RE: Database slowdown after 100 days uptime
Hi Bruce Yep there is something on Metalink about this when server uptime is 248 days (I know it sounds unbelievable). Happened to me, databases slowing/hanging and I could only shutdown abort databases. Rebooted and everything worked fine.

Re: Database slowdown after 100 days uptime
Keep an eye on free memory -- one of our similar systems has to be restarted every 60 days to prevent the behaviour you're encountering. We haven't determined the source of the memory leak, but if we permit it to continue eventually the DB stops responding and cannot be shut down. This system does some analytical work for us so it has different connection and activity profiles than the others, so I've a limited basis for comparison, but the other 8.1.5 databse (this one's data source) shows similar problems over a longer period.

Re: Database slowdown after 100 days uptime
Hi, There is an alert (Note:118228.1) ALERT: Hang During Startup/Shutdown on Unix When System Uptime 248 Days. But, you are using NT. do you have other errors in alert.log before crash or is there core.log ? "Reardon, Bruce (CALBBAY)" wrote: Hi, We're running Oracle 8.1.5.1.1 on NT 4.
