Very much so.  Apparently Oracle is now recommending Linux for most systems (~70%) instead of using Sun or other vendors.  oracle.com is entirely Linux based (iAS system on Oracle RAC Linux machines).  Also from what I was told, their development databases are now all Linux.  

If you've ever seen an Oracle RAC (Real Application Clusters) on Linux perform, it's VERY impressive.  The caching and speed optimizations are extremely nice, especially when you tie that to a SAN and consider the failover capacity and other things that come with the RAC system.  I'd definitely recommend looking at it more.  

Another example - I ran some stress tests a long while back on a Linux box running Oracle (I think it might even have been 8.0.5 at the time) and I had like 1700 connections all doing heavy transaction processing and querying stuff at the same time.  It was slow grant you, because it was taking at least 2MB per connection, even with MTS.  It started swapping HEAVILY, but it still ran perfectly fine (just took 10 minutes for a simple select statement).  If you don't swap on Oracle, it's a pretty nice system.

Anyways, the Oracle RAC system allows you to plug in "Nodes" of linux machines as needed to scale.  It also allows for any of those nodes to fail and the database to still run transparently to the user.  We ended up buying a Sun V880 here and I'm thinking now we should have looked at the Linux/RAC system instead.

And the best thing is right now there's (to my understanding) a site license at the University to use the database software itself.  Makes it nice and cheap :)
Cheers!
