This script uses the Cloudscape Java API to;
Start the Cloudscape network server.
Ping the network server to ensure it has started.
Get the server system infomation.
Get the server runtime information.
Runs in the background and pings the server continously to ensure it has started. Generates an email alert if the server fails.
It can be run as a service under Windows or a daemon on Unix. Requires Tclblend.
