Restore Changes to Logging in the app.config File
The upgrade process overwrites changes you make to logging in the configuration files. After you finish
an upgrade, you must restore any changes you made before the upgrade to the app.config file .
Enable Automatic Manager Service Failover After
Upgrade
Automatic Manager Service failover is disabled by default when you upgrade vRealize Automation.
Complete these steps to enable automatic Manager Service after upgrade.
Procedure
1 Open a command prompt as root on the vRealize Automation appliance.
2 Change directories to /usr/lib/vcac/tools/vami/commands.
3 To enable automatic Manager Service failover, run the following command.
python ./manager-service-automatic-failover ENABLE
To disable automatic failover throughout an IaaS deployment, run the following command.
python ./manager-service-automatic-failover DISABLE
About Automatic Manager Service Failover
You can configure the vRealize Automation IaaS Manager Service to automatically fail over to a backup if
the primary Manager Service stops.
Starting in vRealize Automation 7.3, you no longer need to manually start or stop the Manager Service on
each Windows server, to control which serves as primary or backup. Automatic Manager Service failover
is disabled by default when you upgrade IaaS with the Upgrade Shell Script or using the IaaS Installer
executable file.
When automatic failover is enabled, the Manager Service automatically starts on all Manager Service
hosts, including backups. The automatic failover feature allows the hosts to transparently monitor each
other and fail over when necessary, but the Windows service must be running on all hosts.
Note You are not required to use automatic failover. You may disable it and continue to manually start
and stop the Windows service to control which host serves as primary or backup. If you take the manual
failover approach, you must only start the service on one host at a time. With automatic failover disabled,
simultaneously running the service on multiple IaaS servers makes vRealize Automation unusable.
Do not attempt to selectively enable or disable automatic failover. Automatic failover must always be
synchronized as on or off, across every Manager Service host in an IaaS deployment.
