Certified z/OS Version¶
Connect on z/OS is certified with z/OS version 2, release 4. For more details, see IBM z/OS Version 2 Release 4
Get Started With Connect on z/OS¶
This section helps you get started with Connect on z/OS. Before you begin, ensure you meet all the following requirements.
- Download the IBM MQ Source and Sink connectors for z/OS from Confluent Hub.
- Download the Connect on z/OS tar file.
- Access to z Systems Integrated Information Processor (zIIP). Ensure you have SSH and SFTP access enabled on the z/OS environment. You will need this to upload the Connect TAR file for z/OS.
- Java compatibility with z/OS. For more details, see the IBM Support documentation.
- z/OS UNIX (USS).
- Install Bash. The user performing the following steps must have access to the Bash command with privileges to run scripts. You can install Bash from Rocket Software or Anaconda.
- Ensure a dedicated user in USS has a bash shell and permissions to read, write, and execute the untarred connectors downloaded from Confluent Hub.
- Confluent’s IBM MQ Source and Sink connectors will access IBM MQ in bindings mode by default. Bindings mode is more secure than client mode.
- The default port for Kafka Connect in distributed mode is 8082. You must
ensure this is open so the connector can communicate. To specify a
different port, set the
rest.portconfiguration property in the connector’s configuration properties file.
- The default port for Kafka Connect in standalone mode is 8083.
This quick start shows you how to integrate mainframe data with Kafka. Use the following steps to set up Confluent’s IBM MQ connectors on Confluent’s Kafka Connect certified for z/OS.
Step 1: Download and extract the TAR file¶
Download and extract the TAR file containing Confluent’s Kafka Connect worker node for z/OS from https://packages.confluent.io/archive/7.5/confluent-connect-7.5.0-zOS.tar.gz.

This will result in a
Upload the TAR file to the z/OS machine.
Untar the TAR file by running the following command:
tar -xvf confluent-connect-7.5.0-0-zOS.tar
Step 2: Convert files to EBCDIC encoding¶
Log into the z/OS machine with a SSH terminal:
ssh -p <port> username@<ipaddress>
Navigate to the z/OS folder:
iconv -f ISO8859-1 -t IBM-1047 ./connect-standalone.properties > connect-standalone2.properties
Step 3: Set path to dependent libraries¶
Export the following environmental variable:
This is a path to the bindings shared object–it is important to run the connector in bindings mode so the connector can find all the native libraries.
If you are setting up the IBM MQ Source and IBM MQ Sink connectors, ensure you follow the steps listed in the Client Libraries section.
Step 4: Download the IBM MQ Connectors¶
Download the IBM MQ Source and Sink connectors for z/OS from Confluent Hub.
Step 5: Run the connector worker node¶
Run the Connect standalone worker node by running the following command:
./bin/connect-standalone.sh ./config/connect-standalone.properties ./ibmmqconnector.properties
