If you want to use the DBCA then Demitre and Hans have told you what you have to do. You do have the option of performing a manual upgrade. Stop the existing db, set your environment to the new Oracle home, startup upgrade. Run the scripts specified in the Installation and Upgrade instructions. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Nisha Mohan Sent: Monday, August 27, 2012 4:31 AM To: oracle-l@xxxxxxxxxxxxx Subject: DBUA - PRKH-1014.Current user "ora11203" is not the owner user Hi, I am trying to upgrade 10.2.0.4 DB to 11.2.0.3 using DBUA. 10g oracle is owned by user ora10gr4 and 11g oracle is owned by user ora11203.
