Hi,
Please note that Data Guard is available for 8i as well. Latest version is 2.6.2 (Sun Solaris). Data Guard is a wrapper over a standby database; it will automates all the steps required to failover or switchover to the standby database. If combined with a Remote Mirroring technology (e.g. EMC SRDF in
 synchronous mode) to mirror the online redo logs on the standby host, it should help you acheive a 100% no data loss.

We're currently testing this solution on Solaris 2.7 with Oracle 8.1.7.1 EE. No plans for our production environment yet. It would be interesting to hear from someone who's currently using Data Guard in a PROD environment.

As Paul mentionned, FailSafe could be an option if you run on NT.
