3.5. Database Link Plug-in Attributes (Chaining Attributes)

The database link plug-in attributes are also organized in an information tree, as shown in the following

diagram:

Figure 3.4 . Database Link Plug-in

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

plug-in node. T his section presents the additional attribute information for the three nodes marked in

bold in the cn=chaining database, cn=plugins, cn=config information tree in Figure 3.4,

“Database Link Plug-in”.

3.5 .1. Dat abase Link Att ributes under cn=config, cn=chaining dat abase , cn=plugins,

cn=config

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

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

3.5 .1.1 . nsActiveChainingComponents

This attribute lists the components using chaining. A component is any functional unit in the server. T he

value of this attribute overrides the value in the global configuration attribute. T o disable chaining on a

particular database instance, use the value None. T his attribute also allows the components used to

chain to be altered. By default, no components are allowed to chain, which explains why this attribute will

probably not appear in a list of cn=config, cn=chaining database, cn=config attributes, as

LDAP considers empty attributes to be non-existent.

Parameter Descript ion

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

cn=config

Valid Values Any valid component entry

Default Value None

Syntax DirectoryString

Example nsActiveChainingComponents: cn=uid

uniqueness, cn=plugins, cn=config

3.5 .1.2 . nsMaxResponseDelay

This error detection, performance-related attribute specifies the maximum amount of time it can take a

remote server to respond to an LDAP operation request made by a database link before an error is

suspected. Once this delay period has been met, the database link tests the connection with the remote

server.

Parameter Descript ion

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

cn=config

Valid Values Any valid delay period in seconds

Default Value 60 seconds

Syntax Integer

Example nsMaxResponseDelay: 60

3.5 .1.3. nsMaxTestResponse De lay
