Issue/Introduction

 What is the maximum specification for the CACHE control option?

 

 

 

Resolution

Top Secret never allows CACHE allocated to exceed the storage it needs to operate. Assure that there is adequate region size allocated for the TSS task to accommodate the cache request. The recommended value for the CACHE control option can be determined using the TSSFAR utility SFSTATS function. 

When using large file sizes, the requested cache size might not be met due to operating system constraints. If the recommended cache size is not being met, an increase in the region size for CA Top Secret is recommended. Consult your system programmer regarding the maximum address space size set within your system.
