Configuring LDAP performance settings on the WebSphere Application Server

To minimize the impact on performance when accessing an LDAP server, assign performance settings to the IBM® WebSphere® Application Server.

About this task

Configure context pools to minimize the impact on performance by adding opened connections and contexts to internally maintained pools and reusing them.

Procedure

  1. Log on to the WebSphere Integrated Solutions console that manages the SIP Proxy/Registrar server as the WebSphere administrator.
  2. Click Security > Global security.
  3. In the User account repository section, click Configure.
  4. In the Repositories in the realm table, click the Repository identifier.
  5. In the Additional properties section, click Performance.
  6. Select the Limit search time check box.
  7. In the Milliseconds field, type 30,000.
  8. In the Context pool section, in the Initial size field, specify 10.
  9. In the Preferred size field, specify 10.
  10. In the Context pool section, in the Maximum size field, specify 20. Each context is associated with one socket connection.
  11. Select the Context pool times out check box.
  12. In the Seconds field, specify the number of seconds to keep the idle connections in the context pool.
    • If you have an idle connection time-out set in the LDAP server, specify a smaller value in the Seconds field. For example, if the idle connection time-out on the LDAP server is set to 1 hour (3600 seconds), specify 3500 (seconds) in this field.
    • If there is a firewall between the WebSphere Application Server and the LDAP server, specify a value that is smaller than both the firewall's inactivity time-out setting and the LDAP server's idle connections time-out setting.
    • If the LDAP server is fronted by a load balancer, specify a value that is smaller than both the load balancer's inactivity time-out setting and the LDAP server's idle connections time-out setting.
  13. Click OK.
  14. Save the change to the master configuration by clicking the Save link in the "Messages" box at the beginning of the page.
