  - Configuring z/OS® Extensions
    z/OS® Extensions include basic configuration tasks required to use the z/OS Extensions features and some optional configuration tasks. Some of these options need to be configured by an administrator and some need to be configured by individual users for their client environment.
  - Using the Remote Build feature
    The Remote Build feature submits build requests from DevOps Code ClearCase® client platforms running on Windows®, Linux®, and the UNIX® system to z/OS® (MVS™ and z/OS UNIX System Services). This feature consists of both server and client components.
  - Using the TSO Client feature
    Use the TSO Client feature to perform DevOps Code ClearCase® operations on the distributed system without leaving the mainframe system environment.
    - Quick reference for TSO Client
      This topic provides a synopsis of the functionality of TSO Client commands and panels.
    - Displaying TSO Client help
      This topic describes how to update your ISPF profile to display TSO Client helps. You need to do this task only if have used a previous version of z/OS® Extensions and your installation has upgraded to version 7.1.0.2.
    - Setting up your TSO Client environment
      Before you use TSO Client, customize your environment by performing these tasks.
    - Starting and stopping the server and client components of TSO Client
    - Working with views and streams
      Use the options on the View and Stream panel to select a view, create a stream, create a view, and synchronize a view with a stream.
    - Preparing to work with files
      After you set up your TSO Client environment and start the client component of TSO Client, you must complete these tasks before you can work with your files.
    - Working with files
      After you set up your environment, choose your view, and upload your files to the remote system, you can use the client component of TSO Client to perform basic file tasks with the files associated with your chosen view.
      - Locating files in a file list
      - Adding files to source control
      - Uploading files
      - Filtering file names
      - Filtering file states
      - Checking out files, checking in files, hijacking files, and merging changes
        This topic explains some of the things you need to consider when checking files in and out and provides links to instructions for checkout, checkin, hijack, merge, and undo checkout operations.
      - Copying a file
        z/OS® Extensions provides a copy operation that you can use to work on a file that is checked out by someone else.
      - Editing a file
        z/OS® Extensions provides an edit operation that you can use to edit files that are checked out, files that are not checked out, or view-private files. When used on a file that is under source control but is not checked out, this operation is similar to a hijack operation.
      - Working with previous file versions
        In addition to checking your files in and out, you can also use the client component of TSO Client to compare previous file versions and view the version history (version tree).
      - Deleting PDS members
        You can also use the client component of TSO Client to delete PDS members.

        Use the aat command to add attributes to a file under source control.
      - Enable REXX Trigger
        Enabling a REXX trigger for TSO Client commands.
    - Query files
      Once you set up your environment and choose your view, you can use the client component of TSO Client to perform query tasks by specifying certain criteria.
    - Building with TSO Client
      You can create either a local or a remote build by using the TSO Client feature.
    - Getting help with errors
      TSO Client displays short and long error messages to help you troubleshoot problems.
    - Opening the TSO Client log file
      TSO Client records messages in a log file to help you troubleshoot problems.
  - Managing builds with impact analysis
    z/OS® Extensions provides impact analysis tools that you can use to manage COBOL, PL/I, and High Level Assembler (HLASM) builds.
  - Using the TSO Client API
    The TSO Client API enables you to perform Remote Build functionality by using a TSO Client API application. Use the TSO Client API to create your own custom TSO Client calls to a distributed system running DevOps Code ClearCase®.
  - Using the ClearCase® Repository Access Manager
    ClearCase® Repository Access Manager (CCRAM) provides a seamless interface that enables those who use IBM® Rational® Developer for System z® to access assets stored in ClearCase.
  - Automating builds with parameterized build scripts
    Parameterized build is a script-based, sample-driven approach to automating Remote Build scripts. It provides you with sample scripts that you can use as a starting point for developing your own approach to automating Remote Build scripts. These sample scripts are provided as-is and require customization and alteration before they can be used in your z/OS® Extensions environment.

Compressing partitioned data sets

You can use the client component of TSO Client to compress partitioned data sets.

About this task

When a partitioned data set is full or there is not enough available space for it, uploading the PDS can fail. If you need more space for a PDS, you can compress the PDS and then try the upload action again.

Procedure

To compress a partitioned data set, do these steps:

On the option line of the TSO Client Main Menu, type 4.
On the left side of the Dataset Action panel under DSLIST, type z next to one or more data sets you want to compress and press Enter.
If the selected data set is not a PDS (such as a PDSE), TSO Client issues a message that the selected data set cannot be compressed.
