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.
