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

Well you could talk to me :-)

I did a 15K user RAC/OPS once.
