Issue/Introduction

What are the roles and function of the Common Components and Services for z/OS (CCS) started task CAVARSRV?. 

In documentation there is the following: 

The Common Variable Service  supports Broadcom  products that maintain system and sysplex scope status variables.

The CAVARSRV address space is required to support sysplex scope variables. Every active CAVARSRV member in a sysplex hosts the exact same copy of sysplex variables.

Which are the sysplex scope variables?. 

Resolution

The CAVARSRV started task supports Broadcom products that maintain system and sysplex scope status variables, i.e. by itself it does nothing but it exists for individual products to utilize. The CAVARSRV started task can maintain variables for a local system or synchronize variables across a sysplex, as defined by the product.
 
OPS/MVS is the only product that uses this service currently, but it is possible that other products can adopt it in the future. If your site is a user of OPS/MVS, the OPS/MVS documentation should describe how it leverages CAVARSRV functionality within the product.
