Starting Oracle Management Server...
Oracle Management Server is still in the process of getting started
Timed out waiting for Oracle Management Server to start
Oracle Management Server is Down
Kindly guide me for this issue.
Not a known case.
Once try to cleanly kill all the process and bring the OMS up and verify the status:
1.Stop the OMS
<OMS_HOME>/bin>./emctl stop oms -all
2.Check if Admin server or Managed Server processes are still running and kill them if any found:
$ps -ef | grep EMGC_ADMIN
$ps -ef | grep EMGC_OMS1
3.Start the OMS
<OMS_HOME>/bin>./emctl start oms
I notice that you are on version 18.104.22.168. First you should upgrade the latest version (22.214.171.124) and apply all recommended patches. If this problem persists after upgrading I would recommend logging an SR with Oracle Support so that they can diagnose the root cause.
