Oracle XE 10g beta public release

Oracle is launching step 2 (InnoDB was 1) in messing with MySQL with the launch of Oracle XE.
XE is free to use and free to distribute. Perfect to bundle with small software packages or when developing a website that needs scalability. Oracle guarantees application compatibility with SE/EE versions of Oracle.

I also think that the release of XE will bring more light to the cute little tool HTMLDB, for those of you who are not familiar with HTMLDB it is more or less an application server with a built in IDE. You can create a small web based application in the matter of minutes. Perhaps a small reporting interface or a timesheet system. A good example of a larger HTMLDB application is Ask Tom. Tom Kyte is by the way the main man endorsing XE. He is happily explaining how much better Oracle XE is than MySQL in this nice podcast.

Installing Oracle XE is a piece of cake on most systems, Oracle even acknowledge that it will work on Debian (spoke to benr on IRC and he mention that there where a few issues installing on Gentoo). A quick rpm -i and small config script sorted everything out on my Fedora Core 4 VM. Just connect. Well almost, the installer still has a few tiny bugs but those will probably be sorted before final release.
One annoyance is that there is no oraenv script in a decent path. The default env script is located in /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/ Perhaps not the best choice if you ask me. The whole idea of installing under /usr/lib seems a bit silly.
