If I recall Graham Wood's presentation at UKOUG correctly (and can read my notes), in 10gR1 or earlier, it is updated when the statement finishes. In 10gR2, it is update every 5 seconds.
I have not tested this, so take with a grain of salt. Regards, Daniel Fink Binh Pham wrote:
K,Thanks. However, I kept querying the v$sqlarea for the same hash_value and did not see it changed for a while later (much longer than 3 seconds).------------------------------------------------------------------------ From: /K Gopalakrishnan <kaygopal@xxxxxxxxx>/ Reply-To: /kaygopal@xxxxxxxxx/ To: /binhpham15@xxxxxxxxxxx, oracle-l@xxxxxxxxxxxxx/ Subject: /Re: v$sqlarea update frequency/ Date: /Fri, 12 Jan 2007 15:06:32 -0800 (PST)/ IIRC it is 3 seconds.
