Remember that this is still 11g R1, sure it has been through an extensive beta testing phase but it has not being in the real world yet :0.
Let's look at the top then reasons (according to me) that you might want to upgrade:
- You want the latest and greatest toy to play with;
- There's one neat new feature that will solve all your problems;
- Your Oracle sales person gave you a free toy with the upgrade;
- You wanted to contribute to Larry Ellison's retirement package;
- You have nothing better to do at work;
- Your boss told you to do the upgrade;
- Tom Kyte/Jonathan Lewis/Insert Oracle Expert Here told you so;
- 11g sounds better than 10g;
- You want ensure that your Oracle E-Business Application version is in line with the database version (11i & 11g);
- You like the fact that it took 30 years to get to 11g.
Since 11g is not generally available yet, I would assume that CPU July 2007 is included in the base code. Regardless, I would think that once it is available, the OTN website will be busy with everyone looking to download the software. I for one, now that I have wiped Vista and install Linux on my new desktop will definitely be looking at installing 11g with the starter database to play around.
