Considerations for installing multiple instances on a computer [AX 2012]

Updated: July 31, 2014

Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012

In a single environment, you can install multiple instances of Application Object Server (AOS) and the Microsoft Dynamics AX database.

You can install multiple instances of Microsoft Dynamics AX components on separate computers or on the same computer. AOS instances and databases cannot be shared among instances of Microsoft Dynamics AX.

Multiple Microsoft Dynamics AX instances are primarily used in development environments that support multiple customers.

Caution noteCaution

We do not support the installation of multiple versions of Microsoft Dynamics AX components on the same computer in a production environment.

The following table lists the considerations when you install a second instance of a component.

Component

Considerations

AOS

Each AOS instance is automatically assigned a number between 01 and 99. This number is displayed in the Programs and Features item in Control Panel.

We recommend that you create a group in Active Directory Domain Services to manage permissions for the AOS accounts. For more information, see Install an Application Object Server (AOS) instance.

Database

During initialization, you can import existing data into the database.

Components that require .NET Business Connector

You can install only one instance of .NET Business Connector on a computer. In an environment that has multiple AOS instances, use the Microsoft Dynamics AX Configuration utility to make sure that the instance of .NET Business Connector on the local computer connects to the correct AOS instance for the component that you are installing.

In the utility, in the Configuration Target list, select Business Connector (non-interactive use only). On the Connection tab, verify that the correct AOS instance is displayed.

For more information about how to use the Microsoft Dynamics AX Configuration utility, click the Help button in the utility.

Reporting Services extensions

You can install multiple instances of Microsoft SQL Server Reporting Services on the same computer. In this kind of deployment environment, each instance of Reporting Services is connected to an independent Microsoft Dynamics AX installation. You may want to install multiple instances of Reporting Services on the same computer to support development and production installations of Microsoft Dynamics AX, or to support multiple production installations of Microsoft Dynamics AX.

For information about how to install multiple instances of Reporting Services, see Install multiple instances of Reporting Services on the same computer (for use with Microsoft Dynamics AX).

Enterprise Portal

You can install multiple Enterprise Portal instances on the same computer. Portals can be configured to access the same or different Microsoft Dynamics AX AOS instances. For more information, see Install multiple Enterprise Portals on the same server.
