Setup CloneDB

 

With the help of Oracle’s in-built copy-on-write technology, a consistent backup of a database can be used to create a clone. The clone database accesses the backup data files in read-only mode. A PL/SQL procedure is used to create pointers to the backup data files. When a clone changes a block, or creates a new one, an unshared copy of the block is created. Multiple clones can share a single source database backup.

To setup a clone database, an Oracle supplied perl script can be used to generate three scripts: a pfile for the clone, a create control file script, and a rename data file script. These scripts can also be created manually. After running these scripts, the clone DB is available for use.

1.  Enable dNFS (optional)

Oracle direct NFS provides faster access to files stored on NFS. If your target backup, or clone data files, are on NFS and you want to avail of the faster access provided by dNFS, then use the following command to enable Oracle dNFS. Shut down all Oracle processes running from the Oracle home. (The documentation states that dNFS is required for CloneDB. However, as I have shown in Example 2 below, CloneDB works without dNFS.)

$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk dnfs_on
2.  Create Backup

Create a consistent image backup of the target database. If you cannot shutdown the target database, you can make a hot backup and apply archive logs to roll it forward.

$ rman target /
RMAN> startup mount
RMAN> backup as copy database format '/uo1/fra/db1/rman/clone/db1_%U';
3.  Generate Scripts

Setup environment variables and run perl script. Oracle home should point to the target database, and directories should be pre-created before runnning the perl script. The full path of the target database parameter file needs to be passed to the perl script (in the example below, it is /u01/oradata/clone1/initdb1.ora.) The MASTER_COPY_DIR should contain only backups of target database data files. You must remove all other files, including backups of control files and spfiles.

$ export MASTER_COPY_DIR='/uo1/fra/db1/rman/clone'
$ export CLONE_FILE_CREATE_DEST='/u01/oradata/clone1'
$ export CLONEDB_NAME=clone1

$ perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/install/clonedb.pl /u01/oradata/clone1/initdb1.ora crtdb.sql dbren.sql
4.  Create Clone

The perl script create three files in the CLONE_FILE_CREATE_DEST directory. Edit these files as needed, and make sure all directories required have been created. Oracle home should now point to the clone db. The generated script dbren.sql has a bug which will cause errors while trying to drop/create the TEMP table space. You can get around this by adding a temp file, as shown below.

SQL> @crtdb
SQL> @dbren
SQL> alter tablespace temp add tempfile '/u01/oradata/clone1/clone1_temp_1.dbf' size 256M;

Demo

The examples below use a Linux guest on Oracle VBox. Both the target and clone DBs run on the same host, and use the same Oracle home. The target backups and clone data files are on the local file system. Both examples share the same target database backup.

 

Example 1

After creating a consistent image backup of target database db1, manually create the three files needed for cloning. Create clone database cp1 and verify space usage.

— log into target database and create a consistent image backup

$ . oraenv
ORACLE_SID = [db1] ? db1
The Oracle base remains unchanged with value /u01/app/oracle
oracle@d12c1:/home/oracle/gs [db1]
$ rman target /
