System failover
If a failover occurs, the length of an outage depends on several factors.
In the event of a failover, the length of your outage depends on whether or not the system can correctly redirect everything to the passive system, how long it takes for either the manual or automatic processes to run where you're switching DNS/IP addresses, and the time it takes to bring up the application servers in the passive-now-active system.
Therefore, you should ensure that you've set up everything correctly, as described in Configuring Jive for high-availability.
If you've set up the configuration so that all of the nodes correctly redirect to the passive system, here is an overview of what happens during a failover.
- Single data center
- Community users would not see any disruption.
- Multiple data center
- The length of disruption to end users would be between five and ten minutes, during which time, users would see a maintenance page when attempting to view community pages. Downtime depends, of course, on how fast you have set up database replication and how quickly your community administrators react to the outage of Data Center A.
