DBAs,

I was trying to duplicate a database locally using Rman.
I started the auxiliary database with nomount from sql*plus.
But when I tried to allocate the auxiliary channel.
I got the following error:
(The weird thing is that I can correctly connect to the aux database as shown in the following.)

MAN> CONNECT AUXILIARY sys/lily@ODLILY

connected to auxiliary database (not started)

RMAN> RUN {
2>
3> ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE DISK;}

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of allocate command at 11/02/2005 11:24:40

Any idea?
Thanks!
