Home -> Community -> Mailing Lists -> Oracle-L -> RE: Windows NT and Virtual Memory
Rajesh,
I had the same problem when we migrated to Oracle817. The solution was to
setup MTS.
Our server runs about 450 sessions/connections at a time now, no problems.
I have the server set up to mts_servers = 15 and an initial dispatchers =
10.
This has been working fine for our system for approx 1yr now.
Hope this helps
Rgds
Denham

To: Multiple recipients of list ORACLE-L
Operating System: Windows NT 4.0 with SP 6a Oracle Version : 8.1.7
We recently migrated an Oracle database from one Windoze NT box to another. The NT administrators claim that the NT boxes are indentical in all respects, except that the old one had Service Pack 4. We have recreated the database on the new box with exactly indentical initialization paremeters, file sizes, extent sizes, et all.
The database gleefully accepts all connections upto about 220 users (V$license, v$session). When the 221st user tries to logon, the TNS-12500: Unable to start a dedicated server process is thrown. After all the troubleshooting (Connect timeouts, Disable otracing, tracing client), we discovered that as soon as the Virtual memory comes approaches 1.7Gb, this problem starts happening. I read articles on Metalink which suggested that this is a limitation with Windows NT, and suggests some recommendation to delay this problem.
So, we recommended the same to business. But now they wish to know why these errors never occured in the old NT server. And to further worsen matters, the old server has been cleaned up. So, I have no way of going back and Checking.
Has anyone else on this list encountered the same problem? Possible workarounds, if any?
Thanks
Raj
