TOTD #68: Installing Zones in Open Solaris 2008/11 on Virtual Box
The TOTD
#64 describes how to install Open Solaris 2008/11
using Virtual Box.
This Tip Of The Day (TOTD) is going
to explain how to install non-global zones
(aka Solaris Containers) on this Open Solaris image. Containers provide
an operating-system level virtualization technology.
Thanks for the
extensive discussion at zones-discuss
forums, Bill
Walker for lots of off-line support, and last but not the
least Marcelo
Arbore's nice blog showing how to install GlassFish
in an Open Solaris zone.
This blog is going to focus on installing couple of non-global
containers/zones in the Virtual Box image with all gory details. A
later blog will show how to leverage these zones to demonstrate GlassFish
High Availability.
Lets get started!
To begin with, there is one global zone always installed as shown below
(user
inputs highligted in bold):
| arun@opensolaris:~# zoneadm
list -vi ID NAME STATUS PATH BRAND IP 0 global running / native shared |
Lets install the zone. The IP address is specified in 192.168.0.XXX range ...
| arun@opensolaris:~# zonecfg
-z zone1 zone1: No such zone configured Use 'create' to begin configuring a new zone. zonecfg:zone1> create zonecfg:zone1> set zonepath=/export/home/zone1 zonecfg:zone1> set autoboot=true zonecfg:zone1> add net zonecfg:zone1:net> set address=192.168.0.99/24 zonecfg:zone1:net> set physical=e1000g0 zonecfg:zone1:net> end zonecfg:zone1> commit zonecfg:zone1> exit arun@opensolaris:~# zoneadm -z zone1 install A ZFS file system has been created for this zone.

This comment indicates successful creation of the zone.
Login to "zone1" as:
| zone1 console login: root Password: Feb 8 16:12:10 zone1 login: ROOT LOGIN /dev/console Sun Microsystems Inc. SunOS 5.11 snv_101b November 2008 |
Check the network configuration ...
| root@zone1:~# ifconfig
-a lo0:1: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 e1000g0:1: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 2 inet 192.168.0.99 netmask ffffff00 broadcast 192.168.0.255 root@zone1:~# |
After "zone1" is completely installed, then it can be viewed as:
| arun@opensolaris:~$ zoneadm list -vi ID NAME STATUS PATH BRAND IP 0 global running / native shared 1 zone1 running /export/home/zone1 ipkg shared |
And then install "zone2" using the steps described above and check it's network configuration as:
| root@zone2:~# ifconfig -a lo0:2: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 e1000g0:2: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 2 inet 192.168.0.98 netmask ffffff00 broadcast 192.168.0.255 root@zone2:~# |
And it's shown in the list of zones as:
| arun@opensolaris:~# zoneadm list -vi ID NAME STATUS PATH BRAND IP 0 global running / native shared 1 zone1 running /export/home/zone1 ipkg shared 2 zone2 running /export/home/zone2 ipkg shared |
OK, so we installed 2 non-global zones in an Open Solaris image running as guest in Virtual Box.
Typing "~." takes you back to the global zone.

TOTD #64: OpenSolaris 2008/11 using Virtual Box
Here is a blog entry that was sitting in my Drafts folder for a long
time
(just because I didn't realize :). Anyway, it shows how to install Open Solaris 2008/11
on Virtual Box.
The original install was done using Virtual Box 2.0.6. I installed
Virtual Box 2.1 this morning and the image was easily recognized by the
updated Virtual Box.
Here are the basic steps.
Create a new VM ...
As part of the previous step, create a new Virtual Disk mapping to the
downloaded Open Solaris image ...
The generated VM settings are shown as below:
Click on "Start" and configure for the first run as:
Boot the Virtual Macine from the LiveCD shows the following GRUB:
Take the default for Language and Keyboard and then the following
screen is shown after the boot:
Click on "Install OpenSolaris" ...
Clicking on "Install" starts the installation ...
And finally the install is completed.
Click on "Reboot", select "Boot from Hard Disk" and press Enter ...
And then select if "full boot" or "text boot" is required as shown:
And the welcome screen is shown as:
Now you can develop your Rails
applications using the NetBeans
IDE and deploy them on GlassFish
and MySQL easily as
explained here.
There are multiple updates to the stack described earlier - JRuby 1.1.6,
Rails
2.2, MySQL
Alpha 6.0.x, GlassFish
v3 Prelude, and Virtual Box
2.1.
So go ahead and develop, deploy, and debug your Rails applications as
described in screencast
#26. You can even manage your Rails applications using JMX as
described in TOTD #61,
#62,
and #63.
Hwo do you follow the latest on each technology:
- Open Solaris at The Observatory and twitter.com/opensolaris.
- Virtual Box at Virtual Box Buzz.
- GlassFish at The Aquarium and twitter.com/glassfish.
- Rails at Riding Rails and twitter.com/rails.
- MySQL at Planet MySQL.
- JRuby at #jruby (archived).
- NetBeans at NetBeans Planet and twitter.com/netbeans.

