Areas[=storage-area[,...]]
Specifies the areas you want to recover. You can specify each
storage area by name or by the area's ID number.
You should use the Areas qualifier only if you have inconsistent
storage areas to recover. The default for the Areas qualifier
is all storage areas that must be recovered to make the database
consistent.
If the Areas qualifier is specified, a recovery operation by area
recovers until the storage areas being rolled forward are current
with the other storage areas, then recovery stops, regardless of
the time specified by the Until qualifier.
When the Areas qualifier is not specified or the Areas=*
qualifier is specified, Oracle RMU recovers all the storage areas
in the database to the time specified by the Until qualifier
or to the time of the last committed transaction in the .aij
file that can be applied. When the Areas qualifier is specified
without a value, Oracle RMU recovers to the earliest consistent
state only those storage areas that are not current with the
database root (.rdb) file of the database.
The Areas qualifier works in the following manner:
o If the Areas qualifier is specified without a value, Oracle
RMU automatically determines what areas are inconsistent
and recovers those areas. If an inconsistent area cannot
be recovered because it is at a higher transaction sequence
number (TSN) value than the database root file, the entire
database is recovered even if the Areas qualifier was
specified.
See the Oracle Rdb Guide to Database Maintenance for
information on TSNs.
o If the Areas qualifier is omitted or the Areas qualifier is
specified as Areas=*, the entire database (all storage areas)
is recovered.
o If the Areas qualifier is specified as Areas=(A1,A2,A3), only
areas A1, A2, and A3 are recovered until they are consistent.
If one of these areas is already consistent, or if an area is
at a higher TSN value than the database root file, the entire
database is recovered.
o If the Online qualifier is specified with the Areas qualifier
(as in the first three list items) and the end result is that
the entire database must be recovered, an error message is
generated because you can recover only individual areas by
using the Online qualifier, not the entire database.
You cannot use the Areas qualifier with the Just_Corrupt
qualifier because the Areas qualifier implies recovery for all
named areas and pages in those areas. (That is, use of the Just_
Corrupt qualifier with the Areas qualifier is redundant.)
The Areas qualifier can be used with indirect file references.
See the Indirect-Command-Files help entry for more information.
