that looks good to me, once you created this pool, you need to assing it to fuctional alias “TN”.
make sure:
a.) you have created the tablespaces required for TN, by using DB configurator (in wm 7.X or later).
b.) Your DB is up and running, probably you can try to access though some client application like sqldeveloper, toad etc.
