Session cache reference
Use the Cluster Configuration management page to administer cluster support for the appliance.
- Worker threads
- The number of worker threads that handle the server requests. At a minimum, use a number that is greater than the maximum number of clients.
- Maximum session lifetime
- The maximum lifetime in seconds for each session. Use a value greater
than the maximum lifetime of all clients. That is, use a value greater
than the maximum [session] timeout value that the
WebSEAL clients use.
For more information about the [session] timeout configuration entry, see the reference topics for the Web Reverse Stanza Proxy in the Knowledge Center.
- Client grace period
- The grace period in seconds that a client has available to restart and
register an interest in the session again before the session is removed
from the session cache. This period gives the client a chance to restart
without losing the session from the server.
Use a similar value to the idle timeout value for the session on the client. That is, use a value similar to the [session] inactive-timeout value that is set in the client Web Reverse Proxy configuration.
For more information about the [session] inactive-timeout configuration entry, see the reference topics for the Web Reverse Stanza Proxy in the Knowledge Center.
- Support internal clients only
- Indicates that only internal clients can use the distributed session
cache. Notes:
- The current version supports internal clients only.
- If this option is selected, the remaining fields are disabled.
-
Clients can be turned off. For more information about failover events, search for the Options for handling session failover events topic in the Administering topics in the Knowledge Center. For more information about configuration properties, see Advanced configuration properties.
- Support internal and external clients
- Indicates that both internal and external clients can use the
distributed session cache.Note: Support for external clients is not available in the current version.
- Port
- The port on which external clients can communicate with the session cache. This field is mandatory if you enable support for internal and external clients.
- Enable SSL
- If selected, the distributed session cache uses secure communication
with its clients. Note: If you enable SSL, you must also configure the Keyfile.
- Keyfile
- Lists the existing keyfiles on the appliance. These keyfiles are managed
from the SSL certificates page. You can click the SSL
Certificates link on the right to go to that
page.Note: If you want to share the key files across the cluster, you must go to the SSL Certificates page and select the Replicate with Cluster check box.
- Label
- Lists the certificate labels in the selected keyfile. This field is disabled if a keyfile is not selected.
- Trace level
-
Specifies the trace level for the DSC with an integer (0 - 9). 0 indicates that trace is disabled. 9 indicates the maximum trace level.
Note: The trace level setting is not a part of the cluster policy. So this setting is not replicated across the cluster and is not persistent across firmware updates. The trace messages are sent to the log file for the DSC.
