Video: SQL Server Databases on Microsoft Azure

I mentioned in a previous post, the whole look and feel of Microsoft Azure has been rejigged. As a result, I had to do a run through of the SQL Server DBaaS stuff to update the screen shots in and old article on the subject.

Azure : SQL Server Databases on Azure

Since I was doing that, I figured I might as well do a video for my YouTube channel.

Video: Oracle Linux Virtual Machine (VM) on Micorosft Azure

The interface for Microsoft Azure has been re-jigged since I last did screen shots, so I did a run through of creating an Oracle Linux VM and recorded it for my channel.

I also updated the associated article.

YouTube : 6 Months and 1000 Subscribers!

That’s right, it’s been a touch over 6 months and my YouTube channel has just hit the 1000 subscriber mark. :)

This YouTube experience has been quite odd. My plan was to try and upload a video every weekday for the first 2 months, and I came pretty close to hitting that target. Once I had got a bit of content on the channel, I was inevitably going to kick back a little. After all, there is the website, the blog, life and that annoyance they call work to consider. I think a realistic target is to aim for is 1-2 videos a week.

There will inevitably be periods (like this last 2 weeks) where I don’t hit that, but just like writing, I’m not going to beat myself up about it. It’s the normal ebb and flow of things.

So far the technical videos have almost all been based on command line examples, which is similar to my approach when doing technical presentations. That’s suited me while I’ve been finding my feet, but over time there will be a number of different formats. I’m probably going to avoid having my image in the videos. I don’t like being in front of the camera that much, as I have to suck my gut in for extended periods of time. :) I liked doing the car videos, as I was less self conscious about the camera while I was concentrating on the driving, but the sound quality was really bad, so I’m not sure if I’ll do more of those. We shall see.

The channel content will become more eclectic over time, because the DBA job is quite eclectic. There’s no point trying to bullshit about being a specialist, because I’m not one.

I would quite like to try my hand at some totally non-technical stuff, like a vlog maybe, but if I do that, it will probably end up on another channel, so it doesn’t dilute this channel too much. We’ll see what happens.

Anyway, to everyone who has subscribed so far, thank you. Thanks to all the folks that have done cameos for me so far. I’ve got a whole bunch more coming. If you’ve not already seen my channel, give it a try and see what you think.

Here’s to the next 1000 subscribers!

Cheers

Enterprise Manager Cloud Control 13c : Navigation and “Look and Feel”

o-enterprisemgr-13c-clr-2769481I’ve continued to play around with Cloud Control 13c and I’m generally getting a nice vibe from it.

One of the things I really hated about Grid Control 10g and 11g was the navigation. It felt like you had to click on 50 links to get to the thing you wanted. When Cloud Control 12c came along and had a main menu it was a massive improvement. Even so, it was still a little annoying as the menu was split, with some bits on the left and some bits on the top-right.

em12c-menu

In Cloud Control 13c, these menus have been brought together into the top-right of the screen.

em13c-menu1

If the screen size is smaller, the buttons collapse to show just the icons, which saves space.

em13c-menu2

It probably sounds really trivial, but having both menus together is a really nice touch. I can’t count the number of times I’ve been fumbling around, unable to find something, only to remember it is in that blasted menu at the top-right. Now there is no excuse. :)

The job scheduler navigation is also a lot nicer. In Cloud Control 12c we had a bunch of drop-downs and a “Go” button.

em12c-jobs

In Cloud Control 13c there are tiles along the top to alter the context of the output and the tree on the left allows you to quickly flip between criteria.

em13c-jobs

It is so much quicker to get the information you want this way.

So as far as I’m concerned, Cloud Control 13c is getting a big thumbs-up from a navigation perspective!

A couple of people have asked my impression about the new look and feel. If we ignore the navigation, most of the pages are quite similar to what we had before, so there is no need to panic. Overall it has a sparser, cleaner look, which is more in keeping with the way the web is these days, so I think that’s a good thing. Anyone who has used Oracle Cloud will find the look very familiar. :)

I guess the biggest bonus of the new look and feel is it is more responsive. On some of the old pages you had a lot of sideways scrolling to do if you have a small browser window. The new look and feel deals a lot better with that. It’s not perfect, but it is better. So I’m giving the new look and feel a big thumbs-up too!

Being the bitter old man that I am, I reserve the right to change my mind and hate it all in the future. :)

Cheers

Caveat: I use a very small subset of the functionality available from Cloud Control, so my opinion is going to be based on the bits I use a lot. It might be that other areas have been adversely affected by the new navigation or look and feel, but the bits I care about are looking good.

MobaXterm 8.5

MobaXterm 8.5 was released at then end of last year. The download and changelog can be found here.

If you use a Windows desktop and you ever need to SSH a server or use X emulation, you need this bit of software in your life. There is a free version, or you can subscribe to support the development.

Give it a go. You won’t regret it.

Oracle Linux : UEK4 Released

linux-tuxI wrote a post a couple of months ago called
Which version of Oracle Linux should I pick for Oracle server product installations? One of the points I raised was the use of UEK allows you to have all the latest kernel goodies, regardless of being on an older release, like OL6.

I saw a post today about the release of UEK4, so now you have access to all the improvements in the 4.1 mainline Linux kernel, whether you are on are running OL6 or OL7. That just goes to prove the point really.

If you are running RHEL, you might be feeling pressure to move from RHEL6 to RHEL7 to get a bunch of the kernel enhancements that came with it. If you are running OL6, just switch to UEK4 and your kernel is ahead of the RHEL7 kernel. No stress and no having to deal with systemd and firewalld. :)

Enterprise Manager Cloud Control 13c Upgrade

em-12cA couple of weeks ago I posted about doing a fresh installation of Enterprise Manager Cloud Control 13c (article, blog post). I’ve finally got around to doing an upgrade test from EM CC 12cR5 to 13cR1. You can see the result of that here.

upgrade-meme

Gokhan Atil did a post about this upgrade pretty much as soon as it was released, so I’m a little late to the party compared to him. :)

As you’ll see from the article, the upgrade process was similar to the patches that came before it. There are of course some extra prerequisites which you can read about in either my post, Gokhan’s or the docs…

Even though the upgrade tests were fine, after discussion with our system administrators, we are probably going to go for a clean installation and migrate the monitored hosts one at a time.

Why the slash and burn approach? I’ve made some mistakes with our installations in the past and they persist with every subsequent upgrade. It would be nice to take a step back and fix stuff. We are doing a similar thing with our WebLogic installations. I was learning new stuff all the time while I was installing our WebLogic 11g infrastructure. Rather than upgrading to WebLogic 12cR2, we are going to build a new infrastructure, migrate to it and throw the old one away.

This is relatively easy for us for a few reasons.

  1. We use virtualization for everything. We will provision the new VMs, set everything up. Start migrating stuff. When the migration is complete we will throw away the old VMs. No major hardware overhead.
  2. We are a pretty small operation. If we had a massive amount of infrastructure, a slash and burn approach would be very time consuming and as such, very costly.
  3. I am really anal about some things and I am willing to go the extra mile to get things right. I did the best I could at the time, but I’m happy to admit I made mistakes and I want to sort them out. This is not because I’m a company boy. It’s because those mistakes eat away at me and I want them eradicated so they will only haunt me in my memories, not in my day to day life.

If we had been going for the upgrade approach, I probably would have done it in the next couple of weeks. With clean slate approach, we’ll probably take a few more weeks to get ready for it. No point rushing in and making more mistakes. I would rather let the idea brew for a while before we start. :)
