NAMED-JOURNALPRINT(1) BIND 9 NAMED-JOURNALPRINT(1)
NAME
named-journalprint - print zone journal in human-readable form
SYNOPSIS
named-journalprint [-c serial] [-dux] {journal}
DESCRIPTION
named-journalprint scans the contents of a zone journal file, printing
it in a human-readable form, or, optionally, converting it to a differ-
ent journal file format.
Journal files are automatically created by named when changes are made
to dynamic zones (e.g., by 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 shut-
down 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.
named-journalprint converts the contents of a given journal file into a
human-readable text format. Each line begins with add or del, to indi-
cate 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 se-
rial number. Note: this option must not be used while named is running,
and can cause data loss if the zone file has not been updated to con-
tain 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 named is running.
