OPS/MVS - SYSPLEX variable volatility when performing time change

Products

• OPS/MVS Event Management & Automation

Issue/Introduction

During the weekend a time change is planned and all lpars will be shutdown in your sysplex at one point.
The question is: what is the ideal process(es) to prevent the sysplex level variables and their values from being destroyed?

Environment

All releases

Component : OPS/MVS

Cause

Time change with full SYSPLEX outage with Sysplex Variables in use

Resolution

The best method would be to leave at least one LPAR with OPS/MVS active, while the other LPARs are shut down.
Then once the OPS/MVS started task is active on one of those systems, the final system may be taken down.
Leaving at least one system active at all times will preserve the Sysplex Variables that reside in the coupling facility.
However, if all systems must come down at the same time, then implement the SYSPLEX VARIABLE BACKUP as documented in the Sysplex Variable Backup section of the Installing Guide under the Configuring and Installing Optional Components.
