Yesterday I did an new installation of 10g RAC on a 2 node Tru64 cluster. It was totally clean, unlike the 9i to 10g upgrades I’ve done before.
Once the software was installed I had to create a copy of our current production system on it from an RMAN backup done using HP Data Protector. The whole restore and recovery went through without a hitch.
Days like that restore your faith in Oracle, and your backups 🙂
