RE: Slow database, too MANY buffers???

>From your e-mail, I get the impression that there is a 687 Mb SGA on a box
with 256 Mb. If that is the case, then the majority of the instance is sitting out on a swap file ... on a hard drive ... not in memory. For what it's worth, 687 Mb SGA is not **HUGE** (actually, it's rather small these days). But 256 Mb of memory is **TINY**. All this ASS-U-ME-s that I have interpreted your post correctly.

-----Original Message-----

I suspect it is the "error" of having a **HUGE** value in db_block_buffers and it's constantly crunching memory trying to figure out which ones to free up. It's only 256 meg, but depending on load, it may be too much. SGA is 687 meg.
