IBM DevOps Code ClearCase vs. OpenText Universal Discovery and Universal CMDB

IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control

Micro Focus Universal Discovery and Universal CMDB is well suited for medium to large IT operations after a careful review and strategy definition of all support tools that will be integrated. When it comes to deciding on a set of tools for IT operation management and its different processes like Incident, event, and change management; a good approach would be to create a roadmap with the integrated suite of tools to create a native ecosystem and reduce complexity on the integration and adoption.

• Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
• Rational ClearCase handles parallel development of many dependent applications really well.
• The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.

• Management and organization of Configuration Items
• Ensures a single and uniform source of database to avoid any ambiguity between departments.
• Proper delivery of services

• Extremely buggy.
• Sometimes the repository gets locked for no reason.
• Slow.

• When getting started the Cloud deployment may be not that easy.
• To manipulate the system deeply requires a professional operator.
• Working on large data project.

Old versions which do not support CMS have a luck of user experience and performance for reports and service modeling.

Some complex issues regarding performance and platform upgrades have been difficult to address and have short time solutions.

Upgrades from old versions were really hard to handle.

If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.

Quite competing products but short learning curve and fitment in our IT Landscape were main differentiators.
