Friday Tips #14

Our tip this week will help you experiment with the settings for the Sun Ray Operating Software (SROS).

Question:
I want to setup SROS (Sun Ray Operating Software) and play with the server based .parms files and the DTU GUI. What are the quick steps to get that done?

Answer by John Renko, Consulting Developer, Oracle Desktop Virtualization:
Good news, SROS isn't too different from the "old" ways of managing the operating software on Sun Ray DTUs.

1) Download the latest SROS package from My Oracle Support (support.oracle.com)

2) Unpack the package and install it on your Sun Ray server:

pkgadd -d . SUNWutdfw

3) Prepare a sample "srconfig" file with some common settings:

bash-3.2# cat /srconfig
compress=1
fastload=1
fulldup=1
lossless=0
poweroff=120
select=random
servers=myhouse.domain.com,myhouse2.domain.com

4) Deploy the SROS, with GUI enabled, so you can play with the DTU settings:

/opt/SUNWut/sbin/utfwadm -AaV -i /srconfig -G force

You should now see SROS images in /tftpboot along with .parms files, merged with your /srconfig settings and a SunRay.enableGUI object.

Friday Tips #13

In honor of the new version of the Oracle Virtual Desktop Client yesterday, we thought we'd do a tip for the power users of our client software:

Question:
How can you run multiple Oracle Virtual Desktop Client sessions simultaneously?

Answer by John Renko, Consulting Developer, Oracle Desktop Virtualization:
You simply need to run each Oracle Virtual Desktop Client (OVDC) session with a --profile option.

For example, one could launch two sessions by doing:  

ovdc.exe --profile ovdc1
ovdc.exe --profile ovdc2

Each session will retain its settings, logs and contain its own client ID, which can useful when managing Sun Ray session assignment to a Kiosk or regular session, amongst other things:

ovdc.exe --profile ovdc1 -i

[ A popup window appears with the client ID ]

On Mac OS X platforms, the path to the OVDC binary would be:

 /Applications/Oracle Virtual Desktop Client.app/Contents/MacOS/ovdc

Some example scenarios of where this is useful:

  1. You need to connect to multiple environments concurrently.
  2. You need to make concurrent connections to a single environment using multiple user IDs.
  3. You want to run a large load test and have a server that can run 200 simultaneous OVDC sessions, like this:

Thanks John, that could come in handy for lots of different testing scenarios.

That's it for this week. If you have anything you want to ask us, just post on Twitter with #AskOracleVirtualization and we'll try to get your question answered. See you next week!

Hear us talk about BYOD!

Recently, I had the pleasure of spending some time on the phone with John Renko, consulting developer in the desktop virtualization group here at Oracle. You might know him from his fantastic answers to many of our Friday Tips questions.

While BYOD has become a pretty common idea over the last couple of years, John has been conducting his job using BYOD principles for many years. And given his job developing desktop virtualization technologies, he's an expert in the space. You can hear John and I talk about how BYOD works, what sorts of things are ideal for it, some things that aren't a perfect fit, and more in this podcast:

My thanks for John for taking the time to speak with me!

Friday tips #2

Welcome to our second Friday tips blog! You can ask us questions using the hash tag #AskOracleVirtualization on Twitter and we'll do our best to answer them.

Today we've got a VDI related question on linked clones:

Question: I want to use linked clones with Oracle Virtual Desktop Infrastructure. What are my options?

Answer by John Renko, Consulting Developer, Oracle:

First, linked clones are available with the Oracle VirtualBox hypervisor only.

Second, your choice of storage will affect the rest of your architecture.

If you are using a SAN presenting ISCSI LUNS, you can have linked clones with a Oracle Enterprise Linux based hypervisor running VirtualBox. OEL will use OCFS2 to allow VirtualBox to create the linked clones. Because of the OCFS2 requirement, a Solaris based VirtualBox hypervisor will not be able to support linked clones on remote ISCSI storage.

If you using the local storage option on your hypervisors, you will have linked clones with Solaris or Linux based hypervisors running VirtualBox.

In all cases, Oracle Virtual Desktop Infrastructure makes the right selection for creating clones - sparse or linked - behind the scenes. Plan your architecture accordingly if you want to ensure you have the higher performing linked clones.
