Abstract:  batch jobs are incorrectly submitted in a synchronous fashion

Description/symptom of problem:  
PI16920 resolves the following problem:

ERROR DESCRIPTION:                                              
When WebSphere Application Server Batch Jobs are submitted for  
processing, they run synchronously. This can lead to slow       
downs and delays in job processing. The correct behavior        
should be asynchronous job dispatch.                            

LOCAL FIX:                                                      

PROBLEM SUMMARY

USERS AFFECTED:
 All users of IBM WebSphere Application
Server V8.5 Compute Grid batch
functionality

PROBLEM DESCRIPTION:
Jobs submitted via the scheduler are
incorrectly dispatched in a
synchronous fashion.

RECOMMENDATION:
None

Batch jobs submitted via the scheduler should be dispatched in
an asynchronous fashion.

PROBLEM CONCLUSION:                                             
The code has been corrected to eliminate the synchronous        
dispatch and allow jobs to be dispatched asynchronously.        
.
