Resource name uniqueness

When Resource Manager (RM) is active and a resource structure is defined, IMS automatically enforces name uniqueness for certain TM resources.

The TM resources for which IMS enforces name uniqueness include:
  • VTAM® LTERMs
  • VTAM single-session nodes
  • User IDs
  • Users

You can disable the enforcement of resource name uniqueness, and TM resource sharing in general, by specifying STM=NO in the DFSDCxxx PROCLIB member.
