Hi Joao.
The output you showed about the inventory is your target release and the point of your SCN message was to address the invalid objects so I am not sure to understand the relevance of the target inventory.
I am confused by your statement "Now everytime I type de command sqlplus /nolog it show me the 11.2.0.4 version." As you havent yet run dbua, you shouldnt have yet pointed the env to the new binaries...
I see you had another problem in Error when I start the DBUA (oracle upgrade) - powershell script
I can only suggest you double check your environment variables ORACLE_HOME_SRC ORACLE_HOME_TGT
I will have to step out this SCN thread as I'm quite confused by your problem, (I am not a DBA by trade and I havent done an upgrade from 10.2.0.x to 11.2.0.x for many years), I hope some people will provide you help otherwise, I'd suggest browsing the articles in support.oracle.com
good luck to you!
best regards
