Difficult to use, not efficient, but stable
We are using IBM Rational ClearCase in Peru at two large banks for a code repository. However, it is not meant to be used as a repository I have found it very difficult to understand many functionalities in IBM Rational ClearCase. We have had many problems and it is not user-friendly.  I have…

Very flexible with Johnny-on-the-spot tech support
I would like to see them enable parallel development for online. It's available now for batch stuff on the mainframe. Jenkins, IBM, and Rocket all supposedly already have safe and workable version of Git for the mainframe. With that in mind, we need to know where our feature is. Unfortunately, as good as ChangeMan is, if we're listing downfalls, they should be talking to me about this. Not me having to go talk to them about it. Hopefully, they have this in the works and they are positioning their product for the future. That's just a straightforward comment. It really comes down to whether they are complacent or not. The other thing that should improve is cost. Git, even on the mainframe, a large part of the components "free". They're the way you set them up yourselves and they're self-sustaining and built into the infrastructure. You can't charge me for that. I gave ChangeMan an overall score of eight, but what could drive them to a nine is coming up with a way for all my code that belongs together to be tracked and moved together. Everything should move based upon the mainframe; it needs to be alerted and synchronized.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"What I like most is that it is very stable."
"IBM Rational ClearCase is a stable solution. I have not had any difficulty with reliability."
"I really appreciate the MultiSite feature; it is important to us due to the global nature of our company, as my team supports developers using ClearCase in at least ten locations worldwide."
"Therefore when we started using ClearCase, it was like a miracle."
"ClearCase integrates well with other engineering tools and frameworks such as the Eclipse environment."
"The features allowed us to meet requirements for SOX and set a centralized guideline for our development teams."
"The tool had features similar to Git for version control. It offered branching and merging capabilities, providing better control over code management. Integration was possible with other tools, including some change management tools. The overall process was normal."
"IBM Rational ClearCase is a stable solution, and I have not had any difficulty with reliability."
"Scalability is great. It has absolutely met every need for us so far. We do have some concurrent development paths and we're able to flexibly assign variables. At the same time, our skeletons assemble where we want them to, so the scalability is very good."
"Scalability is great; it has absolutely met every need for us so far, and we do have some concurrent development paths where we're able to flexibly assign variables while our skeletons assemble where we want them to, so the scalability is very good."
"What’s most valuable to me is the ability to compile the code and move it through the test and productions environments."
"Auditors really love ChangeMan for how easy it is to get through and how tight the security is on it."
"We audit once a year for our ChangeMan access, accurate financial programs, and all of that. Auditors really love ChangeMan for how easy it is to get through and how tight the security is on it. Our internal auditors, external auditors, and SOX editors love this solution. We're in the healthcare business, so HIPAA regulations and all such things are a big deal, and this makes all that really simple."
 

Cons

"I have found it very difficult to understand many functionalities in IBM Rational ClearCase. We have had many problems and it is not user-friendly."
"The solution's UI is slow compared to other tools. It is an old tool."
"I have found it very difficult to understand many functionalities in IBM Rational ClearCase. We have had many problems and it is not user-friendly."
"This is an expensive product and the price could be reduced."
"Customer service is mediocre. Technical support is mediocre."
"Look for a more modern product. Your suppliers and developers will be happier."
"IBM's support of ClearCase is slipping."
"The protection needs to be improved."
"I would like to see a better search tool."
"Their technical support is not so good. To be perfectly honest, that's one of the reasons we were looking at other solutions."
"I would like to see them enable parallel development for online. It's available now for batch stuff on the mainframe. Jenkins, IBM, and Rocket all supposedly already have safe and workable version of Git for the mainframe. With that in mind, we need to know where our feature is."
"I would like to see them enable parallel development for online. It's available now for batch stuff on the mainframe."
"As such, there's nothing wrong with the product. It is great, but there are small things that can be better to make it much more friendly. The way you navigate through fields can be improved. If I'm going to stage a component over something that exists and that I've created in another library, and I want to pull it in and write it over what I've got there in my package, I've got to type in that data set name every time. That can be aggravating. It is not a big deal. The way things are sorted can also be improved. If you're doing a delete of a bunch of components, you can't sort those out by type or anything. Some things are just standard, and you can't look at them in a way that would be helpful."
 

Pricing and Cost Advice

"This is a very expensive product."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
"It's on a yearly basis. I am not aware of any additional costs."
