Home -> Community -> Mailing Lists -> Oracle-L -> RE: Problem with many (160 - 170) sessions in the database on
just my input.
where are the load metrics documented, meaning where does it say 5M or more per session? i want to know for future reference.
we're putting in a solution, oracle 8i on windows 2000/windows 2000 advanced server ~4-to-8G of RAM so there are options if you need additional RAM in excess of 4G. no true *nix expertise here and it's our fledgling implementation but based on specs we should be covered.
say it's 10M a session, 500 users is about 5G with plenty left over for O/S, SGA, etc...

I agree with Goulet.
In contrast to ur rather powerful machine my NT server handles abuot 200
connections on a single database with just 1 CPU and 512 MB RAM. Ofcourse
preformance is pathetic - but what can one do with Windows anyways ??
I asked management to junk the machine and in a months time we will migrate
to a brand new Sun Solaris Server !!
The only way we survive with the NT machine is boot it once a week !!

Jonas,
Solution, dump Windows and get onto Linux or buy a real Unix machine.

Hello
We are running into a little problem with an Oracle installation. The server OS is Windows NT, SP6, and the version of Oracle is 7.3.4.5.0. The server have 4 processes, we have about 1,7 G primary memory and about 2 G of memory on swap disk. We have 4 processes in the machine. One of these is reserved for the OS, and Oracle uses the other 3.
We we reach around 170 sessions in the database, the database sometimes goes down and we have to perform a restart. The 3 process Oracle use are all at about 100% in task manager. The memory use is somewhere around 1,3 G. Then we can run the database for aboout 4 more hours, then we have to restart. Sometimes we have to restart around lunch everyday.
Now I have heard the Windows NT have a limit of how much memory one process might use, and that limit is somewhere around 1,7 G, and that that might be our problem.
We are planing to upgrade to Oracle 8.1.7 and to Windows NT 4 Enterprise Edition or to Windows 2000 Advanced Server. Does anyone know if this can help? Should we put more memory or more processes in the machine?
Any help is appreacheated
Regards
/Jonas
