For Linux OS

Log on as the user for which you want to change the variable

Go to your home directory by entering "cd"

Enter "grep ORACLE_HOME .*"

Now you can see all occurences of ORACLE_HOME in the relevant files

Edit all files and change the entry to the desired value

Log off and on again

On Linux/Unix, the SAP users (sidadm, orasid) use the c-shell. A temporary change can be done by entering "setenv ORACLE_HOME <New value". The export command is used in another shell.

For Windows OS it depneds on the windows version, just do a google search on "Windows <Version> change environment variable".

at the command line level you can use:

export ORACLE_HOME=/oracle/SID/112_64 to ORACLE_HOME=/oracle/SID/121

If this is a reoccuring need, you should add this line to your bash .profile on the unix machine.

Your question is vague as to what you have access to.
