The game helps to teach ( as well as to keep ) children how these winged migrants cross various states/countries/continentals. Good thing it does not need you to download anything on your machine. You would need a PC/Laptop/mobile device which has a browser with adobe flash player and an Internet connection.

An Architectural and Enterprise Scalability : highscalability.com

As usual while lurking on internet for the search of the knowledge, I come across a very good site highscalability.com.

In today's world of internet, scalability is ever important than before. Especially given the fact that there is growing popularity of social engineering, crowdsourcing and grid networking happening out there. And this is in addition to all those ecommerce, online games, media streaming and movie/video up/down loading and what not. :D)

Here are some definitions of Scalability:

scalability
The ability to scale to support larger or smaller volumes of data and more or less users. The ability to increase or decrease size or capability in cost-effective increments with minimal impact on the unit cost of business and the procurement of additional services.

Scalability
The ability to expand a computing solution to support large numbers of users without impacting performance.

Scalability
A term that refers to how well a hardware and software system can adapt to increased demands. For example, a scalable network system would be one that can start with just a few nodes but can easily expand to thousands of nodes. Scalability can be a very important feature because it means the entity can invest in a system with confidence they will not quickly outgrow it.

Given the fact that scalability encompasses not only hardware and software but it contains processes, performance, support for growing number of users and ultimately the "Money$". Due to that it is extremely important to understand Scalability - Architecturally as well as Enterprise wide. That is the purpose of this website High Scalability.

The website's has a get started using High Scalability link which leads to a dedicated page. This has lots of cool reasons why we need to have such site. This is a nice concept I have started seeing in some really wonderful websites and HighScalability does a great job explaining their existence. :D) This page tells what to expect, how to read , how to contribute etc.

The top navigation menu bar gives links to Home,Start Here, Ask a Question, Real Life Architectures, All Weblinks, Glossary, Jobs, Submit a Link, Advertise, Contact. While the left hand naviagation side bar allows to perform Create content,Recent posts,Useful Books,Useful Products,Useful Strategies,Useful Blogs,Useful Papers etc.

The website is simple to navigate and a great architectural resource for establishing high performing enterprise resources.

What exactly impressed me is the list of popular contents for all the time. And that list do cover lots of architectural examples from real life business and high traffic websites like Amazon.com, Twitter, Google etc. Below is a quick list for kind reference:


Each blog article on real life architecture contains information source, platform, architectural challenges, strategy to work around or to fulfill those challenges, performance tips/tricks and some solid examples.

Overall an excellent resource for technical architects, system administrators as well as performance tuning/optimization team resources.

Thanks to high scalability...you have made my weekend !!!

Cheers,,,

Need ondemand virtual secretarial service then go to "My Own Secretary"

Well, this world has clearly two different versions going on right now. One lives in Physical real form. While second has life in Virtual form on "Internet". That fulfills everything ...all the human desires...all the business needs and also provide the speed and automation. I am experiencing outsourcing getting boost and world becoming virtual global village first hand. Not only we can outsource technology and BPM work but also very personal and on demand secretarial work too. I think that is enough of introduction. :D) I am talking about virtual secretarial service.

I come across the My Own Secretary website. The website is very nice. The top navigation has beautiful portrait of lush green field with bluish gray clouds. It is followed with two column templates with left hand navigation menu and next to it various related contents.

Apart from simplicity and ease of navigation of the website, I am really interested due to the services these enterpruners are providing. They are an on-demand administrative/virtual secretarial service that provides support to small and large firms across the world. They offer services from secretarial support to business consulting. They also mention that they strive to meet every need for any business whether large or small. The company do provide many options but specialize in secretarial support. Interesting fact is that they provide instant and professional support to those in need of a virtual secretary with guarantee of 110% of quality in their work. Which is backed by a claim that If customer is not satisfied with services, then their service will be free.

The business concept is different and yet very focused. That is fully supported by their website and its design.

