The Pool Scrubber Parameters dialog box displays settings used by the Daily VOB Pool Scrubbing scheduled job. This job reclaims space in derived object and cleartext storage pools by deleting data containers in those pools. It does not affect source storage pools.
You can specify three parameters to constrain pool scrubbing:
- Maximum size: No scrubbing takes place unless the pool is at least this size.
- Reclaim size: Scrubbing stops when the pool falls below this size. However, if Maximum size is 0, this parameter is ignored.
- Age (hours): Data containers are deleted only if they have not been accessed for at least this number of hours. Containers least recently accessed are deleted first. A derived object container is deleted only if the reference count for the derived object is zero, indicating that the derived object is not used in any view. In this case, the derived object is deleted from the VOB database as well.
Click Default to restore any of these parameters to its default value.
- Alert command: You can specify a program to be run if the pool is still greater than the specified Maximum size when the scrubbing operation is finished. Enter the path to the program or click the browse button to browse for it.
