Frequently Asked Questions about the Simplified HEPiX scripts¶
Frequently Asked Questions about the Simplified HEPiX scripts
In October 2011, the Linux Certification Committee agreed to a proposal to simplify the HEPix scripts for SLC6. These simplifications are implemented in version 4 of these scripts.
This page describes the main user-visible changes, and gives suggestions for end-users who miss certain functionalities. These suggestions could be implemented in the user's dot-files, or in the group-specific scripts under /afs/cern.ch/group/XX.
Your feedback is welcome at Linux.Support@cern.ch.
How to switch off HEPiX scripts altogether?
An "off-button" exists already in version 3 of the scripts. To completely disable the HEPiX script, simply run:
mkdir $HOME/.hepix
touch $HOME/.hepix/off

What about the Oracle environment?
Users who used to rely on the $HOME/.hepix/oracle file to set up Oracle-related variables can set them in the following way:
| Bourne-shell family | C-shell family |
ORACLE_CERN=/afs/cern.ch/project/oracle export ORACLE_CERN source $ORACLE_CERN/script/profile_oracle.sh |
setenv ORACLE_CERN /afs/cern.ch/project/oracle source $ORACLE_CERN/script/cshrc_oracle.csh |
