Home -> Community -> Mailing Lists -> Oracle-L -> RE: Pinning Tables
Well....to a first approximation, yes.
But, the way it used to work was that db blocks (even those from a full scan) went on the hot end of the list, and could still be dropped off the cold end, but it was far far less likely.
Now? Who knows...(well, not me, and I ain't RTFM'ing tonight!)

Subject: RE: Pinning Tables
Try: ALTER TABLE tablename CACHE;
The table will stay in the buffer cache and not get rolled out. This is basically used for small lookup tables like security tables that are accessed over and over.

No, pinning is for the code: sql, procedures/functions/packages and sequences. Take a look of the package dbms_shared_pool.
