Indeed, one of the more amusing stories was a Platinum Beta customer showing us some slideware from a certain company comparing their OS against Solaris. The slides were discussing available tunables, and the basic gist was something like: "We used to have way fewer tunables than Solaris, but now we've caught up and have many more than they do. Our OS rules!" This gave us a nice chuckle, since we've been trying hard to eliminate every tunable we can in the past few years. One of the best examples of this the SysV IPC tunables. Prior to S10, these consisted of a bunch of random (though sadly well-documented) /etc/system variables that everyone was forced to "tune" to do anything non-trivial. Thanks to Dave Powell, a large portion of these were made auto-tuning, and those that couldn't were turned into resource controls as Eric described. So if you want to add some tunables to Solaris, you should probably pose the question as a list of things you think need tuning, and we can help come up with a way to auto-tune them, or an appropriate interface for managing them. And as pointed out previously, /proc is _definitely_ not the right interface. - Eric -- Eric Schrock, Solaris Kernel Development. _______________________________________________ opensolaris-code mailing list [email protected] https://opensolaris.org:444/mailman/listinfo/opensolaris-code
