Follow the GridGain 9 documentation to start the cluster.

-
Click the + icon on the Control Center toolbar.

In he Attach cluster dialog that opens, select the GridGain 9 tab.
-
In the URL of the GridGain REST API field, enter the cluster URL.
-
If you are attaching a secure cluster, enter Username and Password that correspond to the credentials of one of the users included in the cluster configuration.
