Check the reference date of dataset not registered in the control file

Products

• Compress Data Compression for MVS

Issue/Introduction

The dataset report registered in the control file is outputting the latest reference date.

Is it possible to check if a dataset that is not registered in the control file is used by specifying "SUBSYS=(ZSAM,xxxxx)"?

 

Environment

Release : 5.5

Resolution

Compress does not have ways to list which dataset is processed by "SUBSYS=(ZSAM,xxxxx)", but, with RPTCOMP parameter on ZSAM STC, Compress can issue ZSUR072I message to report every OPEN for output to compress.

ex : ZSAM STC
//ZSAMSTC PROC SPARM='SHRKRES,RPTCOMP'

ex : ZSUR072I message
ZSUR072I DDN=SYSUT2 : SUPEREXP USED TO COMPRESS DSN=TSTUSR1.DATA

Customers can trace ZSUR072I message to see which data sets have been processed by Compress.
If ZSUR072I message has a dataset which is not seen in Compress control file, the dataset was processed by ?"SUBSYS=(ZSAM,xxxxx)".
