The debate occurs quite often on how to stack software in Cloud Computing solution (specifically Development & Test Cloud), amongst Service, Software & STG. I don’t complain the variety of software stack, as I like the more choices. I’m going to write out how my architectural solution looks.

I have one philosophy: When I could use OpenSource + Pure Blue software in my solution, I will do it without any hesitation.

IBM Development & Test Cloud solution is based upon Tivoli Service Automation Manager v7.2 for now. There’re 3 types machines in its Cloud environment. 2 of 3, in Managing environment , are Management Server & Administrative Server. The last one, in Managed environment, is the managed system(s).

My only rule to follow is to check the product infocenter, which tells the truth of technology & product. The one is http://tinyurl.com/tivsam (I talk about x only for my current engaged case @ one Telco customer in Beijing)

For Management Server, we have 2 choices on 64 bits x – RHEL5.4 or SLES10.2

For Administrative Server, SLES10.2 is ONLY our choice for Linux. Obviously Microsoft Windows isn’t in my list either. The reason is clear.

For Managed environment on x, we get rid of VMware and we have RHEL5.4 and SLES10.2 (CentOS isn’t in my list, due to lack testing & support)

To combine the above consideration, I use SuSE Linux Enterprise 10.2 in management environment and Redhat Enterprise Linux 5.4 in managed environment.

What are the specifications for the sizes of images?

For the Beta (Poughkeepsie) environment:

For the Pilot (Southbury) environment:

gedit-editor > apps > totem > buffer-size | network-buffer-threshold

Change buffer-size = 10 & network-buffer-threshold = 10

Stack: SeaMonkey 1.1.15 in Ubuntu 9.04

Symptom: Socks Proxy is set, but doesn’t work

Open SeaMoney > about:config in URL bar > type

network.proxy.type

then set the value = 2

Installed cups-pdf in Ubuntu 9.04 and changed the following in /etc/cups/cups-pdf.conf

Out ${HOME}/Desktop

Restarted /etc/init.d/cups, still received

Could not open the file /home/{you}/Desktop/273_.pdf

in /var/log/cups/error_log

The solution is, in /etc/cups/cups-pdf.conf, change to

Out ${HOME}/PDF

and create PDF directory under your home directory

Disable in gconf-editor

Or in command line:

To disable >
gconftool -s --type bool /apps/update-notifier/auto_launch false

To enable >
gconftool -s --type bool /apps/update-notifier/auto_launch true

Stack

Host OS > Ubuntu 9.04

Guest OS > Windows XP

VirtualBox > 3.0.0

Hardware > ThinkPad T43, single CPU, 2G memory

Symptom: Windows XP hangs during shutdown

Resolution: Change the setting as the followings

VT – Enabled

Nested Paging – Disabled

ACPI – Enabled

IO ACPI – Disabled

PAE – Disabled
