Product Overview

SCLM's architecture is centered around ISPF and z/OS datasets. The main components include: * **ISPF Panels:** These provide the user interface for interacting with SCLM. Developers use ISPF panels to check out code, make changes, and check code back in.

* **Project Definition:** This defines the structure of the project, including libraries, languages, and build procedures. The project definition is stored in a z/OS dataset. * **Controlled Libraries:** These are z/OS datasets that store the source code and other artifacts under SCLM control.

SCLM manages versions of the code in these libraries. * **Build Procedures:** These are sets of JCL (Job Control Language) statements that define how to compile and link the code. The BUILD command executes these procedures.

SCLM integrates with z/OS security systems such as RACF, ACF2, and Top Secret for authentication. It uses Access Control Lists (ACLs) to manage access to resources. Communication between components is primarily through ISPF and z/OS system calls.

SCLM relies on z/OS datasets for storage. SCLM's architecture provides a structured environment for managing source code on z/OS.

Frequently Asked Questions

What is SCLM and what does it do?

SCLM is a feature of ISPF on z/OS that manages source code, tracks changes, and controls software releases. It provides a structured environment for developers to manage code modifications and maintain version control.

How does SCLM manage source code?

SCLM uses project definitions and controlled libraries to manage source code. Developers check out code, make changes, and then check the code back in. SCLM tracks these changes and manages versions.

Is there a cost to use SCLM?

SCLM is included as part of the base z/OS ISPF product, so there is no separate charge for using SCLM. It is available to all z/OS customers who have ISPF installed.
