Standby database - RMAN level 0 - Recovery catalog - OEM.

Question

We have configured rman level 0 backup from standby database on OEM. Job is running fine, but rman is not getting connected to recovery catalog. RMAN is connecting to target control file instead of recovery catalog. I understand we need to have DG broker configured for primary and standby for RMAN to connect recovery catalog if you run from OEM. We have configured the DG broker also. DG broker configuration is woriing fine. but Still Standby is not connecting the rman recovery catalog database.
Can anyone tell me what i should check.

Answer 1

Catalog database is same for primary and standby. It is not working for both the version. What are all the basic check i need to do to debug the issue.
THIS IS LOG FROM OEM it is not connecting to target. instead of it is connecting to target control file.
