Abstract

OSP-DB-MSGMCH3601-F/QSQRUND PREVENT RECURSIVE LOOP DURING ENDJOB

Error Description

Prevent recursive looping between QSQFCI exception handler path
and QSQSETTXT.  QSQFCI calls ?SQSETTXT and QSQSETTXT calls      
?SQFCONDI.  Since we are in job termination, some MCH3601's are
expected and should be ignored, but it shouldn't result in      
looping.                                                        
                                                               
Fix here is to first check SQLCOND@ is NULL and if so, do not  
process further.  That will prevent some MCH3601's.  The second
change is to create a new STATIC ABNORMAL bit in QSQFCI and set
it once we enter the exception handler path so that we do not  
recursively call between QSQSETTXT and QSQFCI under MCH3601    
exceptions.
