Every so often I have a nose around the contents of the Oracle Linux public yum repositories and guess what I found in the OL7.1 base and OL7 latest repositories.
The datestamps suggest they’ve been around since the 5th February, but I think these only became available with the release of OL7.1.
On the positive side, this means installations of 11g and 12c just got a whole lot easier on Oracle Linux 7. On the downside, I’ve got some minor rewrites to do.
I just did an upgrade of my old desktop from Fedora 20 to Fedora 21. The process was similar to this old blog post, but there were some variations, so I’ll list the procedure here.
It seemed to go fine!
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 126.96.36.199.
The installation process of 188.8.131.52 on the production release of Oracle Linux 7 hasn’t changed since the beta. The installation of 184.108.40.206 on Oracle Linux 7 is a lot neater than the 220.127.116.11 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 18.104.22.168 installation at the bottom of the 12c article, but now 22.214.171.124 is available from OTN there is really no need for someone to be installing 126.96.36.199 other than for reference I guess.
With all the excitement around the release of Oracle Database 12.1.02, it’s easy to forget that there is other stuff going on as well.
I’ve just noticed that Oracle have announced the release of Oracle Linux 7. You can download it now from eDelivery.
Just remember, it takes quite a while to get products certified on this stuff, so although I’ve already tried installations on the beta versions, I would not install any Oracle products on this stuff “for real” until the official certification is announced for each product.
A few months ago I wrote about some MySQL on Oracle Linux migrations we were working through. It’s been a long time coming, but last weekend was the go-live for this batch of migrations. So far so good!
Most of the elapsed time since my last post on this subject has been spent with the developers and users testing the migrations.
The process has taken a bit longer than some people would have liked. Rather than doing a quick and dirty upgrade, I’ve been pushing to get things done properly. Since I was the person who set up the infrastructure, I’ve been extremely anal about levels of privilege I’m granting. This has caused some minor rewrites of applications, which were essentially relying on admin privileges to perform some actions. Not any more!
I’m no MySQL guru, but I think what we have now is pretty darn decent, especially compared to where we started. I guess time will tell how bold a statement that is.
Onwards and upwards…
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…
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.
I’m in the process of taking on some of the MySQL databases in my company. The first ones are MySQL 4.1 running on Windows, so we are upgrading them to MySQL 5.6 on Oracle Linux. As with many of our systems, these will be running on VMware virtual machines.
Since the current installations are so old, we are planning on dumping out the data and creating fresh installations on the new systems. Based on the advice I got from Ronald Bradford and Sheeri Cabral, we are also taking this opportunity to switch to InnoDB and utf8, rather than MyISAM and latin1 that are currently used.
We are using the MySQL yum repository for the installation, so we can be on the latest MySQL version, rather than that shipped as part of Oracle Linux (or RHEL) 6.5. The other neat thing about this is it takes care of point release upgrades as part of the “yum update” process.
So far all my testing has been done on VMs running on my PC, but we are soon going to start rolling this out. It should be an interesting piece of work. The developers are doing a bunch of testing with InnoDB and utf8 to see what issues we come up against…
Update. For those new to MySQL, you might like to read this post by Patrick Hurley.
For those of you using Oracle Linux with UEK3, here are a couple of important blog posts that may have passed you by.
Following on from my recent batch of “what I’m doing at the moment” style posts, I just thought I would mention some of the infrastructure I’ve been installing and configuring recently…
We are still part way through a migration from Oracle Application Server to WebLogic 11g. There are many applications to migrate and test, fortunately not by me, but they fit into two main categories.
Some of our high profile applications of each type are already running in production on WebLogic and the general feedback has been very positive. I guess most of this comes down to the hardware refresh.
There are still a few more apps to migrate, but everything is pretty close to the end of testing now, so hopefully it won’t be long before we can say a not-so-fond farewell to Oracle Application Server!
All of these WebLogic installations are running on top of Oracle Linux 6 inside VMware virtual machines. So far we’ve seen nothing untoward about this setup and I would have no reservations about recommending this approach to others.
