What do you like best?

IBM Rational ClearCase was one of the best version control tools when it came out. It ability to provide Dynamic and Snapshot views was cutting edge at the time. Branching and merging code was very simple using the built-in tools. It also provided the ability to geo-replicate the repository to different sites using an addon product called Multisite. Policy management is performed by using "triggers", which can be run using simple scripting languages to allow for extra policy checks. Latter versions also introduced UCM (Unified Change Management) which provided an out of box branching strategy to further simplify the development process Review collected by and hosted on G2.com.

What do you dislike?

At the time I would say nothing. However as time has progressed IBM Rational ClearCase is not longer a viable solution for a development team, especially as there is so many open source alternatives (Git, Subversion). It has now become quite a niche product with very few developers knowing how to use it. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Software Configuration Management is the main issue that Rational ClearCase resolves - however as stated above there are competitor products , most of which are open source that can surpass its abilities now. Review collected by and hosted on G2.com.

What do you like best?

Cleasecase is customizable according to the buniess area and easy to implement in a software integration environment. The GUI is quite user friendly and is easily understandable.

It could easily be implemented with the other IBM software tools for requirement handling, change management and defect tracking to make a unique tool chain. Review collected by and hosted on G2.com.

What do you dislike?

It is a bit expensive with the license and could have more features for the price charged Review collected by and hosted on G2.com.

Recommendations to others considering the product:

If you need a stable, reliable, user friendly and an easily understandable version management tool, then definitely Clearcase is one good option and if you have the IBM tool chain for all other stuffs like change management, defect management and so it adds to the value Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Clearcase solves many problems with the database maintenance of the software, easy to create a new build environment from scratch. I have realized that Clearcase has always been user friendly in terms of understanding the version trees, branching and so on.

It gives a good view of the files version controlled and their status of usage in a multi-user environment.

Clearcase is a quite stable tool to rely on for future build implementation. Review collected by and hosted on G2.com.

What do you like best?

One big benefit is that intellectual property is always in the corporate Network. So it is more secured. another is the instant access of source files without downloading Dynamic Views. Must admire a fully functional translucent file system.

One big benefit is that the Intellectual Property is always in the corporate network. A laptop can be lost/stolen and no source code in jeopardy.

Another is the instant access to source code and changed files, no time is ever spent downloading anything.

It serves well for the purpose it has. Review collected by and hosted on G2.com.

What do you dislike?

The support is terrible. We've had tickets open for years. Our eclipse guru actually fixed a bug in their eclipse plugin locally in about 30 minutes by disassembling the java file. But the ticket still hasn't got past level one support. Review collected by and hosted on G2.com.

Process, process, process: every step of the development phase is perfectly described and easy to check. The UI is also, although a bit too old fashioned, quite clean and simple. Review collected by and hosted on G2.com.

What do you dislike?

Excessive amount of data makes this software definitely not user friendly. It's also prone to slow down or just getting stuck for minutes. Review collected by and hosted on G2.com.

What do you like best?

I used CC for version control of codes in my company. I found it very useful because many a times a project would be divided into multiple sub projects and would be given to us for implementation. We can load the latest version and make our changes and merge to the mother branch once done. This gives good visibility and tracking of each individual's work. I also liked the functions like we could compare two version side by side. This was useful in reviews. Review collected by and hosted on G2.com.

What do you dislike?

I sometimes feel it s a bit slow. Also the GUI is a little harder than other competitors. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

It is very powerful and can mange huge repositories. It is suitable for big enterprises and multinationals where development happens across countries. Review collected by and hosted on G2.com.

We mainly used CC for version control and to manage document repositories. Also CC facilitated to provide a particular employee access to only document he needed. Review collected by and hosted on G2.com.

What do you like best?

Every code file, document, check-in documents etc. that made the CRM application of my project, was stored and managed through Clear Case (CC). Every time we changed any component in the application, we had to check-in this new component in CC. It kept a proper hierarchical track of the different versions of files checked in. It makes it very simple to keep a track different versions of the files. Also, we could access any file version to view what changes were made in it.

The best features it offers is that, before we check in anything we can compare the old file and the new one we are adding. It shows us the old and new version side by side so that we can compare the changes we made. Also, once checked in, it allows us to undo the check-in. Review collected by and hosted on G2.com.

What do you dislike?

