Home -> Community -> Mailing Lists -> Oracle-L -> Re: 10g RAC - Cluster Ready Services
Hi,
I have the friend in Oracle.
I asked him is there any document for stupid DBA's as
I am where Oracle explaining in stupid way how to
install RAC on Solaris without any clusterware or
volume manager. He said you do not need anything of
course (old sales story).
When I insisted (even after reading all RAC books,
notes and who knows what) he asked further the chain
and at the end he was put on the hall of the shame for
asking something like that :)
I can imagine. In Oracle whatever sales said is true.
Anyway, I could not get rid of Sun Cluster because of 9i RAC. I installed 10g RAC a few times in the different way.
I think I did next, but cannot remember anymore, need
to check when back to work).
If you create the partition (raw device) in the same
way on the shared disks with format utility just one
raw device. Where you can point from both nodes to the
same disk/raw device and use it for CRS voting disk,
then I believe that is it.
Later on you can install ASM in the cluster mode as I
did. Also RAC on top of clustered ASM.
But again, because I have Veritas volume manager and Sun Cluster preinstalled on that machine, I cannot say that this is going to work on the flat Solaris (or other OS).
If you think that ASM is also using stupid format partitions (or created by some volume manager) then in the same way you can create one partition (raw evice) for CRS.
Does this make sense?

Zoran
