If you develop on the iSeries, or operate one, you need a shortcut to the iSeries DocFinder in your favorites list.

My shortcut is called 'INDEX 400', which tells you how long I've been using it!

The other must-have shortcut is to comp.sys.ibm.as400.misc - whatever problem you might have, you are not the first.

Prevayler looks like an interesting solution for small scale object persistence in Java.

There are a couple of articles about it over on Advogato.

The big problem with this so far as I'm concerned, is that everything is kept in RAM (like Gadfly). They can talk about Breakthroughs In Memory Technologyand servers with multi-gigabyte RAM, but I'm used to working with multi-gigabyte databases, and in the real world, you just don't have that kind of RAM available.

I'd like to give it a try for something small, though.

IBM has published an overview of the changes to DB2 on the iSeries at V5R2.

Personally, I'm most interested in the SQL enhancements. Views over unions will be useful, and identity columns will make a lot of jobs simpler.
