Error description
Transaction manager transaction class (TCLASS) statistics for field XMCTAPT are incorrect. Field XMCTAPT represents: The number of separate times that the purge threshold of the transaction class has been reached (times at purge threshold). The report shows column 'Times PrgThr ' has a value of 1 incorrectly. When a transaction class is defined and installed and has been configured with a Purge Threshold value of exactly 1 then the number of times at purge threshold is incorrectly also set to a value of 1.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users * **************************************************************** * PROBLEM DESCRIPTION: CICS Transaction Manager statistics * * field XMCTAPT is incorrect when used * * with a Transaction Class defined with * * PURGETHRESH=1. * **************************************************************** * RECOMMENDATION: * **************************************************************** The CICS Statistics field XMCTAPT, representing the number of times a transaction class has reached its purge threshold, reports incorrect values when viewed for a transaction class which specifies PURGETHRESH=1. Setting the PURGETHRESH value to 1 means that any transaction which queues for membership of the transaction class will be purged. When a transaction class is installed with PURGETHRESH=1, or modified to PURGETHRESH=1 from another value, or a statistics reset is performed, then the XMCTAPT statistics field will report that the transaction class has been at its purge threshold, even though no work may have run in that transaction class. Furthermore, the value of XMCTAPT was not correctly incremented when the max active limit was reached. A transaction class with PURGETHRESH=1 is at its purge threshold when the MAXACTIVE value is reached.
Problem conclusion
DFHXMCL and DFHXMST have been updated to ensure that the times at purge threshold statistic (XMCTAPT) is set correctly for transaction classes which specify PUGETHRESH=1.
