Introduction

IBM continues to deliver value to customers not only through major releases of IBM DevOps Code ClearCase but also via regular fix packs. The latest set of updates—ClearCase 11.0.0.04, 10.0.1.04, and 9.1.0.09—became available on 31 August 2025.

Each release provides important PSIRT (security) and APAR (defect) fixes. Beyond that, ClearCase 11.0.0.04 and 10.0.1.04 introduce significant new capabilities designed to improve developer productivity, integration flexibility, and system performance.

What’s New in 2025B

1. Type Manager Enhancement: Container Management on the VOB Server (only in 11.0.0.04)

ClearCase’s type manager provides flexible, extensible file management with efficient version storage in VOB containers.
Traditionally, container management operations ran on the client machine, which could introduce performance bottlenecks and network file system overhead.

With this enhancement, administrators can configure container management to execute directly on the VOB server:

• Reduces client-side processing load.
• Improves performance by eliminating network file system writes.
• Enhances security by keeping container modifications local to the VOB server.

The type manager server can be enabled (by the administrator) on a VOB-by-VOB basis. 

Also, in a cross-rev scenario (e.g. both ClearCase 11.x and ClearCase 10.x systems), the container management will continue to execute on the client to maintain compatibility.

Note: Windows VOB servers hosting many VOBs may see limited benefit initially, but further optimizations are planned.

2. New IDE Integration API (DevInt API via REST STOP)

Developers often use ClearCase alongside IDEs such as Eclipse or Visual Studio Code. To expand and simplify integrations, IBM is introducing the DevInt API, built on the new REST STOP (REST Server Through Operational Proxy) architecture.

The DevInt API and CLI are being published to support customers who want to implement their own integrations with ClearCase, in addition to the standard integrations already available.

Key highlights:

• Runs a proxy process on the client to manage ClearCase client state.
• Communicates with ClearCase servers while coordinating view and VOB operations.
• Supports all four view types: dynamic, snapshot, automatic, and web.
• Initially available in silent mode (all arguments provided by caller).
• Roadmap includes interactive mode (dialog prompts for missing arguments).

DevInt CLI for Developer Tooling

Alongside the API, a new DevInt CLI (Command Line Interface) standardizes ClearCase operations across all view types.

• Ensures consistency and simplifies automation.
• Provides results in JSON format for easy parsing and integration.
• Streamlines developer workflows with fewer manual steps.

3. Extended JSON Output Support (only in 11.0.0.04)

Automation often requires reliable, machine-readable output. While earlier releases added JSON support for cleartool catcr and cleartool getcache, ClearCase 11.0.0.04 extends this feature to two of the most frequently used query commands:

• cleartool describe
• cleartool lshistory

Benefits:

• Simplifies scripting in languages like Python, Perl, Java, and C++.
• Eliminates the need to parse human-readable text output.
• Provides both standard JSON and compact JSON (jsonc) formats.

Example options:

–sfmt [json | jsonc] [–ofile filename]

-sfmt json

Summary

The 2025B fix packs (9.1.0.9, 10.0.1.4, 11.0.0.4) demonstrate IBM’s commitment to ongoing ClearCase innovation. With security fixes, extended automation support, and major developer-focused enhancements, these updates strengthen ClearCase’s role in modern DevOps toolchains.

• Type Manager now executes container management directly on VOB servers.
• DevInt API & CLI open the door to streamlined IDE and tool integrations.
• JSON output is expanded to key commands for easier automation.

ClearCase continues to evolve with both enterprise stability and developer agility in mind.
