Abstract:  WS-AtomicTransaction participant recovery after a server crash may never complete

Description/symptom of problem:  
PI59123 resolves the following problem:

ERROR DESCRIPTION:                                              
A subordinate participant in a global transaction               
distributed via the WS-AtomicTransaction protocol may fail      
to recover. This could happen in the event that the server      
acting as the transaction coordinator crashes while the         
subordinate transaction on the participant server is            
in-doubt.                                                       

LOCAL FIX:
