Rman Duplicate from noarchivelog mode target database

Overview
Oracle Recovery Manager (RMAN) provides a comprehensive foundation for efficiently backing up and recovering the Oracle databases, it provides a common interface, via command line and Enterprise Manager, for backup tasks across different host operating systems, automates administration of your backup strategies.
In this scenario we are performing active duplication and source database is in no archive log mode.
When you issue the command to duplicate database from target database where source Database is running in noarchivelog mode, you will receive following error.
ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode 
 On this situation we have one solution put the target database in mount stage and perform the steps.
Target (source) details:
Database Name
dhstg
Hostname
Nsmdev01
Ip Address
172.16.110.18
OS
Linux
Version
x86_64
Datafile Location
/data1/dhstg
Backup Location
/backup/rman_backup

Tns details:
DHSTG =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Nsmdev01.corp.netsoftmate.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dhstg.corp.netsoftmate.com)
    )
  )

Destination details:
Database Name
dhstg
Hostname
Nsmstg01
Ip Address
172.16.110.16
OS
Linux
Version
x86_64
Datafile Location
/data1/diff/dhstg
Backup Location
/backup/rman_backup

Tns details:
dhstg_dup =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.110.16)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dhstg_dup)
    )
  )

Pre-requisites:

  • Oracle net configuration:
  • Both target and destination server should have tns entries.
  • Static listener registration on auxiliary site.
  • Service should be register on aux listener.
  • Password files from target database.
  • Sqlnet.ora should have correct parameters.
  • Target database should be running through spfile.
  • Check connectivity between target and destination server.
  • Target database instance should be in mount mode.
Steps on target (source) server:

1. Put tns entry of auxiliary database into target $ORACLE_HOME/network/admin directory

[oracle@Nsmdev01 admin]$ cd /data2/app/oracle/product/11.2.0/network/admin
[oracle@Nsmdev01 admin]$ vi tnsnames.ora

dhstg_dup =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.110.16)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dhstg_dup)
    )
  )


[[oracle@Nsmdev01 admin]$ tnsping dhstg_dup

Copyright (c) 1997, 2009, Oracle.  All rights reserved.

Used parameter files:
/data2/app/oracle/product/11.2.0/network/admin/sqlnet.ora


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.110.16)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = dhstg_dup)))
OK (0 msec)
2. Check database whether it is running in archive log mode.

SQL> select name,open_mode,log_mode from v$database;

NAME      OPEN_MODE            LOG_MODE
--------- -------------------- ------------
DHSTG    READ WRITE           NOARCHIVELOG

3. Check database is running from spfile. While duplicating database with different directory structure target database must be running with spfile.

SQL> select value from v$parameter where name='spfile';

VALUE
--------------------------------------------------------------------------------
/data2/app/oracle/product/11.2.0/dbs/spfiledhstg.ora


SQL> show parameter pfile

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      /data2/app/oracle/product/11.2                                                 .0/dbs/spfiledhstg.ora

4. Create pfile from spfile

SQL> create pfile='/backup/rman_backup/initdhstg.ora' from spfile;

File created.

5. Create password file.

[oracle@Nsmdev01 dbs]$ orapwd file=orapwdhstg password=oracle

6. Copy the password file and init file to destination $ORACLE_HOME/dbs directory using scp or ftp

[oracle@Nsmdev01 dbs]$ scp orapwdhstg oracle@172.16.110.16:/data2/app/oracle/product/11.2.0/dbs/
oracle@172.16.110.16's password:
orapwdhstg                                                                                                                                                        100% 1536     1.5KB/s   00:00

[oracle@Nsmdev01 rman_backup]$ pwd
/backup/rman_backup
[oracle@Nsmdev01 rman_backup]$ scp initdhstg.ora oracle@172.16.110.16:/data2/app/oracle/product/11.2.0/dbs/
oracle@172.16.110.16's password:
initdhstg.ora                                                                                                                                                     100%  861     0.8KB/s   00:00

7. Shutdown and start the instance in mount stage.

SQL> select name,open_mode from v$database;

NAME      OPEN_MODE
--------- --------------------
DHSTG    READ WRITE


SQL> shut immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.

Total System Global Area 1068937216 bytes

Variable Size             838864728 bytes
Database Buffers          222298112 bytes
Redo Buffers                5554176 bytes
Database mounted.
SQL> select name,open_mode from v$database;

NAME      OPEN_MODE
--------- --------------------
DHSTG    MOUNTED

Steps on destination server:

8. Put static listener entry into listener.ora file in $ORACLE_HOME/netwrok/admin directory.

oracle@Nsmstg01 admin]$ cd /data2/app/oracle/product/11.2.0/network/admin
[oracle@Nsmstg01 admin]$

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = dhstg_dup)
      (ORACLE_HOME = /data2/app/oracle/product/11.2.0)
      (SID_NAME = dhstg)
    )
  )
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.110.16)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )


 Here global_name is nothing but service name and sid_name is instance name
now reload the listener and check the services

9. put Tns entry for target(source) database in $ORACLE_HOME/network/admin directory

[oracle@Nsmstg01 admin]$ vi tnsnames.ora

DHSTG =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.110.18)(PORT = 1521))

10. Create the directory structure different from target (source) server.

[oracle@Nsmstg01 dhstg]$ mkdir -p /data1/diff/dhstg

11. Set the oracle sid and start the instance in nomount stage with pfile, here start the instance with pfile is must or else you will get error.

Solution: Work around for this is shutdown the target database and start in mount stage.
  • When you start the auxiliary instance with spfile.

Conclusion
In the above article, we have learned that Active Duplication using Rman utility with same database name and different directory structure, and our source Database is in noarchive log mode, and there are some vital things we need remember while performing active duplication of database running in no archive log mode, we have came a cross two errors and their work arounds.
