IC86992: WMB V7.0 : ENVIRONMENT VARIABLE TO HONOUR CONTENT VALIDATION WHILE MRM-TDS PARSING

WebSphere Message Broker V8.0 - Fix Pack 8.0.0.2

APAR status

• Closed as program error.

Error description

• From V7.0.0.1 onwards, WMB allows searching of open defined
  global elements when the search for existing children has been
  exhausted and the separation type allows. Which means even when
  the content validation is closed, you can have open defined
  elements in the tree when the message is parsed. This can
  produce a wrong result compared to previous versions, for any
  model, which has many global elements and tagged structures,
  which allow open content. The behavior cannot be reverted,
  as it will break any model that depends on searching of open
  defined global elements when the search for existing children
  has been exhausted. Under this APAR we will introduce an
  environment variable MQSI_MRM_TDS_HONOUR_CONTENT_TYPE to solve
  such issues. When this environment variable is set the MRM-TDS
  parsing will not parse and add open contents unless the Content
  Validation is Open/Open Defined.

  PROBLEM SUMMARY:
  From V7.0.0.1 onwards, WebSphere Message Broker allows searching
  of open defined global elements when the search for existing
  children has been exhausted and the separation type allows.
  Which means even when the content validation is closed, you
  can have open defined elements (which are not the defined
  children) in the tree when the message is parsed. This can
  produce a wrong result compared to previous versions, for any
  model, which has many global elements and tagged structures,
  which allow open content. The behavior cannot be reverted, as it
  will break any model that depends on searching of open defined
  global elements when the search for existing children has been
  exhausted.
  

Problem conclusion

• This APAR introduces an environment variable
  MQSI_MRM_TDS_HONOUR_CONTENT_TYPE to address this problem. When
  this environment variable is set (to any value) the MRM-TDS
  parsing will not parse and add open content, unless the
  Content Validation is Open/Open Defined.
