Are There Large RDBMS Using Linux?

Jason Perlow of Linux Magazine writes:" With all of the recent computer press coverage of Amazon and Intel converting their web servers and other front end application servers to Linux, many of these stories neglect to mention that the back end systems these companies use still rely on commercial Unixes like Solaris, AIX and HPUX to host their RDBMSes (Oracle, DB2, Sybase, Informix) for their mission critical transactional applications and data mining. Are there any companies out there actively using Linux to host a mission-critical RDBMS ^? or looking to replace UNIX with Linux for this purpose?"

to answer your question, i dont know of any.

i myself am in the datawarehouse of a large international company, our DWH is run off IBM as400's with DB2 + essbase/hyperion.

there are several factors why there will be no change in this.

IBM offers complete intergrated solutions (HW+SW) that you dont get with opensource solutions.

the opensource rdbms cant compete with the likes of DB2 and Oracle in terms of scalability and features.

3rd party integration. (Esssbase/Hyperion) database cube solutions dont exist for linux/freebsd. (man 3d cube db's are funky)

stable cross platform ODBC drivers, (winnt drivers for ASP, JODBC java+websphere, AS400 + RS6000 drivers)

support. (who gives 24/7 support on postgress, and send out tech support guys giving consultations, will come on site on a sunday at 4am?)

what OpenSource rdbms provide true mutli language support (we have records in cryllic, japanese, american, german, etc)?

high availablity (i dont know the current state of HA functionality in the linux kernel)

Linux on the AS400 is not seen as providing anywhere need the requirements at present, and its opensource database solutions are same.

(and i dont even think there is any cube database products in the opensource area... ???)
