Pinning Data In Cache

edited Dec 18, 2008 12:29AM in Database Administration (MOSC) 4 comments
I have a fact table that is interval partitioned by hour.  It is stored in a tablespace that has a 16k block size and as such we have a 16k cache (db_16k_cache_size) set up. I'd like to be sure that the last hours worth of data is cached/pinned in memory as well as possible so that regular aggregate jobs can run and perform well as possible.  Most operations are done on the most recent data.  I have a couple of questions:

1.   What is the best way to ensure the last hour worth of data is pinned in memory?

Howdy, Stranger!