CIO published an article
highlighting 5 cheap (or free) software that can be afforded during
financial crisis. Their recommendations are:
- Open Office ($0) instead of Microsoft Office ($110 for basic version)
- Mozilla Thunderbird ($0) instead of Microsoft Outlook (lots of security issues)
- GnuCash ($0) instead of Quicken ($30 for starter edition)
- Alfresco ($0) instead of Sharepoint ($5K for five licenses)
- Linux instead of Windows (non-zero cost, always virus-prone ;)
Here are some more recommendations ...
- GlassFish instead of Oracle Weblogic or IBM Websphere
- MySQL instead of Oracle Enterprise or IBM DB2
- OpenSolaris instead of Windows
- NetBeans instead of IntelliJ
- VirtualBox instead of VM Ware or any other virtualization software
- and many more here
Now some actual price comparisons using GlassFish and MySQL Unlimited ...
That's $3 million savings over a period of 3 years!!!
And if the number of sockets/cores go up, that's just additional money you are wasting during this financial crisis. With GlassFish Enterprise Unlimited starting at $25,000 - no counting cores, sockets, support incidents, servers or auditing - you can deploy unlimited GlassFish instances for the same price charged for one WebLogic Enterprise Edition. GlassFish for Business explains the value of buying subscription for your deployments.
Here is another comparison for Total Cost of Ownership for MySQL compared with other databases:
Can your apps scale more than Google, Facebook, Yahoo or Wikipedia ? All these sites are powered by MySQL. Do they need to be more reliable than telco vendors such as Vodafone ? Again powered by MySQL.
In an open source world, why have a "30-day" evaluation period ?
In the times of financial crisis, why spend extra money when there are other better options available with HUGE savings ?
Open Source software is indeed a great way to cut costs. And Sun Microsystems offer a wide varitey of open source offerings (GlassFish, MySQL, OpenSolaris, VirutalBox, Linux, NetBeans and many others) that can help you during this financial crisis!

JRuby-on-Rails and MySQL on GlassFish on OpenSolaris in Virtual Box VM
My primary development machine is Mac OS Leopard
on Intel Core 2 Duo (read osxtips).
But the beauty of virtualization
is that I can run multiple Operating Systems on a single powerful
machine. And what better virtualization product than Virtual Box.
And Open
Solaris has crossed leaps and boundaries making installation
and getting started extremely simple :)
So here is an application stack that I tried:
 |
Rails 2.1
+ My
SQL 5.0.51a JRuby 1.1.2 GlassFish v3 TP2 OpenSolaris 2008.05 Virtual Box 1.6.2 Mac OSX Leopard Intel 2.4 G Hz Core 2 Duo |
You can easily deploy your Rails applications using MySQL database on GlassFish installed on OpenSolaris in a Virtual Box VM on Mac OS Leopard running on an Intel 2 Duo processor machine. Overall a happy experience :)
The complete instructions to install OpenSolaris using Virtual Box are very useful.
Here are basic steps ...
Create a new VM (settings given in the instructions):
Once all the options are chosen, the generated VM settings are shown as below:
Booting the Virtual Machine from the Live CD shows the following GRUB:
Pick the default options (GRUB, Keyboard & Language) and then the following default screen is shown:
Read and Close the license screen. And then click on the "Install Open Solaris" icon to continue the installation process. This step is important otherwise you'll keep booting from LiveCD every time (I messed up on this few times ;).
After choosing the Region, Location & Timezone and taking other defaults, the summarized installation options are shown:
And finally the installation is complete:
After the installation is complete, shutdown the VM by either selecting "System, Shut Down..." or click on the X on the VM window and selecting "Power off the machine". Change the boot sequence order to bring "Hard Disk" at the top by clicking on "Settings", "Advanced" tab and changing the order as shown below.
And finally, you can easily deploy a Rails 2.1 application on this newly configured machine as explained in Rails 2.1 on GlassFish. TOTD #35 explains how Rails Database connection need to be configured on Solaris.
The final output of the application looks like:
Here are some pointers for you to get started:
- Virtual Box 1.6.2
- OpenSolaris 2008.05
- GlassFish v3 TP2
- JRuby 1.1.2
- Rails powered by the GlassFish Application Server
Stay in touch with us by posting your questions/comments/concerns to GlassFish Web Tier Forum or webtier@glassfish.

