BUFFER_POOL_RECYCLE

Parameter type:	String
Syntax:	BUFFER_POOL_RECYCLE = integer | (BUFFERS: integer [, LRU_LATCHES: integer] ) where integer is the number of buffers and, optionally, the number of LRU latches.
Parameter class:	Static
Default value:	None
BUFFER_POOL_RECYCLE lets you limit the size of objects in the buffer cache by setting aside a portion of the total number of buffers (the value of the DB_BLOCK_BUFFERS parameter) as a RECYCLE buffer pool. You can also allocate to the RECYCLE buffer pool a specified portion of the total number of LRU latches (the value of the DB_BLOCK_LRU_LATCHES parameter). The string value can take one of two forms. You can simply specify a buffer count: BUFFER_POOL_RECYCLE = 5 or you can specify a combination of buffers and LRU latches. Specifying LRU latches is optional: BUFFER_POOL_RECYCLE = (BUFFERS: 50 [, LRU_LATCHES:1] )
This parameter is most useful in combination with BUFFER_POOL_KEEP. See Also: Oracle8i Designing and Tuning for Performance for information on setting these parameters and on using multiple buffer pools.
