Windows Server Requirements
The virtual or physical Windows machine that hosts the IaaS components must meet conguration
requirements for the IaaS database, the IaaS server components, the IaaS Manager Service, and Distributed
Execution Managers.
The Installation Wizard runs a vRealize Automation prerequisite checker on all IaaS Windows servers to
ensure that they meet the conguration necessary for installation. In addition to the prerequisite checker,
address the following prerequisites separately.
n
As a best practice, place all IaaS Windows servers in the same domain.
n
Create or identify a domain account to use for installation, one that has administrator privileges on all
IaaS Windows servers.
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
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 workow
creation.
N 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 identier is copied to the clone, which causes
communication to fail. See “Error in Manager Service Communication,” on page 135.
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 “vRealize
Automation Port Requirements,” on page 25.
Alternatively, if site policies allow, you may disable rewalls between IaaS Windows servers and SQL
Server.
n
This release of vRealize Automation does not support SQL Server 2016 130 compatibility mode. If you
separately create an empty SQL Server 2016 database for use with IaaS, use 100 or 120 compatibility
mode.
If you create the database through a vRealize Automation installer, compatibility is already congured.
n
AlwaysOn Availability Group (AAG) is only supported with SQL Server 2016.
IaaS Web Service and Model Manager Server Requirements
Your environment must meet software and conguration prerequisites that support installation of the IaaS
server components.
Environment and Database Requirements for IaaS
Your host conguration and MS SQL database must meet the following requirements.
