Peoplesoft Architecture

Let us look at PeopleSoft Architecture in easy to understand terms. 





Broadly speaking, PeopleSoft has 5 main components to support it's architecture.
a) Web Server:  it is a java-enabled web server to support browser transaction requests and the application messaging technology. It is also a collection of java servlets to handle wide range of PeopleSoft transactions. It is the web server that communicates with the client requests.

      b) Application Server: It executes business logic and issues SQL statements to the database. It consists of numerous services and server processes that handle transaction requests. It is also responsible for maintaining persistent connections with the databases. It is fair to say that application server is the heart of PeopleSoft Architecture.

      c) Database Server: It houses the database engine and PeopleSoft database. Database server can service many application servers. 

    

      d) Batch Server: It is the server where PeopleSoft Process Scheduler is installed and configured. It can be located on the same physical machine as the database server or on a dedicated machine or it can also be co-located with application server. 

      e) Application Designer: It is an integrated development environment that enables you to work with the numerous definitions of a business application in a single work area. In simpler terms, Application Designer is a tool that enables you to develop custom applications in PeopleSoft. 


      I can really go in a great detail for each of the above components or the architecture in general but I would love to answer the specific questions you have. Please leave your questions by posting a comment. I would promptly answer and cover them at great length.
