Updating Application Engine settings in a load balanced environment

You can update Application Engine settings in a load balanced Application Engine environment consisting of a load balancer or proxy device, several HTTP servers and several application server instances.

About this task

When several application server instances host the Application Engine application the goal is to provide to end-users the same work environment from every server instance. Application Engine uses a number of preference settings and configuration information to customize the Application Engine application for user needs. In order to provide a seamless work experience in an environment with multiple application server instances residing behind a load-balancer or proxy device it is important that each instance access the same configuration data.

The installer allows you to select the location of a shared configuration directory during the installation process. This shared configuration directory is used to store the files that contain preference settings and configuration information for the Application Engine application. A shared configuration directory allows you to have a single Application Engine instance with the same configuration information and preferences across multiple server instances. The process for managing settings by using a shared configuration directory is documented later in this section.

The shared configuration directory should ideally be placed on a highly available share or NFS exported directory that is accessible by all systems in the application server configuration.

Important: To be able to perform these tasks you must be a user assigned the Application Engine Administrator access role, and have copy/overwrite permissions on the directories shown later in this section on all nodes.

If you need to update your Application Engine Site Preferences you must refresh the configuration files on each node server.

To update Application Engine settings in a load balanced environment:

Procedure

  1. Make your Application Engine configuration changes.
    1. Sign into Application Engine as a user who is assigned the Application Engine Administrator access role.
      • Application Engine:
      • http://virtual_name:port_number/Workplace
    2. Click Admin.
    3. Click Site Preferences.
    4. Update your settings.
    5. Click Exit.
  2. Reload the Application Engine configuration files on each node.

    After changes are made you must reload the Application Engine configuration files on each node server.

    To load identical settings on all the nodes you must perform the following steps on each individual node server by logging in to the Application Engine instance running on the server.

    Restriction: Do not log in by using the load balancer URL.
    1. Sign into Application Engine as a user who is assigned the Application Engine Administrator access role.
    2. Use the following URL to sign in:
      • Application Engine:
      • http://node_server_name:port#/Workplace
    3. Click Admin.
    4. Click Site Preferences.
    5. Click Refresh.
    6. From the Refresh page, click Reload configuration files.
    7. Click Exit.

What to do next
