OM audit trail

The IMS Operations Manager (OM) uses the z/OS® system logger to provide an audit trail. IMS operator commands issued through OM, as well as their command response, are saved to the system logger. In addition, some unsolicited messages from OM, SCI, and IMS are also logged in the audit trail.

All input is logged before OM calls the OM Input user exit. Input is logged upon return from the OM Input user exit only if the exit modified the input.
