I’ve been struggling to install the beast that is Clearcase 7.1.1 on a proof of concept server.
In this case the server is a Solaris 10 64bit install running on VMware Fusion 3.
One of the initial mistakes I made was to try and run the installation from a network mount. DON’T. Solaris must block the execution of code on some types of removable drives, which in this case was a VMWare Fusion shared folder.

I previously showed you how to use a shell script with Rational Clearcase, to alert you when a new branch type was created.
In this post, I will show you how to use a Perl script to enforce Clearcase labeling conventions. This example is directed toward Clearcase on UNIX (i.e. Solaris or similar) and assumes you have Perl installed, working and have a basic knowledge of how to program in Perl. It is a reworked version of the windows script supplied by IBM on Developerworks.
This is a long post, but a good one if you are a new clearcase admin who needs to enforce label names.
I was looking for a simple way to have someone emailed when an event occurred in Rational Clearcase, like a new branch type being created. If you run Clearcase on UNIX (i.e. Solaris or similar) you can whip up a simple shell script and create your trigger. I will assume you have sendmail or similar already configured on your host so that mail utilities can send smtp mail
Lets have a go at it.
I’m coming to appreciate IBM’s Rational Clearcase, aside from the price point of course. But work have a license for it, and I have to use it. Don’t get me wrong, CVS is fantastic for tracking your small projects or larger ones with average complexity. I still use CVS for my own code, BUT clearcase has these features built in that you just start to take for granted. Here is a list of the ones I think make it a cut above CVS on a time intensive and complex project:
I found myself writing down example commands in clearcase (V6), so I thought I would share them. If you have ever needed to find files like you do in UNIX, but want to be clearcase specific, then these commands will give you a quick headstart on using the cleartool find command:
How do I list all files and file versions going into a specific build that is labelled?
Assume your label is TR1_PRE_RELEASE
I was wondering how to set permissions on an element in clearcase under unix. You can’t just use your normal chmod. After reading “Phil for Humanity” I had the answer:
cleartool protect -chmod 550 myscript.sh
Quite simple after all. Your file, in this case myscript.sh, will now have the permissions you want.
Remember however, if you try to set write permissions on a file element, it wont set. The clearcase man page for protect advises that write perms are ignored – instead to obtain write permission to a file element, it must be checked out.
