Error description

  • BPMMigrateInstances causing failures across nodes in a clustered
    environment in 8.5.5.
    
    You may notice hung thread warnings which include this method:
    at com.lombardisoftware.server.processmonitor.jmx.
    InstanceMigrationManager.distributeMigrationLoad
    (InstanceMigrationManager.java:106)
    
    SOAP timeout exceptions may also occur when using this command.

Problem summary

  • ERROR DESCRIPTION:
    When you run the BPMMigrateInstances wsadmin command in
    V8.5.5.0, you experience  SOAP connection timeout issues in
    clustered (multi-node) environments.
    
    PRODUCTS AFFECTED
    IBM Business Process Manager (BPM) Advanced
    IBM BPM Standard
    IBM BPM Express
    
    LOCAL FIX -
    None
    
    
    PROBLEM SUMMARY
    SOAP connection timeout issues occur because migrating process
    instances by using the BPMMigrateInstances wsadmin command in
    V8.5.5.0 wrongly invokes instance migration on other nodes in
    the cluster.
    

Problem conclusion

  • An interim fix is available on IBM BPM V8.5.5.0 that ensures the
     BPMMigrateInstances command migrates instances  only on the
    node where the command was run.
