Data synchronization to mobile devices is not restricted to IBM relational databases: DB2 Everyplace supports IBM DB2 UDB8 (Universal Database), Cloudscape, Informix, Lotus Domino, Microsoft SQL Server, Oracle and Sybase.
Wanted: Beefy Server
DB2 Everyplace 8.1.4 requires at least a Pentium III with 512 MB of RAM (1 GB is recommended if you're using WebSphere as the application server). Although the server appeared to run fine on a machine with only 256 MB of RAM in my tests at our Green Bay, Wis., labs, running the Java administrative tools was painful.
For a Linux installation, you'll need to do a little work, including manipulating kernel parameters. The changes, which can be made with sysctl, include increasing file-handle maximums, shared memory and thread maximums. You'll also need to export your display if you aren't running X on the server. I did the install locally within X and administration remotely on a laptop running Mandrake Linux 9.1. Both methods worked well.
