Here’s one for subversionadapt it to your Clearcase process. And I pick and choose for each program which library functions are used.
Getting started with UCM
So that’s something one should know about ClearCase – most developers are really happy to work with something simple as subversion or git yes, even git is easier to graspAnd even after I knew how to complete the simplest tasks in ClearCase, I had the constant feeling ClearCase works against me, not with me.
Once you understand how that’s done and Clearcase does it very well, to the point where we do even small changes as a branch and re-merge, not something I would have ever done with RCS or CVSyou’ll find your life is made a lot easier.
Don’t move files around to different directories. Slow, buggy, and expensive. Views Read Edit View history. Retrieved from ” https: Unless you have one, people are going to run into problems and soon enough there will be talk about the “ClearCase” problem.
Rational ClearCase is a family of computer software tools that supports software configuration management SCM of source code and other software development assets. So, that’s a moderate summary of why I like to embed the version information in the source files.
It only affects a singe file, or a single directory without its tutorixl ct findmerge is recursive.
UCM Administrator Tasks
I think what you’re missing is a CC administrator that knows what they’re doing. CC is not a bad product, It’s just sometimes poorly understood. Almost every other modern tool is “repository centric”, with uucm atomic commit transaction, but first-generation systems like RCS, SCCS, CVS, and most other older systems do not have that feature. The dependency information is stored in a configuration record that can be shown for each derived object.
The configuration record can also be used to apply a label to the files and versions that were read during the build.
The “thread” concept corresponds to the dynamic view. How to use git on top of ClearCase! Based on the tools today, not so much. I was told it should have sophisticated features, but as a svn and git user I cannot possibly think of something I miss in git or subversion.

I can half see why; I’m not sure I like giving up that trackability, tutoriao. When you check out you lock the file until you check-in it in.
Why I still think metadata in the file is good I like to have the metadata in the source code because my source code as opposed to my employer’s source code is distributed outside the aegis of the source code control system. Embedded Version Numbers – Good or Evil? Commercially, my employer used SCCS up to mid, clewrcase they started to switchover to Atria ClearCase from earlytackling separate uvm sets one at a time.
Consequently, even if someone takes a chunk of my source code and modifies it, there are usually labels enough in it to identify where it came from, rather than leaving me to speculate about which version it is based on.
ID keywords take two formats, one for files being edited and one for files that are not being edited: The only gripe I have about UCM is that history cannot span components. Directories can be branched – cautiously – and certainly are version controlled. I am talking about clearttol. Use a common config spec and don’t change it very often.
When starting a new code-base, make sure you get the streams and projects layout right from the start by planning ahead. Although by default checkouts are reserved lockedyou can always unreserve the checkout later, or create the checkout unreserved. It supports branching, labeling, and versioning of directories.

Create a process that describes how you will use the version control system. Fine tune the privileges of users and set up triggers for common events to prevent common mistakes or enforce policies. Version trees are essential to understanding what has been happening to a file.
When project managers announce that a new recommended baseline is available, you synchronize or rebase your work area with the activities in the new baseline. There is a very handy command cleardescribe that is useful many times.
My views verge on the archaic, but have a rationale behind them, and I’m going to take the time to write them down messed up by life – it may take several edits to complete this. I’ve not used a better mergetool, but that may not be saying much since I’ve not used any other graphical mergetool. At any time, a view-private object can be added to source control and become a versioned object, rendering it visible to other users.
That is, it is mostly open source – I make it available to all and sundry. A major innovation was the use of build signatures and software release signatures in the thread. However, once generated, it enabled DSEE to calculate the optimum way to perform a build, re-using all modules that had previously been processed and whose version specifications matched the specifications for the build.
ClearCase includes revision control and forms the basis for configuration management at large and medium-sized businesses, accommodating projects with hundreds or thousands of developers. Finding the correct version, though, seems key to doing that, and if there are fingerprints in the code, then it can be easier.
Learning objectives After completing the lessons in this module you will know understand the concepts and know how to do the following: When a developer leaves the project have someone to remove all the views he had on his machine and delete all his private streams.
Always put good comments when you check in. CC does need good administrators – we have them and are fortunate in doing so.
