Oracle Enterprise Manager 12c Release 4

Tue, 2014-06-03 10:48

Funny how there is no mention of the name “Cloud Control” in the latest announcement. Does that mean we are back to calling it just Enterprise Manager again?

Anyway, the latest instalment of EM has been born. The downloads are available on OTN.

I’ve got mine downloading. The past few versions have been relatively easy to install on a clean system, but the upgrades have been a total pig. I’m hoping this one is going to be significantly easier… Sucker… :)

Cheers

Edge of Tomorrow

Sun, 2014-06-01 12:31

I went to see Edge of Tomorrow today.

You will see reviews that say it’s a Sci Fi version of Groundhog Day, and that is kind-of true, but in a good day.

It’s not overly endowed with plot, but it’s a pretty good Sci Fi flick. I think from now on Emily Blunt should be in every film!

Cheers

UKOUG Operating System and Storage Event : Summary

Wed, 2014-05-28 15:19

Today was the UKOUG Operating System and Storage Event. I was a tourist for this event, as I didn’t have any presentations to do. Added to that, I’m a grunt DBA, so I wasn’t too sure what would be waiting for me at an OS and storage event… :)

Thanks to the miracles of Google Maps, I managed to be late for the event, so I missed the first session. Why is it I can get to foreign countries on time, but I can’t get to something that is pretty much in my own city without getting lost?

I bumped into a few people I know there, including Jason Arneil and Martin Nash and a couple of my colleagues. :)

First up (for me) was “Patching Linux with Spacewalk and Ksplice” by Wayne Lewis and friends. Spacewalk looks kind-of neat. It’s a free open source product, with Oracle’s version of it available from public-yum.oracle.com. Basically, it allows you to easily set up a local repositories, manage and track OS package updates across your Linux infrastructure. You can use it for free, or if you want you can choose to buy support from Oracle. The choice is yours. The second half of the session was on Ksplice, which I’ve known about for a long time. As it turns out, my understanding of what Ksplice actually does was quite off the mark, so it was good to be educated… :)

Second up was “Bringing OpenStack to the Cloud” by Stephen Bourke and friends. OpenStack is used to build public and private clouds. That is honestly as much as I actually know about it. :) This session discussed what OpenStack is and talked about Oracle’s implementation of OpenStack. You can read more about it here:

What was most refreshing about Oracle’s implementation of OpenStack is they are keeping it open. At a time when other OpenStack vendors might be trying to provide ClosedStack, Oracle are staying true to cause.

Next up was “Dtrace in Linux and Solaris” by Mike Carew. I’m not one of those guys that spends my life using Dtrace, strace or systemtap, but occasionally you have to get down-and-dirty, so it is good to keep on top of this stuff. Some great strides have been made to bring Dtrace to Linux, but it is still quite limited in comparison to the Solaris implementation. Perhaps as it matures we might get a feature like this on Linux, which I learnt about for the first time today!

“Virtualisation Case Study – How Not To Do It!” by Philip Brown was interesting as it was almost the polar opposite to my feelings about virtualisation. In fairness to him, this was a presentation of how not to do it and ultimately he did make the point that if you do it badly you are going to have a bad experience, which is definitely true. My counter to this is, if you do it well you are going to have a good experience. :) It’s all about using virtualisation where it is appropriate and knowing what you are getting into before you make that leap. Due to me not being able to keep my gob shut, there was a prolonged discussion about this topic after the session, which was fun. You can of course read my thoughts on virtualisation in this article.

I really enjoyed the day! Well done UKOUG and to everyone I saw presenting today. I certainly came away with a lot of good stuff to think about…

Cheers

Tim…

Godzilla

Mon, 2014-05-26 17:01

OMG (Oh My Godzilla)! What a total pile of steaming, festering dog crap! It is incredible how they managed to spend $160 Million and produce something with less credibility than Sharknado, which only cost $250,000!

I really don’t think it has any redeeming qualities. How, in a world that brought us Cloverfield and Monsters, can so much money be spent on such a worthless pile of guff like Godzilla. In my Cloverfield review I mentioned how bad the previous spin of Godzilla was. This respin is no better.

I really can’t be bothered to explain why it was such a putrid pile of excrement. Who the hell gave this 7.3 on IMDB? I would rather watch Pacific Rim, and that was total toilet as well…

Cheers

X-Men : Days of Future Past

Mon, 2014-05-26 16:34

This morning I went to see X-Men : Days of Future Past. It was very cool!

Don’t get caught up in the whole time travel thing. It really isn’t a big deal in the whole scheme of things.

My favourite characters were Blink and Quicksilver. Evan Peters plays Quicksilver, who has one of the coolest scenes in the whole movie. Bingbing Fan plays Blink. You don’t see too much of her in the film, but what you do see is awesome.

Hugh Jackman looks like he came from the planet steroids. He’s always in good shape for these films, but this was something else. Either there were some visual effects in operation, or there are performance enhancing drugs involved.

If I had to criticise one thing, it would be James McAvoy. I think he’s a good actor, but he tries too hard in this film. It feels forced to me…

Anyway, well worth the money IMHO!

Cheers

Oracle Midlands : Event #3 Summary

Wed, 2014-05-21 12:58

I really enjoyed Oracle Midlands Event #3 last night. Christian Antognini spoke on “12c Adaptive Query Optimization” and “Row Chaining and Row Migration Internals”. I certainly learnt a lot, which is the whole point of this stuff!

