Resource type consistency
Resource type consistency ensures that a name is unique within a group of resources, called a name type. The IMSplex automatically enforces resource type consistency when RM is active and a resource structure is defined in the coupling facility.
IMS enforces resource type consistency for the name type of message destination. IMS ensures that a resource defined as a message destination is consistent across the IMSplex.
Message destinations are the following:
- LTERMs
- LTERMs defined as APPC descriptors
- MSNAMEs
- IMS-defined transactions
- CPI-C transactions
Disabling enforcement of resource type consistency
You can disable the enforcement of resource type consistency when a resource structure is present by specifying STM=NO in the DFSDCxxx PROCLIB member data set. After specifying STM=NO, resource type consistency is enforced only for IMS-defined and CPI-C transactions.
