Per-junction allocation of worker threads for junctions

Use the pdadmin command to limit worker thread consumption on a per-junction basis. Specify hard and soft worker thread limits on a specific junction using the following options in the pdadmin server task create command.

• -l percent_value

  Set a value (percent) on the junction that defines the soft limit for consumption of worker threads. As in the global soft limit setting, this option causes warning messages to be displayed when the junction uses more worker threads than allowed by the setting.

• -L percent_value

  Set a value (percent) on the junction that defines the hard limit for consumption of worker threads. As in the global hard limit setting, this option causes warning messages to be displayed when the junction tries to use more worker threads than allowed by the setting. In addition, the user is sent a 503 Service Unavailable message.

pdadmin> server task webseald-<server-name> create-t tcp -h <host-name> -l 60 -L 80 jct-point

Per-junction settings always override the global settings in the WebSEAL configuration file. Ensure the settings on a specific junction do not adversely affect the policy that is established by the global settings.
