Nsslapd-Changelogdir - Netscape DIRECTORY SERVER 6.2 Configuration Manual

• "nsslapd-cachememsize" on page 168
Note that the default values for the cache-related memory parameters (tuned for a
single backend replicated to a single consumer) are as follows:
nsslapd-cachesize : 3000
nsslapd-cachememsize : 10000000
When more backends are replicated or when you need to replicate one backend to
more than one consumers, consider tuning the parameters as below:
nsslapd-cachesize = 2000*#repl_agreements_initiated_from_this_server
nsslapd-cachememsize =
5000000*#repl_agreements_initiated_from_this_server

It is worth noting that two different types of change logs are maintained by
Directory Server. The first type, which is stored here and referred to as
changelog, is used by multi-master replication; the second change log, which is
actually a plug-in and referred to as retro changelog, is intended for use by Netscape
Meta Directory. See "Retro Changelog Plug-in" on page 142" of Chapter 3,
"Plug-in Implemented Server Functionality Reference" for further information
regarding the Retro Changelog plug-in. Multi-master replication changelog
attributes are presented in this section.

nsslapd-changelogdir

This required attribute specifies the name of the directory in which the change log
database will be created. Whenever a change log configuration entry is created, it
must contain a valid directory; otherwise, the operation will be rejected. The GUI
proposes by default that this database be stored under:
serverRoot/slapd-serverID/changelogdb
NOTE For performance reasons you will probably want to store this
database on a different physical disk.
