Using Solaris 10 and PostgreSQL to Improve Data Warehouse Performance

Wanted to call your attention to an interesting data warehousing customer success story describing one customer's transition to PostgreSQL from Oracle 8i and reasons why they chose to deploy Solaris 10 rather than running Linux for their implementation.

You might note, OmniTI's initial reasons to move to an open source solution from Sun were based on skyrocketing software licensing costs and stability issues they were experiencing at the Linux kernel level. Once this migration was complete they found some other benefits: improved database performance without increased licensing costs and a stable computing environment.

Theo Schlossnagle, OmniTI principal and CTO described the situation in his personal blog, noting Solaris, with its ZFS file system and dynamic tracing (DTrace), does "really mesh well with core database needs".

Rodney Gedda wrote about it for Computerworld: "Sun-PostgreSQL win takes swing at Linux, Oracle - Frequent Linux crashes drove consultant to Solaris" profiling "a large database marketing firm" and its transition from Oracle to PostreSQL and how it chose Solaris 10 over Linux, based on a Sun/OmniTI case study.
