"Outdated source control software"

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 But otherwise, I feel this is outdated and there are many other better version control systems out there like GIT SourceTree which is more user-friendly

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

Recommendations to others considering the product

There are many other better version control systems like GIT SourceTree.

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

Source control for .NET application development.

"Real enterprise CM tool"

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.

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.

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.

What business 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.

"ClearCase use on a day to day basis"

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.

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”.

Recommendations to others considering the product

Always do plenty of research before locking yourself (or your company) into a specific product.

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

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.

"Development Artifact Repository"

What do you like best?

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.

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.

Recommendations to others considering the product

It might be helpful to create a short document that describes how to perform the most common ClearCase operations to assist infrequent users with the operations they are most likely to perform.

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

This tool is used to handle version control of code and the accompanying artifacts. Use of this tool allows numerous employees to work on a single document or piece of code without loss of changes.

"Robust But Can Be Slow"

What do you like best?

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.

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.

Recommendations to others considering the product

Very powerful but can be difficult to use and setup.

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

We use Rational ClearCase as a configuration management and version control tool for both software source code and documents. We have increased the clarity of our version control trees which has decreased our merge times.

"Powerful Solution of Software Configuration Management"

What do you like best?

ClearCase help all scale development organizations to develop more effective and maintain and strengthen competitiveness, increase revenue and reduce cost.It can enable the development team to accelerate the development process, and to ensure that the correct Release and reliable build version, and to establish an effective development process, not to change the original development environment and work mode.

What do you dislike?

Clearcase supports most of the existing operating system, but its installation, configuration and use are relatively complex.Company need spending some time training the whole team.What's more,it's very difficult to install and is pretty heavy for me.

Recommendations to others considering the product

Software development is not an easy thing, the first is facing the management of a variety of products, version and other issues, the more complex is composed of two or more groups of people to jointly develop the same program, coupled with the diverse development process, making the entire development process is very difficult to carry out effective management.Rational ClearCase is a software development tool to solve previously unable to track the entire development process problems

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

I use it to track changes of each file and directory.In the software development environment, ClearCase can be implemented for each object type (including source code, binary files, directory content, executable files, documents, test kits, compiler, library files, etc.) to achieve the version control. As a result, ClearCase provides the ability to build a secure and reliable version history for each type of information that they deal with, as well as the ability to help the team in developing the software.