TOTD #35: Rails Database Connection on Solaris
Are you deploying your JRuby-on-Rails applications
on Solaris
(or any variety of Unix) and not able to connect to the database ?
I experienced it last week so thought of sharing the tip here. Luckily
it's really simple.
Here is the default generated "config/database.yml"
| development: adapter: mysql encoding: utf8 database: runner_development username: root password: socket: /tmp/mysql.sock |
The only required change is to add "host: 127.0.01" for the required database configuration. The updated fragment is shown below (with change highlighted):
| development: adapter: mysql encoding: utf8 database: runner_development username: root password: socket: /tmp/mysql.sock host: 127.0.01 |
Even though "host" is required for TCP connections but the database connection does not seem to work without this entry. The exact same application works without "host" entry on Windows and Mac OS.
Alternatively, you can always install the JDBC adapter as explained here.
Please leave suggestions on other TOTD (Tip Of The Day) that you'd like to see. A complete archive is available here.

GlassFish Day Beijing 2007 - By the Community, For the Community
Nov 3rd was the Community Day events as part of Sun Tech Days, Beijing. GlassFish, Open Solaris and NetBeans Day were conducted as part of the event. This blog provides a report on GlassFish Day.
The GlassFish Day started with approximately 100 people in the room. I personally enjoyed the entire day because I had to give only a 10 minute welcome session and no other talks :) However the emphasis of this particular event was to empower the local community about GlassFish so that they can help us spread the word further. And that was served very well. Most of the speakers were local and thus the title - By the Community, For the Community.
 |
It was very nice to meet Jim Jiang, Ada Li, Wang Yu, Liang Yan (Left to Right in the first picture) and Jason Huang (the second picture) who co-authored the first GlassFish book in Chinese. You can order the book from here. | |
 |
 |
|
The audience was very interactive through out all the sessions. Next is a list of the questions asked in each session (along with their answers).
Ada Li presented on GlassFish, Java EE 5 and their Future. The slides are available here and the questions are:
|
  |
Key-Yoe presented on OpenESB. The slides are available here and the questions are:
|
  |
Wang Yu & Jim Jiang presented on the Special Features of GlassFish. The slides are available here and the questions are:
|
  |
Vihang Pathak presented on Open Portal. The slides are available here and the questions are:
|
  |
Jason Huang presented on Open MQ. The slides are available here and Jason continued the discussion with attendees after the session finished just in time.
Tao Li presented on Metro - The Web services stack in GlassFish. The slides are available here and the questions are:
|
|
And the complete album from all the community events is available here:
All the presentations are also available here.
The event staff was meticulous and very helpful. They took care of all the details including getting the room ready on time, lining up the attendees and making sure the door is closed at all times. It was a great experience in all.
Next stop @ FOSS.IN.

As reported earlier jMaki and GlassFish, along with a host of other Sun-led open source technologies (NetBeans, OpenJDK, OpenDS, Project Indiana, etc.), were present at OSCON 2007 last week. I spent my entire 2 days at the jMaki booth which had a consistent stream of visitors on both the days. In case you are interested, here is what I presented:
The videos of other demos shown at the pod will be made available on this blog in the next few days.
I could not attend any of the sessions except some of the keynote sessions on second day. Of all the keynote videos the one I'd like you to watch is Overcoming Bias by Prof Robin Hanson. The professor, an Economic Theorist, talks about how cognitive bias cause software projects to slip. Some of the quotes from his talk are "Be more honest about writing code" and "If you really care about truth, you'll work at it and try to overcome bias".
Here are some pictures.
