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.

  LOCAL FIX -
  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.
  

Temporary fix
