Raj, Oracle can only use 2GB of RAM for all its processes under NT or Win2k unless you're using NT Enterprise Edition or Win2k Advanced Server and you set an NT / Win2k parameter to allow it to use up to 3GB or (yet another OS setup) 4GB and more.
Check out the Windows-specific docs for info. and references to papers on the MS site. I went through that investigation a while back, but the exact details have left my brain cell. ;-) Jack -------------------------------- Jack C.

Austin, Texas www.iNetProfit.com [EMAIL PROTECTED] (512)327-9068 -----Original Message----- [EMAIL PROTECTED] Sent: Friday, March 22, 2002 9:59 AM 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 -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Jack C.
