We have a lot of posts todo the same – duplicate. But my post is complete steps to duplicate the database, and we need pay attention if the database will be duplicated on the same server. What we need take care with all attention on it? Redo log files, datafiles and controlfiles never be recreated/created at same source locations. All backups are under the location /backups/bkprman in my lab. Let’s start !

Source database – bdo

Check the locations from source database. Make sure when you are duplicating - any of these files will be replaced. Mistakes are done with redo logfiles members when we are duplicating. Take care to rename all files and check before open it. Take notes of the locations below.

Select name from v$datafile;
Select name from v$controlfile;
Select member from v$logfile;

Target database – TESTE

Before open the target database check same queries below.

Select name from v$datafile;
Select name from v$controlfile;
Select member from v$logfile;

Add database to /etc/oratab

Add this line to the end of /etc/oratab

TESTE:/u01/app/oracle/product/11.2.0/db_1:Y

Listener.ora

Add the listener.ora details below and reload listener – edit your listener.ora and lsnrctl reload it

vi $ORACLE_HOME/network/admin/listener.ora


SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = TESTE)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = TESTE)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = srvoraclestby)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

Password file creation

We need create the password file and use entries=5 sometimes we get error when connecting to auxiliary.

cd $ORACLE_HOME/dbs
orapwd file=orapwTESTE password=oracle ignorecase=y entries=5

Create new file: initTESTE.ora

# Minimum Requirement.
DB_NAME='bdo'

Create new file: duplicateTESTE.sql

DUPLICATE DATABASE TO TESTE
  SPFILE
    parameter_value_convert ('bdo','TESTE')
    set db_file_name_convert='+DATA/bdo/datafile/','/backups/oradata/TESTE/','+DATA/','/backups/oradata/TESTE/'
    set log_file_name_convert='+DATA/bdo/datafile/','/backups/oradata/TESTE/','+DATA/bdo/onlinelog/','/backups/oradata/TESTE/'
    set control_files='/backups/oradata/TESTE/control01.ctl'
    set db_name='TESTE'
    set log_archive_dest_1='location=/stage/archive'
    set log_archive_dest=''
    set DB_CREATE_ONLINE_LOG_DEST_1='/backups/oradata/TESTE/'
    set DB_CREATE_FILE_DEST='/backups/oradata/TESTE/'
    set audit_trail='none'
    set remote_login_passwordfile='EXCLUSIVE'
  BACKUP LOCATION '/backups/bkprman'
  NOFILENAMECHECK;

Create new file: duplicateTESTE.sh

. oraenv <<< TESTE

sqlplus / as sysdba <<EOF
shut abort
startup nomount pfile='/stage/scripts/initTESTE.ora';
exit
EOF
# rm -Rf $ORACLE_BASE/admin/$ORACLE_SID/adump
# mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/adump
# Remove the old datafiles
rm -Rf /backups/oradata/TESTE/*

rman auxiliary sys/oracle cmdfile=/stage/scripts/duplicaTESTE.sql log=/stage/scripts/duplicaTESTE.log

sqlplus / as sysdba <<EOF
alter database open resetlogs;
exit
EOF

Execute the rman restore in background

 nohup ./duplicateTESTE.sh &

Check the results

Before open the database, check if redo log groups are in the correct location

Check if the datafiles have been created in a different location from production database before you open the database with resetlogs option. If all is fine, open database with resetlogs option.

. oraenv <<< TESTE
sqlplus / as sysdba
Select name from v$datafile;
Select name from v$controlfile;
Select member from v$logfile;
alter database open resetlogs;
select status from v$instance;
exit

Errors and solutions when using duplicate with auxiliary and backup location

RMAN-06136: ORACLE error from auxiliary database: ORA-01507: database not mounted

Solution:
When connecting to auxiliary instance, password file is not working. Recreate password file or use this connection with the correct password like below:

rman auxiliary sys/oracle

ORA-19504: failed to create file

Solution:
Update/revise the parameters on file restoreTESTE.sql:

parameter_value_convert ('bdo','TESTE')
    set db_file_name_convert='+DATA/bdo/datafile/','/backups/oradata/TESTE/','+DATA/','/backups/oradata/TESTE/'
    set log_file_name_convert='+DATA/bdo/datafile/','/backups/oradata/TESTE/','+DATA/','/backups/oradata/TESTE/'
    set control_files='/backups/oradata/TESTE/control01.ctl'
    set log_archive_dest_1='location=/stage/archive'
    set log_archive_dest=''
    set DB_CREATE_ONLINE_LOG_DEST_1='/backups/oradata/TESTE/'
    set DB_CREATE_FILE_DEST='/backups/oradata/TESTE/'
    set audit_trail='none'

ORA-09925: Unable to create audit trail file

Solution:
update the parameter on file restoreTESTE.sql:

set audit_trail='none'

ORA-01261: Parameter db_create_online_log_dest_1 destination string cannot be translated

Solution:
Make sure the directory exists/update the location to one existent directory on file restoreTESTE.sql:

DB_CREATE_ONLINE_LOG_DEST_1='/backups/oradata/TESTE/'

RMAN-06403: could not obtain a fully authorized session

Solution:
Recreate the password file:

cd /u01/app/oracle/product/11.2.0/db_1/dbs
rm orapwTESTE
orapwd file=orapwTESTE password=oracle ignorecase=y entries=5

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Solution:
Update the listener.ora e try to reload the listener :

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = TESTE)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)

WARNING: The following temporary tablespaces contain no files.
         This condition can occur when a backup controlfile has
