The following topics in the shared-memory chapter of the IBM Informix: Administrator's Guide:

• LRU queues
• When MLRU cleaning ends

LRU_MIN_DIRTY specifies the percentage of modified pages in the LRU queues at which page cleaning is no longer mandatory. Page cleaners might continue cleaning beyond this point under some circumstances.

To modify the LRU_MIN_DIRTY parameter dynamically, use the onutil SET command. Example:

% onutil
1> SET LRU_MIN_DIRTY "1.5";
