Identifying the distributed directory servers to the proxy server

Edit online

You can identify the distributed directory servers to the proxy server using the instructions provided here.

Procedure

  1. Expand Proxy administration from the navigation area and click Manage back-end directory servers.
  2. Click Add.
  3. Enter the host name for ServerA in the Hostname field.
  4. Enter the port number for ServerA (for this example all servers use 389).
  5. Enter the number of connections that the proxy server can have with the back-end server in the Connection pool size field. The minimum value is 1 and the maximum value is 100. For this example, set the value to 5.
    Note:
    • Do not set the value in the Connection pool size field to be less than 5.
    • Number of connections to the back-end server should be less than or equal to the number of workers configured on the back-end server.
  6. Enter duration in seconds to schedule health check runs by the server.
    Note: This edit box is displayed only for proxy server with version 6.1 and above.
  7. In the Maximum pending client operations per connection field, enter a numeric value for the maximum pending client operations per connection. The ibm-slapdProxyMaxPendingOpsPerClient attribute of the ibm-slapdProxyBackendServer objectclass is associated with this field. This attribute is used to configure the threshold limit for pending requests from a client connection in a backend connection. The default value for the ibm-slapdProxyMaxPendingOpsPerClient attribute is 5. If a value of “0” is assigned to the ibm-slapdProxyMaxPendingOpsPerClient attribute, then number of client operations per connection that is pending can be unlimited.
    Note: In the Maximum pending client operations per connection field, only positive numeric values should be assigned. If negative values are assigned, an appropriate error message will be displayed.
  8. The authentication method for the back-end directory server is set to "Simple", by default. Verify that the Enable SSL encryption checkbox is not selected.
  9. Select the Enable health check outstanding limit check box to check the number of outstanding health check requests the server is waiting on.
  10. Enter a value for health check outstanding limit.
  11. Click Next.
  12. Specify the administrator DN, the DN of a member of the local administrator, or a member of a global admin group in the Bind DN field. For example, cn=root.
  13. Specify and confirm the administration password, in the Bind password fields. For example, secret.
  14. Click Finish.
  15. Repeat steps 2 through 10 for ServerB and ServerC.
  16. When you are finished, click Close to save your changes and return to the Introduction panel.
  17. Ensure that all the back-end servers are started.
    Note: If the proxy server cannot connect with one or more of the back-end servers at start up, the proxy server starts in configuration mode only. This is true unless you set up server groups. See Server groups.
