FRM-92102 is Gerneric Error maybe occur for more than one reasons :
1-Network
2-Proxy
3-http
4-Session Time
But today i will discuss the problem On oracle Application server 10g .
Description for the problem like the following when you try to connect on your deploy application On OAS 10g it’s gives the above error from 1-5 minutes.
I will give you more than one solution maybe it will be related to the above problem and you try them separately to see which one will be valid for you :
You will find it $ORACLE_HOME/forms/server/default.env
Just increase the value .
Sqlnet.Inbound_connection_timeout = 0
Note : if your can’t find this parameter in the SQLNET.ORA you cant add it .
Hope this will work
