Issue/Introduction

All Disk FDS/FDB Unload files (SEQFILES) created either:

- for FDSs using "PGM=ADSMI002,PARM=ADSDM177"

or

- for FDBs using "PGM=ADSMI002,PARM=ADSDC177"

have no Last Reference date: 

Referenced date . . : ***None***

Not having a Reference date in an SMS managed environment does affect the Archive process of these data sets because  there will be no Archive without a Ref-date.

How is it possible to set it for FDS/FDB Unload files.

Environment

Release:  All
Component: Disk Backup and Restore

Cause

The Last Use/Reference date is not set for the data sets created by FDS/FDB UNLOAD because, as per default setting of the DISK SVC, the program exclusion table (ADSOPPGM) is initialized to bypass DSCB updating for any program starting with ADSMI. This is described in the Disk Installation Guide, chapter "The CA Disk SVC".

Resolution

It is always possible to set the Last Reference Date, using an additional step that just opens the SEQFILES output data set like an IDCAMS PRINT COUNT(1): 

//PRINT EXEC PGM=IDCAMS              
//SYSPRINT DD SYSOUT=*               
//INDD DD DISP=SHR,DSN=dsname        
//SYSIN DD *                         
PRINT INFILE(INDD) CHARACTER COUNT(1)
/*
