将 IBM iSeries 连接到 Kafka

Question

We are trying to connect a process within our AS400 to deliver information to a database that is in SQL Server 2016. We have an Apache Kafka server running and ready. What is the best way to connect the i Series to SQL Server using Apache Kafka? in such a way that an RPGLE program can deliver a message subscribed to a specific topic in Kafka.

Should we install something additional? are there open source options?

What should we configure?

Answer 1

I suspect this should probably be closed...

But, I'll throw the following out here....

There's various ways for RPG to interact with REST services

• open source HTTP API
• IBM's own Integrated Web Services (IWS) client
• Db2 built in functionality
• various commercial libraries ( GETURI for example)

Rather than interact directly from the producing RPGLE program, it's likely a better idea to have the RPG drop a message on a queue and have some background process send it out.

That background process could be all RPG, all Java, or RPG using Java classes.

JTOpen, aka JT400, is the opensource version of the IBM i Toolbox for Java.

If for instance you wanted an all Java process to read from the queue and send a message.

You can even throw Apache Camel into the mix since it supports both a JT400 and Kalfka connector. Here's an example repo of showing Camel running on the IBM i reading from a data queue and sending to Kalfka.
