JR57164: PERFORMANCE IS SLOW DURING RUN TIME AND WHILE MANAGING EPV VALUES IN THE PROCESS ADMIN CONSOLE

APAR status

  • Closed as program error.

Error description

  • In the Process Admin Console, you can define multiple values for
    an exposed process variable (EPV) in a particular snapshot and
    can synchronize EPV values from one snapshot to another. During
    synchronization, all EPV values of the source snapshot are
    copied to the target snapshot, which might result in a large
    amount of EPV values over time. Numerous EPV values negatively
    affects performance during run time and while managing EPV
    values in the Process Admin Console.
    
    PRODUCTS AFFECTED
    IBM Business Process Manager (BPM) Advanced
    IBM BPM Standard
    IBM BPM Express
    

Local fix

  • EPV values of a snapshot can be deleted only when the snapshot
    is deleted. You must create a snapshot by using the latest EPV
    values of the previous snapshot as defaults. Then you must
    delete the older snapshots. In the future, you must use EPV
    synchronization carefully and only when there are fewer EPV
    values in the source snapshot.
    

Problem summary

  • Because only EPV values with an effective_on date set to the
    future can be deleted in the Process Admin Console, all
    historical EPV values remain in the database. Therefore, the
    number of EPV values increases over time. This increase depends
    on the number of snapshots, the number of  EPV values in a
    snapshot, and the number of synchronizations between snapshots.
    This quantity decreases  performance during run time as well as
    the performance in the Process Admin Console while you manage
    EPVs.
    

Problem conclusion

  • A fix will be included in IBM BPM V8.5.7 cumulative fix 2017.03
    that provides a command to clean up the EPV values' history.
