We recommend that you turn on the CACHE control option. The CACHE control option provides an area of memory for CA Top Secret to place frequently used items from the security file.
Business Value:
The CACHE control option helps reduce I/O and increases system performance. The CACHE control option also allows I/O performed on behalf of one user to benefit another user logging onto a different address space. The IBM Health Checker confirms that you have turned on this control option.
Additional Considerations:
You can determine the recommended value for the CACHE control option by using the TSSFAR utility SFSTATS function. CA Top Secret uses virtual storage above the line within its address space as a method to keep commonly used records from the security file. The CACHE option default is off. Use the TSS MODIFY control option to activate CACHE or specify the CACHE option in the parameter file.
More Information:
For CACHE information, see the Control Options Guide. For SFSTATS information, see the Troubleshooting Guide. For details about how the IBM Health Checker integrates with CA Top Secret, see the Installation Guide.
