ASM is a requirement for SE RAC. Consequently any SE RAC customers on windows will be using ASM. When I was working for them the CPA applications for the Audit Commission (http://www.audit-commission.gov.uk/cpa/index.asp) were hosted on just such a RAC database, though that may have changed since. ASM worked just fine - this would have been 10.1.0.2 or 10.1.0.3 from memory - so even relatively early ASM was pretty good. I wouldn't personally have gone with ASM at that early stage if I'd had a choice, so take my comments above as an endorsement. As far as popularity of the platform goes, last I saw Windows users accounted for about 30-40% of Oracle's DBMS customers (by number not value). It wouldn't suprise me at all if windows+asm is rather more prevalent than (say) hpux+asm. cheers Niall On 8/31/07, Alex Gorbachev <ag@xxxxxxxxxxxx> wrote: > > Oracle on Windows... well this is more of a religious topic and I'm a > bit religious here even though I happen to administer few Windows > environments. :-) > > I don't have any experience with ASM on Windows (I wouldn't even think > that it works but apparently it supposed to).
