CentOS 6: Set up Oracle Instant Client and Python package cx_Oracle

# NOTE: Oracle requires at least 1176 MB of swap (or something around there).
# If you are using CentOS in a VMWare VM, there's a good chance that you don't have enough by default.
# If this describes you and you need to add more swap, see the
# "Adding a Swap File to a CentOS System" section, here:
# http://www.techotopia.com/index.php/Adding_and_Managing_CentOS_Swap_Space
# Install basic dependencies
sudo yum -y install libaio bc flex
echo "Now go get some the following two RPMs ..."
echo "- basic: oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm"
echo "- SDK/devel: oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm"
echo "... from this URL: http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html"
echo "WARNING: It's pretty annoying, they make you sign up for an Oracle account, etc."