If a particular folder has a lot of components in it, it takes a very long time to load everything. Until everything is loaded, you cannot do any task on the components.

A lot of steps are to be followed for checking in a document, making it very time consuming. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Good application for version control system, but too many steps are to be followed systematically in-order to check-in a new file or to undo a previous check-in. A better application with a better ease of use i will be preferred. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

We basically use this for maintaining the versions of various documents. Also used to track old changes and various project documents. Review collected by and hosted on G2.com.

What do you like best?

Our team uses ClearTeam Explorer for source control. I like the way we can compare different versions of a code file side by side within this application. But otherwise, I feel this is outdated and there are many other better version control systems out there like GIT SourceTree which is more user-friendly Review collected by and hosted on G2.com.

What do you dislike?

Clumsy UI

Very slow. Especially if used intermittently with some idle time in between, it takes a lot of time to respond.

Needs the user to check out the file before editing it, rather than automatically detecting the modified files. If a user modifies a file without checking it out, the file gets hijacked.

A lot of time is wasted to wait for the connection, check out the files and check-in them again. I like the way how it works in SourceTree. Users change the code, SourceTree would detect all the modified files and then commit the changes.

Poor documentation.

The application keeps throwing errors without much information about what is causing the error.

View management is not very straightforward Review collected by and hosted on G2.com.

What do you like best?

you can automate a lot with this tool and you have to think to use it in right way. Support most popular platforms, great customization features, can be used for high availability model. No limits for version data storage. This is old product and most errors already fixed. New bugs are rarely observed, because there are not too much new development efforts provided for ClearCase. Review collected by and hosted on G2.com.

What do you dislike?

developers have no time to learn it and use by themselves - they need administrator who will help them. GUI looks rather old style and obsolete, IBM don't drive ClearCase development now and it looks like we have very small new features in future releases (in case we will see new releases). There are no real support for different development models - it's hard to use CC for traditional (waterflow) teams together with SCRUM or Kanban teams. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Very powerful tool required a lot of administering and maintenance, so it's good to use for big projects with many developers and big code base, but not useful for small short projects when you will not support and develop code for several years. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

All problems with version control, configuration and release management. For business - you can control your development with many branches for different releases, versions, fixes etc. This is especially important for big enterprise projects, because there we have core mainline development with many additional branches we should manage in parallel.

What do you like best?

A nice Document control system, which ties into our internal Work Request and Change Request processes (via Clear Quest). A somewhat easy search feature for finding older documents, we have been using this in my current department for our Build documents which contain our specifications of our steps when building out a server. It has other uses, beyond the few that my immediate department uses, such as allowing a tracking all changes made to a script or document and tracking the changes from cradle to grave. Review collected by and hosted on G2.com.

What do you dislike?

There are a few improvements needed, such as an easier way to upload documents than the way we have it configured, by linking it to a Work Request. We also have it configured to store individual “views” locally on workstations, instead of a central repository, which is bad when a workstation’s hard drive “dies”.

Always do plenty of research before locking yourself (or your company) into a specific product. Review collected by and hosted on G2.com.

We are able to keep track of our changes to our documentation and search for previously made changes very, very easily. Our internal turnaround has been reduced to under a week, and allows us to easily find any abnormalities that have been made to a similar built system by checking the documentation changes.

My team uses Clearcase primarily as a document repository. Clearcase provides version control and enables users to quickly switch between views though a GUI interface. Access to views can be tightly controlled so that users only have access to objects required for their work and documents can be organized into directories which can also be put under version control. Review collected by and hosted on G2.com.

What do you dislike?

Installation of the Clearcase client is a complex process requiring several reboots. As a result, deployment of this tool was diffcult to automate using SCCM. Infrequent users of this tool frequently struggle with the processes that must be followed to add new documents and/or make changes to existing documents. Review collected by and hosted on G2.com.

Rational ClearCase has provided us a powerful configuration management tool. It provides a thorough change history if used correctly. Build triggers and Linux environment support provide a great build environment. ClearCase allows for easy version comparisons which facilitate peer reviews. Review collected by and hosted on G2.com.

What do you dislike?

Because of the size of the software it can be difficult to migrate when changing environments. ClearCase's integration with source code on user machines is lacking and frustrates some developers. It can be very tricky because some triggers can seem hacked together. Review collected by and hosted on G2.com.
