Finally, I have completed the download of Oracle Database 11g and installed it in Oracle Enterprise Linux 4. This is the first copy of Oracle Database 11g that I have installed and seen it running live. To uninstall Oracle 10g R2 is simple for me. I just have to delete all the Oracle directories and files. The Database Control looks much cleaner than after I have installed Oracle Database 10g R2. It is time to download Oracle Database 11g and try the features that you want to try.
