Ability to submit requests in TPAM if Ticket System is unavailable
It's possible to configure the Ticket System properties in TPAM so that you can still make requests if the Ticket System goes down.
When the ticket system is down / under maintenance, go to the /admin interface, under System Status / Settings | Ticket Systems | Details tab.
Untick "Enable validation for this Ticket System", and tick "Allow provisional validation when system is disabled"
However over the blue question bubble for a description on this option:
"For Ticket Systems which validate against a database or web service you may enable "Provisional" validation. This is for times when the database is down or otherwise unavailable, and the Ticket System is marked as Disabled above. If the Ticket System is disabled and Provisional Validation is not checked then all ticket validation against this Ticket System will fail.
More information on configuring the Ticket System can be found in the TPAM Administrator Manual.
