APPLID1=name1 parameter for procedures

The VTAM® APPLID is overridden by the APPLIDn= startup parameter, and APPLID3 is always used for the tracking subsystem. You must take care not to cause the same IMS VTAM APPLID to be opened for more than one IMS subsystem. If necessary, the APPLID=(name1,name2,name3) on the COMM macro should all be overridden by using the APPLID1, APPLID2, and APPLID3 parameters to ensure unique APPLIDS.

In a generic resource group environment, the APPLID1 parameter overrides the value that is specified in the first position of the APPLID= field of the IMS COMM macro. Using this execution parameter allows IMS system definitions to be identical by providing a unique APPLID override when starting the IMS job.

If MNPS is used for XRF systems, the APPLID1 and APPLID2 parameters specify the application identification for the APPLID ACB. The MNPS parameter specifies the application identification for the MNPS ACB.
