Re: oracle sessions from term server
The TCP connection to Oracle server process (or dispatcher) port probably remains alive for some reason. When TCP connection is dropped from OS, the session dies immediately.So you should check why are sessions TCP connections maintained or set sqlnet.expire_time to one hour or smth, to kill sessions after an hour even if TCP connection for given sessionis still open.

Re: oracle sessions from term server
Hello, We have a similar situation with our Win2K terminal server-based sessions and our Win2K database server (8.1.7.4.1) although we have not introduced the use of SQLNET.EXPIRE_TIME in this case. As detailed in Metalink Doc ID 151972.1 (Dead Connection Detection (DCD) Explained), there are limitations in a Windows environment. These limitations are not restircted to a Windows-only environment however, as I have seen the same behaviour with NT4 terminal servers connecting to an AIX database server (8.1.7.2.1). The use of DCD is worth investigating. Other Metalink documents that may be useful are 1018160.6 (Common Questions About Dead Connection Detection (DCD)) and in particular, check out bug 2167389 (THREAD LEAK WITH DCD SET CAUSES NT TO HANG) If you discover that that DCD introduces more problems than it solves, then it is trivial to disable - simple hash out the SQLNET.EXPIRE_TIME parameter in the SQLNET.ORA file - no reboot required.

Re: oracle sessions from term server
Thanks Tanel , for the reply . Does it mean that windows term server is keeping that tcp connection alive although user session is dropped from OS(windows terminal server ) . Is there a way i can trace this tcp session .

Re: oracle sessions from term server
I used to deal with this on a regular basis. Sun servers, PC clients. User reboots PC, session persists. It does not require that the TCP session still exists. We didn't use DCD at the time, as it was kind of buggy. You may want to give that a try now. Jared On Thu, 2003-08-28 at 08:54, AK wrote: Thanks Tanel , for the reply .
