IT04579: UNNECESSARY GRAPHICAL DATA MAP PROCESSING ON RESTART

APAR status

• Closed as program error.

Error description

• Unnecessary processing of graphical data maps may occur on
  restart if
  the maps are stored in a named folder and either (for WebSphere
  Message
  Broker v8.0.0.4 or later) the MQSI_PREPARE_MAPS_ON_DEPLOY
  environment
  variable is set to TRUE or (for IBM Integration Bus v9.0.0.1 or
  later)
  the broker function level is set to 9.0.0.1 or later.
  
  This applies to restart of any of the following items:
  
  For WebSphere MessageBroker:
  - Message Broker
  - Execution group
  - Application
  - Message flow
  
  For IBM Integration Bus:
  - Integration Bus
  - Integration Server
  - Application
  - Message flow .
  
  When, in WebSphere Message Broker v8.0.0.4 or later, the
  MQSI_PREPARE_MAPS_ON_DEPLOY environment variable is set to TRUE,
  or, in IBM Integration Bus v9.0.0.1 or later, the function level
  is set
  to 9.0.0.1 or later, the behavior on restart for graphical data
  maps
  used in message flow Mapping nodes is that the deployed map
  references
  are validated, and if a persisted prepared map is available,
  then it
  can be used.
  
  However, if the maps are stored in a named folder, for example
  in a
  folder named "gen", then the restart time is extended by the
  time
  taken for full map preparation of the maps in the named folder.
  

Local fix

• Move the affected maps from the named folder to the project
  root folder.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of WebSphere Message Broker V8.0 or IBM Integration
  Bus V9.0 where maps for mapping nodes are prepared on
  deployment.
  
  
  Platforms affected:
  z/OS, MultiPlatform

  PROBLEM DESCRIPTION:
  Unnecessary processing of graphical data maps may occur on
  restart if
  the maps are stored in a named folder and either (for WebSphere
  Message
  Broker v8.0.0.4 or later) the MQSI_PREPARE_MAPS_ON_DEPLOY
  environment
  variable is set to TRUE or (for IBM Integration Bus v9.0.0.1 or
  later)
  the broker function level is set to 9.0.0.1 or later.
  
  This applies to restart of any of the following items:
  
  For WebSphere Message Broker:
  - Message Broker
  - Execution group
  - Application
  - Message flow
  
  For IBM Integration Bus:
  - Integration Bus
  - Integration Server
  - Application
  - Message flow .
  
  When, in WebSphere Message Broker v8.0.0.4 or later, the
  MQSI_PREPARE_MAPS_ON_DEPLOY environment variable is set to TRUE,
  or, in IBM Integration Bus v9.0.0.1 or later, the function level
  is set
  to 9.0.0.1 or later, the behavior of graphical data map is
  altered and the
  maps are prepared for execution on deployment instead of when
  the
  first message flows through the node.
  
  With this option, the behavior for graphical data maps on
  restart is
  also changed. On restart, the deployed map references
  are validated, and if a persisted prepared map is available,
  then it
  can be used.
  
  However, if the maps are stored in a named folder, for example
  in a
  folder named "gen", then the restart time is extended by the
  time
  taken for full map preparation of the maps in the named folder.
  
  
  There are a number of resource name changes between WebSphere
  Message Broker and IBM Integration Bus Version 9.0. For details

Problem conclusion

• The product no longer performs unnecessary map preparation on
  restart when maps are stored in a named folder.
