Starting products

You must start the products after you complete the other configuration tasks that are described in this section.

To start the products

  1. Update the IMS control or DBCTL region, if applicable, to include the APF-authorized library in the STEPLIB concatenation. The APF-authorized library must precede the IMS RESLIB in the STEPLIB concatenation.


    BMC recommends that you execute the IMS system from a STEPLIB or JOBLIB.

    If it is unacceptable at your site to execute IMS from a STEPLIB or JOBLIB, you must use ddname BMCRESLB to allocate the IMS RESLIB that is accessed from the LINKLIST to IMS. In addition, the DELTA PLUS APF-authorized library must be in the BMCRESLB concatenation.

  2. Start BMCXLINK.

    BMCXLINK allows users to communicate with an IMS system. TSO-based users of IMS and the product do not have to run on the same CPU. DLPCNTL member DLP#LINK provides sample JCL for BMCXLINK.


    The BMCXLINK task must have WRITE access authority to the Log and History File data sets.

  3. Process the CPU ID password (either bypass or permanent) that will allow the product to work.

    For more information, see the installation guide.

  4. Cold start IMS.
