Flush All Caches

The SiteMinder Cache Management dialog box provides a method for administrators to flush the contents of all caches. Flushing all caches may adversely affect the performance of a Web site, since all requests immediately following the cache flush must retrieve information from user directories and the policy store. However, this action may be necessary if critical user privileges and policy changes must go into effect immediately.

Note: This menu selection is only available to administrators who have either the Manage Users or Manage System and Domain Objects privileges. The Flush All button is only available for administrators with the Manage System and Domain Objects. If the menu selection is not available, the administrator account you used to log in does not have enough privileges to access the dialog box. For information about administrative privileges, see the Policy Design Guide guide.

If your configuration contains two policy servers pointing to one policy store, you can ensure that the primary (object cache) is included in the Flush All command. This causes both the primary and secondary caches to be rebuilt from the policy store. To enable this functionality, you must add the following entry to the registry:

Registry Name - FlushObjCache
Type - DWORD
Value - 0 (default)
Location - HKEY_LOCAL_MACHINE\SOFTWARE\Netegrity\SiteMinder\CurrentVersion\ObjectStore

To flush all caches

1. Log into the Policy Server User Interface.
2. From the menu bar of the SiteMinder Administration window, select Tools, Manage Cache.

   The the SiteMinder Cache Management dialog box opens.

3. In the All Caches group box, click Flush All.

   Note: The Flush All button in the All Caches group box is only enabled for administrators that have both the Manage Users and Manage the SiteMinder Objects privileges.

   The Policy Server and associated SiteMinder Agents flush all caches. This process will take up to twice the time specified by your policy server poll interval while the Policy Server synchronizes caches.

4. Click OK.

   The the SiteMinder Cache Management dialog box closes.
