I distinctly remember downloading ORION for Solaris SPARC towards the back end of last year/beginning of this year via www.oracle.com/downloads but cannot find it there now. Nor can I locate it through ISP/MOS -> Patches and Updates. I can find the 11gR2 documentation for it on docs.oracle.com (http://docs.oracle.com/cd/E11882_01/server.112/e16638/iodesign.htm#CACJEEDI). Is ORION still available for download? If so, where?
Thanks for the pointer. SLOB looks interesting. I only require the low-level IO generation for performance measuring. It looks like SLOB has this feature so I'll check it out and see how it compares to other tools such as vdbench & filebench.
