urouter.sh

Description

The urouter.sh file is a shell script that starts the Uniface Router, and ensures that it is restarted in case of failure. By default, the Uniface Router is restarted every time it fails for an unknown reason, and the last three core dumps are stored.

You can edit this file to change how the Uniface Router recovers from crashes.
