4.3. Database Attributes under cn=NetscapeRoot, cn=ldbm

database, cn=plugins, cn=config and cn=UserRoot, cn=ldbm

database, cn=plugins, cn=config

The cn=NetscapeRoot and cn=UserRoot subtrees contain configuration data for, or the

definition of, the databases containing the o=NetscapeRoot and o=UserRoot suffixes,

respectively. The cn=NetscapeRoot subtree contains the configuration data used by the

Administration Server for authentication and all actions that cannot be performed through LDAP

(such as start/stop), and the cn=UserRoot subtree contains all the configuration data for the

user-defined database.

The cn=UserRoot subtree is called userRoot by default. However, this is not hard-coded and,

given the fact that there are going to be multiple database instances, this name is changed and

defined by the user as and when new databases are added. The following attributes are

common to both the cn=NetscapeRoot, cn=ldbm database, cn=plugins, cn=config and

cn=userRoot, cn=ldbm database, cn=plugins, cn=config subtrees.

4.3.1. nsslapd-cachesize

This performance tuning-related attribute specifies the cache size in terms of the entries it can

hold. However, it is simpler to limit by memory size only (as in Section 4.3.2,

“nsslapd-cachememsize”). Attempting to set a value that is not a number or is too big for a

32-bit signed integer returns an LDAP_UNWILLING_TO_PERFORM error message with additional

error information explaining the problem.

The server has to be restarted for changes to this attribute to go into effect.
