Flush the Requests Queue on the Policy Server

Requests from SiteMinder agents are set to time out after a certain interval. However, the Policy Server continues to process all agent requests in the queue, even those requests that have timed out, in the order that they were received. The following situations can cause the queue to fill with agent requests faster than the Policy Server can process them:

• Network lag between the Policy Server and the policy store or user store databases
• Heavy loads on the policy store or user store databases
• Policy Server performance problems

When the Policy Server requests queue fills with agent requests, you can flush the timed-out agent requests from the queue, so that only the current agent requests remain. Only use this procedure in the following case:

1. Agent requests waiting in the Policy Server queue time out.
2. One or more Agents resend the timed-out requests, overfilling the queue.

Important! Do not use -flushrequests in normal operating conditions.

• To flush the requests queue on the Policy Server

1. Open a command prompt on the Policy Server.
2. Run the following command:

   smpolicysrv -flushrequests
   

   The request queue is flushed.

Note: On Windows systems, do not run the smpolicysrv command from a remote desktop or Terminal Services window. The smpolicysrv command depends on inter-process communications that do not work if you run the smpolicysrv process from a remote desktop or Terminal Services window.

Important! If you are running a SiteMinder utility or executable on Windows Server 2008, be sure to open the command–line window with Administrator permissions, even if you are logged into the system as an Administrator. For more information, see the release notes for your SiteMinder component.
