Backup (ideally on a test machine) produced.All examples assume that an application to the database using operating systemauthenticationis possible. For this purpose, the following requirements must be met:•

It must be given to the operating system user access to the database server, under is installed to the database. Typically, this user is "oracle". This User needs of the "dba" group members.• At least the environment variables ORACLE_HOME1 and ORACLE_SID set and$ ORACLE_HOME / bin to be included in the PATHThe instance name of the database (ORACLE_SID =) can be, if not known,determined from the PMON process.He stands at the end of the process name, starting behind "ora_pmon_":[Oracle @ c-db-17 (db11gR2 ORCL1)] $ ps-ef | grep pmonoracle36061 0 11:14?00:00:00 ora_pmon_orcl1Before function test but should in any case an evaluation of the past to the database backups are performed. Because if no valid backup already created, there is no needof

Restore test anyway.The following SQL statement evaluates the backups from the last seven days (if thederivative inControl file is sufficiently large). The query returns no rows or can be found in the"STATUS" columnseldom or not the value of "COMPLETED", then in any case of a serious problem andthe backupLack of proper backups to go.1For OFA-compliant installations / u01/app/oracle/product/11.1.0/db_1 for version

6.62 Validate a backup Advantage of validating is that it causes very little effort compared to duplicate and noTest machine must be installed. The disadvantage, however, is that no genuine

Restore / Recovery takes place andso that the final safety regarding the usability of backups is not given.Backups can be both logical (restore ... preview ) And physically (restore ... validate ) Are validated.2.1 Option 1: Logical Validation For a logical validating RMAN lists only the backup files in question from himavailable metadata (control file, RMAN Catalog) on. He does not check whether thesefiles actually availableor are intact.The following example successfully restore a backup created on 12.05.2011 at 11:30clock validated.Oracle_RMAN_11g_Backuptest_ASPICON_Whitepaper_2012-03-28, copyright byASPICON all rights reservedPage 3/20

In both cases, the production database is open and fully usable during the test.2.3 Variant 3: Duplicating a Database from a Backup Unlike the pure validating the installation of a test server is recommended for aduplicate. InPrinciple can be applied also copy it to the production server, however, the adaptationefforthere considerably higher and, especially for beginners, the risk of serious damage totheProduction database rather high.It is recommended that the productive largely identical to install the test system. Thatis, up tonecessary differences in network and system configuration should be the samedatabase version (including possibly rehearsed patches) and the same directory structure as are used in the production system.2.3.1 Installing the Oracle Software On the test server the same version of the database is to be installed, which is also on

the production server in use.Attuned to install additional patches are also necessary on the production side. Duringthe installation,especially the production of the pre-installation requirements, a look in the "Quick DatabaseInstallation Guide ". It is recommended that the operating environment accordingly bysetting the variablesORACLE_BASE, ORACLE_HOME and ORACLE_SID and recording of the $ORACLE_HOME / bin in the PATH prepare.ORACLE_BASE should be set for an OFA-compliant installation /

u01/app/oracle. For the other Variable values is referred to the introduction to this paper. To change the settings to persistmake, should the respective variable, depending on shell, inoracle / .bash_profile or oracle / .profile be registered.



At this point we can already make the TNS entry for the production database, as theywhile later Duplicate must be referenced as the "target". We assign here the net service name"prod". Useeither the netca or wear with a text editor the following in the tnsnames.ora file

2.3.2 Providing the productive backups As for duplicating a database, not the database itself, but on database backupsuse is made, the backup of the production database must be on the test server (bestread only) availableare made. In one example, provided by the c-db-17 NFS share was added to theBackup Filesmounted on / backup / oracle.2.3.3 Duplicate the production database

In contrast to previous versions starting with Oracle 11g has the spfile no longer separately restored and adaptedare. This step can now directly under the "duplicate" by specifying "spfile" done withare. Differences in the directory structure or data storage to the production server or other required changes in the spfile of the target database may on appropriate information(spfile set ...)



be considered.However, before cloning nor the audit_dump_dest directory to create, as well as thestill to 11.2not part of the ADR:[Oracle @ c-db-18 (clone db11gR2)] $ mkdir -p/u01/app/oracle/admin/clone/adump

All other Dumpverzeichnisse be automatically during the first startup of the database.Since an incomplete recovery is performed in the course of duplicating the "until"clause must be aappropriate video value to be specified. To make a current copy as possible, therecovery shoulduntil the last Archivelogsequence included in the backup.

