In this self help discussion, I will explain how much downtime required for specific application service, when a new certificate is mapped and applied to SmartZone services.
How much time a service will take to come back, when a new certificate is mapped with SZ services?
Customer is renewing controller's wildcard CA cert as it is expiring soon (new cert has same domain name so just validity will change). They want to know below details to make sure there is no or minimum service impact:
1. What will be the service impact for each service and end clients which are already connected or may connect during service cert change.
2. How much time it will take for service to come to normal after changing all 4 certs to service mapping and hit OK?
Certificate update/install will restart subscriber mgmt, NBI and Web services. Customer can upload all these certificate at once and you can assume roughly 15 minutes (max) of downtime for services to recover
3. Do we need downtime if there is possibility for client disconnection or service impact?
Usually no downtime required for client connection but to avoid captive portal certificate errors, its better to update certificate during a maintenance window so that users will not wonder why they are getting certificate error.
4. How to check service status?
Go to SZ CLI >> Enable mode >> run "show service"
