I have Oracle10g running on Solaris 10. The configuration of the OS is standard, and there is a packet filter firewall running on the server.
When I run a long query using sqldeveloper, the server reset the connection after 15 minutes of inactivity.
The timeline is:
- client establishes the connection to server port 1521, no ssl
- server accept and receives the query from the client. the last packet exchanged is a TCP ACK from the server to the client
- ... 15 minutes (to the second) pass
- server send a RST packet to the client, and nothing else is exchanged between the hosts afterward
I couldn't find any timeout parameter for TNS listener, so I'm guessing it might be a solaris or packet filter issue ?
