Enabling Hazelcast

In the default domain configuration of Payara, Hazelcast is not enabled.

It can be enabled either through the Admin Console, or by using a command line asadmin command.

Enabling Hazelcast through the Admin Console

From the Admin Console home:

  1. Select the instance’s configuration from the page tree:

    Payara Server Page Tree
  2. Click the "Hazelcast" button to view the "Hazelcast Configuration" page:

    Payara Server Hazelcast Selection
  3. Check "Enabled" (and optionally "Dynamic" to apply the configuration without a restart) and save.

Enabling Hazelcast using Asadmin

The set-hazelcast-configuration asadmin command requires you to specify whether or not Hazelcast is enabled each time you run it. This command is also used to configure Hazelcast, which is covered in the configuration section. The command requires the Admin Server to be running, and will expect it to be listening on port 4848 unless specified differently with the asadmin utility --port option.

asadmin> set-hazelcast-configuration --enabled=true

If no target is specified, the command will enable Hazelcast on the domain configuration (server-config). To enable Hazelcast on another instance or cluster, use the --target option like so:

asadmin> set-hazelcast-configuration --enabled=true --target=${Target}

The dynamic option of the asadmin command defaults to true, so to enable Hazelcast and require a restart of the target instance/cluster, use --dynamic=false:

asadmin> set-hazelcast-configuration --enabled=true --dynamic=false
