How to backup AUXILIARY database (done by duplication)

[joyqli]

Hi guys,

I was able to duplicate (via active or backup-base) from target to auxiliary.

Now I run into 3 "issues" and can't help wondering if they are suppose to be like that. See below.

1. After auxiliary db (wamsdup) is duplicated, I connected the auxiliary db to RMAN utility:
rman target / catalog rman/rman@catd

[COLOR="red"]When doing list incarnation, it shows the incarnation of the TARGET database from which it was duplicated:
[/COLOR], IS THIS CORRECT??

connected to target database: WAMSDUP (DBID=4099367134)
connected to recovery catalog database

RMAN> list incarnation;

1 2 WAMS11 3084316962 CURRENT 1308979 10-MAR-11

2. I then registered it into the catalog, but list incarnation shows both the target and the auxiliary: Is this correct or is my duplication inaccurate? Why does the incarnation stored info both the target and the auxiliary?

3. After registering the auxiliary into catalog, when I get into the target (source) db rman and do a list incarnation, it seems the auxiliary incarnation is recorded in the target db, any idea why?List of Database Incarnations

4. IF I do NOT connect to the catalog, only connect to the auxiliary as target, rman target /, then list incarnation shows the correct info:
using target database control file instead of recovery catalog

5. I wonder IF it is possible to register & configure the auxiliary database in the RMAN catalog and start backing it up. Have anyone of you guys done that before? or is this a mute point?

THANKS!!!!

I forgot the syntax:

list incarnation of database.

Else, of course catalog will show all REGISTERED databases' incarnations.
