CICS TS 5.4 requires IBM PTF UI59082 for the SM/SWAP to work correctly. Without the PTF, applications running in SM/SWAP that share Temp Storage Queues (TSQ), can ABEND or have other data integrity issues as a result of the TSQ not having unique names for each session. 

The PTF corrects when the call to global user exit XTSEREQ was made. The XTSEREQ exit was being called too late to allow changing the TS QUEUE or QNAME value.
