Media Family Commands
Commands in this category enable you to configure media families. A media family is
a named classification of backup volumes that share the following characteristics:
■ Volume ID sequence
■ Expiration policy
■ Write-allowed time period, which is called the volume write window
Write windows and expiration policies give you control over tape recycling. The
default for both settings is to allow tapes to be written to indefinitely and kept forever.
Setting limits enables you to overwrite tapes automatically at predetermined intervals.
Oracle Secure Backup is installed with a default content-managed media family
named RMAN-DEFAULT. If no media family specified in an RMAN job and no
matching backup storage selector exists, then RMAN uses RMAN-DEFAULT. You
cannot delete or rename this default media family, although you can change specified
attributes with chmf.
The obtool utility includes the following media family commands:
■ chmf
■ lsmf
■ mkmf
■ renmf
■ rmmf
