Re: [suse-oracle] 11gR1 RAC on SLES

Hi,

We're running 11g on SLES 10 SP2. We were initially on SP1, but did an
upgrade to SP2.

The install has a few gotchas, but I think oracle have fixed a few of the
issues (I had most problems with the clusterware layer).

I hit a few more problems with upgrading from 11.1.0.6.0 to 11.1.0.7.0, but
the system still runs okay (although the services have got a bit fried).

FYI, we're running two instances joined to an EMC SAN and are using ASMlib
(means you have to synchronise the asmlib driver and kernel version if you
want an oracle supported setup).
