RE: Database slowdown after 100 days uptime

As far as my experience ,my site also got this problem , that is why every weekend we run a shutdown and restart the Unix box also in order to clean up some of the unwanted redo log and refresh the memory as well.

it seen like our system become 6*24 instead of 7*24 , but in the business view is we open only until Saturday.

but now we have branch open in shopping mall ,and they work in Sunday ?

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.
My plan is to take it up to 8.1.7 as those systems are not showing that sort of
problem.
