Management database (MaxDB)

Backup and restore
  1. To create a backup of the management database, click Backup. The database is backed up in the "\OnSSI\Ocularis Recorder\sapdb\backup" folder.
  2. To restore a data backup, click Restore and select the required data backup.
Increase storage space (add volume)

If more storage space has to be made available to the administration database (MaxDB) because, for example, the event data is to remain available for an extended period, an additional volume can be added to the MaxDB. The default size of the MaxDB is 4 GB.

A maximum of four volumes can be added to the MaxDB.

This extension has no influence on the actual multimedia database (MaxDB).

  1. Enter the size [MB] of the additional storage space for the expansion of the MaxDB (minimum: 512 MB, maximum: 8000 MB).
  2. Click Add new volume. The additional storage space is available immediately under DISK000X in the MaxDB installation folder.
  3. Click the Refresh (3) button for an estimate of how long (in days) the space in the MaxDB will last at the current alarm rate. A reliable estimate can only be made if the system is running under normal load with reference to the alarm occurrence.
Cache

If a large number of events occurs with resulting high loading times, the MaxDB cache size can be increased.

However, this value should be selected carefully. Enlarging the cache is not useful if the computer does not actually have enough free RAM available.

The current cache size of the RAM reserved for the MaxDB is displayed. The actual size of the MaxDB is shown under “Current capacity utilization of the management database”.

The cache size of the MaxDB is an extremely system-critical parameter that should not be changed unless there are good reasons for it. The throughput is optimal if the complete database is kept in the cache.

  1. Enter a value in MB for the desired size, and click Adjust cache size.
