Hello everybody.

I have to choose a RDBMS for my java apps and I'd like
to find one that meets the following:

1 - opensource
2 - table size limit independent of the undelying arch
3 - jdbc driver with support for updatable resultsets
4 - installation and configuration procedure well
   documented or easy like Firebird

Until now I've tried MySQL and Firebird.
Both seem to lack easy support for unlimited table size
due to the fact they use standard files, AFAIK. MySQL
offers the LFS solution to this, but
- it's not a clean solution as it requires at least
 a kernel rebuild.
- it is available only under Linux, so the table size
 limit still depends on the underlying architecture.
Moreover JayBird lacks support for updatable resultsets.

Is there anything that meets my requirements?
