Issue/Introduction

Speed up IEFBR14 with DISP=(?????,DELETE) processing by uncataloging an archived data set instead of restoring it by DMSAR and then uncataloging it.

Resolution

If you do the following per the IBM instructions CA Disk will not start a DMSAR for a data set cataloged to ARCIVE when using IEFBR14 with DISP=(?????,DELETE), instead the data set will be uncataloged from ARCIVE:

1. Specify IEFBR14_DELMIGDS(NORECALL) in ALLOCxx of SYS1.PARMLIB
   
   OR
   
   
2. Issue SETALLOC SYSTEM,IEFBR14_DELMIGDS=NORECALL from SDSF SYSLOG PANNEL 
   
   This will speedjob processing and save CPU cycles.

Note: The DSNINDEX record will continue to be processed by normal IXMAINT processing rules.
