In shell, I don't know a way to keep an Oracle connection opened (and I don't think there is a way, sqlplus does not support it!).
By the way, if you want this, why the first piece of code I wrote is not valid to you? It executes all queries in the FileName array sequentially, in the same connection!
If you really need to open the connection once, execute the queries and then close the connection, I suggest you to use another programming language.
My suggestion is:
Python and its lib to connect to Oracle:
cx_Oracle
Here is an example:

isympy(1) isympy(1)
NAME
isympy - interactive shell for SymPy
SYNOPSIS
isympy [-c | --console]
isympy [ {-h | --help} | {-v | --version} ]
DESCRIPTION
isympy is a Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that exe-
cutes the following commands so that you don't have to:
>>> from __future__ import division
>>> from sympy import *
>>> x, y, z = symbols("xyz")
>>> k, m, n = symbols("kmn", integer=True)
So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It is intended for easy and
quick experimentation with SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using
the "from sympy import sin, log, Symbol, ..." idiom).
OPTIONS
-c shell, --console=shell
Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise).
Example: isympy -c python
FILES
${HOME}/.sympy-history
Saves the history of commands when using the python shell as backend.
BUGS
The upstreams BTS can be found at <http://code.google.com/p/sympy/issues/list> Please report all bugs that you find in there, this will
help improve the overall quality of SymPy.
