Access and Invoke the IMS APIs

Some IMS commands gather statistic by invoking IMS APIs that are distributed with the IBM IMS libraries.

The following procedure guides you through accessing and invoking the IMS APIs.

Follow these steps:

  1. Add the IMS RESLIB to the SYSVIEW STEPLIB.

    The API modules reside in the IMS RESLIB.

  2. If you invoke CA SYSVIEW from TSO, add the RESLIB to the USER address space and the user TSO logon procedure STEPLIB.
  3. Invoke the IMS APIs using the following commands:
    IMSSPOC

    Invokes the Common Service Layer API.

    IMSSLOGS

    Invokes the IMS DBRC API.

    IMSQSTAT

    Invokes the Common Queue Server API.

    IMSQSUM

    Invokes the Common Queue Server API.

    IMSQTRAN

    Invokes the Common Queue Server API.

The IMS APIs are invoked and you can use the IMS commands to gather statistics.

Note: For more information in the IBM IMS APIs, see The IMS System Programming API Reference.
