Hi,
The Operations Manager database is a single source of failure for the management group, so it can be made highly available using supported failover configurations such as SQL Server Always On Availability Groups or Failover Cluster Instances.
If you're hosting the database on a SQL Server cluster, replace computername with the virtual network name of the SQL cluster resource group. If the database is part of a SQL Always On Availability Group, replace computername\instancename
with the availability group listener name in the format of AvalabilityGroupListenerName,portNumber
.
