AVZ6522H Existing DMF DIV cache being discarded due to incomplete update at last LDS expansion

Edit online

Explanation

During initialization the Data Mapping Facility (DMF) found the DIV linear dataset cache dataset (@#$MAPL) could not be placed online because a DIV expansion operation failed to complete properly during the prior start-up. The cache must be discarded and re-loaded in order to remove any incompletely allocated logical window areas.

User response

DMF cached data maps will be discarded and the DIV dataset re-initialized. DMF will reload data maps into the cache as these are read into storage from the @#$MAPP PDS library.