After the event a few of us went across to a local pub and the geek talk continued. Cool++.

Thanks very much to Christian for coming all that way to speak to us. Thanks to those good people at Reg Gate for sponsoring the event. Thanks also to the Oracle ACE Program for letting Christian come to visit us. :)

The next event is on Monday 14th July. Hope to see you there!

Cheers

VirtualBox 4.3.12

Sat, 2014-05-17 06:37

VirtualBox 4.3.12 was been born yesterday. It’s a maintenance release, so a number of things have been fixed. The downloads and changelog are in the usual places.

Seems to install and work fine on Mac, Linux and Windows. :)

Cheers

Oracle ACE Director Self-Evaluation

Tue, 2014-05-13 16:38

I’ve just filled in my Oracle ACE Director Self-Evaluation…

The way the tour dates worked this year, I got the LAOTN 2013, Nordic 2013 and Yathra 2014 tours in a single assessment year, plus all the one-off events. It looks crazy-busy… :)

Most of my events this year have been packed into the first half of the year, so I think next years assessment will look a little sparse by comparison…

Cheers

UKOUG Next Gen

Tue, 2014-05-13 04:36

I’ll be at the UKOUG Next Gen event at Birmingham City University on the 15th May.

My session is on “The Importance of Community”. I guess my blog readership is not exactly target audience for an event like this, but if you know any students or recent graduates who are looking to start a career in IT, or you are an employer looking for fresh new talent, you should come along to the event.

Cheers

Tim…

Sometimes it is just a coincidence!

Sat, 2014-05-10 07:35

Yesterday I was making a small config change to some test WebLogic domains. The change required a restart, so that’s what I did. The domains didn’t start up properly…

Being the last person to change the config, it was obviously something I had done that had broken them. I did the usual stuff of checking the log files and noticed some messages about not being able to write to a swap file. I did a “df -h” and noticed the mount point for the WebLogic installation was full. A quick bit of clean-up and everything started up fine.

So the moral of this story is one of the following:

  • Sometimes it is just a coincidence.
  • Don’t forget to configure your log rotation properly.
  • Never change anything in case it screws up and you get the blame.
  • “Just blame it on the guy who doesn’t speak English. Ahh, Tibor, how many times you’ve saved my butt.” ref

Cheers

Oracle 11gR2 and 12cR1 on Oracle Linux 7 beta

Mon, 2014-04-28 12:00

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…

Cheers

RHEL7 and Oracle Linux 7 beta

Wed, 2014-04-23 03:15

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.

Cheers

Some new Oracle Database 12c Articles

Tue, 2014-04-22 12:18

I’ve recently put some new Oracle 12c articles on the website.

The privilege usage stuff is really cool. Normally, trying to figure out what you can remove from a user is always a complete pain in the ass. Some of the databases I’m currently working with have used GRANT like it’s going out of fashion. Trying to identify what is really necessary is a tough job. Features like this are going to be hard to wait for…

Cheers

Tim…

Divergent

Mon, 2014-04-21 17:16

I’ve just got back from watching Divergent. It is a really good film!

Don’t believe any bullshit comparisons to that crappy Hunger Games. It is so much better than that rubbish! It’s probably a good idea not to read any summaries of the plot either, since it sounds kind-of stupid on paper. In the film it makes a lot more sense and just works.

Very pleased I went to see it. One of the better Sci Fi/action films I’ve seen is quite a while. Much more worthwhile than that spider-thing…

Cheers

The Amazing Spider-Man 2

Sat, 2014-04-19 13:26

I’ve just got back from watching The Amazing Spider-Man 2.

Wow, that is one seriously long film! At 2 hours and 22 minutes, it’s a good 1 hour and 22 minutes too long…

I guess there are two sides to this film:

  1. Action Scenes: During the action this films it is brilliant. Really over the top stuff. Bright, flashy and really cool.
  2. Everything Else : I don’t give a crap about character development in an action film. This re-imagining of the franchise is turning out to be even more whiny than the Toby Maguire version.

The film really could have been edited down massively and I would have come out agreeing with the film title. As it was, it’s “The Amazingly Long and Whiny Spider-Man Too!”

Cheers

Running scripts in CDBs and PDBs in Oracle Database 12c

Sat, 2014-04-19 09:23

You’ve been sold on the whole concept of the multitenant option in Oracle 12c and you are launching full steam ahead. Your first database gets upgraded and converted to a PDB, so you start testing your shell scripts and bang! Broken! Your company uses CRON and shell scripting all over the place and the multitenant architecture has just gone and broken the lot in one fell swoop! I think this will end up being a big shock to many people.

I’ve been talking about this issue with a number of people since the release of Oracle 12c. Brynn Llewellyn did a session on “Self-Provisioning Pluggable Databases Using PL/SQL” at last year’s UKOUG, which covered some of these issues. More recently, I spent some time speaking to Hans Forbrich about this when we were on the OTN Yathra 2014 Tour.

Today, I put down some of my thoughts on the matter in this article.

Like most things to do with Oracle 12c, I’m sure my thoughts on the subject will evolve as I keep using it. As my thoughts evolve, so will the article. :)

Cheers

KeePass 2.26 has recently been released. I would suggest going with the portable version, which is an unzip and go application.

If you want to know how I use KeePass, check out my article called Adventures with Dropbox and KeePass.