They have good points why somebody may like to hire them:

# WE SAVE YOU MONEY & TIME: We help you expand your resources without hiring extra staff so you can avoid paying employee-related taxes, workers' compensation and health insurance. Plus, you won't have to purchase and/or maintain additional office space and equipment. Also you can focus more on other aspects of your business.
# WE PUT OUR CLIENTS FIRST : We work on projects beyond the average 9-5 secretary would. We work on projects all times of the day therefore there is no 5'o clock cut-off time.
# OUR EXPERIENCE: We have over 10 Years of experience in the administration and marketing fields and our business & marketing plan developers' requirements is to obtain at least a Masters degree to achieve the best quality for our clients.
# SEND REFFERALS FOR DISCOUNTS: If you bring us a referral who purchase our services, you will then receive a discount up to 60% off on your next quote.
# ONLINE ACCOUNT ACCESS: You can access your quotes, invoices, and services rendered at anytime. You can also pay your invoices through your online account. Your password will be given to you, which you can change at any time

Very well though out reasons and creative business tactics behind it.

This above mentioned business reasoning is vouched by their portfolio of the customer and client's testimonials available on the website. That is neat.

If this makes you curious and want to get started with their services, you can check their getting started link or may be directly go to get the quote for the service. :D)

Overall very positive concept. Keep it up guys,

Tips & Tricks : how to encrypt the clear text boot.properties manually in WebLogic Application Server?

This tip is useful for two purposes.

  1. First is to recover from invalid system password situation and

  2. second to encrypt the clear text boot.properties.


The trick is to execute File Realm Class from core weblogic.jar file.

  1. First Identify a user and/or the set of users who needs to recover an invalid system password or to encrypt the clear text boot.properties manually.

  2. Second Create a properties file with extension .src and Add all the users need to be defined within this file.

  3. Third execute the File Realm class.


Here is how it is done:


Comments are allowed within the file (preceded by the # sign), and for each user within the set a corresponding entry must be defined on its own new line within the file using the following format:

user.<username>=<cleartext_password>

An example follows:

# define the WebLogic system to have the clear text password WebLogic
user.weblogic=weblogic


  • The newly created fileRealm input definition file (.src) can reside anywhere on the local file system.

  • When the input definition file has been created, the location of SerializedSystemIni.dat must be determined before the FileRealm class is executed from the command line.

  • SerializedSystemIni.dat provides an input seed (or salt) to the hashing phase of the encryption process, and that a password hashed with a specific salt can be successfully compared only to another password hashed by the same exact salt.

  • Therefore, the SerializedSystemIni.dat file, localized at the domain level and present within the security/ directory, has an explicit relationship to the passwords it hashes for the file realm of a given domain. Since WLS can't maintain a file realm in which the set of hashed passwords present have been seeded by different SerializedSystemIni.dat files, you should never mix passwords hashed by different salt files within the same file realm.

  • Set system class path to include the “weblogic.jar” file from the lib directory of the WLS installation.
    <<bea_home>>\server\lib

  • Invoke the utility from the command line as follows:
    java weblogic.security.acl.internal.FileRealm \ <path_to_output_file>\<path_to_salt_file>

  • <path_to_output_file>-
    The path to the output file given by the first parameter should be identical to that of the input definition file, with the .src extension dropped for the output file.

    For example, if you had created the input definition file as mentioned in above steps in a folder:

    c:\temp\user.properties.src,

    You’d now need to define the output file at

    c:\temp\user.properties.


  • This accommodates the way the FileRealm class internally handles the location of the input definition file - it concludes its location by using the same path and name of the output file, yet it assumes the input file has the .src extension added to it.

  • <path_to_salt_file>-
    This contains a hash key (called salt) to encrypt clear text password. This
    Parameter defines the location of the SerializedSystemIni.dat file.

  • It is under folder
    <<bea_home>>\user_projects\domains\<<domain name>>\security

  • Upon execution, the FileRealm class will generate its hashed password outputs into the file defined by the first input parameter.

  • After completion of command execution, open output file in notepad.


    • To recover invalid system password Select encrypted Password
    • &copy it from that output files and paste that encrypted password to FileRealm.dat which is under following folder:
      <<bea_home>>\user_projects\domains\>>domain>>\
    • After completion of copy-paste and file save of FileRealm.properties file, start WLS server to test the password recently set for the <<domain>> user. If the password recovery was successful, the server will properly start and WLS will operate as expected.


    • To encrypt the clear textSelect encrypted Password & copy it from that output files and paste that encrypted password to boot.properties.
