There is a slight issue with the oracle RA: the RA kills all processes it finds that belong top oracle, after a shutdown. this includes the listener. during normal takeover/failover situations that is no problem, but if you have an erratic ping node, and the systems starts a failover, but then decides to stop the failover and stay on the current node, because the ping resource is no longer faulty, this becomes an issue. we have experienced a number of situations, where it recovered after stopping oracle, but before stopping the listener. when the cluster then starts oracle again, it leaves the listener untouched -and dead. this of course is ony an issue, if the monitoring resource is not set to restart in case of a failure. Mit freundlichen Grüßen / Best Regards

No. We have oracle and oralsnr resource agents, so you should be good to go with pacemaker.
