Check in Task Manager, Performance Tab...

upper right corner, Physical Memory (K) Total = 
lower left corner, Commit Charge (K) Peak = 

Commit Charge Peak should be less than half physical RAM, otherwise users
may not be able to connect.

Oracle can't be swapped to disk in Windows because it updates the data block
and other headers regularly, and it's too fast for the Windows virtual
memory manager.  I don't know if this is the case only for busy databases,
but I bumped into that here.

Windows splits memory equally between kernel and user processes, that means
you get to use about half the available RAM on your machine.  

User sessions can usually be swapped to disk (I think), if they are
inactive.

I would be curious to hear what memory utilization stats you have on the
machine.

Hello Gurus

I had a weird one to day, all access to Oracle on our oracle database was
suddenly lost....
When you try to connect it says that Oracle is on available.
However the DB has been up for more than 70 days. The other thing the
service was running and the Oracle process and listener was running?
No errors in the logs, nothing.
Server: Win2k, Oracle 817.


Has anyone experienced this before???

TIA
