Description
The limit on the number of significant internal operations that a user can execute without swapping (giving up the processor to another user)
SQLLPLIM swaps a query when it reaches SQLLPLIM internal operations, which includes indexed finds, fetching from files and intermediate result tables, and writing to files and intermediate result tables. The SQLLPLIM counter returns to zero when the query regains control of the processor.
SQLLPLIM is an integer value whose minimum is 0, maximum is 32767, and default is 200. Setting SQLLPLIM too low can cause excessive swapping for users in a busy Online.
