RE: Veritas CFS or QFS ? Which for High Hybrid Transaction Load Benchmark on RAC with Solaris 10/Oracle 10g ?

Zhu Chao, Folks,  

Other than for manageability convenience, How is a Big 4 TB NON-RAC "UFS" mounted Database to be converted into a RAW device based RAC database?  

Is there any option Other then export from mounted Database & import into RAW Database?  

Hence RAW is being avoided for now.  

Thanks indeed

Why'd don't you take raw volume?
Dealing with veritas volume manager, it does not make much difference between creating a datafile on filesystem, and creating a datafile on a volume

For an upcoming High Hybrid Transaction Load Benchmark on RAC with Solaris 10/Oracle 10g, need to define the File system setup  

Qs Is QFS Certified for Solaris 10/Oracle RAC 10g?

Qs If certified, Is QFS being used at Large Production RAC Sites

Qs Which is advisable - Veritas CFS(SFRAC 4.1) or QFS ?  

Any Docs, Links, advisable Books for the same please?  

RAW is being considered only as a last resort & ASM being avoided for now as it is still seemingly NEW & probably NOT so much tried & tested as yet with High Load Production sites.  

Config info:-

Approx 20,000 Concurrent OLTP sessions will be spawned

Num of Database Server Nodes = 4

Each DB Server Node = 28 CPUs

Oracle Shared Servers will be used

DB Size = 4 TB  

Will provide any Clarifications, Thanks indeed.
