RE: Docs, Links, Good Books on Performance with RAC 10.2 / Solaris 10 ? ....... Veritas CFS(SFRAC) or QFS ? which FS to choose for RAC Benchmark ?

Thanks so much Anjo for the support.



For the upcoming Benchmark with Solaris 10/RAC Oracle 10.2, we need to
define the "File system" setup.



Seek your advice on the following:-



Qs 1 Is QFS Certified for Solaris 10/Oracle RAC 10.2? Seemingly it has
been certified last year for Oracle 9i.



Qs 2 Which is advisable - Veritas CFS (SFRAC) or Sun QFS?



(i) Does QFS support Low Latency Protocol (LLT) or the default User
Datagram Protocol (UDP) only?

NOTE - Veritas CFS (SFRAC) does support LLT.



(ii)) Is QFS in use at Large Production RAC 10g Sites?



(iii) Do both QFS & Veritas CFS(SFRAC) support Concurrent IO [CIO] i.e.
multiple threads can simultaneously perform reads and writes on a shared
file?

NOTE - CIO is available with JFS2 Filesystem from AIX.



 Qs 3 What is the Effort needed to switch from Veritas CFS(SFRAC 4.1 or
5.0{if certified too}) to QFS & vice-versa by using a baseline UFS
database in case of Bugs/performance issues on either?



NOTE - RAW, ASM are being avoided for now.



Thanks indeed



Vivek
