AZ deployment to a Single-AZ deployment by using the AWS CLI, call the modify-db-instance command and include the --no-multi-az option. Specify the DB instance identifier and the values for other options that you want to modify. For information about each option, see Settings for DB instances.

Example

The following code modifies mycustomdbinstance by including the --no-multi-az option. The changes are applied during the next maintenance window by using --no-apply-immediately. Use --apply-immediately to apply the changes immediately. For more information, see Using the schedule modifications setting.

For Linux, macOS, or Unix:

aws rds modify-db-instance \
    --db-instance-identifier mycustomdbinstance \
    --no-multi-az \
    [--no-apply-immediately | --apply-immediately]

For Windows:

aws rds modify-db-instance ^
    --db-instance-identifier mycustomdbinstance ^
    --no-multi-az ^
    [--no-apply-immediately | --apply-immediately]

RDS API

To modify a Multi-AZ deployment to a Single-AZ deployment by using the Amazon RDS API, call the ModifyDBInstance operation and set the MultiAZ parameter to false.
