Error description
Fields MAXLATNT, MINLATNT and TOTLATNT in SMF116 records are filled with zeroes after migrate to Websphere MQ for z/OS Ver.9.0. The latency fields are not being collected because of an incorrect check in CSQMCPRH, which is only creating the WWFR control block for the task if class 1 accounting is active. In the customer case, class 3 is active, but class 1 is not.
Local fix
Work around this problem by also starting class 1 accounting trace.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: SMF116 records 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, it only checks if class 1 accounting trace is enabled. If class 3 is enabled, but class 1 is not, the lack of the WWFR for the task causes the calculation of some of the SMF 116 fields (for example MAXLATNT, MINLATNT and TOTLATNT) to be skipped.
Problem conclusion
CSQMCPRH is changed to also check for whether class 3 accounting trace is enabled.
