an affinity of LUNAME and a lifetime of PCONV. The presence of one group rather than a group for each application is actually not important. When dynamic routing, the affinity still ends when the current pseudoconversation ends, so the effect is exactly the same.

It is useful to have applied the PTF for CSP APAR PN45100, because this adds deletion of 'EZExtttt' TS queues after a transaction abend.

SPI commands

There are transaction-system affinities in the report indicating that commands such as EXTRACT EXIT and INQUIRE SYSTEM have been used. These are concerned with establishing the correct environment for a transaction. The programs involved are DCBINIT and DCBRINIT.

Transaction-system affinity can mean that a transaction is tied to a particular CICS, or more likely, as in this case, that the transaction should be run on all cloned CICS regions. Because it happens automatically there is no affinity problem. If multiple CICS regions are cloned, each cloned CICS region must perform this processing and will do so, but this may have no effect on any of the other CICS regions.
