1. Introduction

The Co:Z Co-Processing Toolkit for z/OS consists of the following components:

  • Co:Z SFTP: OpenSSH SFTP extended to support Datasets, SMF logging, FTP compatible user exits, and SAF/RACF Digital Certificate authentication. See the Co:Z SFTP User's Guide.

  • Co:Z Launcher and Dataset Pipes:

    • The Launcher is a batch utility which remotely launches a process on a distributed system, redirecting input and output from that process to traditional z/OS datasets or spool files. Remote processes are securely launched using proven SSH (Secure Shell) technology to the target platform, which may be Linux, Windows, or other Unix/POSIX environments.

    • Dataset Pipes are utilities that convert datasets to/from files. These commands may be used locally or over an ssh connection.

    See the Co:Z Launcher and Dataset Pipes User's Guide.

  • Co:Z COZBATCH: An improved replacement for BPXBATCH. This utility is often used in conjunction with Dataset Pipes or Co:Z SFTP. See the Co:Z COZBATCH User's Guide

1.1 Packaging

The Co:Z Toolkit consists of two packages:

Co:Z Toolkit for z/OS

  • Package contents:

    • Co:Z Launcher

    • Co:Z Dataset Pipes

    • Co:Z SFTP (client and server)

    • Co:Z Batch

    • Sample JCL

  • z/OS Host requirements:

    • V1R12 or later, with a minimum machine architecture of z9 and above

      [Note]Note
      Users running machine architectures lower than z9 or a z/OS release lower than V1R12 should use Co:Z release 2.4.5.

    • z/OS OpenSSH or IBM Ported Tools OpenSSH

      z/OS V2R2 includes OpenSSH. Earlier versions of z/OS require IBM Ported Tools OpenSSH v1.2 (or later) to be installed. See the version of our Quick Install Guides matching your z/OS OpenSSH version for additional information.

Co:Z Target System Toolkits

[Note]Note

Target system toolkits are only required by the Co:Z Launcher and / or remote Dataset Pipes components. All other toolkit components (e.g. Co:Z SFTP) run on z/OS and do not require target system toolkit installation.

The Co:Z Toolkit for Target Systems are supported on a wide variety of distributed platforms, including Linux, Windows, or other Unix/Posix platforms. The Co:Z Launcher is a particularly good fit for organizations that run both z/OS and Linux for System z connected via HiperSockets.

  • Package Contents:

    • Co:Z Launcher Agent

    • Co:Z Dataset Pipes client commands

  • Windows Target System Toolkit requirements:

    • Supports the following Windows environments: Windows 7, Windows 8.1, and Windows Server

    • Requires the Cygwin environment.

    • OpenSSH sshd (installed via Cygwin)

    • sshd_config AllowTcpForwarding=yes for target userid

  • Unix/Linux/Posix Target System Toolkit requirements:

    • OpenSSH sshd

    • sshd_config AllowTcpForwarding=yes for target userid

    • Pre-built binary packages are available for many Linux distributions.

    • Source code is also available for the traditional configure, make, make install process.
