PM54616: EXPERIENCING POOR PERFORMANCE OF RMI SERVER DURING HIGH VOLUME WITH MULTIPLE USERS

APAR status

• Closed as program error.

Error description

• RMI server experiences poor performance where new map
  executions are being blocked during high volume with multiple
  users are connected.
  

Local fix

• WTXCQ - WTX00039569
  JX / JX
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender RMI Server users that are
  employing the multi-user mode will notice a dramatic improvement
  in concurrency and overall map throughput, particularly during
  heavy peak loads
  
  Problem Description:
  The RMI Server is not executing efficiently during peak load
  activity.
  
  Platforms Affected:
  ALL
  

Problem conclusion

• The RMI Server's multi-process mode has been optimized so that
  greater map concurrency can be achieved during peak loads.
  Before this fix, the old multi-process monitoring logic could
  easily block start up and execution of new maps.  Based on local
  stress testing with 25 simultaneously executing RMI Clients, the
  new fixes have resulted in a 100% RMI Server map throughput
  performance improvement.
