If this is a SAN based FRA, can you not use a technology such as
ShadowImage (HDS) or BCV (EMC) to split the mirror and *mount* it (not

(any host is ok but you kill two birds with one stone if this is the
standby host) Note that the FRA by default is not only the backup area,
but has the archive logs, flashback logs, etc, so you cannot take it
offline. Offloading such work requires a *complete* detach - via a
mirror such as what I describe above...
John,
Thanks. The FRA is in fact on storage that is mounted on the
alternate host via NFS while simultaneously mounted on the primary.
The problem is making RMAN read from the local NFS mount on the
alternate host, rather than calling RMAN to start a server process on
the primary, which is the default behavior when specifying the target.
