Upgrading JAMS Using a Primary-Failover Environment

Before You Begin

• Review the Upgrading JAMS V7 article for notes and additional requirements.
• Note the Log On As account that your JAMS Scheduler and JAMS Server services are running under, if they are not using LocalSystem. The upgrade sets the user for these services to LocalSystem.
• Create a maintenance window and allow currently running Jobs to complete. The maintenance window prevents future Jobs from executing during the upgrade. See Creating a Maintenance Window in JAMS.
• Create backups or snapshots of the following:
  • The JAMS Database.
  • The JAMS Scheduler Server, if it is running on a VM.
  • JAMS config files, such as JAMSHost.exe.config or JAMSScheduler.exe.config, that have been customized in C:\Program Files\MVPSI\JAMS\Scheduler. These changes will need to be reapplied after the upgrade.

Stop the JAMS Services on the Primary and Secondary Schedulers

1. On the Primary Scheduler, open the Windows Services application.
2. Complete the steps below for the three JAMS Services.
   1. Click the JAMS Executor service and select Stop. This will also stop the JAMS Scheduler service.
   2. Verify the service has stopped.
   3. Repeat these steps for the JAMS Server service and JAMS Scheduler service.
3. Repeat these steps on the Secondary Scheduler.

Upgrade the Primary Scheduler

1. Right-click the JAMS installer and select Run As Administrator.
2. Follow the prompts in the installer until the upgrade is complete.
   NOTE: If you clear any of the checkboxes in the JAMS installer, those components will be removed. It is recommended to not clear any checkboxes for the JAMS components.

3. Stop the three JAMS Services on the primary JAMS Scheduler.
4. Update the Log On As account that your JAMS Scheduler and JAMS Server services are running under, if they are not using LocalSystem.

Upgrade the Secondary Scheduler

1. Right-click the JAMS installer and select Run As Administrator.
2. Follow the prompts in the installer until the upgrade is complete.
   NOTE: If you clear any of the checkboxes in the JAMS installer, those components will be removed. It is recommended to not clear any checkboxes for the JAMS components.

3. Stop the three JAMS Services on the secondary JAMS Scheduler.
4. Update the Log On As account that your JAMS Scheduler and JAMS Server services are running under, if they are not using LocalSystem.

Restart the JAMS Services and Upgrade the Agents and Clients

1. Apply any JAMS config files, such as JAMSHost.exe.config or JAMSScheduler.exe.config, that have been customized. The files are located in C:\Program Files\MVPSI\JAMS\Scheduler.
2. Start the JAMS Services on the primary JAMS Scheduler to allow it to become the active JAMS Scheduler.
3. Start the three JAMS Services on the secondary JAMS Scheduler.
4. Verify the primary JAMS Scheduler is now active and the secondary JAMS Scheduler is now passive by doing the following:
   1. From the JAMS Client, click the About icon and select JAMS Servers.
      
   2. Click the Status tab.
   3. Ensure the server is listed in the correct mode (Running or Backup Mode). You may need to scroll down to see all of the information.
5. Run the installer on any remote Agents or Desktop Client to upgrade them.
6. Disable the maintenance window to resume normal operation. See Creating a Maintenance Window in JAMS.
