The Patch for 1967363 on 8.1.7.2/8.1.7.2.1 has been out for some time now. (the patch will not be released for 8.1.7.1 or 8.1.7.0) I do have an 8.1.7.1 instance running and am waiting for scheduled downtime to upgrade to 8.1.7.2.1 + 1967363 on Tru64. This instance is only a test environment and, yet, I see high wait-time ratios for "cache buffer chains" latch in the PerfStat reports.
(On Solaris it is only 8.1.7.2 -- 8.1.7.2.1 was released only on certain platforms to replace a defective 8.1.7.2 which would not upgrade 8.1.7.1 to 8.1.7.2).

But I do not recall if the issue was damaging or not. So, 8.1.7.2.1 does not have this resolved, and I need to go to 8.1.7.3 ?

We got bit on 8.1.7.1 by a 'Cache Buffer Chains' latch contention bug (bug 1967363) that is not fixed until 8.1.7.3 or 9.0.2. The releases are supposed to be out in January, IIRC. --Scott ----- Original Message ----- To: "Multiple recipients of list ORACLE-L" <[EMAIL PROTECTED]> Sent: Wednesday, December 19, 2001 10:26 AM I am still waiting for Oracle 8.1.7.3 final release for 8.1.

Need to upgrade to 8.1.7.2.0. -----Original Message----- To: Multiple recipients of list ORACLE-L Sent: 12/18/01 5:50 PM Your SGA has become fragmented. You would not per chance be running 8.1.7 would you? If so I would go and do some searching on Metalink. I see an upgrade in your future. You could try flushing the SGA but if its what I think it is it won't help. A restart will for a while. -----Original Message----- Sent: Tuesday, December 18, 2001 4:30 PM To: Multiple recipients of list ORACLE-L Any idea what this means ?
