17.7 Restoring the Performance Management system
This subsection describes the procedure for using the backup file to restore Performance Management to its normal status when an error occurs in the Performance Management server.
- Note:
-
When restoring from a backup file, make sure that you use the same version of the product.
There are two methods for restoring Performance Management to its status before an error occurred.
-
For an error related to changes in the configuration
This procedure is used when an error occurs after changing the parameters or configuration, or when inconsistencies occur in the database storing the performance data or event data.
Restore the system by restoring, from the backup file, the definition information for the service where the error occurred, and the data model definition file for the performance data or event data.
-
For a serious error such as disk failure
This procedure is used when there is a possibility of wide-ranging damage to the Performance Management files due to a physical disk failure, or when the procedure for an error related to changes in the configuration fails to restore the Performance Management system.
Reinstall or set up Performance Management again.
Next, restore the system by restoring, from the backup file, all definition information, performance data, and event data for Performance Management.
- Point:
-
When changing the system configuration or updating the Performance Management version, it is recommended that a backup of the various definition information be obtained. Because performance data and event data are constantly updated, we recommend that you make regular backups in case of a disk failure. Performance Management provides commands for backing up performance data and event data.
For details on obtaining backups, see 9. Backing Up and Restoring Data.
