Database Software

I created a standby database using RMAN backup file.

1. backup primary database and create standby control file
RMAN> run
{
allocate channel c1 type disk;
backup database format '/u01/app/oracle/admin/confgdb/db_%u_%d_%s';
backup format '/u01/app/oracle/admin/confgdb/log_t%t_s%s_p%p' (archivelog all);
}

SQL> alter database create standby controlfile as '/u01/app/oracle/admin/confgdb/control01.dbf';

2. Get thest file from primary database server via sftp command.

3. copy init file from primary database to standby database. Add following:
standby_file_management=auto
fal_server='DBPRIMARY'
fal_client='DBSTANDBY'

4. startup standby database
SQL> startup nomount pfile='/u01/app/oracle/admin/confgdb/initconfgdb.ora';
SQL> alter database mount standby database;

5. connect mounted standby database and start to restore backup file
$ $ORACLE_HOME/bin/rman target /
RMAN> restore database;

Starting restore at 26-MAR-08
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1

I do not know the root cause and how to resolve it.

Can you help me to find the root cause?
