3.4. Database Plug-in Attributes

The database plug-in is also organized in an information tree, as shown in Figure 3.1, “Database Plug-

in”.

Figure 3.1. Database Plug-in

All plug-in technology used by the database instances is stored in the cn=ldbm database plug-in

node. This section presents the additional attribute information for each of the nodes in bold in the

cn=ldbm database, cn=plugins, cn=config information tree.

3.4 .1. Dat abase Attributes unde r cn=config, cn=ldbm database, cn=plugins, cn=config

This section covers global configuration attributes common to all instances are stored in the

cn=config, cn=ldbm database, cn=plugins, cn=config tree node.

3.4 .1.1 . nsLookT hroughLimit

This performance-related attribute specifies the maximum number of entries that the Directory Server will

check when examining candidate entries in response to a search request. The Directory Manager DN,

however, is, by default, unlimited and overrides any other settings specified here. It is worth noting that

binder-based resource limits work for this limit, which means that if a value for the operational attribute

nsLookThroughLimit is present in the entry as which a user binds, the default limit will be overridden.

Attempting to set a value that is not a number or is too big for a 32-bit signed integer returns an

LDAP_UNWILLING_T O_PERFORM error message with additional error information explaining the

problem.

Parameter Descript ion

Entry DN cn=config, cn=ldbm database, cn=plugins,

cn=config

Valid Range -1 to maximum 32-bit integer in entries (where -1

is unlimited)

Default Value 5000

Syntax Integer

Example nsLookT hroughLimit: 5000

3.4 .1.2 . nsslapd-idlistscanlimit

This performance-related attribute, present by default, specifies the number of entry IDs that are

searched during a search operation. 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.

It is advisable to keep the default value to improve search performance. For a more detailed explanation

of the effect of ID lists on search performance, refer to the "Managing Indexes" chapter in the Directory

Server Administrator's Guide.

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

Parameter Descript ion

Entry DN cn=config, cn=ldbm database, cn=plugins,
