To Configure the Saturation Algorithm for Load Balancing

For a description of the saturation algorithm, see Saturation Algorithm for Load Balancing in Oracle Fusion Middleware Reference for Oracle Directory Server Enterprise Edition.

In this example, the data source ds-1 performs the majority of bind operations but does not perform any other types of operations. The three data sources are configured with the following weights :

• ds-1 is configured with weight 3 for bind operations and is disabled for all other types of operations.

• ds-2 is configured with weight 2 for all operations.

• ds-3 is configured with weight 1 for all operations.

You can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help.

Before You Begin

Ensure that you have a data source pool with at least three attached data sources. For information about how to create data sources and data source pools, see Creating LDAP Data Views.

1. Configure the data source pool to use the saturation algorithm for load balancing.

   $ dpconf set-ldap-data-source-pool-prop -h host -p port pool-name \ load-balancing-algorithm:saturation

2. Configure the properties of the first data source.

   $ dpconf set-attached-ldap-data-source-prop -h host -p port pool-name ds-1 \ add-weight:disabled bind-weight:3 compare-weight:disabled delete-weight:disabled \ modify-dn-weight:disabled modify-weight:disabled search-weight:disabled

3. Configure the properties of the second data source.

   $ dpconf set-attached-ldap-data-source-prop -h host -p port pool-name ds-2 \ add-weight:2 bind-weight:2 compare-weight:2 delete-weight:2 modify-dn-weight:2 \ modify-weight:2 search-weight:2

4. Configure the properties of the third data source.

   $ dpconf set-attached-ldap-data-source-prop -h host -p port pool-name ds-3 \ add-weight:1 bind-weight:1 compare-weight:1 delete-weight:1 modify-dn-weight:1 \ modify-weight:1 search-weight:1

5. Compare the key parameters of the attached data sources.

   $ dpconf list-attached-ldap-data-sources -h host -p port -v pool-name SRC_NAME add-weight bind-weight compare-weight delete-weight -------- ---------- ----------- -------------- ------------- ds-1 disabled 3 disabled disabled ds-2 2 2 2 2 ds-3 1 1 1 1 modify-dn-weight modify-weight search-weight ---------------- ------------- ------------- disabled disabled disabled 2 2 2 1 1 1

6. Restart the instance of Directory Proxy Server.

   $ dpadm restart instance-path
