How to Connect Oracle Enterprise Manager 13cR2 with the Oracle Database Backup Service


In Oracle Enterprise Manager 13cR1, it was the first time when the Oracle Database Backup Service was integrated . In Release 2 the configuration menu was extended, a storage container can be defined now e.g. for a better organization and overview of the backups. This article shows you how to configure the Oracle Database Backup Service in Enterprise Manager 13cR2 and how to prepare a database for a cloud backup. All you need is the Oracle Database Backup Service, a trial works too.






 
Enter your domain and login information. Optional: Set a backup container. A backup container is an organiziation unit like a subdirectory on a server.


 

Configure the Database

Select the database which you want to backup to the Oracle cloud from the database target page. Configure Oracle Cloud Backup Service.


 

The first time when you run the configuration, you need to enter your host credentials for the host where the database is running which you want to configure. Use the username which has installed the database software, or you can use a named credential. Be sure that the server where the backup has to be configured has access to the internet.

After submit, a deployment procedure configures the Oracle Database Backup Service on the server. The Oracle Database Backup Service module will be installed on server.



 

The deployment procedure copies the tape library for the Oracle Database Backup Service into the $ORACLE_HOME/lib and creates a wallet in $ORACLE_HOME/dbs/opc with the cloud certificates. Bot components are required to use the service.

oracle@kestenholz:/u00/app/oracle/product/12.1.0.2/dbhome_1/lib/ [rdbms12102] lr libopc.so
-rwxr-----. 1 oracle oinstall 72062283 Oct 10 08:53 libopc.so


oracle@kestenholz:/u00/app/oracle/product/12.1.0.2/dbhome_1/dbs/opc/ [EMREPO] lr
total 4
-rw-rw-rw-. 1 oracle oinstall    0 Oct 10 08:53 cwallet.sso.lck
-rwxr-x---. 1 oracle oinstall 3101 Oct 10 08:53 cwallet.sso

The EM13c view after the successful deployment. To verify the configuration, press the Test Oracle Cloud Backup Button.

 

All backups into the Oracle Cloud have to be encrypted, the test run too.


 

Backup test succeeded.


 

Execute  RMAN Backup

Now you are able to backup an Oracle database with RMAN into the Oracle Cloud. Schedule a backup.


 

Schedule a customized backup


 

On the backup settings page, scroll down to set the encryption mode. You can choose between the wallet and the password method. As reminder, database backups with target Oracle Cloud have to be encrypted locally. Otherwise the backup job fails. Activate the checkbox for the password method and set/confirm the password. Next.

 

Select the Oracle Cloud as destination. Below you can see the used RMAN parameter. Oracle uses the file libopc.so like a tape driver. Next.

 

Schedule the execution. Next.

 

Now you can submit the job or use the syntax in the RMAN script box.


 






set encryption on for all tablespaces algorithm 'AES128' identified by '%PASSWORD' only;
backup device type sbt tag '%TAG' database;
backup device type sbt tag '%TAG' archivelog all not backed up;
run {
allocate channel oem_backup_sbt1 type 'SBT_TAPE' format '%d_%U' parms "SBT_LIBRARY=/u00/app/oracle/product/12.1.0.2/dbhome_1/lib/libopc.so ENV=(OPC_HOST=https://.storage.oraclecloud.com/v1/Storage-, OPC_WALLET='LOCATION=file:/u00/app/oracle/product/12.1.0.2/dbhome_1/dbs/opc CREDENTIAL_ALIAS=martin.berger@trivadis.com_')" maxpiecesize 1000 G;
backup tag '%TAG' current controlfile;
release channel oem_backup_sbt1;
}

The Backup Management Page shows the Oracle Cloud as Media

 

Conclusion

The Oracle Database Backup Service is fully integrated in the Oracle Enterprise Manager 13c and it works fine. The EM deploys you  the Oracle backup module on the target servers, once deployed, the configuration can be used for every other database which runs on the same target host as configured.
