Hello,
I have a shell script which has the below lines

Quote:

#!/bin/ksh
SHELL=/usr/bin/ksh;export SHELL
EDITOR=vi
export EDITOR
ORACLE_BASE=/database_1/oracle
export ORACLE_BASE
ORACLE_HOME=/database_1/oracle/product/9.2.0.8
export ORACLE_HOME

after I execute the shell script.. it doesnt throw any errors but I see that env variables are not set as in the script .. if i run the same commands outside the script, its working fine without any issue ..

What could be the issue .. ?

Please advice,
-Sai

How do you see that?
Copy and paste what you execute.

This problem & solution have NOTHING to do with Oracle.
>What could be the issue .. ?
PEBKAC for sure.
You need to source the file not execute it.

To source a file, you put a DOT (.) and a SPACE before it on the SH / KSH / BASH command line.

Instead of:

set_vars

do this

. set_vars

Hi.

When you execute this script, system will open sub shell(ksh) and set your environmental variables.

These environmental variables can`t be used by your login shell.

If you want to set permanently then you need do this in your environmental files.

What is your login shell?

to check your login shell just execute
echo $SHELL

Thanks.
