Symptoms

Pluggable database (PDB) target status shows as Availability Evaluation Error in Enterprise Manager (EM) 13c Cloud Control after upgrading EM Agents to 13c.
Some container database (CDB) targets are similarly affected.

 

Checking the <agent instance base>/agent_inst/sysman/log/gcagent.log, the following errors appear for numerous targets:

2017-12-12 19:23:50,162 [1252:GC.DPExecutor.181 (CDynamic:oracle_pdb.XXXXXX_PDB_NAME)] ERROR - Error loading target [oracle_pdb.XXXXXX_PDB_NAME] (CDBTargetGuid, PDBGuid)
oracle.sysman.gcagent.metadata.InvalidMetadataException: A non-optional instance properties [CDBTargetGuid, PDBGuid] is missing from target [oracle_pdb.XXXXXX_PDB_NAME]

Obtaining the status of that target from the EM Agent gives thsi result: 

./emctl status agent target XXXXXX_PDB_NAME,oracle_pdb

Target [CUSTOMER_PDB_NAME,oracle_pdb] does not exist or is broken
---------------------------------------------------------------
Agent is Running and Ready
