Product Administration › Restore Data Aggregator

Restore Data Aggregator

You can restore the Data Aggregator information that you backed up. If Data Repository remains intact, you can restore only the Data Aggregator component.

You do not have to stop Data Aggregator before restoring. The backed up files can be dropped in the right directories even when Data Aggregator is running.

Note: You must have root or sudo privileges to perform this task.

Follow these steps:

1. Open a command prompt.
2. (Optional) In the situations where the Data Aggregator karaf service is not running, uninstall the existing Data Aggregator and reinstall it.
3. Run all of the following commands:

   cp DA_Backup/deploy_backup/*.* Data Aggregator installation directory/apache-karaf-2.3.0/deploy/
   cp DA_Backup/MIBDepot_backup/*.* Data Aggregator installation directory/apache-karaf-2.3.0/MIBDepot/
   cp DA_Backup/CustomDeviceType_backup/*.* Data Aggregator installation directory/apache-karaf-2.3.0/custom/devicetype/
   

   If prompted, overwrite the existing file.

   DA_Backup

   Specifies the directory path and name of the backup directory.

   Data Aggregator installation directory

   Specifies the Data Aggregator install directory.

   Default: /opt/IMDataAggregator

4. Wait for a few minutes for Data Aggregator to synchronize automatically with CA Performance Center. When the connections between the Data Aggregator and the Data Collector hosts are established, the Data Collector hosts resume polling.

   Data Aggregator is restored.

   Note: If you must restore Data Collector to a previous state, you can uninstall and reinstall Data Collector.
