    JGUPTA
      Hi,

      I tried to login on OEM 12c release 2 cloud control console as other user it show the following error
      Authentication failed. If problem persists, contact your system administrator
      but when i try with sysman account then it successful done. so i dont know why it happen. I also checked job_queue_processes that is 1000 and i also checked listener,agent,oms status all are up.
      so please suggest me what should i do and what is the main cause of this problem.

      Thanks,
      Jimmy Gupta

          Hi Jimmy Gupta,

          Verify the following:

          1. lsnrctl status

          2. Verify the following document:
          12.1.0.2 : Login to Console Fails With "Authentication failed. If problem persists, contact your system administrator." (Doc ID 1493151.1)

          3. If nothing works, emoms.trc file would help us to understand the error tracked during the login.

          Regards,
          Venkat

            lsnrctl status is up

            according to Doc ID 1493151.1 it provide the two method for solving this issue.
            1. Set the job_queue_processes to a non-zero value but in my case the value is alredy =1000

            SQL> show parameter job

            NAME TYPE VALUE
            ------------------------------------ ----------- ------------------------------
            job_queue_processes integer 1000

            and

            2.SQL> update mgmt_audit_master set prepopulate_days=5 where prepopulate_days is null;
            SQL> exec mgmt_audit_admin.add_audit_partition;

            but when i execute the above statement it gave me a following error

            SQL> update mgmt_audit_master set prepopulate_days=5 where prepopulate_days is null;
            update mgmt_audit_master set prepopulate_days=5 where prepopulate_days is null
            *
            ERROR at line 1:
            ORA-00942: table or view does not exist

            so what that mean and what is the default location of emoms.trc file.

            Thanks,
            Jimmy

                  What user are you trying to login as?
                  Can you login as sysman?
                  Did you create the user via EM?
                  Have you ever been able to login as this user?
