Access Oracle Event Hub from external Tool or Command-Line Client

Oracle Event Hub provides a managed Kafka PaaS solution. To access it from an on-premises client you have to make sure to enable the ports to Event Hub Zookeeper and the Kafka broker.

First lets enable access to Kafka broker. To do so, check the OPC Event Hub service for the connect string.

Create Event Hub Broker Access Rule

Then create a new access rule. Warning: In general you should not allow public access to access your Event Hub service! This is just for demo purposes to make the tool work. In case of doubt create a rule with your own IP address and talk your friendly security officer first of all.

The creation of the rule might take a few seconds:

Create Zookeeper Access Rule

Once the rule for the Kafka broker is created, we need to create a rule for Zookeeper which is using port 2181:

Explore Kafka Tool (or other)

Now lets start our Kafka tool (for demonstration purpose) only, configure the connection details for the Zookeeper IP and port, and then try to connect to Oracle Event Hub Service:

Voila, it is working 🙂 You can explore your topics or even create new ones. Note that  Oracle Event Hub uses a special naming convention for topics.
