Issue/Introduction

When using CA Datacom Multi-User (MUF) startup option SYSOUT, the PXX snaps, diagnostics, and traces are redirected to the sysout class instead of to the physical PXX data set.
 

How to test that Datacom SYSOUT startup option is sending output to a SYSOUT class instead of to the physical PXX data set?




 

Environment

z/OS

Resolution

One way to test that output is being written to a SYSOUT class is to issue a SNAP console command to the Datacom Multi-User (MUF).

SNAP will force the Master list to be written to PXXMLnn

/f mufstc,SNAP 

Then notice the content of the SYSOUT class identified as PXXMLnn contains the Master List. 

Then to clear the CLRMLnn sysout:

/f mufstc,CLRML   

The SNAP can also be issued using batch DBUTLTY command:

COMM OPTION=SNAP

The clear can also be issued using batch DBUTLTY command:

COMM OPTION=CLRML
