• The modification action; that is, exactly how the directory was modified.
It is through the Retro Changelog Plug-in that the changes performed to the Directory Server are
accessed using searches to cn=changelog suffix.
3.6.1. nsslapd-changelogdir
This attribute specifies the name of the directory in which the changelog database is created the first
time the plug-in is run. By default, the database is stored with all the other databases under /var/
lib/dirsrv/slapd-instance_name/changelogdb.
NOTE
For performance reasons, store this database on a different physical disk.
The server has to be restarted for changes to this attribute to go into effect.
Parameter Description
Entry DN cn=Retro Changelog Plugin, cn=plugins,
cn=config
Valid Values Any valid path to the directory
Default Value None
Syntax DirectoryString
Example nsslapd-changelogdir: /var/lib/dirsrv/
slapd-instance_name/changelogdb
3.6.2. nsslapd-changelogmaxage (Max Changelog Age)
This attribute specifies the maximum age of any entry in the changelog. The changelog contains
a record for each directory modification and is used when synchronizing consumer servers. Each
record contains a timestamp. Any record with a timestamp that is older than the value specified in this
attribute is removed. If this attribute is absent, there is no age limit on changelog records, which is the
default behavior since this attribute is not present by default.
NOTE
Expired changelog records will not be removed if there is an agreement that has
fallen behind further than the maximum age.
Parameter Description
Entry DN cn=Retro Changelog Plugin, cn=plugins,
cn=config
Valid Range 0 (meaning that entries are not removed
according to their age) to the maximum 32 bit
integer value (2147483647)
Default Value 0
