Configuring a Liberty collective using the developer tools

Using the Liberty Utilities menu in the developer tools, you can create a collective controller or join a collective.

1. Creating a collective controller:
   Note: Creating a collective controller can be done only with the following editions:

   • WebSphere® Application Server Network Deployment Liberty
   • WebSphere Application Server for z/OS® Liberty
   1. In the Servers view, right-click your Liberty server, and select Utilities > Create Collective Controller.
   2. In the Keystore password field, type a password for your collective.
   3. Click Finish.
   Results:

   An information dialog appears after the collective configuration is complete. This dialog informs you that the server.xml file was already updated to include the generated configuration file. If there are instructions to add the configuration lines to the server.xml in the console output, they can be ignored. However, Administrative Security and other settings might still need to be configured within the included configuration file before any collective members can join.

2. Joining a collective controller:
   Note: You must have a collective controller available before a server can be added to a collective. Joining a collective can be done with the following editions:

   • WebSphere Application Server Liberty
   • WebSphere Application Server Liberty Core
   1. In the Servers view, right-click your Liberty server, and select Utilities > Join Collective.
   2. On the Join Collective page, specify the information of the collective controller you would like to join.
   3. In the Host field, type in the host name for the collective controller.
   4. In the Port field, type in the port number for the collective controller.
   5. In the User field, type in the user name for the collective controller.
   6. In the Password field, type in the password for the collective controller.
   7. In the Keystore password field, type the keystore password for the collective controller if encryption was used.
   8. Click Finish.
   Results:

   An information dialog appears after the collective configuration is complete. This dialog informs you that the server.xml file was already updated to include the generated configuration file. If there are instructions to add the configuration lines to the server.xml in the console output, they can be ignored.
