How can I get an e-mail alert when my oracle database comes up or down?
I have a database that I need to know when it goes down (it would be nice to know if it has come back up), preferably from a remote machine. Conceivably I could hack together something that TNSPings my DB and e-mails me when that changes, but I'm hoping there's a free package out there. Something that would run on windows.
Any strong recommendations?
