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

• LRU queues
• Limiting the number of pages added to the MLRU queues

LRU_MAX_DIRTY specifies the percentage of modified pages in the LRU queues at which the queue is cleaned.

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

% onutil
> SET LRU_MAX_DIRTY "4.5";
