Resolution

This CCI Health Check was introduced with PTF LU12388 (part of level set Set 15.0.08).

The purpose of this healthcheck is to make sure that CCIxxxGW does not adversely impact performance of a Broadcom MF product that is using this CCI service to process activity.

So there is a comparison between any MF product using CCI and is running with WLM service class SYSSTC, and the CCIxxxGW task. If it finds that CCIxxxGW is not also running SYSSTC, the health check will be triggered.

The related Health Check can be viewed using the Health Checker panels in SDSF or SYSVIEW.

The CK command can be used in SYSVIEW to locate and select the CCS_CCI_WLM_VERIFY health check. 

Selecting the CCS_CCI_WLM_VERIFY health check, the details of which CCI address space is mis configured will be shown.
