Passwords that contain special characters might be accepted when you assign them, but cause failures
when you perform operations such as saving endpoints or when the machine attempts to join the
vRealize Automation cluster.
Windows Server Requirements
The virtual or physical Windows machine that hosts the IaaS components must meet configuration
requirements for the IaaS database, the IaaS server components, the IaaS Manager Service, and
Distributed Execution Managers.
As a best practice, all servers should be in the same domain.
The Installation Wizard runs the vRealize Automation prerequisite checker on all Windows servers before
starting the installation process to ensure that the servers meet all necessary configurations.
IaaS Database Server Requirements
The Windows server that hosts the vRealize Automation IaaS SQL Server database must meet certain
prerequisites.
The requirements apply whether you run the Installation Wizard or the legacy setup_vrealize-
automation-appliance-URL.exe installer and select the database role for installation. The
prerequisites also apply if you separately create an empty SQL Server database for use with IaaS.
n
Use a supported SQL Server version from the vRealize Automation Support Matrix.
n
Configure SQL Server on port 1433, the default. Do not use a non-default port.
n
Enable TCP/IP protocol for SQL Server.
n
Enable the Distributed Transaction Coordinator (DTC) service on all IaaS Windows servers and the
machine that hosts SQL Server. IaaS uses DTC for database transactions and actions such as
workflow creation.
Note If you clone a machine to make an IaaS Windows server, install DTC on the clone after
cloning. If you clone a machine that already has DTC, its unique identifier is copied to the clone,
which causes communication to fail. See Error in Manager Service Communication.
For more about DTC enablement, see VMware Knowledge Base article 2038943.
n
Open ports between all IaaS Windows servers and the machine that hosts SQL Server. See Port
Requirements.
Alternatively, if site policies allow, you may disable firewalls between IaaS Windows servers and SQL
Server.
IaaS Web Service and Model Manager Server Requirements
Your environment must meet software and configuration prerequisites that support installation of the IaaS
server components.
