    Grid12c Unable to start (Backend WLS or EM application seems to be down)

      [oracle@gridctrltxt bin]$ ./emctl start oms

      Starting Oracle Management Server...
      Oracle Management Server is not functioning because of the following reason:
      A recent plug-in upgrade operation has failed. Follow these steps to recover:

      1. Restore/recover the repository database (For example from a backup)
      2. Start the Management server using 'emctl start oms' command. Oracle Management Server cannot be started without recovering the repository database.

      Execute 'emctl status oms -details' to get further information about this failure. After identifying and fixing the issues reported in log files you can retry plug-in upgrade.

      For more details, Refer to 'Plug-in Deployment' section in the Enterprise Manager Advanced Configuration Guide

      Please help me resolve this issue.

          Hi,

          Observations:

          A recent plug-in upgrade operation has failed. Follow these steps to recover.

          Confirmations:

          Let us know if you have performed any of the plug-in deployments recently?

          Action Plan:

          Generally if any plug-in deployment was failed, and when you try to restart the OMS, it fails with this error message as there would be some flag set at repository that states the earlier plug-in deployment was failed.

          This can be determined by checking the files under the following locations:

          <OMS_HOME>/cfgtoollogs/pluginca/*

          + I would suggest to log a service request to analyze the issue further and get it solved.

          Best Regards,
          Venkat

            Hi Venkat,

            The issue has been resolved with the help of Oracle Support.
            We did the following:

            $create table mgmt_parameters_bk as (select * from mgmt_parameters);

            $delete from mgmt_parameters where parameter_name like '%PLUGIN%';
            $commit;

            $emctl stop oms -all
            $emctl start oms

            Note: Do NOT use this without guidance of Oracle Support.
            Backup the repository db before attempting Plugin Upgrade.
            It is mandatory to apply BP1 Patch 13242773 to OMS before Upgrading Plugins to 12.1.0.2

            Thank you for your suggestion and help.
