Stop Server sample script for Liberty Collectives using JRuby.

Description

In IBM WebSphere Application Server Network Deployment Version 8.5.5, Liberty profile has introduced the Liberty collective feature. Refer to information about collectives in the WebSphere Application Server Version 8.5.5 information center for more specifics.

The stopServer.rb sample demonstrates how to call the ServerCommands MBean from a jruby script to stop a collective server.

  • The ServerCommands MBean operation used:
    • stopServer

stopServer.rb script

The stopServer sample script demonstrates how to stop a collective member server with the given member host name, usr directory and member name. A connection is made to the collective controller located at the given host and https port, and the request to stop the member server is passed to the ServerCommands MBean.

Note that the server host name and collective controller host name do not need to be the same.

Server commands require remote execution and access (RXA). Before running this sample script, ensure the target system(s) are configured for remote access. For more information on the remote execution and access requirements and setup, refer to "Requirements for using Remote Execution and Access (RXA)" in the information center.

This sample can be installed onto runtime version 8.5.5.0.
