Changing the Event Data Store TCP Port
Besides the HTTP port, clients can use the TCP port to make calls to Event Data Store. In addition, the nodes in an Event Store cluster use the TCP port to communicate with one another. The default TCP port is 9340.
To change the Event Data Store TCP port
1. In Command Central, navigate to Environments > Instances > All > instance_name > Configuration.
2. Select Ports from the drop-down menu.
3. Click tcp port and specify values for the following fields:
Field | Description |
Port Number | Required. The TCP port number. The default value is 9340. |
Use SSL | Optional. Enable Secure Sockets Layer (SSL) for the TCP port. Note: |  When you enable SSL for the TCP port, you automatically enable SSL for the HTTP port as well. The Event Data Store uses the Search Guard SSL plugin for Elasticsearch. For more information about the Search Guard plugin, see the Search Guard documentation. |

4. Optionally, click Test to verify your configuration.
5. Save your changes.
6. Restart the Event Data Store instance.
Important: | If you change the default TCP port, you must change the respective value in the Clustering configuration. |
