Error description
It is currently not possible to correlate CICS TYPE 110 SMF records with WebSphere MQ Type 116 SMF records. It is however possible to correlate CICS Type 110 SMF records with DB2 Type 101 SMF records, and use the CICS Performance Analyser to produce reports for CICS/DB2 transactions. CICS sets the 27 byte network UOWID and extracts from this a 22 byte correlation token which it passes to DB2 and which DB2 in turn sets in DB2 Type 101 SMF records. CICS also passes the 27 byte network UOWID to WebSphere MQ so that WebSphere MQ can extract from it the 22 byte correlation token and set it in WebSphere MQ Type 116 SMF records. The QWHCTOKN field already exists in the Type 116 SMF records however, WebSphere MQ currently does not store and set this correlation token field. This APAR is being raised so that WebSphere MQ can set this correlation token.

Problem summary
**************************************************************** * USERS AFFECTED: All users of Websphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: WebSphere MQ Type 116 SMF records * * cannot be correlated with CICS Type 110 * * SMF records. * **************************************************************** * RECOMMENDATION: * **************************************************************** Type 116 SMF records are used for processing type accounting records. As these records do not correlate with CICS type 110 SMF records, this restricts the ability to correlate this accounting data for CICS/WebSphere MQ transactions. For example this results in CICS Performance Analyzer not being able to adequately generate reports for these transactions. This is due to the accounting token in the type 116 SMF records (QWHCTOKN), being set correctly, as to allow these to be correlated with the CICS Type 110 SMF records.
Problem conclusion
Temporary fix
Comments
The accounting token, QWHCTOKN, in the WebSphere MQ SMF records has been altered, to be set to the correct value, allowing correlation. --------------------Info Center Changes------------------------- Common WebSphere MQ SMF header At Location: WebSphere MQ > Monitoring and performance > Monitoring performance and resource usage on z/OS > Interpreting WebSphere MQ accounting data Page: http://publib.boulder.ibm.com/infocenter/wmqv7/v7r1/topic /com.ibm.mq.doc/zs12000_.htm Change: Below the paragraph starting "The QWHC data gives you information" add the following : "The QWHC section is completed only for subtype 0 records. The equivalent information is present in the thread identification record for subtype 1 and 2 records." --------------------------------------------------------------- Add a new page with title: "Combining CICS and WebSphere MQ performance data" At Location: WebSphere MQ > Monitoring and performance > Monitoring and performance > Monitoring performance and resource usage on z/OS > Interpreting WebSphere MQ accounting data Contents: The common WebSphere MQ SMF header type accounting record section, QWHCTOKN, is used to correlate CICS type 110 SMF records with WebSphere MQ type 116 SMF records. CICS generates an LU6.2 unit-of-work token, for each CICS task. The token is used to generate an accounting token which is written to QWHCTOKN in the correlation header of subtype zero records. Details are also written to the WTIDACCT section in subtype 1 and 2 records. The accounting token enables correlation between CICS and WebSphere MQ performance data for a transaction.
