2 Buffer Cache Questions
2 Buffer Cache Questions
- If you select * from a table, shouldn't that load the whole table
into the database buffer cache, provided it fits. I have a script that
I found that shows me what's in the cache, but I cannot seem to make
100% of a tables block fit. I could not seem to find the answer in the
concepts manual.
- What's does system put in the buffer cache. We notice that after
starting the db, system will occupy a good chunk of the buffer cache,
but that will start to decrease as various queries are run and the data
begins to fill the cache.
