IT16718: MQSIMIGRATECOMPONENTS CAN LOSE FLOW LEVEL ATTRIBUTES IF A MESSAGE FLOW USES DEPLOYABLE SUBFLOWS

APAR status

• Closed as program error.

Error description

• The mqsimigratecomponents command can lose message flow level
  attributes, such as additional instances, deploy information,
  monitoring settings etc, if a message flow uses deployable
  subflows.
  

Local fix

• There is no workaround to this problem. The APAR fix will need
  to be applied and the same broker be back migrated to the
  previous release and then forward migrated to V10.0 again.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10.0 using the
  mqsimigratecomponents command to migrate previous product
  version message flows that contain references to deployable
  subflows.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The mqsimigratecomponents command is used to migrate previous
  versions of the product to v10.0. As part of this processing,
  message flows are migrated from the internal configuration
  tables to the file system. If a message flow references
  deployable subflows (.subflow files) then there will be two
  representations of the message flow:
  1) The original (parent) message flow that still contains the
  subflow nodes.
  2) An inlined message flow where all of the subflow nodes have
  been resolved.
  In IBM Integration Bus v10.0 option 2 is no longer needed.  As
  such the mqsimigratecomponents command will merge the flow level
  attributes.
  
  A defect exists such that this process ends too early resulting
  in flow level attributes such as additional instances, deploy
  information, monitoring settings etc being lost.  Which settings
  are lost is dependent on what order they were serialised in the
  flow XML.
  
  This could be visible to the user when they try to view the flow
  level attributes using mqsilist, mqsireportproperties or through
  the webui.
  

Problem conclusion

• The product has been corrected to copy all flow level attributes
  when merging a parent flow and an inlined message flow on
  migration.
