Friday Tips #46, Pre Oracle OpenWorld Edition

Happy Friday, everyone!

Since we're just a couple of days away from the start of Oracle OpenWorld, I thought I'd use the tip this week to give you some picks on virtualization material that you just shouldn't miss at the show. We've done several blogs about the content at this year's show, but here are a few items to take into account as you're planning your week:

General Session

We covered this one yesterday, but it's worth highlighting again. This is the go to session for definitive virtualization information right from Oracle execs. You can even get your virtualization questions answered by the executive team. Hope to see you at this one!

Customer Sessions

We also covered a few of these earlier this week, but here is a more complete list:


Hands On Labs

Product Demonstrations

In the DEMOgrounds in Moscone South you'll find demo pods for Oracle VM Server for x86, Oracle VM Server for SPARC, Oracle VM Templates, Oracle desktop virtualization, and more!

Now, this list of highlights isn't meant to imply that you shouldn't try to take in all the fantastic content at the show, it's just a list of things you for sure should not miss! You can see a complete list of what's happening in virtualization with our Focus On Virtualizaiton document.

We hope you have an exciting, educational, and fun time at Oracle OpenWorld 2013!

Happy Friday!

Our tip this week is on Oracle Secure Global Desktop, which provides secure remote access to Oracle Applications and other enterprise software. One of the really great things about Secure Global Desktop is that once the administrator has setup an application the first time, providing access to that application to any number of users takes literally seconds.

Check out this great step by step tutorial for publishing an application to an entire group of users in the enterprise directory by the Fat Bloke:

Controlled Application Deployment with Secure Global Desktop


Speaking of Secure Global Desktop, if you're coming to Oracle OpenWorld, don't miss a fantastic session we're doing on the topic of secure application access, featuring Airbus and NHS Lothian. Both of these large organizations use Secure Global Desktop as an access layer for a variety of applications from many different types of devices. It will be a fascinating session and if you're at all interested in remote access, security, application virtualization, or anything similar, you won't want to miss it.

Happy Friday, folks! If you've been keeping up with this blog, you've been seeing a lot of posts on Oracle VM Templates. With the recent updates to the Oracle VM Templates for Oracle Database, it's been a pretty exciting time! But I thought I'd take this opportunity to point out that in addition to these, there are many more templates you can choose from. There are templates for Oracle E-Business Suite, Oracle Siebel CRM, Oracle PeopleSoft, JD Edwards, Oracle Identity Management, Oracle Linux, Oracle Solaris, Oracle Secure Global Desktop, and much more. It's the fastest way to get up and running with Oracle software.

This page is an index of the many Oracle VM Templates you can choose from:

Friday Tips #42

Happy Friday! With this week's release of Oracle VM Server for SPARC 3.1, it's a perfect time to offer a tip on how to upgrade your systems to the latest version. Oracle's Jeff Savit had this to say about the upgrade process:

"Updating to Oracle Solaris 11.1 to include Oracle VM Server for SPARC 3.1 takes little effort - it only requires a few commands and a few minutes per server. This can be done with the CLI or with Oracle VM Manager."

For the complete step by step guide, check out Jeff's blog detailing the procedure here: 

Upgrading to Oracle VM Server for SPARC 3.1 using Solaris 11.1

See you next week!

Friday Tips #41

Happy Friday, everyone!

As you might have heard, we introduced Oracle's latest engineered system, the Oracle Virtual Compute Appliance this week. If you've been reading the blog over the last few days, you've seen quite a bit of information about it. If you haven't seen it, I highly recommend Adam Hawley's post where he discusses it from the product management viewpoint.

