Hi Experts,

I am new to RMAN, while executing a clone script i got the below error : -

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 11/15/2011 20:07:34
RMAN-12010: automatic channel allocation initialization failed
RMAN-06758: DB_UNIQUE_NAME is not unique in the recovery catalog

Here i understand that RMAN couldn't find which SPFILE to use to restore the target DB.

How do i check for the DB_UNIQUE_NAME in recovery catalog?

The proposed solution that i found was

Use the FOR DB_UNIQUE_NAME option to specify the name of the instance whose parameter file you want to restore

Can anyone please explain me this as i fail to understand how to implement this in my clone script?

Thank you

>>how to implement this in my clone script?
Please post your "clone" script.
Is this a dataguard implementation?

1) The same script works fine for other databases.
2) No it is not a Dataguard implementation

Hi,

I checked the Recovery Catalog database and found this : -

SQL> select * from rc_database where name like '%LUU%';

    DB_KEY  DBINC_KEY       DBID NAME     RESETLOGS_CHANGE# RESETLOGS_TIME
---------- ---------- ---------- -------- ----------------- -------------------
  14663342   14663343 2901056869 LUU                      1 24.02.2009-15:00:53
  25597660   25718191 3444043551 URLUU           5.5208E+12 07.06.2011-13:10:10

Here database URLUU no longer exists in the Filesystem, therefore I thought it is best to unregister this database.

RMAN> set DBID 3444043551;

executing command: SET DBID
database name is "URLUU" and DBID is 3444043551

RMAN> unregister database;

database name is "URLUU" and DBID is 3444043551

Do you really want to unregister the database (enter YES or NO)? YES
database unregistered from the recovery catalog

RMAN> exit

Checked the Recovery Catalog : -

SQL>  select * from rc_database where name like '%LUU%';

    DB_KEY  DBINC_KEY       DBID NAME     RESETLOGS_CHANGE# RESETLOGS_TIME
---------- ---------- ---------- -------- ----------------- -------------------
  14663342   14663343 2901056869 LUU                      1 24.02.2009-15:00:53

But on running the Clone Script I still get the same Error

RMAN-06758: DB_UNIQUE_NAME is not unique in the recovery catalog

Again,
unless you post the asked information (scripts, initfiles used etc), I really cannot help.
Guessing will not always work for me.

restore spfile for db_unique_name is supposed to be used only in dataguard configuraitons.

Hi,

I checked the db_unique_name of database from RMAN

RMAN> list db_unique_name of database;


List of Databases
DB Key  DB Name  DB ID            Database Role    Db_unique_name
------- ------- ----------------- ---------------  ------------------
14663342 LUU      2901056869       PRIMARY          LUU
14663342 LUU      2901056869       STANDBY          URLUU

I think if I UNREGISTER Db_unique_name URLUU, it should solve the issue

RMAN>  UNREGISTER DB_UNIQUE_NAME URLUU;

Please provide me with your inputs.

Thank You

Quoting you from your previous post
>> 2) No it is not a Dataguard implementation

Quoting you again.

14663342 LUU 2901056869 STANDBY URLUU

Which one of 'em is true?

As said earlier

restore spfile for db_unique_Name <yourDBUniquenameThatyouwant>
