Situation Description

The Low Hit% threshold has been reached.

 

Suggested Actions

A Hit% < 20% probably means that the overhead of managing the cache costs more than just doing the I/O to DASD. For CDSC caching, consider increasing the amount of virtual storage allowed for catalog caching, or reverting to ISC caching, or not caching at all. Newly opened catalogs and master catalogs can have low hit%.
