RMAN-05520: database name mismatch, auxiliary instance has ORADB

Question

Hi,
i am using Oracle 10g (10.2.0.1.0) in RHEL 5 server. i am trying to duplicate my primary database(ORADB) to standby database with name DEVDB in different server. I have taken an RMAN backup and transferred to standby server and now i am trying to duplicate with the below commands
[oracle@rhel5 data]$ rman target / auxiliary sys/oracle@DEVDB

Hello again;
Agreed. You have at least two issues.
Generally I change the SID
export ORACLE_SID=DEVDB
Then I start NOMOUNT using an INIT file.
Then this should be correct
connected to target database: ORADB (DBID=2542358497, not open)
connected to auxiliary database: ORADB (not mounted)h2. Later
I think I was wrong I would like to change my answer. I looked back and found my old notes and things are not as I stated above.
I used an INIT file ( standby side ) for cloning as follows :
db_name=RECOVER2
instance_name=RECOVER2
control_files=("/u01/app/oracle/oradata/RECOVER2/control01.ctl", "/u01/app/oracle/flash_recovery_area/RECOVER2/control02.ctl")
db_recovery_file_dest=/u01/app/oracle/flash_recovery_area
db_recovery_file_dest_size=4070572032
compatible=11.2.0.0.0
core_dump_dest='/u01/app/oracle/diag/rdbms/recover2/RECOVER2/cdump'
db_block_size=8192
audit_file_dest=/u01/app/oracle/admin/RECOVER2/adump
undo_tablespace=UNDOTBS1
undo_management = AUTO
undo_retention=10800So for the duplicate I don't set DB_UNIQUE_NAME
I Backed up the target database as shown here with the ‘backup current controlfile for standby format’ command:
RMAN RUN {
allocate channel d1 type disk;
backup format '/u01/backups/RECOVER2/df_t%t_s%s_p%p' database;
sql 'alter system archive log current';
backup format '/u01/backups/RECOVER2/al_t%t_s%s_p%p' archivelog all;
backup current controlfile for standby format '/u01/backups/RECOVER2/sb_t%t_s%s_p%p';
release channel d1;
}I did a startup the standby as follows : ( Notice you are correct about the SID and I was incorrect )
export ORACLE_SID=RECOVER2
/home/oracle:SRECOVER2 >sysplus "/ as sysdba"
Connected to an idle instance.
SQL> startup nomount pfile='/u01/app/oracle/admin/RECOVER2/pfile/initRECOVER2.ora';I started RMAN like this :
/home/oracle:SRECOVER2 >export ORACLE_SID=RECOVER2
rman target sys/password@recover2 auxiliary /

connected to target database: RECOVER2 (DBID=3806912436)
connected to auxiliary database: RECOVER2 (not mounted)So you connect to the Primary, but the auxiliary should show "not mounted"
Finally I issue the duplicate command
RMAN> run {
2> allocate channel C1 device type disk;
3> allocate auxiliary channel C2 device type disk;
4> duplicate target database for standby nofilenamecheck;
5> }Best Regards
