Was doing some testing and discovered that if a tablespace is in backup mode,
a manual failover will not succeed. It comes up on the second box, oracle
mounts, but the database does not open. You get a message indicating media
recovery is necessary. This is easy enough to resolve, but it does create
an exposure while our tablespaces are in backup mode for hot backups. Does
anyone have a workaround for this problem? It must be pretty common.
