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. + +See Also +~~~~~~~~ + +:iscman:`named(8) <named>`, :iscman:`nsupdate(1) <nsupdate>`, BIND 9 Administrator Reference Manual. |
