IC96519: WMQ FTE: ENABLING TRACE FOR THE WMQ CLASSES FOR JAVA PACKAGES RESULTS IN A LARGE AMOUNT OF DATA BEING WRITTEN TO TRACE FILES

WebSphere MQ V7.5 Fix Pack 7.5.0.3
WebSphere MQ File Transfer Edition V7.0 Fix Pack 7.0.4.4

APAR status

• Closed as program error.

Error description

• In WebSphere MQ File Transfer Edition if trace is turned on
  with a trace string that includes the WebSphere MQ classes
  for Java client (for example "=all") then the generated trace
  files contain a large amount of data. This is due to all the
  bytes of
  each message being sent to the queue manager being dumped to
  the trace files. For a system with many file transfers or
  large file transfers this can lead to trace files that are
  wrapped and only
  cover a very short period of time. This can hinder problem
  diagnostic activities.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of WebSphere MQ File Transfer Edition
  7.0.4 and WebSphere MQ Managed File Transfer 7.5
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  When trace was turned on that included the WebSphere MQ
  classes for Java package, large trace files would be produced as
  all data for each WebSphere MQ message would be output to the
  trace files. For an agent with many transfers or large transfers
  this would hinder the diagnosis of problems as the trace file
  would quickly wrap and key information was overwritten.
  

Problem conclusion

• This APAR introduces a new agent property called
  traceMaxBytes. By default this property is set to 4096,
  meaning that the trace will contain up to the first 4096 bytes
  of each administrative message sent or received by the agent.
  This default property value can be overridden by defining an
  alternate value in the agent.properties file. If this property
  is set to -1 then the output will be unlimited.
