Configure a Liberty collective using the developer tools

Using the Liberty Utilities menu in the developer tools, we can create a collective controller or join a collective. Developer tools provides utilities for creating collective controllers or joining collectives. Note that creating a collective controller can be done only with WebSphere Application Server Network Deployment Liberty

Create a collective controller

1. Select:
   Servers > server (right-click) > 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 server.xml 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.

Join a collective controller

Note: We must have a collective controller available before a server can be added to a collective. Joining a collective can be done with WAS Liberty Base and WAS Liberty Core

1. Select:
   Servers > server (right-click) > Utilities > Join Collective

2. On the Join Collective page, specify the information of the collective controller to join.

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 server.xml was already updated to include the generated configuration file.
