Go buy a tool? Here is an idea instead ...
Write a small Perl (pick your favorite language here) script that looks at /etc/oratab followed by a check to see if each of the instances listed in /etc/oratab is up on the side where it is checking. It then log in as a schema (we call it) called heartbeat, insert a row into a table with sysdate. Wait 3 seconds, retrieve the row and checks the time difference. If it is more than 5 seconds, you have a potential delay somewhere and have it alert appropriate people. (If it is night, page your VP with "This is your heartbeat calling ... we have a problem" ...)
Life is great with "cron" ...
