IBM DevOps Code ClearCase vs. OpenText Media Management (OTMM)

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

It is expensive and needs dedicated support but it is a overall good product. I also really like the Dev team and support teams, they are really responsive and the community of users that support each other is great. You need an enterprise team to support this, it is not meant for a small team or shop.

• 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.

• Extremely buggy.

Over all it is fine, the system does have it quirks and challenges, I wish we could see the assets in bulk faster, it would be nice if there was more control around how things are downloaded. Overall the UI is clean and works well. the searching always works, and we have never had it not work when we need it to. the collections, sharing and links all work great.

OTTM team is great, the support and the user community they have built is amazing. I have check in with the product development team and they listen and are responsive. I can say enough about the user community, from the big big companies to the smaller ones, everyone is open and willing to help each other out.

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.

• Managed code versioning for many years.
• Only one person can edit code at a time - slows processing down.
• IBM is an expensive product to support.
