Oraenv doesn't seem to work

Question

Version : 11.2.0.3
Platform : Oracle Linux 6.3
oraenv doesn't seem to work as shown below. I haven't set ORACLE_SID in the .bash_profile as this server is going to have multiple DBs in future. So, I need to use oraenv script to set env variables.
Trying to source oraenv file.
$ . oraenv
ORACLE_SID = [oracle] ?
Ideally, it should prompt the SID listed in /etc/oratab file. So, in this case it should be something like
$ . oraenv
ORACLE_SID = [oracle] ? GRCFMS
Here are the contents of my /etc/oratab file and .bash_profile
# su - oracle
$
$
$
$
$
$
$ whoami
oracle
$ pwd
/home/oracle
$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi
# User specific environment and startup programs
#PATH=$PATH:$HOME/bin
#export PATH
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/dbhome_1
#export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$PATH:$ORACLE_HOME/bin:/usr/bin:/bin
$
My oratab file
$ cat /etc/oratab
# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.
# A colon, ':', is used as the field terminator.  A new line terminates
# the entry.  Lines beginning with a pound sign, '#', are comments.
# Entries are of the form:
#   $ORACLE_SID:$ORACLE_HOME:<N|Y>:
# The first and second fields are the system identifier and home
# directory of the database respectively.  The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
# Multiple entries with the same $ORACLE_SID are not allowed.

if in fact you did exactly as posted above, the su - oracle established a new process which knows nothing about the previous invocation of oraenv
BTW - never use OS "root" when dealing with Oracle DB
