thanks.

Subject: sqlnet.expire_time support in 9.2 on NT (w2k)
RDBMS Version:: 9.2.0.4
Operating System and Version:: MS W2K Advanced Server SP4
Error Number (if applicable)::

sqlnet.expire_time support in 9.2 on NT (w2k)
sqlnet.expire_time is not working properly for me in 9.2.0.4.0 on w2k.
In a trace file (trace_level=16)
I am seeing the message:
nstimarmed: entry
nstimarmed: no timer allocated
nstimarmed: normal exit
I have read the following docs:
Note:151972.1 Dead Connection Detection (DCD) Explained
Note:1018160.6 Common Questions About Dead Connection Detection (DCD)
Note:1006809.6 DEAD CONNECTION DETECTION WON'T WORK
Orac!

and Jonathan Gennick's Oracle Net8 Troubleshooting Guide.
parameters:
sqlnet.expire_time = 10
in the file %ORACLE_HOME%\network\admin\sqlnet.ora
environment variable
tns_admin = 9.2 home\network\admin, as that was referenced in one of the above docs as a possible remedy.
the listener service has been cycled (since the file sqlnet.ora was changed).
This server does have 2 oracle homes (8.1.7.4.6 and 9.2.0.4.0).
No Oracle TNS Listeners are in use that use the 8.1.7 home.
The 9.2 Home is the default home.
when examining a connection from my workstation to the server, the timer functionality is not being used.
1. Is the use of sqlnet.expire_time supported on win32 (at all)?
2. If 1 is true, under what release/patch is it supported?
3. if 1 !
is false,
has anyone had success with the following:
Use the standard TCP KeepAlive on Windows NT/2000:
- Open the registry under:
HKEY_LOCAL_MACHINE: SYSTEM: CurrentControlSet: Services: Tcpip: Parameters
- Add KeepAliveTime : REG_DWORD to the registry
- Set the value to a reasonable timeout.(decimal and NOT Hex)
Eg: (120000 = 2 minutes)
- Save this
- Reboot
and what are the downsides of such a workaround?
MTS / shared_server is not an option, as this is a client/server app that can move large volumes of data.
sqlnet.expire_timeout was supposed to be supported on 9.0.1 on win32.
thanks,
Paul
