AVZ6521H Existing DMF DIV cache at revision level lvl must be re-initialized at current level
Explanation
During initialization the Data Mapping Facility (DMF) found the DIV linear dataset cache dataset (@#$MAPL) contained information formatted for an older/different revision level than the server software now supports. The cache must be discarded and re-loaded in order to switch to the current software support revision level.
User response
DMF cached data maps will be discarded and the DIV dataset re-initialized at the new support level. DMF will reload data maps into the cache, as these are read into storage from the @#$MAPP PDS library.
