CKM120W4W ** Because GRSRNL=EXCLUDE is in effect and MIMQUERY is not available, MERGECAT cannot check for data sets which are in use only on another system. Catalog errors or corruption of VSAM data sets can occur if they are in use on another system.

Explanation

This system is running with GRSRNL=EXCLUDE. Normally this is used when a product other than GRS (such as MIM/MII) is being used to manage cross-system enqueues, in which case MERGECAT is unable to see SYSDSN enqueues on other systems unless MIMQUERY is active. Since MIMQUERY is not active, MERGECAT NOMOVE-IN-USE cannot detect data sets which are in use only on other systems and consequently MERGECAT may move catalog entries for data sets which are in use, possibly resulting in catalog errors and corruption of VSAM data sets.
