Object documentation LRUS (Informix)  Locate the document in its SAP Library structure

Definition

The LRUS parameter from the Informix ONCONFIG file specifies the number of least recently used (LRU) queues in the shared memory buffer pool. Informix divides its buffers into LRU queues to minimize contention when processes look for free buffers. The number of these queues is set using this parameter.

Use

For up-to-date recommendations, see SAP Note 41360.

To control how frequently the shared memory buffers are flushed to disk, tune the value of LRUS in combination with LRU_MIN_DIRTY and LRU_MAX_DIRTY.
