Oracle RMAN Channel Allocation
You can manually allocate RMAN channels by using the ALLOCATE CHANNEL command. This approach helps optimize backup operations and resource allocation. Specify the Veeam backup repository universal unique identifier (UUID) in the channel parameters to direct backup operations to the intended backup repository.
Important |
Keep in mind that the ALLOCATE CHANNEL command must be issued only within a RUN block for a specific backup operation. |
To manually allocate RMAN channels, do the following:
- Open the RUN block.
- Use the ALLOCATE CHANNEL command and specify the following parameters:
- Specify the channel ID. For example: ch1.
- Specify the SBT_TAPE option for the DEVICE TYPE parameter.
- Specify PARMS to define other parameters for the sbt_tape channel.
- Specify which media library must be used for this sbt_tape channel.
- [For Linux and Unix] Set the path to the libOracleRMANPlugin.so file as the SBT_LIBRARY.
- [For Microsoft Windows] Set the path to %PROGRAMFILES%\Veeam\VeeamPluginforOracleRMAN\OracleRMANPlugin.dll.
- Specify the Veeam backup repository UUID in the argument for the FORMAT parameter. You can find the required backup repository UUID in the rman_config.txt file or in log files.
- [For Linux and Unix] If you have exported Veeam Plug-in configuration files, run the following command to see the contents of the configuration file.
cat /tmp/rman_config.txt |
Alternatively, you can find the repository UUID in log files:
grep "received repos" /tmp/veeam_plugin_logs/oracle/OracleRMANConfigTool.log | tail |
- [For Microsoft Windows] If you have exported Veeam Plug-in configuration files, find the channel allocation definition in the configuration file.
Alternatively, you can find the repository UUID in log files. Go to the %\ProgramData\Veeam\Backup\RmanPluginLogs\SERV_NAME directory and search for "received repos id" in the OracleRMANConfigToolLib.log file.
- Use the BACKUP DATABASE command to create a database backup.
- [Optional] Use the RELEASE CHANNEL command. By default, RMAN automatically releases all channels when the RUN command terminates.
- Close the RUN block.
