Enable clustering in GlassFish

GlassFish is standard in “development mode” delivered.

When clustering is required, you can enable the “enterprise mode” in the admin console.
On the main page of the admin console is an option “add cluster support”. (see fig1)

Clustering Support

Before you start cluster support do not forget to make a copy of the domain.xml (default under glassfish/domains/domain1/config). So you can always easily return into “Development Mode”.

After you enabled the clustering support the GlassFish AS a restart is required. Clustering support is now available! (see fig2).
