This page describes parameters of the pool scrubber
operation. The Pool Scrubber Parameters window 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
the following 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
- 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 0, 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.
- Alert command
- You can specify an alert command. This causes the scrubber to run the
specified command (typically, a batch file) whenever it fails to scrub a pool
below its max-kbytes level. If you use a command built into the Windows shell
(for example, cd, del, dir,
or copy) instead of a batch file, you must open the shell
with cmd /c. For example:
-alert 'cmd /c cd \tmp & del *.*'
