Restart the server.
For information on restarting the server, refer to “Starting and Stopping the
Directory Server,” on page 31.
The retro change log is created in the directory tree under a special suffix
cn=changelog
.
The procedure for enabling the retro change log plug-in from Directory Server
Console is the same as for all Directory Server plug-ins. For information, refer to
“Enabling and Disabling Plug-Ins From the Server Console,” on page 454.
Trimming the Retro Change Log
The entries in the change log can be automatically removed after a specified period
of time. To configure the period of time after which entries are automatically
deleted from the change log, you must set the
nsslapd-changelogmaxage
configuration attribute in the
cn=Retro Changelog
Plugin,cn=plugins,cn=config
entry.
The
nsslapd-changelogmaxage
attribute is a single-valued attribute. Its syntax is
as follows:
nsslapd-changelogmaxage:
Integer timeUnit
where integer represents a number, and timeUnit can be one of the following:
s
for
seconds,
m
for minutes,
h
for hours,
d
for days, or
w
for weeks.
Note that there should be no space between the Integer and timeUnit variables. The
space in the syntax above is intended to show that the attribute value is composed
of two variable parts, not just one.
Example of
nsslapd-changelogmaxage
value:
nsslapd-changelogmaxage: 2d
Searching and Modifying the Retro Change Log
