Issue/Introduction

IDMS messages like DC027007 cause an SVC dump to be generated. For test CVs this dump is not required.

How to suppress the SVC dump?

Environment

Release: 19.0

Cause

If SYSTEM SNAPS are on in the SYSGEN which is the default, an SVC dump will be generated in z/OS.

To check the status of the SNAPs issue DCMT command:

DCMT DISPLAY SNAP

           *** DISPLAY SNAP REQUEST ***
      SYSTEM SNAP STATUS IS ON (ENABLED)
     SYSTEM SNAP PHOTO STATUS IS ON (ENABLED)
     TASK SNAP STATUS IS OFF (DISABLED)
     TASK SNAP PHOTO STATUS IS OFF (DISABLED)
     TASK SNAP TRACE STATUS IS ON (ENABLED)
     TASK SNAP TRACE LIMIT  9999

Resolution

Turn off system snaps and system photo with these DCMT commands:

DCMT VARY SNAP SYSTEM OFF
DCMT VARY SNAP SYSTEM NOPHOTO

This will only last until the CV is shutdown.

To make this permanent, the option must be changed in the SYSTEM statement of the SYSGEN and system regenerated:

MOD SYS nnn
SNAP SYSTEM OFF
SNAP SYSTEM PHOTO OFF.
GEN.
