        Use the -V option to set message verbosity.
        Setting the condition for valid return codes
        Use the following options and arguments to set the condition for valid return codes. After each job step is executed, the system performs the condition test against the return codes from completed job steps. If a job step fails the condition test, the job will be terminated.
        Specifying a timeout factor
        Use the -T option to specify a timeout factor.
        Setting environment variables

    - Working with build scripts
      The build script for the Remote Build feature of z/OS® Extensions is called BCL (Build Control Language). It is similar to z/OS MVS™ JCL in appearance and, for many basic parameters and options, it is identical to MVS JCL.
    - Using Remote Build with the clearmake command
      The clearmake command is the DevOps Code ClearCase® variant of the Linux® and the UNIX® system make command. Using clearmake, you can audit remote builds and trigger future build events.
    - Sample build requests
      The topics in this section illustrate how to submit two different Remote Build requests using the client command rccbuild.
  - 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.
  - 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.

Glossary

Setting environment variables

Use the -v option to set environment variables.

Syntax

–v variable-name=value…

variable-name=value…: Specifies the list of variables and their values that are used to modify the build environment. Variable names are limited to 30 characters.

Platforms

z/OS® MVS™, z/OS® UNIX® System Services

Build environment variables are used differently in z/OS® MVS™ and z/OS® UNIX® System Services:

In z/OS® MVS™, the –v option works in conjunction with user-defined variables on a DD statement.
In z/OS® UNIX® System Services, the –v option changes or sets an environment variable. It is the equivalent of using the C language command putenv().
