2.3.2. cn=changelog5

Multi-master replication changelog configuration entries are stored under the cn=changelog5 entry.
The changelog behaves much like a database, and it has many of attributes also used by the ldbm
databases.

The primary cache-related memory attribute, nsslapd-cachememsize, has a default value of 10485760
bytes, which is 10 MB. This parameter is tuned for a single backend replicated to a single consumer.

When more backends are replicated or when one backend is replicated to more than one consumer,
tune the nsslapd-cachememsize so that its value is 5000000 times the number of replication
agreements initiated from the server (5000000 * no_of_repl_agreements).

The relationship between the values assigned to the nsslapd-dbcachesize and nsslapd-
cachememsize
parameters should be the same as the relationship that is described in the database
tuning section.

The cn=changelog5,cn=config entry is an instance of the extensibleObject object class.

NOTE

Two different types of changelogs are maintained by Directory Server. The first type, which is
stored here and referred to as the changelog, is used by multi-master replication; the second
changelog, which is actually a plug-in and referred to as the retro changelog, is for compatibility
with some legacy applications. See

Section 3.1.29, “Retro Changelog Plug-in”

for further

information about the Retro Changelog Plug-in.

2.3.2.1. nsslapd-changelogdir

This required attribute specifies the name of the directory in which the changelog database is created.
Whenever a changelog configuration entry is created, it must contain a valid directory; otherwise, the
operation is rejected. The GUI proposes by default that this database be stored in
/var/lib/dirsrv/slapd-instance_name/changelogdb.

WARNING

If the cn=changelog5 entry is removed, the directory specified in the nsslapd-changelogdir
parameter, including any subdirectories, are removed, with all of their contents.

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

cn=changelog5,cn=config

Valid Values

Any valid path to the directory storing the
changelog

Default Value

None

Syntax

DirectoryString

Example
