Mainframe Enablers TimeFinder SnapVX and zDP 8.5 Product Guide

This parameter improves job completion times for jobs with high device counts.

When set or defaulted to Yes, information for every device in the storage system is retrieved in one system call with a range of all devices in the storage system, instead of issuing individual system calls for each. This reduces the I/O latency of repeatedly querying the storage system.

Set CACHE_FULL_SYM(YES) for jobs with approximately 500 or more devices.

The CACHE_FULL_SYM parameter can be specified on the GLOBAL command. It has a matching site option, &CACHESYM.
