hi, List friends,
Oracle has been promoting this flash cache as second tier cache for
oracle for a while; Just wondering whether anyone has used this within the
industry?
We typically have 30gb-60gb SGA supporting 1TB-4TB database; We found
usually 30gb or 60gb cache size does not really matter much for majority of
our database(some has big diff though, depends on workload profile/active
dataset); But a 300gb flashdisk might make huge difference, and help reduce
the IOPS load on the SAN side?
Looking forward to industry experience;
Thx
