Sorry If I didn't express correctly=20 <MB> Ah, ok, I see. Well, obviously, the way the buffer cache is <MB> is managed has changed in 9i. I would guess it has to do with <MB> 9i's ability to grow and shrink the buffer cache dynamically, <MB> and the added layer(s?) of code to support that, but I haven't <MB> totally worked out how it fits together yet. -------Original Message------- =20 From: oracle-l@xxxxxxxxxxxxx Date: 07/21/04 15:51:15 To: oracle-l@xxxxxxxxxxxxx Subject: RE: recycle and keep buffer in other tablespace block sizes =20 Juan, =20 Did you read my previous posting? =20 In particular, the part where I said "I've figured out how to do this in 8i, but in 9i, I have not succeeded in writing such a query. I spent some time running in circles a few weeks ago, and never did get anywhere." =20 And then I detailed how my query works for 8i ONLY, and asked if anyone had worked it out for 9i........ =20 =20 =20 -Mark =20 =20 Mark J.
