Re: Linux Vs Solari

Hi,

RHEL4 can handle up to 32 x86 cpu's or 64 IA64 cpu's.

RHEL3 handle 16 or 8 IA64.

No need to buy veritas FS to use oracle RAC, you can use OCFS (of course veritas is in a different league...)

As for oracle and linux every thing we will say is better in linux some others can say it's better in solaris, this issue can't really be

resolved.

just do you tests, you can find out that the performance are better for you applications (or not).

i can say that in every thing that we moved to linux, we got better performance (apllication servers and databases).

Regards,

Oded.
