CMS Space Monitoring

This segment introduces how to use CRAB and the bugs of some CRAB versions I met when I do the tests on our UI.

The goals

There are two ways. one way is to use CRAB installed at CERN, the other is to install CRAB in our UI.
*Use CRAB installed at CERN:
1.The last version of CRAB is already installed at CERN, just do:
      source  /afs/cern.ch/cms/ccs/wm/scripts/Crab/crab.(c)sh
2.Then copy locally the crab.cfg file from dir $CRABDIR/python/crab.cfg.
*Use CRAB installed in cmsui01 or lcg003:
   1.download the last CRAB_X_Y_Z tgz archive from [[http://cmsdoc.cern.ch/cms/ccs/wm/www/Crab/download.html][Download]] or from the CERN afs server:
     /afs/cern.ch/cms/ccs/wm/scripts/Crab/      
   2. untar the tgz file in a directory "YOUR_DIR" of your UI
   3. run the configure file you can find in "YOUR_DIR"/CRAB_X_Y_Z/ from a clean shell: 
       cd YOUR_DIR/CRAB_X_Y_Z/
       ./configure 
   4. source YOUR_DIR/CRAB_X_Y_Z/crab.(c)sh.

The functions and realization

I have tried to install three CRAB versions in cmsui01. I am successful with CRAB_2_0_4, CRAB_2_1_2, but failed with CRAB_2_2_1.
*the following error found when I use crab_2_2_1 in lcg003
crab: Scheduler Session: 'Cannot create scheduler SchedulerGLiteAPI  \t \n         missing glite environment.\n         Try export PYTHONPATH=$PYTHONPATH GLITE_LOCATION/lib\n         No module named SOAPpy.Client'
*the following error found when I use crab_2_2_1 in cmsui01
Error: Unable to find pyOpenSSL module

*Please feel free to give some comments.
