3.4.3. 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. 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 cn=userRoot database referenced can be any
user database.
The following attributes are common to both the cn=NetscapeRoot, cn=ldbm database,
cn=plugins, cn=config and the user database, such as cn=userRoot or cn=database_name,
cn=ldbm database, cn=plugins, cn=config subtrees.
3.4.3.1. nsslapd-cachesize
This attribute has been deprecated. To resize the entry cache, use nsslapd-cachememsize.
This performance tuning-related attribute specifies the cache size in terms of the number of entries
it can hold. However, this attribute is deprecated in favor of the nsslapd-cachememsize attribute,
Section 3.4.3.2,
which sets an absolute allocation of RAM for the entry cache size, as described in
"nsslapd-cachememsize".
Attempting to set a value that is not a number or is too big for a 32-bit signed integer (on 32-bit
systems) 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.
