After deploying a number of Cloud Control agents recently, a few of the agents started generating critical events with a nasty looking (and unhelpful) error message:
Message=Internal error detected: java.lang.IllegalStateException:oracle.sysman.gcagent.target.interaction.execution.ConfigStateMgr:798.
Whilst the error above isn’t too friendly, it stems from errors with the collection of storage metrics. Further details are logged under the agent’s home:
(grep for “storage_reporting_data”)
This is published as bug 13547855 in MOS and can be easily resolved by doing the following:
export AGENT_HOME=/u01/app/oracle/agent12c cd $AGENT_HOME/agent_inst/sysman/emd/state/configstate/host/* tar -cvf storage-xmls.tar storage_*.xml rm storage_*.xml
After a while, you should find that the errors stop 🙂
