ATG - basic concepts of ATG

This blog is for the ATG beginners to get some basic overview about ATG. I just given the ATG concepts as a list of numbered points for the ease of understanding.

1. At the framework level, ATG is a
              java based application platform for hosting web-based applications, as well as RMI accessible business components,
              with an ORM layer,
              a component container,
              an MVC framework,
              and a set of tag libraries for JSP.

2. Art Technology Group(ATG)'s Dynamo Application Server (DAS) is a Java EE compliant application server. DAS is no longer actively developed as ATG recommends using other Java EE applications servers for its products such as BEA WebLogic, JBoss or IBM WebSphere.

3. Prior to ATG 2007, JHTML was used instead of JSP for view purpose. JHTML stands for Java HTML. This is a page authoring system developed at Art Technology Group (ATG).Sun Microsystems licensed parts of this technology and developed the JSP system from the ATG page compilation system.

4. ATG mainly works on the basis of following concepts:
       Nucleus
      Droplets
       DSP Tag Libraries
      Form Handlers
      Repository

5. Nucleus:  Nucleus is server side java beans. To use ATG platform functionality, a web application needs to start Nucleus by invoking atg.nucleus.servlet.NucleusServlet. It’s essentially an object container that manages the lifecycle of POJOs using reflection and dependency injection.

6. Droplet: Droplet is a Servlet and is also a Java bean. Advantage of droplet is that you can have multiple Droplets in a single page. Droplets can be nested and can pass parameters to each other.

7. DSP Tag Libraries: Dynamo Server Pages is a set of tags that ATG provides, that allow us to access the functionality provided by the Dynamo Application Framework such as accessing Nucleus componenets, passing parameters,...

8. Form Handler: ATG Form Handlers are components for validating and processing html forms, calling business components and managing flow between a limited set of pages (e.g. success/error), so a bit like Struts Action classes in that they mediate between the view and model. ATG provides hundreds of readymade form handlers for performing all sorts of tasks, like updating a customer profile, managing your shopping cart, checking out, or interacting with a repository.

9. Repository: A repository is a data access layer, which gives a generic representation for a data store.

10. Logging: ATG also provides a logging framework which is essentially a wrapper over log4j. A nice feature of this is that you can turn on logging for a particular component within a web browser. ATG also provides a performance logging framework which you can plug into components, and is very useful for identifying bottlenecks or problem areas in your code as it lets you browse and drill down into the performance timings and memory usage of components.

Following are the main administaration UIs provided by ATG

11. Dynamo administration: All the ATG components can be browsed and the properties can be modified at run time using dyn/admin. By clicking "View Service Configuration",  you can view the component in different modules in the hierachy.

12. ACC > ATG Control Centre: Browse and edit component configurations, Build scenarios, View and edit repository data. ATG provides a unified view of your application's data through the ATG Control Center which is a graphical user interface that uses the Repository interfaces to allow users to create, query, update, and remove repository items.

13. BCC >  Business Control Center: The ATG Business Control Center is a browser-based interface that you can use to create and edit many of the elements required to set up and maintain an ATG-based web site. This can be used for doing the Search Administration  and Content Administration.

14. CA > Commerce Administration: ATG Commerce Assist is a customizable and deployable customer service application that enables a Customer Service Representative (CSR) to perform the following tasks for an ATG Commerce site: Create and manage organization profiles (ATG Business Commerce only) , Create and manage customer profiles, Create and manage orders,  Issue refunds and exchanges, Process returned items, Research customer activity.

ATG Search - search engine tuning settings

In this blog, I am going to list the best tuning settings for ATG Search engine. The AESoapConfig.xml, AESoapWaspConfig.xml  and AEConfig.xml are the xmls referred below and you can find it @  <ATG_DIR>\<Searchx.x>\SearchEngine\<operating_system>\bin\ folder. (1)  Make sure that the AESoapConfig.xml's rwTimeout is less than or equal to routing's readTimeoutMs. You could find the routing's readTimeoutMs @ atg\search\routing\SearchEngineService component.               rwTimeout is the  length of time in seconds to wait before a read or write operation times out on an active connection. The number can be decreased to improve performance. However, a value that is too low could cause slow connections to be prematurely closed. (2)  Adjust the number of engine threads to match the number of CPUs available to the engine. Note that the minimal value for maxThreads and maxSpar...

ATG CA - different activity sources used @ BCC

Read about how a new link can be added in BCC home page @  http://tips4ufromsony.blogspot.com/2012/03/atg-ca-bcc-home-screen-how-to-add-new.html Normally an ActivitySource.properties file define the set of actions that it supports under a genericActivityDefinitionFile. But some ActivitySource.properties  define the actions  using the workflowActivityDefinitionFiles. For example consider the default "Content Administration" ,  "SearchAdministration",  " Merchanding "  and "Personalization" options in BCC homepage. Below I listed the ActivitySource.properties and other properties for these links. To get all these activitysource names, just take the / atg/bizui/activity/ActivityManager  component @ dyn/admin. Content Administration ActivitySource  --> /atg/bizui/activity/PublishingActivitySource genericActivityDefinitionFile Search Administration ActivitySource  --> /atg/bizui/...

In the month April 20xx, we will give the investment details to the employer (in our employer specified portal) for the FY 20xx – 20xx+1. In the month January 20xx+1, we will give the investment proof details , Rent receipts… to the Employer Finance Department for the FY 20xx – 20xx+1.

IFSC and MICR code

For internet banking third party transfer you might need the IFSC or MICR code. IFSC or Indian Financial System Code is an alpha-numeric code that uniquely identifies a bank-branch participating in the NEFT system. MICR or Magnetic Ink Character Recognition is a character recognition technology used primarily by the banking industry to facilitate the processing of cheques. Please find below some useful links to get the IFSC and MICR code for a bank branch: http://rbi.org.in/scripts/neft.aspx http://rbidocs.rbi.org.in/rdocs/content/docs/67440.xls http://bankifsccode.com/ http://banks-india.com/ifsc-code.php http://en.wikipedia.org/wiki/Indian_Financial_System_Code http://en.wikipedia.org/wiki/Magnetic_ink_character_recognition
