data studio disconnects after inactivity
We are using Data Studio v2.2 on windows to connect to DB2 v9.5 on Linux .
After a while without use this disconnects and drops any temporary tables.
I's causing some users a lot of dificulty.

Is there any way of preventing or extending this disconnect?
Is it controlled from the client?

My guess is that your connection is being dropped without your knowledge. This can be controlled from the server. What is the output of: "cat /proc/sys/net/ipv4/tcp_keepalive_time"?

Thanks
Would that be on the DB2 server which I don't have access to - onlt via a database connection.

Got someone to look and he says
/proc/sys/net doesn't exist
/proc/sys does.

Sorry, I do not know anything about SUSE. Have them figure out what the keepalive_time is for the system.
