IBM DevOps Code ClearCase vs. National Instruments SystemLink

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

There are definitely scenarios where NI SystemLink will be useful but just didn't work out well for us. I needed to be able to replace an EXE file on a computer with a new EXE to do the upgrades but I was not able to do that through SystemLink. You had to work with packages in order to perform this and I didn't want to revamp my distribution plan. We also didn't need to do any asset management or calibration documentation through SystemLink. I was excited about being able to view data from the test stations through a browser but our engineers need historical data available and everything resets to a live view when you click back to the UI.

• 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.

• Setup
• User Interface

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

• Licensing
• Not able to see data from all test stations on one UI
• Lack of data history

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.

Incentivized

• Availability to monitor multiple test stations remotely
• Was quick to integrate into existing LabVIEW codebase
• Ultimately did not justify the licensing cost for the benefit
