Issue/Introduction

Prior to SO07293, backup of open VSAM linear data sets completed successfully.
After SO07293, when a backup is attempted on those data sets while they are open, serialization fails and they are not backed up. 
CA Disk backup processing now completes with RC=08 instead of RC=04 and open VSAM linear data sets are no longer backed up.

Resolution

Install PTF SO10594 (OPEN VSAM LDS DATA SETS NOT BACKED UP AFTER PTF SO07293)  
and set the new sysparm DSSTOLNQ to Y to allow the fuzzy backup of these open VSAM LDS data sets.

CIRCUMVENTION:                                                                  
Remove PTF SO07293    

 

Additional Information

Prior to SO07293, backup of open VSAM linear data sets completed successfully. 
After SO07293, when a backup is attempted on those data sets while they are open, serialization fails and they are not backed up.            
We are adding a new sysparm (DSSTOLNQ) to allow the fuzzy backup of these open data sets.                

Take care to copy also the new PARMEDIT member with the definition of the new sysparm.
The PARMEDIT member contains the definition of the new sysparm DSSTOLNQ.

Sysparm DSSTOLNQ:
The default value is N, which causes the DSS data mover to bypass any data sets which cannot be successfully serialized. 
If set to Y, the TOLERATE(ENQFAILURE) command parm will be included in the DFSMSdss DUMP command stream.
