clearcase note

 From my past installations on Solaris, you have to:  
 install it on global zone (for the mvfs part to install properly and be available for all the ngz)  
 install it on the non-global zones you need ClearCase  
 ClearCase won't be able to access all the paths it needs during the installation in an ngz, hence the first install on global zone.  
 See, for instance for CC8.0: "Installing Rational ClearCase to support non-global zones."  
 Install and configure Rational ClearCase on the global zone before you install and configure it on any non-global zones.  
 If you plan to run dynamic views on a non-global zone, the MVFS must be installed on the global zone on that computer. Specifically, this means that you cannot choose the ClearCase Server-only Installation option when installing Rational ClearCase on the global zone.  
 I never experienced a lack of performance because of being in an ngz, provided you reserve the appropriate quantity of resource (disk, memory) to each ngz.  
 I never used ClearCase in a global zone only, since I needed to start/stop ClearCase in each ngz independently. Hence my requirement for having CC in ngz, not just in global zone.
