List Cluster Members
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 listClusterMembers.py sample demonstrates how to call the ClusterManager MBean from a Jython script to list all the cluster members in a collective.
- The ClusterManager MBean operation used:
The listClusterMembers sample script lists the members of a static cluster with the given cluster name. A connection is made to the collective controller located at the given host and port, and the request to list the cluster members is passed to the ClusterManager MBean.
First parameter The cluster name. --truststore The path to the truststore to be used when establishing a connection to the collective controller. --truststorePassword The password for the truststore specified by the --truststore parameter. --host The host name where the collective controller is running. --port The https port where the collective controller is listening. --user The user name to use when connecting to the collective controller. --password The password to use when connecting to the collective controller.
--help Displays help text. --debug Displays additional details when an error occurs.
