Setting envrionment variables through .bash_profile and oraenv

This is a very convinient way to set envrionemnt variables for Oracle in TEST envrionment. (For critical production envrionment, I still recommend to set Oracle envrionment variables explicitly using export)
Add following lines to ~/.bash_profile (for ksh/sh, add it to ~/.profile)

ORAENV_ASK=NO
ORACLE_SID=prorcl

. oraenv
