Hello, We are planning on a new HA/DR solution for a new application that we are building. Most of our databases sit on SAN which is synchronosuly replicated via SRDF to a DR site. The users for this application want 2 hr window within which the DB needs to available if it goes down. The vendor recommends clustering, but I am also looking at Dataguard with Fast start failover. The physical standby can be at the DR site. The DB will be on 11g. Has anyone used 11g DG with FSF? Any specific issues? Does the DB come up quickly without any problem if the primary DB goes down? -- Thanks, Ram.
