Configure Batch-only and Interactive-only AOS nodes in on-premises deployments

Community interest groups have now moved from Yammer to Microsoft Viva Engage. To join a Viva Engage community and take part in the latest discussions, fill out the Request access to Finance and Operations Viva Engage Community form and choose the community you want to join.

Important

This feature is supported starting in application update 10.0.12, Platform update 36.

This article explains how to configure your environment so that you can deploy batch-only and interactive-only Application Object Server (AOS) nodes.

To make this feature available, Microsoft has introduced two new Microsoft Azure Service Fabric node types. For batch-only AOS nodes, the new node type is BatchOnlyAOSNodeType. For interactive-only AOS nodes, the new node type is InteractiveOnlyAOSNodeType.

Note

The traditional deployment option, where an AOS node is interactive and is running batch jobs, is still supported and isn't affected by these changes.

Sizing

For sandbox environments, we recommend that you have at least two nodes of each type.

For production environments, there should be at least three nodes of each type.

New deployments

  1. When you're describing your configuration as explained in Set up and deploy on-premises environments, edit the configtemplate.xml file to enable the new node types. When you are done, the template should resemble the following example.

    <NodeType name="AOSNodeType" primary="false" namePrefix="AOS" purpose="AOS" disabled="true">
    <VMList>
        <VM name="aos1" ipAddress="" faultDomain="fd:/fd0" updateDomain="ud0" hasSSIS="false" />
        <VM name="aos2" ipAddress="" faultDomain="fd:/fd1" updateDomain="ud1" hasSSIS="false" />
        <VM name="aos3" ipAddress="" faultDomain="fd:/fd0" updateDomain="ud2" hasSSIS="false" />
    </VMList>
</NodeType>
<NodeType name="InteractiveOnlyAOSNodeType" primary="false" namePrefix="AOS" purpose="AOS" disabled="false">
    <VMList>
        <VM name="LBDE05FS1AOS01" ipAddress="192.168.5.51" faultDomain="fd:/fd0" updateDomain="ud0" hasSSIS="false" />
        <VM name="LBDE05FS1AOS02" ipAddress="192.168.5.52" faultDomain="fd:/fd1" updateDomain="ud1" hasSSIS="false" />
        <VM name="LBDE05FS1AOS03" ipAddress="192.168.5.53" faultDomain="fd:/fd0" updateDomain="ud2" hasSSIS="false" />
    </VMList>
</NodeType>
<NodeType name="BatchOnlyAOSNodeType" primary="false" namePrefix="AOS" purpose="AOS" disabled="false">
    <VMList>
        <VM name="LBDE05FS1AOS04" ipAddress="192.168.5.54" faultDomain="fd:/fd0" updateDomain="ud0" hasSSIS="false" />
        <VM name="LBDE05FS1AOS05" ipAddress="192.168.5.55" faultDomain="fd:/fd1" updateDomain="ud1" hasSSIS="false" />
        <VM name="LBDE05FS1AOS06" ipAddress="192.168.5.56" faultDomain="fd:/fd0" updateDomain="ud2" hasSSIS="false" />
    </VMList>
</NodeType>

  2. Follow the remaining instructions in Set up and deploy on-premises environments in the usual way.

Existing deployments

  1. Follow the instructions in Remove a node to remove all the nodes that you must remove.

  2. Follow the instructions in Add a node to add the new nodes.

  3. After you finish adding all the nodes, in Dynamics 365 Lifecycle Services, select Update Settings without changing any settings, to trigger an environment refresh. Alternatively, you can apply the latest hotfix.

    Important

    This step causes downtime. Therefore, ensure that your environment can be unavailable for some time.
