Buffer pool parameter vs LRU/MRU
Dear Friends,
I know that in the database buffer cache , the following parameters define the sizes of the caches for buffers :
– Default : DB_CACHE_SIZE
– Keep : DB_KEEP_CACHE_SIZE
– Recycle: DB_RECYCLE_CACHE_SIZE
And also I know LRU and MRU also works in this regards .Now my ques is , when the "keep pool" and " the "buffer pool" is on then LRU and MRU are active ?
Both the above 3 pools and (LRU+MRU) is working together ? I have confusion about that . plz help .. ..
