Configuring a Liberty JVM server to use collectives
A collective is a set of Liberty servers in a single management domain. A collective consists of at least one Liberty server that is defined as a collective controller and any number of Liberty servers that are defined as collective members.
About this task
This task describes how to set up a Liberty collective that contains CICS Liberty JVM servers.
Collectives can span multiple hosts and architectures, meaning a collective can contain Liberty JVM servers in CICS. For more information about collectives, see Collective architecture.
Note: The following tasks focus on configuring Liberty JVM servers as controllers or members of the
collective. Any Liberty server can either host a collective as a controller, or join as a member.
For more information about configuring Liberty servers outside of CICS, see Setting up the server-management environment for Liberty by using collectives.
Procedure
- Configure a Liberty collective controller. For more information about configuring a Liberty JVM server as a collective controller, see Configuring a Liberty JVM server as a collective controller.
- Configure a Liberty server to join a collective as a member. For more information about configuring a Liberty JVM server as a collective member, see Configuring a Liberty JVM server as a collective member.
What to do next
- Configure the Admin Center on the collective controller to manage the collective from the Admin Center web application. For more information, see Configuring Admin Center.
- Configure the collective for highly available management capabilities. For more information, see Configuring Liberty collective replica sets.
- Configure a server cluster for application high availability and scale. For more information, see Setting up Liberty server clusters.
- Configure dynamic routing to route HTTP requests to applications in a collective dynamically. For more information, see Setting up dynamic routing for Liberty collectives.
- Configure health policies to manage the health of the collective. For more information, see Configuring health management for Liberty.
