This article is based on SAP note 1827566 – How to set environment variables for SAP system.
Setting the Environment Variables
On Windows environment

Right click on My Computer / This PC and select Properties.
Click on Advanced system settings.
Click on Environment Variables.
You can click one the following options, for either a user or a system variable:
- Click New to add a new variable name and value.
- Click an existing variable, and then click Edit to change its name or value.
- Click an existing variable, and then click Delete to remove it.
On Linux environment
Environment variables are set by login scripts. These are .cshrc, .profile, .login, depending on the login shell (csh, ksh, sh, etc.) of [sid]adm user. You don’t need to put anything there.
For SAP systems and its database environment variables are inserted in $HOME/.sapenv_[hostname].(c)sh and $HOME/.dbenv_[hostname].(c)sh scripts of [sid]adm user (e.g. /home/bcsadm/.sapenv_probud2.csh).
When variables are changed / deleted / added this way both SAP and (to be on the safe side) the SAP Start service (sapstartsrv) needs to be restarted.
Checking the Environment Variables

Right click on the server instance, select All Tasks and View Environment.
