LDAP Data Source Pools

Requests from clients are distributed to an LDAP data source pool. One or more data sources are attached to the data source pool. The properties of a data source pool determine how client requests are routed to the different LDAP data sources that are attached to the pool. The following properties can be configured for an LDAP data source pool:


The algorithm used to determine when client requests should exhibit affinity to a single LDAP data source


The client affinity time-out duration


A description of the LDAP data source pool


A flag indicating whether or not consecutive requests from the same client should be directed to the same LDAP data source


The algorithm used to distribute operations over load-balanced LDAP data sources

For information about how to create and configure an LDAP data source pool, see Creating and Configuring LDAP Data Source Pools in Oracle Directory Server Enterprise Edition Administration Guide.
