Solaris's sparseness

Coming from years of working primarily on Linux, one of the things that keeps getting me about working on Solaris 9 is just how sparse and bare a Solaris install is. I especially feel this with system diagnostic tools, where about 90% of the things I am used to considering as routine are either third-party packages or just not available.

(Solaris 10 holds out the promise to be much better, with things like DTrace, but I'm stuck working with Solaris 9 machines at the moment.)

Some of this is just different names for the same stuff (for which the Rosetta Stone for Unix is very handy), but for a lot of it you really need to start installing third-party software. (Even when semi-substitutes are part of Solaris; fuser is only a pale shadow of lsof, for example.)

And sometimes there doesn't seem to be anything at all. For example, my current desire is for something to dump system level file locking information, because I am trying to run down a peculiar Samba and NFS locking problem and I would sorely love to be able to see what processes have certain files locked, and how. On Linux I would use lslk; on Solaris, well, the core author of lslk dropped it in 2001 or so.

(Yes, I can find the source code. Last updated for Solaris 8. My quickly hacked attempt yielded no useful results.)

Sidebar: an inexplicable omission from Sun's Freeware stuff

Much to my surprise, Sun's Freeware software collection inexplicably does not include gdb, despite having the GNU compilers. Sure, Solaris has mdb, so you can at least do some state analysis of errant daemons with gcore and it (if the stars are right), but it's not quite the same.

Knowing about pstack would probably have saved me some time a few days ago, though. Moral: I should always check the Rosetta Stone before proceeding to brute force.

(Not that it would have helped; all of the Samba daemons confuse pstack as much as they confuse gdb and mdb. Oh well.)
