Single Writer Lock and hp-ux
I found a White paper about Single Writer Lock on Solaris.
http://www.solarisinternals.com/si/reading/oracle_fsperf.pdf
Does the issue affect hp-ux or not ?
Online-JFS(Direct I/O) or Veritas Quick I/O avoid the issue ?
I think the whitepaper explains general issue of Unix Filesystems(UFS,VxFS).
Best Regards,

Re: Single Writer Lock and hp-ux
Is IO really the bottleneck of your database?If yes, then tune it, if not , why bother tune it?
Sun has Concurrent DIrect IO which solve the single write lock, and AIX has CIO also solved this problem.
Wonder whether HP will also have a release of such support.Since now HP by default used vxfs, I think Veritas will not release such a product which will compete with QuickIO.
