Attributes in a media family are applied to a volume in the media family at volume creation time. The media family attributes are part of the volume's attributes. After data is first written to the volume, you cannot change the volume attributes other than by rewriting the volume. If you change the media family attributes, then these changes do not apply to any volumes that have already been created in this family.
Oracle Secure Backup includes a default content-managed media family named
RMAN-DEFAULT. You cannot delete or rename this media family, although you can reset any options except for the following:
chmf [ --writewindow/-w duration ] [ --retain/-r duration ] [ [ --vidunique/-u ] | [ --vidfile/-F vid-pathname ] | [ --viddefault/-d | [ --vidfamily/-f media-family-name ] ] [ [--inputcomment/-i ] | [ --comment/-c comment ] ] [ --contentmanaged/-C ] [ --append/-a ] [ --noappend/-A ] media-family-name...
Refer to "mkmf" for descriptions of options that are not included in this section.
Allows input of an optional comment for the media family. After you execute
obtool prompts you to enter the comment. Terminate the comment with a period (
.) on a line by itself.
Specifies information that you want to store with the media family. If you choose to embed blanks in the comment, then surround the comment with quotes.
Specifies the name of the media family that you want to change.
Example 2-24 creates a time-managed media family called
full_bkup. The write window for volumes in the volume is 7 days. Because the retention period is 28 days, a volume in the media family expires 35 days after Oracle Secure Backup first writes to it. The example then changes the retention period from 7 days to 10 days.
