Oracle 12c RAC on Oracle Linux 6 and 7 using NFS


linux-tuxFollowing on from the last post, I’ve brought my NFS RAC stuff up to date also.

I noticed I had not done a RAC install using NFS on Oracle Linux 6, so I threw that in for good measure too. :)

Just as a little history to this… I was doing the desktop Oracle RAC thing (using VMware then VirtualBox) for a while, when I started reading some blog posts by Kevin Closson about NFS. At the time, NFS filers were considered the poor relation to SANs, which was obvious or they wouldn’t be so cheap in comparison right? In those articles Kevin pointed out that most people’s systems at the time probably weren’t capable of maxing out a decent filer if it were set up correctly. Since NFS is a cluster file system, that got me thinking I should try RAC on it to see how easy it was. That was in the Oracle 10g days. How time flies when you are having fun… :)



Oracle 11gR2 and 12cR1 on Oracle Linux 7


I did a quick update of my Oracle installation articles on Oracle Linux 7. The last time I ran through them was with the beta version OL7 and before the release of

The installation process of on the production release of Oracle Linux 7 hasn’t changed since the beta. The installation of on Oracle Linux 7 is a lot neater than the installation. It’s totally problem free for a basic installation.

You can see the articles here.

There is a bold warning on the top of both articles reminding you that the database is not supported on Oracle Linux 7 yet! Please don’t do anything “real” with it until the support is official.

Note. I left the fix-it notes for the installation at the bottom of the 12c article, but now is available from OTN there is really no need for someone to be installing other than for reference I guess.





Oracle 11gR2 and 12cR1 on Oracle Linux 7 beta


I’ve been having a play with Oracle Linux 7 beta over the weekend. Not surprisingly my first thoughts were to install the Oracle database on it.

As expected, the installations were almost identical or Fedora 19.

I’ve put a warning on the front of the OL7 articles, but I’m sure it won’t stop some Muppets using it in production then trying to blame me. :)

I don’t know how long it will be until OL7 goes to production and I’m sure it will be a long time before anything is certified against it, but it’s always nice to see what’s coming… :) I’ll update the articles when anything significant happens…



RHEL7 and Oracle Linux 7 beta


Nearly two weeks ago, Oracle announced the Oracle Linux 7 Beta 1. Being the Linux fanboy I am, I downloaded it straight away from here.

Oracle Linux is a clone of the Red Hat Enterprise Linux (RHEL) distribution. The RHEL7 beta, and therefore OL7 beta, distro is based on a cut of Fedora 19, although depending on who you ask, it’s possibly more a mix of Fedora 18, 19 and 20… Suffice to say, there are a lot of changes compared to the RHEL6/OL6 distribution.

As I’ve mentioned several times before, my desktop at home is running Fedora 20, so I’m pretty used to most of the changes, but I’ve not written much about them, apart from the odd blog post. It’s not a high priority for me, since I’m not a sysadmin, but I’ll be updating/rewriting a few of the Linux articles on the site to include the new stuff.

When Surachart Opun mentioned having to look at systemd and firewalld, it seemed like the perfect opportunity to update my firewall and services articles. You can see the new versions here.

RHEL7/OL7 is only in beta, and even after the production release I’m sure it will be a long time before Oracle actually certify any products against it, but if you are not a Fedora user, it’s probably worth you having a play around with this stuff.
