After_Journal[=file-spec]
Noafter_Journal
NOTE
This qualifier is maintained for compatibility with versions
of Oracle Rdb prior to Version 6.0. You might find it more
useful to specify the Aij_Options qualifier, unless you are
only interested in creating extensible after-image journal
(.aij) files.
Specifies how Oracle RMU is to handle after-image journaling and
.aij file creation, using the following rules:
o If you specify the After_Journal qualifier and provide a file
specification, Oracle RMU enables after-image journaling and
creates a new extensible after-image journal (.aij) file for
the database.
o If you specify the After_Journal qualifier but do not
provide a file specification, Oracle RMU enables after-image
journaling and creates a new extensible .aij file for the
database with the same name as, but a different version number
from, the .aij file for the database root file being moved.
o If you specify the Noafter_Journal qualifier, Oracle RMU
disables after-image journaling and does not create a new
.aij file.
o If you do not specify an After_Journal, Noafter_Journal,
Aij_Options, or Noaij_Options qualifier, Oracle RMU retains
the original journal setting (enabled or disabled) and the
original .aij file state.
You can only specify one, or none, of the following after-image
journal qualifiers in a single RMU Move_Area command: After_
Journal, Noafter_Journal, Aij_Options, or Noaij_Options.
You cannot use the After_Journal qualifier to create fixed-size
.aij files; use the Aij_Options qualifier.
You can facilitate recovery by creating a new .aij file because a
single .aij file cannot be applied across a move area operation
that changes an area page size. A single .aij file cannot be
applied across a move operation because the move operation is
never recorded in the .aij file (and therefore the increase in
page size is also not journaled). Therefore, when you attempt
to recover the database, the original page size is used for
recovery purposes. So, if the .aij file contains database insert
transactions, these updates might have more free space associated
with them than is available on the original page size. This
results in an inability to recover the insert transaction, which
in turn results in a bugcheck and a corrupted database.
This qualifier is valid only when no users are attached to the
database and only when the root file is moved.
