RE: Sun Cluster and VCS failover
We have several 2-way VCS clusters with 16 and 10 CPU's per server. We found that the failover time was proportionate with the number of file systems that need to be mounted by the take-over node. We consolidated the file systems containing the datafiles down to 1 and each database takes 2-3 minutes 'till service is fully restored.

RE: Sun Cluster and VCS failover
Nick: On our SunCluster 2-node E4500's with 8 CPU's (Oracle 8.0.5) it takes us around 12 to 15 minutes. HTH.

RE: Sun Cluster and VCS failover
I would think 12 to 15 minutes still too high. Damagement would generally specify a max of 5 minutes. Have you found out why it takes 12 to 15 minutes ? Do the File Systems take so long or does the Instance Recovery take so long ? Do you have to put a sleep in the startup scripts [when I setup a failover cluster for Oracle Apps with Oracle Web Application Server 3.0.2, I put in a sleep of 30seconds for the Web server -- WAS302 has to have the physical host-name hardcoded in the wrb.app file so I maintained two copies of the file and the startup script would copy in the correct one, depending on the hostname, as wrb.app but sometimes it wouldn't startup immediately ; I had to put a sleep after the file copy].
