dbaascli dbpatchm clonedb

The dbpatchm clonedb subcommand of the dbaascli utility is used to apply a patch to a test deployment before you apply it to a live, production database deployment.

Connect to the compute node as the opc user and execute this command as the root user. 

dbaascli dbpatchm --run -clonedb

The dbpatchm clonedb subcommand displays progress information as it copies information from the live deployment to the test deployment and then applies the patch to the test deployment.
