High Availability Question

[azzazzello]

I have a Java-based network application running on Red Hat ES 3. I need to make it HA, to guard against software and hardware failure. I currently have a simple cronjob that every X minutes and restarts the service if its down, but that, obviously, is not good enough. I want to have a second server on standby that, and if it detects that the main server is down, it would bring itself online with the same IP, and launch this application. The main server, however, if it were to come up again, would see that its function was taken over, and put itself in standby. Both servers have dual nics for heartbeat, of course. I have done a little research on the subject, but perhaps someone here has some comments or can pinpoint me to correct literature, so that I would not have to pick up bits and peices here and there.

Instead of a cronjob, you can try "respawn" in the inittab


Hope that helps.
