upgrading from 11.2.0.1 to 11.2.0.3

Hello,
I'm trying to upgrade from 11.2..0.1 to 11.2.0.3.  I need to do an "in-place" upgrade.  I've followed the instructions closely.  I've backed up the current oracle to a different location.  I've run the installation, and selected software only.  after that, I've restored the original config. files.  But when trying to perform the upgrade, it can't connect to the database.  I keep getting this error:

ERROR:
ORA-12547: TNS:lost contact

I get that error when trying to connect via sqlplus. 

am I missing something somewhere?

thanks in advance

Rae
