Upgrading clustered runtimes to JGroups 3

To upgrade your runtime clusters and private runtime clouds from JGroups2 to JGroups 3, set the JGroups Clustered Library Version property on the Properties panel.

Before you begin

You must have the Runtime Management privilege to perform this task. If you have the Runtime Management Read Access privilege, you cannot perform the task.

About this task

Boomi recommends upgrading your runtime clusters and private runtime clouds to JGroups 3 because JGroups 3 provides better stability for clustered basic runtimes (basic runtimes that are used in runtime clusters and Clouds).
Note: JGroups 3 is the default for new clustered basic runtimes that are being installed on the Java 8 runtime cluster or runtime cloud installer.

Procedure

  1. Go to Manage > Runtime Management.

  2. Select the runtime cluster node or runtime cloud cluster from the list.

  3. In Settings & Configuration, click Properties.

    The Runtime cluster Properties panel opens.

  4. Click the Advanced tab.

  5. Select the JGroups Clustered Library Version property (-Dcom.boomi.container.clusterLibVersion) and click Add a Property.

  6. In the Property Value field, type 3.

  7. Click Save.

    Because changes to this property do not take effect until the runtime cluster or runtime cloud is restarted, you are prompted to restart. You have the option to restart now or restart later.

Next steps

After the runtime cluster or runtime cloud restarts, verify that this message shows up in its container logs:

INFO [com.boomi.container.cloudlet.cluster.ClusterManager <init>] Loading ClusterManager JGroups3ClusterManager

Note the number 3 in: “JGroups3ClusterManager”. If the number 3 is not there, the runtime cluster node or runtime cloud cluster was not upgraded.
