12.2.0.1 : Multi Instance Redo Apply

As we all aware , that we can have only one instance of Standby running with MRP (redo apply) running in RAC environments.

Starting 12.2.0.1, we can have multiple instances on standby side too with following command.

Generally, to start the MRP process we use,

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

Now this has been enhanced in 12.2.0.1 to run MRP on all stand by instances.

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION INSTANCES ALL;

Now this has been enhanced in 12.2.0.1 to run MRP on specific number of instances, Please note you cannot choose which instances to run.

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION INSTANCES 2;

And you can check in v$recovery_progress view in each instances as MRP is running on them for redo sync

-Thanks

Suresh
