Plugin versions on agent does not support target type oracle_pdb

It seems a bug.

Tried to add a CDB database with PDBS into 12c OEM, and got the following errors.

Failed RACTEST : Plugin versions on agent https://oemnode1:3872/emd/main/  does not support target type oracle_pdb

 Actually there is another CDB database of same cluster has been added onto OEM months ago. So the error message is misleading.

Below actions were taken, then CDB database was added onto OEM successfully.

  1.  Shutdown and startup CDB database with all PDBS  open.
  2. Bounced OEM agent.
  3. Manually added cluster DB, cluster DB instances, and pluggable databases successfully.
