Fedora 11 and Oracle 11g…

 

It’s that time again where I check to see if Oracle installs on the latest version of Fedora. The result once again is yes, it does. The main website has the links to the articles. I would add links here only the browser on this internet cafe machine doesn’t support cut & pates. :)

When I get on a real computer I’ll put the links in this post as well. :)

This release of Fedora is probably quite significant as it is likely to be the base for RHEL6.

Fedora 10 and Oracle 11gR1…

 

I like to meddle with Fedora from time to time, just so I can see what’s coming round the corner in RHEL. I read recently that Fedora 11 will be the base for RHEL6, which means we are about 6 months away from seeing what the future of RHEL is going to be…

Much as I expected, there were no real problems getting Oracle 11gR1 running on Fedora 10. Here is an OS and an Oracle installation guide for Fedora 10.

The Fedora 10 network configuration dialog seemed to have a couple of issues/bugs. For a start, it was impossible to set the subnet mask. It was constantly overwritten by the default gateway. I adjusted it in the config file and it was fine, but it was a bit confusing for a while. :)

I’ve complained a number of times in the past that Fedora doesn’t seem to have an obvious direction. Is it server or is it desktop? Of course it’s both, but I think some clear intent helps from a marketing point of view. The fact that the Desktop Edition, a live CD, is at the top of the Get Fedora page will save many people form downloading a DVD full of software they will never need. Once installed, you get access to all the software via the “Add/Remove Software” dialog.

A few interesting things about the installation are:

  • The installation package list is fixed. There’s no customization during the installation.
  • The installer assumes you want DHCP for your network.
  • SELinux and the Firewall are on by default.
  • Services like SSHD are not on by default.

I guess if these issues annoy you, don’t pick the desktop edition. :)

I think this is definite step in the right direction as far as encouraging Fedora for desktop use.

PIVOT and UNPIVOT in 11g…

 

I’m trying to get back into the swing of writing again after my 2 month layoff. It’s a little daunting, but quite fun as well.

There’s a bunch of 11g new features that didn’t make it into the OCP exam, and the PIVOT and UNPIVOT operators fall slap bang into that category.

Pretty neat!

Oracle 11g RAC On Linux Using VMware Server 2…

 

I mentioned in a previous post I had taken the plunge and upgraded to VMware Server 2 on my laptop. Now I’ve also upgraded my main machine at home and it seems to be working fine. Probably the most complicated thing I run at home is a virtual RAC, so I wrote a new article to document the installation:

From a user point of view, the only difference between VMware Server 1.x and 2 is the new web-based managment interface. The VM setup itself is almost identical and as you would expect, so is the Oracle installation.

So far so good.

Oracle Certified Profesional (OCP) Database 11g…

 

I passed the Oracle Database 11g: New Features for Administrators (1Z0-050) exam today. It’s a bit of a relief because I feel like I’ve been preparing for this exam for a year. My first OCP revision article was written about 1 year ago, when I was hoping to be ready for the beta exam. Unfortunately, all the presentations and teaching I’ve been doing this year proved to be a bigger distraction than I’d hoped, which meant I missed the deadline for the beta exam, and overshot the start of the production exam by about 6 months. :)

Well, now the exam is over it presents me with some new issues.

1) There are some gaps in my revision notes that need filling. I did a lot of reading during the preparation, and pulled out the areas and facts I thought were most important. Based on the events of today, this didn’t necessarily match up with the contents of the exam. It didn’t affect me, as I had done the additional reading, but as it stands I think it’s touch-and-go whether my revision notes alone will get someone through the exam. This means I’m going to have to go through and revise a few of the articles to fill the gaps.

2) There are a couple of OCP revision articles I’ve not published yet. I got a little impatient and sat the exam before I had finished prettying them. They will follow shortly, conferences permitting.

Like all the OCP exams, this is just the first steps towards learning this release…

Cheers

PS. I suppose it’s a little premature to call myself an OCP 11g. I guess that’s not official until Oracle send through the certificate. :)

PPS. Before anyone asks, I used the Oracle manuals to prepare for the exam, so I can’t give certification guide suggestions…

Scheduler Enhancements in 11g…

 

The latest article in my OCP revision notes has surfaced:

The detached and lightweight jobs look fine, but I’m not totally happy with the remote external jobs. I don’t think they quite live up to their promise, and they seem like a security issue waiting to happen. I assume Oracle don’t expect you to use remote external jobs if you have grid control, or you will end up with a couple of agents on some servers. :)

Quite a glaring omission is the lack of integration of the new features into Enterprise Manager. For many people, if it’s not in Enterprise Manager, it doesn’t exist.

I’m hoping a few loose ends will get tied up in 11g Release 2.

Cheers
