Configuring Automatic Tape Cleaning For A Library - Oracle Secure Backup Installation And Configuration Manual

Adding Tape Devices to an Administrative Domain
Enter a value in the Minimum writable volumes field.

When Oracle Secure Backup scans tape devices for volumes to be moved, it looks
at this minimum writable volume threshold. If the minimum writable volume
threshold is nonzero, and if the number of writable volumes in that tape library is
less than this threshold, then Oracle Secure Backup creates a media movement job
for the full volumes even if their rotation policy does not require it. When this
happens, Oracle Secure Backup notes in the media movement job transcript that
volumes have been moved early.

Configuring Automatic Tape Cleaning for a Library

Oracle Secure Backup can automatically clean each tape drive in a tape library. A
cleaning cycle is initiated either when a tape drive reports that it needs cleaning or
when a specified usage time has elapsed.
Oracle Secure Backup checks for cleaning requirements when a cartridge is either
loaded into or unloaded from a tape drive. If at that time a cleaning is required, then
Oracle Secure Backup loads a cleaning cartridge, waits for the cleaning cycle to
complete, replaces the cleaning cartridge in its original storage element, and continues
with the requested load or unload.
To configure automatic cleaning for a tape library:
In the Auto clean list, select yes to enable automatic tape drive cleaning or no to

disable it. You can also manually request that a cleaning be performed whenever a
tape drive is not in use.
In the Clean interval (duration) field, enter a value and then select the cleaning
frequency from the adjacent list. This interval is the amount of time a tape drive is
used before a cleaning cycle is initiated. If automatic tape drive cleaning is
enabled, then this duration indicates the interval between cleaning cycles.
In the Clean using emptiest field, select one of these options:

If there are multiple cleaning tapes in a tape library, then Oracle Secure Backup
must decide which to use. If you do not otherwise specify, then Oracle Secure
Backup chooses the cleaning tape with the fewest number of cleaning cycles
remaining.
