MH06: WebSphere MQ - Trace Tools
This SupportPac provides simple command line tools (mqtrcfrmt, mqoptions, and mqapitrcstats) to aid in using MQ traces.
The tools provided in this SupportPac aid in formatting MQ data structures and fields into a more human-readable format. The mqtrcfrmt tool takes a distributed MQ trace as input and writes out as output the trace file contents but with MQ data structures and fields (i.e. msgdesc, objdesc, reason code) expanded into human-readable lines that show the individual data fields and also what constants the numerical values represent.
The mqoptions tools take the numerical value of an MQ option field (i.e. GMO) and display the MQ constant values (i.e. MQGMO_WAIT) that the numerical value represents.
The mqapitrcstats tool produces a performance statistics report from the trace.
Aid for reading MQ traces.
Aid for converting MQ options numerical values to their constant values.
Aid for getting performance statistics reports from distributed trace.
Skill Level Required:
This SupportPac requires a working knowledge of WebSphere MQ administration.
New in this Release:
- Supports MQ 9.1.
- mqtrcfrmt is now also provided as a Java jar with source code included.
- mqtrcfrmt Java version provides a global feature to copy all messages in a trace to a set of files.
- MQFile2Msg provides a feature to read a set of trace files and put them onto a queue.
- mqtrcfrmt now reports when unknown constants are encountered and also supports 819 for message parsing.
- mqtrcfrmt and mqapitrcstats now support large files (>=2GB) for the 32 bit unix executables.
- Support for IBM MQ v9.
- mqtrcfrmt has a new message search option to allow you to search for hex and character strings in the message data of a distributed or application activity trace.
- mqsc_qmgrs - A new Unix bash script that allows you to execute runmqsc client mode commands against a group of queue managers and then return the individual results in a single line format for searching capabilities.
Message parsing in mqtrcfrmt. Message parsing provides the ability to do byte analysis on a message in a strmqtrc or activity trace, and find out information such as how much of the message is ASCII, the offset location and numbers of multi-byte 1208 characters, the offset location and numbers of surrogate pairs, the offset locations and numbers of invalid bytes if the message was marked as 1208 or 1200, and so on. This tool could be used to do investigations such as "does this message contain surrogate pairs?" (which is not supported by MQ) and "where are the surrogate pairs located in the message?", "has the message been incorrectly marked as 819 when it has a 1208 make up?", "does the message contain non-ASCII bytes that could potentially cause a data conversion issue if the application is ported between servers with a different default CCSID for the queue manager?", and so on.
Msg2File in mqtrcfrmt. This provides the ability to put a special tag above a message in a strmqtrc or activity trace output, and then have the mqtrcfrmt write the contents of the message to a file. This file could then be used to PUT the message back onto a queue. As a convenience, a java program called MQFile2Msg is provided to PUT the file onto a queue.
amqsactz activity trace tool. amqsact is an IBM supplied sample for formatting activity trace records. amqsactz takes the amqsact sample and provides some usability enhancements for working with activity trace data. The amqsactz source and a sample Linux executable is provided in the SupportPac.
- Mqoptions executable has been changed to a Java MQOptions.class that is more portable and robust when working with deciphering MQ options.
- Pub/Sub support for distributed traces.
- Pub/Sub and Callback support for z/OS traces.
- Report option added to mqoptions.
- Manual in PDF format.
