The SWB count is provided for each queue and for the entire queue manager. The Aborted Sweep Count shows how many sweeps have been aborted for a particular queue. Aborted sweeps occur when the state of a message changes before the sweep is completed and it results in unnecessary pool usage. Displaying the number of aborted sweeps will help customers tune the MQSeries sweeper to avoid unnecessary depletion of long- term pools. SOLUTION: The SWBCount and AbortedSweepCount integer fields have been added to the MoreQDef structure in c$mqmg.h. An integer field named TotSWBCount was added to the MQT_T02 structure in c$mqs.h to keep track of the total number of SWBs being used by the queue manager. Code has been added to the MQ_FileAQueue routine in cmqckq.cpp to set the SWBCount after counting up the SWBs that are in use in the front and rear message lists of a particular queue. Code has also been added to the QM_Checkpoint routine in cmqckp.cpp to loop through each queue and add up the SWBCounts at checkpoint time. The QM_SweepQ function in cmqswp.cpp has been updated so that every time a sweep is aborted, the AbortedSweepCount will be incremented. This TPF MQSeries enhancement will allow the number of SWBs that are currently in use by MQSeries to be displayed on a queue by queue basis as well as by the queue manager. The following three ZMQSC messages have been added to display SWB counts: ZMQSC DISP QL-* SWBCOUNT ZMQSC DISP QL-QNAME STAT ZMQSC DISP QMGR This enhancement will also allow the number of aborted sweeps to be displayed on a queue by queue basis with the following ZMQSC messages: ZMQSC DISP QL-* ABORTSWP ZMQSC DISP QL-QNAME STAT The SWBCOUNT and ABORTSWP parameters have been added with this enhancement so that we can make use of the wildcard functionality on these two new counts.
