2. Co:Z Launcher Installation

In order to use the Co:Z Launcher to enable z/OS batch jobs to remotely launch a process on a distributed system, installation is required for the Co:Z Toolkit for z/OS. Additionally, the Co:Z Target System Toolkit must be installed on the remote systems that you have identified.

2.1 Co:Z Launcher environment requirements

  • z/OS requirements

    • Co:Z Toolkit for z/OS

    • Batch job userid allowed to listen on local port; OMVS segment required

  • Target System requirements:

    • Co:Z Target System Toolkit

    • OpenSSH sshd

    • sshd_config AllowTcpForwarding=yes for target userid

2.2 Co:Z Launcher Quick Start

After completing the installation of the Co:Z Toolkit for z/OS and the Co:Z Target System Toolkit on the remote system, the following are the minimum steps to get started using Co:Z Launcher. For more detailed information, see the remaining chapters in this guide.

On z/OS:

  1. Edit //COZUSER.COZ.SAMPJCL(COZCFGD), updating the server-path variable with your installation directory.

  2. Edit //COZUSER.COZ.SAMPJCL(COZPROC), updating the LIBRARY and COZCFGD arguments with your installation datasets.

  3. Verify that /etc/ssh/sshd_config has AllowTcpForwarding=yes. If not set, update the sshd configuration. Restart SSHD with the following:

    kill -HUP $(cat /var/run/sshd.pid)

  4. Test that the z/OS user running Co:Z Launcher jobs can SSH to the target system without an interactive password.

    ssh user@linux1.myco.com

    See OpenSSH keypair authentication for additional information, if needed.

  5. Create and test JCL similar to the example provided here: Running with an OpenSSH keypair. This JCL is also included in //COZUSER.COZ.SAMPJCL(RUNLNCH).

  6. Once this test job runs successfully, experiment by trying Co:Z Launcher Examples. See General Dataset Pipes Examples for some Dataset Pipes commands to add to your JCL.
