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].

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.
