This topic describes how to configure an instance of Application Object Server (AOS) for Microsoft Dynamics AX as a stand-alone server by removing it from a load-balancing cluster. System administrators typically remove an AOS instance from a load-balancing cluster to perform maintenance.

We recommend that you complete the following tasks before you remove an AOS instance from load balancing.

  1. Determine whether the AOS instance is configured as a load balancer. If the server is a load balancer, and no other load balancer is available, client connections may fail when you take the server offline. For more information, see Create a load balancing cluster.

  2. Determine whether the AOS instance is a batch server. If the server is a batch server, and no other batch server is available, batch processes do not run. Verify that other servers in the environment are available for batch processing, or configure a different server for batch processing. For more information, see Configure an AOS instance as a batch server.

  3. Drain all users from the AOS instance that you want to remove from load balancing. For more information, see Drain users from an AOS.

  1. Connect to the AOS instance that you want to remove from load balancing. You can either change your client configuration so that it points to the AOS instance, or use the following command-line parameters: -aos2= Server_name and -loadbalance=0. For more information about how to change a client configuration, see Manage a client configuration. For more information about command-line parameters, see Client configuration commands.

  2. Click System administration > Common > Users > Online users.

  3. Verify that you are connected to the correct AOS instance and the AOS instance is not servicing any other clients.

  4. Click System administration > Setup > System > Cluster configuration.

  5. In the Max concurrent sessions field, enter 1.

  6. Verify that the Load balancer option is not selected.

  7. In the Map AOS instances to clusters section, select the AOS instance that you want to remove, and then click Remove. The AOS instance is now a stand-alone server. To delete the AOS instance from the environment, you must uninstall it by using Setup.
