OMS

The status command provides more details for the OMS environment. These include:

·     Target database session count – The number of database connections established under the Databases folder in the navigator component of OEM.

·     Operations queued for processing – Indicates the number of operations that are waiting to be processed.  The activities may include sending e-mail, deleting events, submitting jobs, etc.

·     Number of OMS systems in domain – Displays the number of OMS servers running.  Multiple OMS servers can be created for scalability in large environments.

·     Number of administrators logged in – The number of OEM administrators logged in to the OMS.

·     Repository session pool depth – The number of database sessions reserved for OMS to submit jobs and register events. The default is 15 sessions and can be increased when heavy activity occurs.

·     Repository session count – The number of repository sessions currently in the pool.  The OMS requires 7 sessions on startup.  A repository session is needed to access information in the OEM repository.  A specific number of sessions are retained in a pool to keep OMS from re-opening and closing sessions – a resource consumer.  This parameter is not modifiable.

Stopping the OMS is performed by the command below.  The stop command also requires the username and password. 

oemctl stop oms <EM Username>/<EM Password>
