Yes, it is possible.

Look for "Graceful Switchover and Switchback" Oracle Standby Database Versions 7.3, 8.0, 8.1 by Lawrence To.
The main point is to substitute the online redo logs, never activating the standby database.

Quick question. Is it a fair statement to say that using Oracle's hot standby database allows you recoverability up to the last archive log, but would NOT recover to the latest redo log (prior to a log switch). In other words, the potential to lose transactions is very high if you depend on this for failover (not good for e-commerce type databases). Would it be possible to somehow mirror redo logs across to the failover server and apply them when activating the standby database, or is the only real solution clustering or something like DoubleTake?

Am I making sense?

Thanks,

Ed