Even with all this information, there is still a lot more to know. That's why I wanted to point you to the Oracle Virtual Compute Appliance Frequently Asked Questions document, which contains even more info. For instance:

  • What is Oracle Virtual Compute Appliance?
  • What are the components of the Oracle Virtual Compute Appliance (hint: it includes Oracle VM!)?
  • Can Oracle VM templates be used with Oracle Virtual Compute Appliance (short answer: Yes!)?
  • Which guest operating systems are supported?
  • What are the hardware specifications of the nodes?
  • And much more

Head on over to the Oracle Virtual Compute Appliance FAQ document to learn the answers to these and many more questions.

See you next week!

Friday Tips #39

Happy Friday! Our tip this week is on a little quirk of using Oracle VM 3 with templates developed in Oracle VM 2.

Question:
Why do I see new Oracle VM 3 networks named xenbr0 and xenbr1 after importing an Oracle VM Template?

Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management:
Some legacy Oracle VM Templates as well as some newer templates are designed to come pre-configured with network interfaces for Oracle VM 2 environments. Oracle VM 3 doesn’t really know what to do with the pre-configured network devices during the import process of an Oracle VM Template, so the product errors on the side of caution by creating place holders for networks. 

This means Oracle VM 3 automatically creates superfluous or false networks using the name of xenbr0, xenbr1, etc. when you import an Oracle VM Template that uses the Oracle VM 2 naming convention for bridges. So you are left with new networks named xenbr0 or xenbr1 that are useless since they are not associated with any servers, network ports or bonds. This can be quite confusing.

The problem is very easy to fix. Simply edit the newly imported Oracle VM Template, replace the networks named xenbr0 and xenbr1 with your real networks, then switch to the Network tab, highlight the networks named xenbr0 and xenbr1 and then delete them. 

Here is a step-by-step example... 

The screen shot below shows Oracle VM networks before a template is imported:

The next screen shot shows the superfluous networks after the new template has been imported:

The networks named xenbr0 and xenbr1 can safely be removed after they are no longer being used by the newly imported Oracle VM Template. Simply switch to the Repositories tab, find and edit the newly imported template as show in the screenshot below:

Now move xenbr0 and xenbr1 to the left hand box while moving the correct network or networks to the right hand box as shown in the screen shot below:

Finally, switch to the Networking tab, highlight and then delete the networks named xenbr0 and xenbr1 as shown in the screenshot below: 

...and now your Oracle VM networks should look just like they did before importing the template :-)


Thanks Greg!

We'll see you all next week with another tip!

Friday Tips #38

Happy Friday! This week's tip is on Oracle VM Server for SPARC, and it's just a quick pointer to a really great paper. 

A common scenario for Oracle Database users is to run the database on Oracle Solaris and use Oracle VM Server for SPARC as the virtualization technology. Of course, one of the great benefits of virtualization is portability, but how do you move an instance of the database to take a physical server offline (to add more memory, for example)? The Oracle white paper Increasing Application Availability by Using the Oracle VM Server for SPARC Live Migration Feature: An Oracle Database Example will tell you the hows and whys of this important process.

See you all next week!

Friday Tips #37

Happy Friday! This week we're talking about tips and tricks for fullscreen mode in Oracle VM VirtualBox.

I use typically Oracle VM VirtualBox on the Mac and I find it very convenient to set my virtual machines to run in full screen mode in a separate Space. I'm using Mountain Lion, but this should be similar for Mavericks (I think, I haven't used it yet!).

To go full screen, first, launch your virtual machine. You can then use the host key (command on the Mac) and F to go full screen. You can also switch to full screen in the menu bar with View->Switch to Fullscreen. There's also a useful option there that will set the resolution of the guest OS to match your monitor, and that is View->Auto-resize Guest Display.

In the Mac on Mountain Lion (and perhaps on Lion, I don't have it around to confirm), this full screen VM will have its own Space. That means you can do the three finger quick swipe left or right to switch between your local Mac OS spaces and your full screen virtual machine. It's extremely cool. Another thing I do to make moving between the virtual machine and the Mac OS desktop even easier is to go into Mission Control (three finger swipe up on a trackpad, or open the app itself) and drag the Space with the VM in it all the way to one side or the other of your Spaces - I prefer the right side. Then in the Mission Control System Preference, turn off "Automatically rearrange spaces based on most recent use." What this does is ensure that you can quickly three finger swipe all the way left or all the way right to get either a Mac OS desktop or your fullscreen VM.

