Overview of the Operations Manager

OM controls the operations of an IMSplex. OM provides an application programming interface (the OM API) through which commands can be issued and responses received. With a single point of control (SPOC) interface, you can submit commands to OM. The SPOC interfaces include the TSO SPOC and the REXX SPOC API. You can also write your own application to submit commands.

OM provides the following functions to an IMSplex:

• Routes IMS commands to IMSplex members registered for the command.
• Consolidates command responses from individual IMSplex members into a single response and provides that response to the originator of the command.
• Provides an API for automated operator commands.
• Provides a general use interface to register commands to support any command processing client.
• Provides user exits for command and response edit and command security.

OM log records can be written to a z/OS® System Logger log stream by specifying the AUDITLOG= parameter of the IMSPLEX() keyword on the CSLOIxxx PROCLIB member. The log records are an audit trail of command input, associated command output, and unsolicited message output.

One OM must be defined in the IMSplex to use OM functions. Each z/OS image can have more than one OM. If multiple OMs are defined in the IMSplex, any OM defined can perform work from any z/OS image in the IMSplex.
