Maintaining message destination resource information

When the RM uses a resource structure in an IMSplex, you can indicate that IMS shares IMS Transaction Manager resources. This message destination resource information includes terminals, users, user IDs, LTERMs, MSNAMEs, and APPC descriptors.

To maintain message destination resource information, specify STM=YES on the DFSDCxxx member of the IMS PROCLIB data set. See IMS Version 15.4 System Definition for more information about DFSDCxxx.

See Planning for Transaction Manager resources in an IMSplex for more information on TM Resources.
