To manage the size of the Configuration Management Database (CMDB), you can specify how long certain types of data are stored. You can specify storage length for data such as reports, managed computers, and event data. For example, if you experience poor performance when running reports, try purging your events or configure the event purging options to save less data.
The data that can be purged from the CMDB includes the following:
Snapshots older than a specified amount of time can be deleted.
The managed computers that have not communicated with Notification Server for longer than a specified amount of time
These can be deleted or set as retired. The CMDB is updated when the CMDB purging schedule is run.
Resource event data
Event data older than a specified amount of time can be deleted. You can optionally specify a maximum number of rows to retain. If the event data table reaches this size, new rows continue to be added until the next scheduled update. When the CMDB purging schedule runs, the table is trimmed back to its maximum size. The table is trimmed by removing the oldest rows, even if the oldest data has not been retained for the specified time.
You can have the same settings for all data classes, or you can set custom settings for some or all data classes. A custom setting for a data class overrides the global setting. If no custom setting is made for a data class, the global setting is used for that data class. The same CMDB purging schedule is used in all cases.
The CMDB purging schedule is a Windows schedule that you set when you install Notification Server. You cannot change it through the Symantec Management Console. If you want to make any changes, you can do so through the Windows Control Panel.
