Peoplesoft Architecture Step by step explanation

Peoplesoft Architecture:


         1. Browser
         2. Web server
         3. Application Server
         4. Process Scheduler
         5. Database Server



Flow:


1 .Web browser has a link which interpreted as url address which 
includes: Server name, Http port,servlet and domain name

2. Servlet running in the servlet engine interprets request & comes up 
with a list of objects that are required to build a page. A java enabled web 
servers is required to support web browser.

3. The PS servlets on the webserver transmits requests through a JOLT 
connection. JOLT - Java Online Transaction.

4 .In App servers JSL listens the request & JSH will handle the request.
     - JREP is an process that is used to convert jolt messages into tuxedo messages.
     - Because BBL can understand only TUXEDO messages.
   - BBL(Bulletin Board Liasm) it handles client requests, listeners, handlers & queues
                - BBL will take request & route it to the appropriate peoplesoft processes.
                - BBL will directs the communication traffic( It routes the requests which process is idle)

5. Peoplesoft process converts service requests into sql statements to the 
             Database.

6. Sql statements sent to DB

7. Data requested is supplied by the Database.

8. People Soft Process constructs html page out of object data.

9. Tuxedo acknowledges receipt of data & closes connection with the 
People Soft process.

10. Data forwarded by tuxedo to requesting Java Servlet on webserver.

11. Servlets forwards page requested by browser.

12. Browser views pages.
