Use the steps below to upgrade JAMS if you have a Primary-Failover Server Environment.

Since both the JAMS Scheduler Engines use the same database, you must first stop the JAMS Services (JAMS Executor, JAMS Scheduler, and JAMS Server) on the Primary and Failover Engines prior to updating.

Note: This also stops any currently executing Jobs. So stop these services at a time when you can have no Jobs running.

Upgrading the Primary Engine

Perform the upgrade on the Primary Engine. Once this is complete the JAMS Services and the JAMS SQL Database starts automatically.
Again, stop the JAMS Services on the Primary Engine since they were started after the actual upgrade.

Upgrading the Failover Engine

Perform the upgrade on the Failover Engine.
Stop the JAMS Services on the Failover Engine again since these services originally started after the upgrade.

Restarting the JAMS Services

Start the JAMS Services on the Primary Engine and wait a minute or two for the configuration to register with the database.
Start the JAMS Services on the Failover Engine. Everything should register with the proper failover configuration within approximately 3 minutes.
On the JAMS Client, go to About > JAMS Server and select the Status tab. You should see that each engine listed in the correct mode. It may be necessary to scroll down to view all the pertinent information.
