The GET_LIB_ENQ keyword in the CSVLLAxx member allows you to prevent LLA from obtaining an exclusive enqueue on the libraries it manages. If you specify GET_LIB_ENQ (NO), your installation's jobs can update, move, or delete LLA-managed libraries while other users are accessing the libraries. GET_LIB_ENQ (NO) is generally not recommended, however, because of the risks it poses to data set integrity.
