If using host-managed cleaning: do not configure system reserved slots for
cleaning cartridges. Host applications cannot access system reserved slots.
Cleaning cartridges must reside in storage slots controlled by the host application.

Determine the Number of Cleaning Cartridges
Cleaning cartridges clean tape drives. The number of cartridges required depends on
partitioning and your drive cleaning strategy.
Note:
Always use new cleaning cartridges. To the library, every newly imported
cleaning cartridge is new, with a usage count of zero. So if you load used
cleaning cartridges, you will not have an accurate count of the number of
remaining cleanings.
At least two cleaning cartridges should be available for drive cleaning. The total
number of cleaning cartridges in the library and where they need to reside depends on
your drive cleaning strategy and partitioning configuration.

If using library auto-cleaning or manual cleaning: Oracle recommends that
you provide two, new, LTO universal (
CU
) cleaning cartridges into reserved system
slots. The partitioning configuration does not affect this number.

If using host-managed cleaning: the number of cleaning cartridges required
depends on your partitioning configuration.
For a non-partitioned library, Oracle recommends that you provide two, new, LTO
universal (
CU
) cleaning cartridges placed into storage slots.
For a partitioned library, Oracle recommends that you provide two, new, LTO
universal (
CU
) cleaning cartridges per partition. A host application cannot access
drives or library slots that are not in the partition that it controls. So each partition
must contain cleaning media. For example, three partitions would require three
cleaning tapes at a minimum and six for best drive availability

Manage drive cleaning in one of three ways: library-managed, host-managed, or
manually.
Manage Expired Cleaning Cartridges
Remove expired cleaning cartridges from the library and replace them with a new
cartridge.
