Tanel, I don't know if you noticed, but whenever an OS or a database becomes adequately equipped with various diagnostic instruments, it ceases to exist or, at least, becomes obsolete. That has happened to VMX, MVS, GCOS and Dynix. Solaris has the best diagnostic instruments of all Unix variants and SUN has already become a white dwarf. All it needs is Ace Rimmer at the helm, to become a red dwarf and vanish. By that criteria, Linux is nowhere near obsolescence. It cannot even do I/O accounting per process. Oracle, on the other hand, has great diagnostic instruments, which instills fear in my heart.
