Irresistable DB Duplicate on 11g

What I like in Oracle and especially it's database technology is ability to recognize user's needs and help them as much as possible in shortest possible period. This thought is not based on Oracle Support (aka Metalink) but on new features that comes with new releases leaving all good untouched. One of the most commented topic in database technology is RMAN and its duplicate command-ability to clone any Oracle database. However, I feel free to write another post on mentioned subject in a little different way: to create out of the box solution for any duplicate situation that might come in ad hock situation.

In 11g version this action can really be fully generalized regarding several improvements in which two are especially highlighted (as can be seen on previous picture):
  1. no need to connect to target database (all data are read from RMAN backup files directly). This gives ability to run DUPLICATE in any situation, with or without target database available!
  2. backup location may be anywhere you like (not necessary as it was in RMAN backup configuration on target database). If you look in mine topic (ORA-19870, ORA-19505, ORA-27041 on Windows 2008/2003) you might see some problems that DBA may face working with 10g on Windows. According this you'll appreciate this features a lot.

1. Configuration/environment

Here are the main data to understand next example:
  • The whole example is made on Windows 2008R2 x64 with Oracle 11gR2 x64 database.
  • Target database (one that is cloned) is "XE" and auxiliary (new replica) is "ORCL".
  • Target and auxiliary box are the same box.
  • ORACLE_HOME is the same what meant that directory structure for auxiliary datafiles are different.
  • Target database is in archive log with enabled flashback option.

2. Pre steps

Rather this steps is not necessary at all, I'll show them to ensure that the whole procedure exists only on shown actions.
This is why I have deleted all current backups, archived logs and backup sets, but in real case you do not have to do that. Shortly commands for that are:
C:\>SET ORACLE_SID=XE

rman target / nocatalog
crosscheck archivelog all;
crosscheck backup;
crosscheck backupset;
delete noprompt archivelog all;
delete noprompt backup;
delete noprompt backupset;

3. Backup target database

First we have to make full database backup with RMAN:
C:\>SET ORACLE_SID=XE

C:\>rman target / nocatalog
RMAN> backup database plus archivelog delete input;

4. Creating PIT point

To identified a time when to restore to, I'll create a table t1 with one record which will hold sysdate of the moment when the record was inserted. This will PIT point.
c:\>sqlplus "/ as sysdba"

SQL> create table t1 (a_date date);

Table created.

SQL> insert into t1 values (sysdate);

1 row created.

SQL> commit;

Commit complete.

SQL> select to_char(sysdate,'dd.mm.yyyy hh24:mi:ss') now_is from dual;

NOW_IS
-------------------
24.08.2010 21:03:16

SQL> drop table t1 cascade constraints;

Table dropped.

SQL> 
Now let us create some aditional archived log files that can cover this PIT:
SQL> alter system switch logfile;

System altered.

SQL> 

5. Backup previously created archived logs

Because in first backup I deleted all archived logs, all that happened later should be backed up additionally:
C:\>SET ORACLE_SID=XE

C:\>rman target / nocatalog
RMAN> backup archivelog all;

7. Copy backup files to different location

To prove that backup can be used from non default backup location, I'll copy all files from point 6. to new location "d:\Temp\all_backup_data>".

 Volume in drive D is New Volume
 Volume Serial Number is 1E97-BEEF

d:\Temp\all_backup_data>
In this way you can do the same when auxiliary box is not the same as target as well.

8. Pre cloning steps

Before we start duplicate, on Windows platform I have to:
  1. set new environment:
    d:\>SET ORACLE_SID=ORCL
    d:\>SET ORACLE_HOME=c:\oracle\product\11.2.0\db_1
    
  2. create %ORACLE_HOME%\DATABASE\initORCL.ora file with only one line content:
    db_name=ORCL  
    But I prefer to add two lines more:
    job_queue_processes=0
    compatible=11.1.0
    
    First one would stop any job that might want to start after clone (what we do not in many cases) and second will prevent "ORA-19726: cannot plug data [string] at level [string]" into database running at compatibility level string"
    All others init.ora entries for cloned database will be done automatically by RMAN duplicate command!
  3. create new ORCL instance by creating it through Windows service
    d:\>oradim -new -sid %ORACLE_SID% -intpwd newpwd -startmode M
    Instance created.
    
    d:\>
    
    If you are on Linux this step must be skipped.
  4. Start instance in nomount mode with previously create pfile.
    d:\>sqlplus "/ as sysdba"

9. RMAN duplicate

Now new instance is ready to be cloned. Important part is at the very beginning of starting RMAN:
c:\>rman auxiliary /
where you see that RMAN is not connected to target database as it was in the past! The rest of the RMAN script that will be used for cloning looks like:
RUN {
     ALLOCATE AUXILIARY CHANNEL aux1 type DISK;
     SET UNTIL TIME "to_date( '24.08.2010 21:03:16','dd.mm.yyyy hh24:mi:ss')";
     DUPLICATE DATABASE TO "ORCL"
       DB_FILE_NAME_CONVERT =('c:\oracle\product\oradata\XE\','C:\oracle\product\oradata\ORCL\')
       PFILE='c:\oracle\product\11.2.0\db_1\database\initORCL.ora'
       LOGFILE
         GROUP 1 ('C:\ORACLE\PRODUCT\ORADATA\ORCL\REDO01.LOG') SIZE 50M,
         GROUP 2 ('C:\ORACLE\PRODUCT\ORADATA\ORCL\REDO02.LOG') SIZE 50M,
         GROUP 3 ('C:\ORACLE\PRODUCT\ORADATA\ORCL\REDO03.LOG') SIZE 50M
       BACKUP LOCATION 'd:\Temp\all_backup_data'
     ;
     RELEASE CHANNEL aux1; 
} 
Where:
  • SET UNTIL TIME represent the same moment as sysdate previously inserted in table t1.
  • DB_FILE_NAME_CONVERT option remap directories
  • BACKUP LOCATION sets dynamically new backup location (different from original!)
Here the whole log of RMAN duplicate operation:

The End

In one of mine previous posts (Clone 11g ORACLE_HOME (different box, different path) on Linux) I have described how is easy to clone ORACLE_HOME in 11g on Linux. With this topic I think this subject is fully covered and may be use full for someone facing first time with it.

Cheers!
