Error description

  • When the group member cache of nested groups is being handled,
    unnecessary lookups occur in LDAP, which causes performance
    issues trying to resolve all users of a participant group by
    using TWParticipantGroup.allUsersホレ when the participant group
    contains nested groups defined in IBM Business Process Manager
    (BPM).
    

Local fix

Problem summary

  • If a group in the IBM BPM group member cache must be refreshed
    when one of the subgroups has been refreshed, superfluous checks
    occur.
    

Problem conclusion

  • A fix is available for IBM BPM that optimizes the refresh
    implementation by preventing unnecessary checks.
