I'm trying to follow the procedure on page 13-21 in the 10.2 Backup and
Recovery advanced users guide but i'm running into a problem.

The manual states that the auxiliary instance should be started NOMOUNT,
however when I try to connect to the auxiliary instance I receive the
following error:

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-04006: error from auxiliary database: ORA-12528: TNS:listener: all
appropriate instances are blocking new connections

How does rman connect to a host in nomount when the listener is blocking
all connections?


target is host1 (source)
auxiliary is host2 (destination)
rman is running on host3  (central rman server and houses catalog)

The manual isn't clear where I need to be running the rman commands -
the manual implies running rman from the target ("CONNECT TARGET /;")
but that seems incorrect. I tried running rman directly from the target
but the connect to the auxiliary in nomount still fails with the same
error (listener blocking new connections).

Any ideas?
