One 10g downside: If on Windows, some tools like repca don't work and haven't been around long enough for support to admit it. Even if people complain, support calls about it are never resolved because people just wipe out everything and start over.

Both 902 and 904 are fragile in the sense you don't want to move or change much in the way of configuration once things are working. 902 is definitely worse in having to apply patch on patch on patch. There are some architectural differences between 902 and 904 that can make some things work very differently. I couldn't say whether that would affect any j2ee, unless it happens to access a database.

Happy Birthday, David Spade.  I'm sick of your commercials.  They're
