Hi Gautam, re: > I was able to launch the configuration window, when logged on as > 'mcidas' and it gave me the same error msg, which is probably due to > Shared memory.

I think your problem is that the McIDAS environment variables that are set for this user are incorrect. > I have also created an temp account on our cluster, > so you can see the problem directly. I just logged on and confirmed that the McIDAS environment variables for the user 'unidata' were incorrect. The way things were setup, the McIDAS startup procedure was trying to access/modify the copy of MCGUISTART.BAT located in the ~mcidas/workdata directory. This directory is correctly to _not_ be writable by any user other than 'mcidas'. > In the '.bash_profile' of 'unidata' I have entered the various > required McIDAS environment variables. The settings of the environment variables in ~unidata/.bash_profile were not correct for a user that is _not_ 'mcidas'. I modified the content of .bash_profile to match the instructions in: Configuring a New User Account http://www.unidata.ucar.edu/software/mcidas/2005/users_guide/ConfiguringaNewUserAccount.html#22412 Outside of the need for a reboot to affect the shared memory change, things seem to work correctly (from the little testing I did).
