Configuring Admin Center

The adminCenter-1.0 feature enables the Liberty Admin Center, a web-based graphical interface for deploying, monitoring, and managing Liberty servers. After creating a Liberty JVM server, configure the server.xml file.

1. Open an editor on the server.xml file of the Liberty server, and configure the server for Admin Center. Add the adminCenter-1.0 feature to the feature manager.

   <featureManager>
      <feature>adminCenter-1.0</feature>
      <feature>websocket-1.1</feature>
   </featureManager>

   WebSocket provides a live view of the topology. Without the WebSocket feature, Admin Center web client periodically and frequently polls for changes.

2. Add the userid of all users of the Admin Center (SAF userid if registry), or add the RACF® group, to the built-in administrator role.

   <administrator-role>
      <user>username</user>
   </administrator-role>
   

   For more information about the built-in administrator role, see Mapping the administrator role for Liberty on z/OS
3. Optionally, give Admin Center access to write to server.xml by adding the following to server.xml:

   <remoteFileAccess>
       <writeDir>${server.config.dir}</writeDir>
   </remoteFileAccess>
   

   In the Admin Center you can see and edit server.xml, as well as any include files such as the CICS® installedApps.xml file.

   The design view lists and describes many other attributes of each element, providing a good way to understand the options available.

   Note:

   Some CICS augmented elements are not understood by a Liberty server and so those must be manually edited in the source view.

   Do not remove any of the essential CICS features, such as core-1.0. This disconnects the Liberty instance and the containing JVMSERVER resource.
