IC87457: MQSIAPPLYBAROVERRIDE AT 8001 DOESNT MAINTAIN PROPERTY ORDER

WebSphere Message Broker V8.0 - Fix Pack 8.0.0.2

APAR status

• Closed as program error.

Error description

• The command mqsiapplybaroverride can optionally be
  given a properties file containing a list of properties
  to be overriden. At 8.0.0.1 the ordering of individual
  properties within this file is no longer maintained
  which results in unexpected results when the the output
  of an override later in the file depends on a property
  override early in the file.
  
  
  
  For example if the input properties file reads:
  
  
  
  Property1 = temporaryString
  
  Property2 = temporaryString
  
  temporaryString = myString
  
  
  
  The expected output deployment descriptor would contain
  both Property1=myString and Property2=myString.
  
  
  
  Under the current implementation the ordering of the
  overrides is not guaranteed and the output bar file
  may contain one or both of
  Property1=temporaryString and Property2=temporaryString.
  

Local fix

• Apply dependant overrides in multiple stages using more than 1
  invocation of mqsiapplybaroverride.

  PROBLEM SUMMARY:
  The command mqsiapplybaroverride can optionally be
  given a properties file containing a list of properties
  to be overriden. At 8.0.0.1 the ordering of individual
  properties within this file is no longer maintained
  which results in unexpected results when the the output
  of an override later in the file depends on a property
  override early in the file.
  
  
  
  For example if the input properties file reads:
  
  
  
  Property1 = temporaryString
  
  Property2 = temporaryString
  
  temporaryString = myString
  
  
  
  The expected output deployment descriptor would contain
  both Property1=myString and Property2=myString.
  
  
  
  Under the current implementation the ordering of the
  overrides is not guaranteed and the output bar file
  may contain one or both of
  Property1=temporaryString and Property2=temporaryString.
  

Problem conclusion

• WebSphere Message Broker has been modified such that the order
  of overrides is now maintained so that in the scenario above
  both properties contain the value "myString" in the output
  deployment descriptor.
