Cannot upgrade version 10 SDE geodatabase to 10.2.2

JamesStreet1

I have an SDE Oracle 11g geodatabase running on my server and just uninstalled arcgis desktop 10 and installed version 10.2.2. When performing a direct connect as the sde user and trying to run the upgrade geodatabase tool I get the message "This 10.0 geodatabase matches the ArcGIS release you are currently using" Anyone know what the problem might be?

Check the Bit level of the Oracle database. Starting from 10.1 only 64-Bit oracle databases are supported....so you cannot upgrade a 32-Bit oracle database to 10.1/10.2 or later.

SQL to check the Bit level of Oracle db:

Connect in SQLPLUS using a sys user and execute the below query

select
length(addr)*4 || '-bits' word_length
from
v$process
where
ROWNUM =1;
