We have been using Tidal 5.3 in a RAC cluster using Exadata for a few years now. We are in the middle of upgrade and using TES 6.1 with RAC on Exadata as well. If a node fails is it really a must for you to stop and restart Tidal it won't be pretty if you don't. So monitoring this is crucial.
Also, if you want to do multi cluster for DR or failover, we can't get that to work. The tnsnames.ora setting for multi host cluster failover doesn't work out of the box in JDBC thinclient,
There are very few instructions to do this on the web, and the one we found doesn't seem straight forward without needing a few properties exposed to customers.
So essentially we are resorting to modifying the host cluster manually in the jdbc parm of the props files if we do need to failover to aother cluster.