One other quick tip. If you don't find yourself needing the items in the mini-toolbar, you can hide it by clicking on the VM in Oracle VM VirtualBox manager, and then clicking on "Settings" in the toolbar. In the General tab of that dialog box, click Advanced and then uncheck Mini ToolBar: Show In Fullscreen/Seamless. The only thing I use the Mini Toolbar for on a regular basis is suspending the VM, which you can do just as easily by press the host key (again, command on the Mac) and Q. You'll get the same dialog that you get when pressing X on the mini toolbar.


I hope that makes working in fullscreen mode with Oracle VM VirtualBox a little easier for you!

Friday Tips #34

Happy Friday! I wanted to take the opportunity this week to not give out a tip per se, but to point you to a really fantastic white paper that you might have missed. It's called What It Takes to Deploy and Manage a Private Cloud with Oracle VM. The paper is filled with useful information and it's written in a really entertaining style, tackling the IT challenges of a friendly systems administrator named Dave. It gives a great overview of application-driven virtualization and covers Oracle VM, Oracle VM Templates, Oracle VM Storage Connect, and Oracle Enterprise Manager.

Friday Tips #33

Happy Friday, everyone!

Our tip this week is from an excellent white paper written by our own Greg King titled Oracle VM 3: Building a Demo Environment using Oracle VM VirtualBox. In it, Greg gives you everything you need to know to set up Oracle VM Server inside of Oracle VM VirtualBox for testing and demoing. The section we're highlighting below is on how to configure the network interfaces of your virtual machines:

VirtualBox comes with a few different types of network interfaces that can be used to allow communication between the VM guests and the host operating system, including network interfaces that will allow the VM guests to communicate with local and wide area networks accessed from your laptop or personal computer. However, for the purpose of the demonstration environment we will limit the network communication to include access just between your desktop and the virtual machines being managed by VirtualBox.

The install process for Oracle VM VirtualBox creates a single host-only network device on your laptop or personal computer. Using the host-only network device will allow you to open a browser on your desktop to access the Oracle VM Manager running within the VirtualBox VM guest. The device will only allow network traffic between the VM guests and your host operating system, but nothing outside the confines of your laptop or personal computer.

We will need to add a second host-only network since the Oracle VM Server appliance has both eth0 and eth1 configured. You can choose to use eth1 on the Oracle VM Servers or not use them – the choice is yours. But, at least the host side network device will exist if you decide to use it.

Greg goes on to describe in detail how to setup the network interfaces, so you can head on over to the paper and get even more info.

See you next week!

Friday Tips #32

Happy Friday! Our tip this week is about Oracle Secure Global Desktop and directory services.

Question:
What versions of Active Directory and LDAP does Oracle Secure Global Desktop support? 

Answer from the Deployment Considerations for Oracle Secure Global Desktop white paper:
Active Directory authentication and LDAP authentication are supported on the following versions of Active Directory:

  • Windows Server 2003
  • Windows Server 2003 R2
  • Windows Server 2008
  • Windows Server 2008 R2
  • Supported LDAP Directories

Oracle Secure Global Desktop supports version 3 of the standard LDAP protocol. You can use LDAP authentication with any LDAP version 3-compliant directory server. However, Oracle Secure Global Desktop only supports the following directory servers:

  • Oracle Directory Server Enterprise Edition version 11gR1
  • Microsoft Active Directory on Windows Server 2003, 2003 R2, 2008, and 2008 R2
  • Oracle Internet Directory 11gR1 (all 11.1.1.x.0 releases)

Other directory servers might work, but are not supported.

For more detail, have a read through the User Authentication section of the documentation

See you next week!
