Prepare the Standby database:
1. Put the database is in Archivelog mode
SQL> shutdown immediate;SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database open;
Confirmation:
SQL> archive log listDatabase log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 17
Next log sequence to archive 19
Current log sequence 19
2. Add Listener details for Standby database:
DR01 =(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dba.asteroid.com)(PORT = 1522))
)
)
3. Create init.ora for standby with just DB_NAME:
[oracle@dba dbs]$ echo 'DB_NAME=DR01' > $ORACLE_HOME/dbs/initDR01.ora4. Create password file for Standby
orapwd file=$ORACLE_HOME/dbs/orapwdr01 password=0racleMake sure to use the same password as the SYS user password of PRIMARY database.
5. Start the Standby DB in nomount state.
Prepare the Primary database:
1. Create SRL on Primary database; this is needed for standby creation RMAN will then create this for you on Standby.
SQL> select GROUP#, THREAD#, MEMBERS from v$log;GROUP# THREAD# MEMBERS

1 1 1
2 1 1
3 1 1
Create the Standby using RMAN:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-04006: error from auxiliary database: ORA-12154: TNS:could not resolve the connect identifier specified
This happens because the listener process gets registered only after the database is in the mount state, whereas our database is in Standby state.
Add the STATIC REGISTRATION DR init.ora:
LOCAL_LISTENER=DR01
