apply the existing journal file, if any, to the old version of the database before diffing it against the new version. then, append the diff to the end of the journal. this allows easy creation of a journal file with multiple deltas, by running named-makejournal successively.

Synopsis

~~~~~~~~

|
|
|
:program:`named-makejournal` [-hm] {origin} {oldfile} {newfile} [journal]
|

|
|
Description
|
|
~~~~~~~~~~~
|
|
|
|
:program:`named-makejournal` scans the contents of two zone files for
|
|
the domain specified by ``origin``, compares them, and writes the
|
|
differences into a journal file. The resulting journal file could
|
|
then be used by :iscman:`named` to load the zone and provide incremental
|
|
zone transfers.
|
|
|
|
Both ``oldfile`` and ``newfile`` must be successfully loadable as zone
|
|
databases, and ``newfile`` must have a higher SOA serial number than
|
|
``oldfile``.
|
|
|
|
If the optional argument ``journal`` is not specified, then the journal
|
|
file name will be formed by appending the extension ``.jnl`` to the
|
|
zone file name specified as ``oldfile``.
|
|
|
|
If the journal file already exists, then it will be applied to ``oldfile``
|
|
immediately after loading. The difference between the resulting zone and
|
|
the one in ``newfile`` will then be appended onto the end of the journal.
|
|
This allows creation of journal files with multiple transactions, by
|
|
running ``named-makejournal`` multiple times, updating ``newfile`` each
|
|
time.
