In addition to work Oracle has done to make Solaris cloud-ready, the company has also closely tailored other Oracle products so that they can be coupled more easily to Solaris, including the Oracle Database 11g, Oracle Fusion Middleware 11g, and the Oracle Enterprise Manager Ops Center administrative software package. By controlling an entire stack of software, the company can make "holistic" decisions over which part of the stack would be best suited to tweak to gain performance improvements, Flierl said.
Solaris 11, which complies to the Open Group's specifications for Unix implementations, can support any programs that were written for earlier versions of Solaris, dating back to Solaris 6. The company also runs the Oracle Solaris Binary Application Guarantee Program, which certifies more than 11,000 applications that can run on Solaris 6.
Solaris 11, released Wednesday, will run on both x86 and Oracle's Sparc-based processors.
