Create a physical standby in 10g with Data Guard. MRPO process indicates WAIT_FOR_GAP.

I am new at my company and I am trying to fix a broken 10.2.0.5.0Physical Standby.  Protection Mode: MaxPerformance

After executing the rman duplicate from disk I have several issues:

The redo logs are not being applied.

  1. The MRPO process indicates WAIT_FOR_GAP.
  2. I have an ORA-16009: remote archive log destination must be a standby.
  3. I have a heartbeat failed to standby. It is set to point to the production instance.

(Q)Since I am using Data Guard, do I have to execute the below command from a DGMRL command line?

alter database recover managed standby database disconnect from session;

Howdy, Stranger!
