Error description
Fields MAXLATNT, MINLATNT and TOTLATNT in SMF116 records are filled with zeroes after migrate to IBM MQ for z/OS Ver.9.0, for some queues. From the SMF data and dump I can see there is another codepath that can result in the WWFR control block not being created when only Class 3 accounting is enabled.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: SMF116 records for CICS transactions * * contain incorrect or missing data when * * only class 3 accounting trace is * * enabled. * **************************************************************** When CSQMCPRH checks whether it needs to allocate a WWFR control block for the current task due to Class 3 accounting trace being enabled, it only does so for QRPL requests from RMID's other than MMC. In CICS environments, when an ACE/EB is reused from the MCLB free chain it is possible that no WWFR will have been allocated and for only MMC related requests to be processed. In this situation the WWFR is never allocated, and so the affected fields are not correctly populated.
Problem conclusion
CSQMCPRH is changed to allocate the WWFR if accounting class 3 is enabled, for all QRPL requests.
