    - Working with the Role-based Resource Manager
      The Role-based Resource Manager adds a layer of security for accessing system resources.
  - 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.
  - 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.

Authentication modes for Remote Build

You can configure options for authenticating users to the Remote Build server.

The Remote Build server interfaces with IBM® RACF® or other compatible security products to perform the following tests:

Validate TSO user IDs and passwords that are passed by the client command.
Verify user authorization for z/OS® MVS™ libraries and z/OS® UNIX® System Services directories accessed during a build request.

A user ID that passes these tests receives access to the Remote Build process.

The following table describes four server authentication modes. You choose an authentication mode by setting the -a runtime server option in the RCCRUNM (for z/OS® MVS™) or RCCRUNU (for z/OS® UNIX® System Services) JCL member.

Table 1. Server authentication modes
Mode	Description
0	No user authentication. The user ID that starts the Remote Build server is used for build processes requested by all users.
1	The user ID and password, passed by the client, are optional. If supplied, they are verified with the security product (such as RACF®).
2	The user ID and password, passed by the client, are required. The security product (such as RACF®) verifies them.
S	The user ID and password, passed by the client, are required. The security product (such as RACF®) verifies them, and an optional role can be supplied on the build request. This option is supported on z/OS® MVS™ only.
