Connect to a remote GR from the IDE

As of System Platform 2017, communication from a GR with a local IDE (single node with both IDE and GR) is blocked by default to a remote GR. This applies to using the IDE to configure a Galaxy on a remote GR, as well as runtime.

If the IDE you are running has a GR on the same node and you try to pair with a Galaxy on a remote GR, you will get an error message that communication with the GR node cannot be established.

Scenario 1

The nodes have the following configuration:

• Node 1: IDE + GR (Galaxy 1)

• Node 2: GR only (Galaxy 2)

• Node 3: IDE only

To establish communication with the blocked GR in Scenario 1

1. Open the IDE on Node 1 and connect to Galaxy 1.

2. Configure Service Discovery for Node 1, and set Node 1 as the Local Galaxy Server and Cross Galaxy Server (Galaxy > Configure > Communication > Cross-galaxy server).

3. Open the IDE on Node 3 and connect to Galaxy 2.

4. Configure Service Discovery for Node 2, and set Node 2 as the Local Galaxy Server. Set Node 1 as the Cross Galaxy Server (Galaxy > Configure > Communication > Cross-galaxy server).

5. Configure Multi-Galaxy for each Galaxy. Use the Node 1 IDE to configure Multi-Galaxy for Node 1, and the Node 3 IDE to configure Multi-Galaxy for Node 3.

   Make sure that you use the same Passphrase for both nodes.

Scenario 2

The nodes have the following configuration:

• Node 1: IDE + GR (Galaxy 1)

• Node 2: IDE + GR (Galaxy 2)

To establish communication with the blocked GR in Scenario 2

6. Open the IDE on Node 1 and connect to Galaxy 1.

7. Configure Service Discovery for Node 1, and set Node 1 as the Local Galaxy Server and Cross Galaxy Server (Galaxy > Configure > Communication > Cross-galaxy server).

8. Open the IDE on Node 2 and connect to Galaxy 2.

9. Configure Service Discovery for Node 2, and set Node 2 as the Local Galaxy Server. Set Node 1 as the Cross Galaxy Server (Galaxy > Configure > Communication > Cross-galaxy server).

10. Configure Multi-Galaxy for each Galaxy. Use the Node 1 IDE to configure Multi-Galaxy for Node 1, and the Node 2 IDE to configure Multi-Galaxy for Node 2.

    Make sure that you use the same Passphrase for both nodes.
