Error description

  • ERROR DESCRIPTION -
    Migrating process instances that contain unwired subprocesses or
    linked processes that are not ad hoc might  return an inaccurate
    warning message in the SysOut.log file: ?detected a flowobjects
    loop of length=xxxx". Additionally, you might notice performance
    degradation.

Problem summary

  • When instance are being migrated, you might see a similar
    warning message appear in the SysOut.log file:
    
    [11/21/14 11:20:46:392 UTC] 000001d9 wle_migration W
    com.lombardisoftware.bpd.runtime.
    engine.cases.MigrateBPDAdhocActivityInstances
    addAdhocActivitiesFromDiagram
    Detected a Flowobjects Loop of length=1020.
    
    or
    
    [2/23/15 12:05:52:478 CST] 00018147 wle_migration W
    com.lombardisoftware.bpd.runtime.
    engine.cases.MigrateBPDAdhocActivityInstances
    addAdhocActivitiesFromDiagram Detected a Flowobjects Loop of
    length=1. FlowObject Id's in this Loop
    are=[BPDObjectIdImpl(...)] .   Current FlowObject is =...,
    id=BPDObjectIdImpl(...) . Stopping the precondition cache
    computation for this loop.
    
    This warning is emitted when processes are self-referential or
    recursive, meaning that a linked process points to the current
    process definition. However, for unwired subprocesses and linked
    processes that do not have ad hoc activity support enabled (?The
    activity runs even though it does not have an inbound flow? is
    set to false), the activity cannot produce ad hoc activity
    instances, so updating the precondition cache is unnecessary and
    detrimental from a performance perspective.
    

Problem conclusion

  • A fix is available for IBM BPM V8.5.5.0 that excludes unwired
    non-ad hoc event subprocesses, subprocesses, and linked
    processes when updating the precondition cache during instance
    migration.
