Figure 3. Detector components

You are recommended to run the Detector on stable CICS regions only. Do not

apply maintenance to application programs while the Detector is running. Such

maintenance may introduce or remove affinities, thus rendering collected data

inaccurate.

What is detected

The Detector detects the EXEC CICS commands listed in Table 1 on page 11 that

can cause transaction affinity. For ENQ and DEQ commands, the Detector

distinguishes between ENQ by name and ENQ by address based on the presence

of a length parameter on the EXEC CICS ENQ command. It does the same for

DEQs. The reports show which ENQs and DEQs are by name and which are by

address.

It also detects:

vThe end of pseudoconversations, by detecting when one of the transactions in the pseudoconversation terminates without issuing an EXEC CICS RETURN TRANSID command with a non-zero transaction identi®er. If a pseudoconversation ends, and the resource shared by transactions that take part in the affinity still exists, the lifetime of the affinity must be greater than PCONV.
