Issue:
When the BMP option is used to collapse BMP message-driven transaction
records, a S0C4 ABEND might occur while running LDE as an exit in the 
IMS Archiver. The same problem can occur while processing raw IMS log 
data with a standalone LDE job, or with a DAY060/INCR060 step.        
                                                                      
This problem does not affect customers who process data generated by  
BMC Mainview for IMS.                          

SYMPTOMS                                                              
The IMS Archive using the LDE exit or the standalone LDE job or the   
DAY060/INCR060 step fail with a S0C4 ABEND and error messages similar 
to the following appears in the JESMSGLG output DD:

IMPACT                                                                
The IMS log records cannot be processed.                                                     
Resolution:
IMS6709 - CORRECT S0C4 ABEND IN BMP TRANSACTION PROCESSING                                                  
                                                       
Additional Information:
CIRCUMVENTION                                                       
If you run LDE as an EXIT to the IMS Archiver, change the BMP option
in LDEPARM to NOBMP.                                                
                                                                    
If you input IMSLOG data directly into DAY060, change the BMP option
in IMSOPS to NOBMP and run prefix.MICS.CNTL(IMSPGEN).               

Note that this circumvention bypasses the BMP collapse feature, 
potentially increasing the number of observations written to the
MICS database files.
