Hi, i have a noob question
i have a linux with 3 instances all of them are with the same owner "oracle"
but my problem is to know how to change between those instances.
in windows system is using
Set oracle_sid instance1

but i dont know howto do it on linux system.
because i have a lot of variables like oracle_home, oracle_sid

export ORACLE_SID=instance1

instead of the set. The same for other environment variables.

And it's case sensitive in Unix/Linux.

you should define three environment variables:
using export commands.
export PATH=
export ORACLE_SID=
but the others is the same if your three instances are the same version

Yes, but set in user default shell profile.
check default shell
$ echo $SHELL
most properly it is ./bash profile
set parameter "oracle sid, oracle home , path" in .bash profile.
