Friday Tips #31

Happy Friday, everyone!

Our tip this week answers a question that comes up often.

Question:
When deploying Oracle Virtual Desktop Infrastructure, how many users can a single server support?

Answer from information in the Oracle's Single Server Solution for VDI white paper:
As part of a single server solution (meaning, the hypervisor, storage, and management pieces are all on one machine and no other systems are necessary), Oracle tested two different configurations and came up with a guideline for how many users these systems can support. Please remember, this is just a guideline and not a guarantee or assurance of performance.

Configuration #1 (this is called the "base configuration" in the paper):

  • Sun Server X3-2L based on Intel Xeon E5 2660 processors
  • 128 GB 1600 MHz RAM (expandable to 512 GB)
  • 16 x 600G SAS-2 10K RPM disks 
  • Based on a customized “Large” configuration on the Oracle store 
  • Targeted at 90-95 users per system

Configuration #2 (this is called the "performance configuration" in the paper):

  • Sun Server X3-2L based on Intel Xeon E5 2690 processors 
  • 256 GB 1600 MHz RAM (expandable to 512 GB) 
  • 26 x 600G SAS-2 10K RPM disks 
  • Offered as “Large” configuration on the Oracle store 
  • Targeted at 180-190 users per system

If you'd like to get some more detail on this, head on over to the Oracle's Single Server Solution for VDI white paper for a lot more info.

We'll see you next week!

Friday Tips #27

Happy Friday! If you're been following this blog, you saw last week's tip on accessing applications and desktops with Oracle Secure Global Desktop over a cellular connection using just HTML5 on an iPad. This week's question concerns HTML5 in desktop browsers:

Question:
Does Oracle have plans to support HTML5 when using desktop browsers for Oracle Secure Global Desktop?

Answer by Mohan Prabhala, Product Management Director, Oracle:
We can't discuss possible future directions. But if you want to get a feel for what it would be like to use Oracle Secure Global Desktop with HTML5 on a desktop browser (specifically the Chrome browser on a Mac, a Windows 7 PC, or a Linux based PC), you can try the following workaround.

Please note: that the workaround below is provided AS-IS, is NOT a supported configuration, and, at Oracle's sole discretion, may not be supported within Oracle Secure Global Desktop. Accordingly, this workaround must NOT be used for production deployments.

1) On the SGD server:

vi /opt/tarantella/webserver/tomcat/7.0.37_axis1.4/webapps/sgd/WEB-INF/web.xml

2) Inside the web.xml file you should see a parameter

<context-param>
      <param-name>clienttype</param-name>
      <param-value>AUTO</param-value>
</context-param>

Change the param-value to “H5C”

<context-param>
      <param-name>clienttype</param-name>
      <param-value>H5C</param-value>
</context-param>

3) Restart the SGD server:

/opt/tarantella/bin/tarantella restart

That’s really it. Let us know what you think, either via your Oracle sales rep or via this blog or our Twitter and Facebook social media channels.


Thank Mohan!

We'll see you next time with another tip. Have a great week!

Friday Tips #26

Happy Friday! With the exciting release of Oracle Secure Global Desktop 5.0 this week, we though we'd do something a little different with our Friday tip.

Since access via iPad with HTML5 is a big part of this release, a question that has come up a few times is what performance is like over cellular connections. So, we recorded some video of an iPad using an iPhone 5 on LTE as a mobile hotspot, connecting back to an Oracle Secure Global Desktop server. You can see the real world cellular performance in the video below:

See you next week!

Happy Friday, everyone! We had a great week at Collaborate 13, thank you to everyone who stopped by the booth. We also blogged about "Oracle VM and Oracle Linux pre-validated, pre-tested with FlexPod", released version 4.2.12 of Oracle VM VirtualBox and version 4.63 of Oracle Secure Global Desktop. Lots of great stuff going on!

Speaking of Oracle Secure Global Desktop, our Friday Tip this week is on that very product. In this video tip, Mohan Prabhala covers how to disable or enable copy functionality in applications to increase security:

Friday Tips #22

Happy Friday, everyone! Today's tip on the really cool Location Awareness feature of Oracle Virtual Desktop Infrastructure:

Question:
How can I tell if location awareness is working?

