APAR status

  • Closed as fixed if next.

Error description

  • When you use Process Admin Console to migrate numerous inflight
    process instances, the web browser might crash or hang because
    of memory issues. The server returns very large blocks of
    instance data to the client browser.
    

Local fix

  • Use the BPMMigrateInstances command when migrating large volumes
    of instances instead of the console.

    None.
    

Problem conclusion

  • A fix is currently targeted for inclusion in an upcoming
    cumulative fix on IBM BPM V8.5.7.0 that allows you to specify a
    setting in the 100Custom.xml file to limit the number of
    instances to be migrate at once. The following new setting sets
    the number of instances to be migrated each time to 1000:
    
        <server>
             <instance-migration merge="mergeChildren">
                <migrate-instances-count
    merge="replace">1000</migrate-instances-count>
             </instance-migration>
        </server>
    
    If this settings is specified, it is applied to instance
    migration for both the Process Admin Console instance and the
    BPMMigrateInstances wsadmin command. After each round of
    migration, check Process Inspector to determine whether there
    are remaining instances still pending to migrate and then
    perform another round of migration for the remaining instances.
