I'm confused now. Are you saying that HACMP is clustering software? Or are you saying that AIX HACMP can support 32 nodes for DB2 without clustering? Then what's HACMP doing there? I mean, if DB2 doesn't need special clustering software but it runs on 32 AIX nodes *only* with HACMP, then exactly what is the definition of "special clustering software"?

So HACMP provides a substitute for clustering? And how does it do that transparently and with no overhead whatsoever? Smoke and mirrors?

If it's that "transparent", then maybe it is not needed at all?

Careful, it's getting mighty confusing...

BTW, I know what HACMP used to do. Had to deal with that three years ago during a tender for SAP and ORACLE on AIX. It didn't do as much as you're saying. And I still don't fathom why the heck does DB2 need it in AIX to run on 32 nodes. Unless it's gained a "clustering" feature that wasn't there three years ago?
