Oracle Database is a database management system produced and marketed by Oracle Corporation. Oracle Database software have been translated into more than 60 languages.
The Oracle Backup plug-in allows protecting data stored and used by Oracle database, without stopping the service.
Before using Oracle plug-in you must configure the Oracle database engine first, and then add a specific user in a ORA_DBA group allowing him or her to run Oracle backup and restoration procedures. If you have already configured the plug-in, please refer to the next chapter.
In order to make “hot backups” without stopping an Oracle engine, it is necessary first to enable the ARCHIVELOG mode. If the database runs in the NOARCHIVELOG mode, then it will backed up in “cold” mode only (after stopping it).
To check which mode is active just now, use the following SQL operation:
SQL> select log_mode from sys.v$database;
If the value of LOG_MODE is NOARCHIVELOG, then you need to change it applying the following query:
SQL> alter database archivelog;
Note: To change the mode, your Oracle database instance must be mounted but not open. If it is open, you need to shutdown it, startup it with the mount option, enable the ARCHIVELOG mode, and then open the database for normal use:
SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database open;
If you use the Server Network edition of this software, it is possible to work with Oracle databases located on a workstation connected with the server via network. Follow these steps to set up this option properly:
Backups of local database can be created with any edition that has the Oracle plug-in available. The user account under which the program runs must have membership of the ORA_DBA group.
To add a user to the ORA_DBA group, you must perform these next operations:
After an Oracle engine has tuned properly, you can easily make backup or restoration tasks using Oracle databases as target data type.
To make a backup, do the following:
1. Select Backup task in New Task Wizard.
2. Select Oracle option on step 2 of New Task Wizard.
3. Select Oracle option for Backup.
Double click on Oracle option or click Oracle option and then OK.
4. Select destination for Backup.
Select option for backup, then click Oracle option or click Oracle option and then click Next.
5. Set up all other task parameters and click OK. Your backup is ready.
To restore Oracle Database from the backup, follow this instruction:
Oracle Database will be restored form saved state.
We are strongly recommending you to check all necessities several times before restoration, as this process can completely destroy any data collected or processed by database engine after the last backup. It seems reasonable to call for help of experienced personnel operating with Oracle (e.g. database administrator) every time a user feeling a need to restore some data from previous state.
