Description
|
|
~~~~~~~~~~~
|
|
|
|
:program:`named-journalprint` scans the contents of a zone journal file,
|
|
printing it in a human-readable form, or, optionally, converting it
|
|
to a different journal file format.
|
|
|
|
Journal files are automatically created by :iscman:`named` when changes are
|
|
made to dynamic zones (e.g., by :iscman:`nsupdate`). They record each addition
|
|
or deletion of a resource record, in binary format, allowing the changes
|
|
to be re-applied to the zone when the server is restarted after a
|
|
shutdown or crash. By default, the name of the journal file is formed by
|
|
appending the extension ``.jnl`` to the name of the corresponding zone
|
|
file.
|
|
|
|
:program:`named-journalprint` converts the contents of a given journal file
|
|
into a human-readable text format. Each line begins with ``add`` or ``del``,
|
|
to indicate whether the record was added or deleted, and continues with
|
|
the resource record in master-file format.
|
|
|
|
The ``-c`` (compact) option provides a mechanism to reduce the size of
|
|
a journal by removing (most/all) transactions prior to the specified
|
|
serial number. Note: this option *must not* be used while :iscman:`named` is
|
|
running, and can cause data loss if the zone file has not been updated
|
|
to contain the data being removed from the journal. Use with extreme caution.
|
|
|
|
The ``-x`` option causes additional data about the journal file to be
|
|
printed at the beginning of the output and before each group of changes.
|
|
|
|
The ``-u`` (upgrade) and ``-d`` (downgrade) options recreate the journal
|
|
file with a modified format version. The existing journal file is
|
|
replaced. ``-d`` writes out the journal in the format used by
|
|
versions of BIND up to 9.16.11; ``-u`` writes it out in the format used
|
|
by versions since 9.16.13. (9.16.12 is omitted due to a journal-formatting
|
|
bug in that release.) Note that these options *must not* be used while
|
|
:iscman:`named` is running.
