A Active Standby Pair Example

This appendix provides an example showing you the complete process for deploying and running your active standby pair of TimesTen databases in the Kubernetes cluster. After the databases are up and running, the example demonstrates how the Operator controls and manages the databases. If the active database fails, the Operator performs the necessary tasks to failover to the standby database, making that standby database the active one. The example concludes with procedures to delete the TimesTen databases and to stop the Operator.

Note:

You have the option of using Helm to deploy your active standby pair of TimesTen databases. For more information about using Helm, see Use Helm to Deploy the TimesTen Kubernetes Operator and TimesTenClassic Objects.
