    Lost emkey.ora

      We have an 11g on Linux. The previous DBA left silently and I need to dig out what are there. One of the problem is Enterprise Manager. I believe we are use database control not grid control. Have problem to make it work

      emctl Start dbconsole - ok

      go to web browser to connect to the service, get message:
      Service is not initialized correctly. The Em Key is not configured properly. Run "emctl status emkey" for more details

      [oracle@cchdb config]$ emctl status emkey
      Oracle Enterprise Manager 11g Database Control Release

      Please enter repository password:

      The Em Key is not configured properly or is corrupted in the file system and does not exist in the Management Repository. To correct the problem:
      1) Copy the emkey.ora file from another OMS or backup machine to the OH/sysman/config directory.
      2) Configure the emkey.ora file by running "emctl config emkey -emkeyfile <emkey.ora file location>".

      Not sure if there is 1 or more OMS installed. What is the best to do next?

      Related questions:
      1) how to I find if there are OMS installed or running? what is OMS the installation location and process on Linux.
      2) If recreate repository, would it be created in the target database, or another database dedicated to OEM?

        • 1. Re: Lost emkey.ora
          check emkey.ora exist in the OH/sysman/config/emkey.ora
          also if not there then check in the repos it exist or not
          and if both places it not there then you have to remove the dbconsole and configure it again

            I appreacte you reply.

            emkey.ora is not in OH/sysman/config, nor the repository. I am planning to do as you sugegsted.

            To remove the dbconsole, did you mean to run emca -deconfig?

            To configure dbconsole, using emca -config, I guess, should I use -config create or recreate. The manual says that create/recreate will create a database to hold the repository. If I priovide my target database SID for the parameter, will the target database get dropped/recreated, or just overwrittern the SYSMAN schema?

            • 3. Re: Lost emkey.ora
              you need to follow the steps as below

              emca -deconfig dbcontrol db -repos drop
              emca -config dbcontrol db -repos create
              • 4. Re: Lost emkey.ora
                I tried to deconfig like below:
                [oracle@cchdb archivelog]$ emca -deconfig dbcontrol db -repos drop

                It took quite long time and block any connections to the database (session already open can still query the database).

                Did I do anything wrong?

                  Please stop the running dbconsole/isqlplus, bounce the database and try again
                  • 6. Re: Lost emkey.ora
                    Yes. This works. I drop/create the repository and beable to see the OEM page. But in the welcome page, it says

                    Oracle Enterprise Manager Database Console
                    Accessibility Mode Disabled

                    Why the Accessibility Mode is disabled. Is this the right mode?

                          Thanks, I had a problem setting up EM on my laptop - the console service was not starting after the domain on my laptop was changed. Your tip did the trick.