Answer from "Using Location Awareness with Oracle Virtual Desktop Infrastructure":
Use the command prompt to check the clientname environment variable. Simply login to the virtual desktop from the first Sun Ray Client, start a Windows command prompt, and type:

echo %clientname%

Close the command prompt window, login to the same virtual desktop from a second device and repeat the process. If everything is functioning properly, the clientname environment variable will change.

We'll see you next week with another tip!

Friday Tips #21

We hope you're having a great Friday! Here is our Friday tip:

Question:
Can I run VDI with just a single server?

Answer by Chris Kawalek, Senior Principal Product Director, Oracle Desktop Virtualization Marketing:
Absolutely! Oracle Virtual Desktop Infrastructure allows you to deploy on a single server for everything you need for a VDI deployment: brokering, running VMs, and storage. Properly outfitted, this single server should be able to support up to 180-190 users. You can read exactly how to do this, what kind of server it requires and more in this new white paper:

Oracle's Single Server Solution for VDI

Another great thing about this solution is that it easily scales. If you add a second server, you can use its own internal storage for HA. And you can add external storage and more servers if you want to scale even higher. And at no point do you have to install a different product or do a massive reconfiguration to grow from a small pilot or departmental deployment to an enterprise one.

We'll see you all next week!

Friday Tips #20

We hope you've had a good week and happy Friday! It's time for our 20th Friday tip. This one is about installing Oracle VM VirtualBox for use with Oracle Virtual Desktop Infrastructure:

Question:
How do I install VirtualBox to use it with Oracle Virtual Dekstop Infrastructure?

Answer by the Oracle documentation team:
Unzip the VirtualBox software archive, change working directory to the extracted directory, and install the software with the vb-install script, as follows:

# unzip vbox_4.2.zip
# cd vbox_4.2
# ./vb-install

VirtualBox consists of two components, a Base Pack and an Extension Pack. The VirtualBox software archive contains only the Extension Pack. However, the vb-install script downloads the VirtualBox Base Pack, and then installs both the Base Pack and the Extension Pack. If the Base Pack download fails, you must manually download it from here. Make sure you download the release that is bundled and supported with the release of Oracle VDI. Copy the Base Pack to the same directory as the vb-install script, and then run the script again.

The vb-install script prompts you for a user name, a password, and a port number to use for SSL connections.

The user name and password is for the user that runs VirtualBox on the host. On Oracle Linux platforms and Oracle Solaris platforms where root is a user, the root user is used by default. It is best to use the root user on these platforms. On Oracle Solaris platforms where root is a role, you must provide the credentials for a different user.

If the VirtualBox user is root, the SSL port is port 443 by default. Otherwise, port 18083 is used by default. If another process is using the default port, the vb-install script suggests another available port. If you plan to install Oracle Secure Global Desktop software on this host as well and port 443 is selected, choose a different port.

Make a note of the user name and port, you need these later.

After a few minutes, the installation is complete.


The answer to this question is from the Oracle Virtual Desktop Infrastructure Getting Started Guide for Release 3.5. There's lot of great information in there, so have a read through it if you want to get a good sense for how to plan your install.

We'll see you next week!

Friday Tips #17

Happy Friday, everyone! We're busy getting ready for HIMSS13 in New Orleans (we'll be posting during the show next week, so please stay tuned for that), but that won't stop us from doing our Friday tip. This week's question focuses on Oracle Secure Global Desktop:

Question:
How do I setup an LDAP server using the command line option within Oracle Secure Global Desktop?

Answer by Mohan Prabhala, Product Management Director, Oracle:
The ‘–login-ldap-url’ command line option was removed since Oracle Secure Global Desktop version 4.6. So using the ‘–login-ldap-url’ option when running the ‘tarantella config edit’ command will not work. You must use a service object which is a group of directory services configuration settings used for SGD authentication mechanisms. So the commands below should be the way to make this work: 

tarantella config edit --login-thirdparty 1 
tarantella config edit --login-ldap-thirdparty-profile 1 
tarantella config edit --login-ldap 1 
tarantella service new --name generated --type ldap --url "ldap://<server hostname>" 

It is important to note that authentication mechanisms such as LDAP are used by Oracle Secure Global Desktop to login into the webtop. By default, Oracle Secure Global Desktop does not query LDAP during the launch of an application (once in the webtop). It is possible to pass through LDAP credentials to authenticate applications at launch time using the Authentication Configuration Tool (authconfig).
