NAME

6       named-journalprint - print zone journal in human-readable form
7

SYNOPSIS

9       named-journalprint [-c serial] [-dux] {journal}
10

DESCRIPTION

12       named-journalprint  scans the contents of a zone journal file, printing
13       it in a human-readable form, or, optionally, converting it to a differ‐
14       ent journal file format.
15
16       Journal  files are automatically created by named when changes are made
17       to dynamic zones (e.g., by nsupdate).  They  record  each  addition  or
18       deletion  of  a resource record, in binary format, allowing the changes
19       to be re-applied to the zone when the server is restarted after a shut‐
20       down  or  crash.  By default, the name of the journal file is formed by
21       appending the extension .jnl to the  name  of  the  corresponding  zone
22       file.
23
24       named-journalprint converts the contents of a given journal file into a
25       human-readable text format. Each line begins with add or del, to  indi‐
26       cate  whether  the  record was added or deleted, and continues with the
27       resource record in master-file format.
28
29       The -c (compact) option provides a mechanism to reduce the  size  of  a
30       journal  by removing (most/all) transactions prior to the specified se‐
31       rial number. Note: this option must not be used while named is running,
32       and  can  cause data loss if the zone file has not been updated to con‐
33       tain the data being removed from the journal. Use with extreme caution.
34
35       The -x option causes additional data  about  the  journal  file  to  be
36       printed  at  the  beginning  of  the  output  and  before each group of
37       changes.
38
39       The -u (upgrade) and -d (downgrade) options recreate the  journal  file
40       with a modified format version.  The existing journal file is replaced.
41       -d writes out the journal in the format used by versions of BIND up  to
42       9.16.11; -u writes it out in the format used by versions since 9.16.13.
43       (9.16.12 is omitted due to a journal-formatting bug in  that  release.)
44       Note that these options must not be used while named is running.
