IBM DevOps Code ClearCase vs. LinearB vs. Perforce P4

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 gives you an amazing dashboard with graphs and data that helps in analyzing our work. Through cycle metric tracking, the throughput of your teams is great as compared to agile metrics such as Scrum Velocity.

While Perforce Helix is the best version control software out there, it can also be used to track your documentation, training videos and materials, and requirements. If you have strict compliance requirements, it can be used to ensure that those requirements are satisfied. Perforce Helix is incredibly flexible and can meet the needs of individual users as well as companies with thousands of users.

• 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.

• The branching mechanisms in Perforce allow for an enormous codebase to be duplicated into release versions weekly with little impact upon things such as the speed of queries against the version control.
• Action triggers permit such things as automated builds of software versions, dynamic messaging when issues are identified either within or prior to a build process, and much more.
• Locking provides the ability to prevent modifications of stable, tested versions in order to ensure validity when they are released.

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

• Tracking work based on Kanban methodology has some glitches and is not fully supported in linear.

Incentivized

• Perforce tends to feel backwards in how it approaches certain tasks, like branching and integrating - even once you figure out how it wants you to perform these tasks, you will likely forget when it comes around to the next time you need to do them again.
• Perforce has a higher price tag, comparatively.
• Perforce make some tasks very easy, and yet other tasks very difficult - it doesn't always seem to have found its target user's proficiency.

We are fully committed to our use of Perforce. It works well within our organization and our desire to share our code base with our customers. Their support staff are responsive, inquisitive, and eager to improve their software. I feel like we have a direct line to their design/feature team as they often solicit our feedback.

With Perforce Helix, you can use it via the command line, via P4V, or any of the other APIs included with the product. It is extremely easy for new users to get up and running. Users of Perforce Helix only have to pull in the files of interest to them. Also, Perforce is very easy to script and integrate into your CI/CD pipeline. Streams allows you to have pinpoint control of your workflow, and P4Search is the absolute best--I wish Perforce (the company) would talk more about this. It is absolutely fabulous!

In our large environment, Perforce is rarely "down". We have regular maintenance windows and from time to time Perforce can feel a little slow, but its always available. Tech support has always worked with our engineers and IT department to make sure that any real performance or stability issues are addressed quickly.

I had two representatives from Perforce contact me after downloading it but never responded when I had questions. I also had a difficult time finding good training material for getting started. There is a lot of available support material when running into issues, though, because of how many large companies use it.

This rating is related to setting up an environment from an existing Perforce repository. Initial setup of Perforce as the repository for the company was done by a separate team long prior to my inception.

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.

Git is great, I love Git. But it's not great for dealing with binary assets, even when using Git LFS. Locking is not as simple as on perforce. Git presents some problems on using for non-tech people it can get overwhelming and tech people have to come by and help.

• 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

• Decreased our implementation costs by allowing versioning and back out of customizations made in the field.
• saves developers time through automation of changes between branches - they think less of the plumbing and have more time to write code.
• Downside is training/managing expectations of new developers who come in assuming they will use Git.
