11_2 Rac on NFS install question

Postby rjngh2005 » Fri Sep 06, 2013 10:50 pm

Hi Tim,

I am attempting an install of 11g R2 Rac using linux NFS

You have a line which reads as following

nas1:/shared_config /u01/shared_config nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0

i am getting an error saying
PROT-1: Failed to initialize ocrconfig
upon research I feel the solution is to include the

in the above line

what do you think ?

The recommended settings are published in MOS note [359515.1].

https://support.oracle.com/epmos/faces/ ... d=359515.1

The settings I suggest match those in the document for Linux x86-64, which is what I was using.

The noac is not a recommended setting for x86-64, but it is for the OCR/Voting location on x86. So if you are using 64-bit Linux, noac is not the solution.

The other thing to take note of is several people report really bad performance when using noac.
