Table 2-2 Database link configuration attributes (continued)
ValueAttributes
Lists the components using chaining. A component is any functional unit in the server.
The value of this attribute in the database link instance overrides the value in the
global configuration attribute. To disable chaining on a particular database instance,
use the value none. The default policy is not to allow chaining. For more information,
see “Chaining component operations”.
nsActiveChainingComponents
1
Controls whether referrals are returned by scoped searches. This attribute is for
optimizing the directory because returning referrals in response to scoped searches
is more efficient. Takes the values on or off. The default value is off.
nsReferralOnScopedSearch
Maximum number of times a request can be forwarded from one database link to
another. The default value is 10.
nsHopLimit
1
Can be both a global and instance attribute. This global configuration attribute is located in the cn=config,
cn=chaining database,cn=plugins,cn=config entry. The global attributes are dynamic, meaning any
changes made to them automatically take effect on all instances of the database link within the directory.
2.4.1.2.7 Database link configuration example
Suppose a server within the us.example.com domain contains the subtree l=Walla
Walla,ou=people,dc=example,dc=com on a database and that operation requests for the
l=Zanzibar,ou=people,dc=example,dc=com subtree should be chained to a different
server in the africa.example.com domain.