1 Preparations The following tutorial describes the steps required to create a with the Oracle

Recovery Manager (RMAN) created backup of a production database back playing in a clone database.For this purpose, a decoupled from the production environment test system is needed,on the one ORACLE

Database 10g is installed. The following scripts are created for Oracle Database 10g,as the onlycame with version 10g available command "CLONE DATABASE". In principle, itshould, however, alsoVersion 9i work.It is recommended that the test system is largely the same installed. That is, up to thenecessaryDifferences in network and system configuration should be the same Oracle

version (including anyrehearsed patches) be installed as in the productive system.

In the following script called [ORACLE_SID] the unique database system identifier (SID) of theProductive system. If the data is imported into another directory than the productionsystem, it is before init [ORACLE_SID]. ora file to adjust accordingly.It is recommended to make a backup on a network drive on the test computer available so that aaccidental deletion is not possible. This can be accessed via NFS and other network file systemsare. More information can be found in the NFS Manual.

2 Step 1: Install the Oracle software and create the Database environment



To a normal Oracle database installation must be performed without generating. Infollowing is the installation path as/ U01/app/oracle /accepted. Then the directories for the database files are in a shell of User "oracle" create (shell scripts are given for a POSIX shell, such as bash or sh):

#the ORACLE HOME directory (ORACLE_HOME)export ORACLE_HOME = / u01/app/oracle/product/10.2/dbmkdir-p $ {ORACLE_HOME}#Directory database and alert logsmkdir-p / u01/app/oracle/admin / [ORACLE_SID] / bdump#Directory to store core dumpsmkdir-p / u01/app/oracle/admin / [ORACLE_SID] / cdump#Directory for user dumpsmkdir-p / u01/app/oracle/admin / [ORACLE_SID] / udump Next, a TNSAlias be applied. The following example uses the alias 'CLONE' todatabase'Prod.world' created. To the $ {ORACLE_HOME} / network / admin directory is /tnsnames.orato edit and add the following entry:CLONE = (

If this is not the case, in the meta-link listed in the Annex Notes notes to be read additional procedures.4

Step 3: Start the database without a database to mount. This is a shell of the user oracle sqlplus to start the tool:export ORACLE_SID = prodsqlplus "sys / as sysdba <sys_passwd>"<sys_passwd> be replaced by the valid password.Then the database in nomount mode starts at sqlplus prompt:sqlplus> startup nomountASPICON GmbH> test with Oracle RMAN backup for Oracle Database 10gCopyright 2006 by ASPICON GmbH, Chemnitz, All Rights Reserved

and then executes the following script at the RMAN prompt:RMAN> run {allocate channel c1 type disk;restore controlfile until time"To_date ('13-12-2005 15:34:38 ',' DD-MM-YYYY HH24: MI: SS ')";

release channel c1;}The first command opens a channel to the backup medium (in this example'disk'). The secondCommand initiates a restore of the control and SPFILE specified at the date DDMM-YYYY HH24: MI: SSThe last command closes the channel to the backup medium.6 Step 5: Switch the database in the 'mount' mode To do this in sqlplus as commandsqlplus> alter database mount;are executed.ASPICON GmbH> test with Oracle RMAN backup for Oracle Database 10gCopyright 2006 by ASPICON GmbH, Chemnitz, All Rights Reserved

The return data for control and database files have to be identical

be selected. The above script does the data from the last full backup file back.8 Step 7: Play back the archive log files Now just fill in the archive log files, which are still missing transactions since the lastfull backup prior to the desired date of recovery included. From thesestarting from the database files of the state at exactly the time givenare produced.
