Professional use
We have a network of about 130 Oracle databases monitored with 6 Grid Control servers so it isn't an adventure playground!
I have been considering your advice and to be honest, Oracle support could be the only way ahead. I'm loath to take that approach for a solution that will probably only take 5 minutes for a professional Linux admin to resolve, but that why they get paid the wages!
RHEL is the best platform I think as far as support goes, much more I can't judge at this moment. To be honest, I think it is problems like this that prevent most admins from even attempting the Linux route.
I find it ironic though that I need the support for an OS that (I thought) was inherrently simple to use. The most complex part, the database, will probably not see a support call from me!
Thanks for your advice Neon!
