Enabling dynamic definition for MSC resources

Dynamic definition for MSC resources is enabled by specifying MSCRSCS=DYN in the MSC section of the DFSDFxxx member of the IMS PROCLIB data set.

Before you can enable dynamic resource definition for MSC resources, the Common Service Layer (CSL) must be enabled with at least the Structured Call Interface (SCI) and the Operations Manager (OM).

After you enable dynamic resource definition for MSC resources, you can create, modify, and delete MSC resources in an online IMS system by using IMS type-2 CREATE, UPDATE, and DELETE commands.

Any changes that are made to MSC resources dynamically are not saved across a cold start unless you export the modified definitions to the IMSRSC repository or code the changes to the MSC resources into stage-1 system definition macros.

To enable dynamic definition for MSC resources, complete the following steps:

Procedure

  1. Specify MSCRSCS=DYN in the MSC section of the DFSDFxxx member of the IMS PROCLIB data set.
  2. Cold start IMS.
  3. Confirm that dynamic definition is enabled for MSC resources by issuing the QUERY MEMBER TYPE(IMS) command.
    When dynamic resource definition is enabled for MSC resources, the command output includes DYNMSC in the local attributes.
