JR52278: MODIFYING A WORK BASKET ROLE WHILE UPDATING IS OCCURING MIGHT CAUSE A RUNTIME EXCEPTION AND RISK SLOW PERFORMANCE

8.0.1.2-WS-BPMADV-IFJR52278
Version 8.5 Refresh Pack 7 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• When you update the list of users of a work basket and their
  roles (for example, by pressing the Save button in Business
  Space), an asynchronous update mechanism is triggered in IBM
  Business Process Manager (BPM). Processing the update takes time
  because it is done in slices, depending on the number of tasks
  in the work basket, the number of users assigned to the work
  basket, and the number of roles the users are associated with.
  Processing happens in a logical transaction; for the duration of
  this transaction, the affected work items are blocked and cannot
  be modified by concurrent transactions, such as by process or
  task navigation transactions. If such a concurrent modification
  is attempted, you might see the following a runtime exception:
  
  WorkItem update in progress
  
  The occurrence of the exception causes the transactions to roll
  back, which might eventually lead to a jammed, less responsive
  system.
  

Local fix

Problem summary

• Frequent role updates on work baskets can take time and might
  have to be processed asynchronously (in several slices or
  database transactions). The time required and amount of slices
  depend on the number of tasks in the work basket and the number
  of users and roles assigned to users on the work basket. With
  large work baskets, subsequent work basket role updates can be
  triggered before updates have been processes. As a consequence,
  you receive a ?work item update in progress? exception.
  

Problem conclusion

• A fix is available for IBM BPM V8.0.1.2 that improves how work
  basket role updates are processed.
