Hi,
This just seems weird. I look at our SPFILE: *.shared_pool_size=2G
I query v$parameter: 1073741824
I ran a query:
SHARED_POOL_USED SHARED_POOL_SIZE SHARED_POOL_AVAILPCT_SHARED_POOL_AVL
---------------- ---------------- ------------------------------------ 2107.04836 1024 0205.766441
Ok, so if I have 2GB in my spfile, and I bounced my database, why is it reading 1GB, unless I'm a dork and cannot read properly.......Size = 1GB and used = 2GB??
Our sql library cache miss ratio says 99%, using that Spotlight utility and the latch waits are about 10%. So, we figure we have a problem.....
