I have a site that is connected to the main site via a VPN connection.
When the users leave the Siebel application open and idle for more than 1 hour they receive the following errors:
Generic SSA NOTOK error message
An error has occured preparing a Sql statement
ORA-03113: end-of-file on communication channel.

the users have no problems with any other applications and the retreive email via Outlook through this VPN connection as well.

Any ideas would be apprecaited.

Hi jmurray110,
   This "problem" can be result of many things:
   * Oracle closing automatically some connections that are inactive for long time
   * Some Connection Pooling that reuses connections
   * Network connection cuts that drop the connection

  Now, you should try to eliminate possible sources, and in case speak with the siebel application support to check for this problem.
  It is a generic problem, and you might look into the trace files on the server of the client sessions to check for more information.

i have found out that the Cisco PIX firewall / VPN device was causing the timeout to occur as it would expire the PAT after an hour of inactivity. I was able to bump the setting and reslove the issue.

Thanks for the suggestions though.
