Forms 9i disconnects after one hour

Question

I have a forms 9i application running against a 9i database. There is no 9iAS middle tier - it just uses the Forms OC4J listener servlet.
The form calls a database procedure whic takes a long time to execute - in fact it takes over an hour. After exactly one hour, the form disconnects with the following stack in the application.log file:
5/21/03 10:21 PM forms90web: Forms session <1> aborted: unable to communicate with runtime process.
5/21/03 10:21 PM forms90web: Forms session <1> exception stack trace:

Any ideas? Is the disconnection coing from the forms end or the database end? What can I do about it?

Answer 1

no it is not a server side rule.... the only thing the server accepts is idle time. setting it to 0 means always on. but even with high traffic over the vpn tunnel, the connection gets interrupted.
in programs like ipsecuritas i can set things like duration of connection, but ipsecuritas does not support to get an ip address in the range of the network in the dhcp pool of the router. it only does natting. routing is not possible.
so ipsecuritas is not disconnecting but not sufficients, so it is not a server side thing.
