Enabling dynamic definition for IMS resource groups

Before you can dynamically add, change, or delete a particular type of IMS resource, you must first enable dynamic resource definition for the resource group that includes the resource type.

You can enable dynamic definition for the following groups of IMS resources:
  • MODBLKS resources, which include definitions for certain runtime attributes of application programs, databases, Fast Path routing codes, and transactions.
  • MSC resources, which include definitions for MSC physical links, logical links, logical link paths, and remote terminals.
Restriction: Dynamically defined MSC resources cannot be used with an RDDS.
Requirement: The dynamic definition of IMS resources requires the Common Service Layer (CSL) with at least the Structured Call Interface (SCI) and the Operations Manager (OM).
The CSL can be enabled by parameters in either of the following members of the IMS PROCLIB data set:
  • The DFSDFxxx member, in the COMMON_SERVICE_LAYER section.
  • The DFSCGxxx member. The CSL values in the DFSCGxxx member override the values in the COMMON_SERVICE_LAYER section of the DFSDFxxx member.
