Peoplesoft Component Interface interview questions & Answers

No. The web server that was delivered on the Tuxedo CD has absolutely nothing to do with WebLogic. WebLogic is a web application server that is designed for large-scale production websites.

The HTTP server on the Tuxedo CD was only there to provide a mechanism for launching the graphical Tuxedo administration console if the Tuxedo administrator didn't already have a web server in place. It was never intended for large-scale, production website use only for a system administrator or two.

The PeopleSoft Internet Architecture uses a web application server and anHTTP server. People Tools 8.12 and above include both BEA WebLogic andApache with Jserv. With PeopleTools 8.4, both BEA WebLogic and IBMWebSphere are bundled. Apache with Jserv is no longer a supported webapplication server combination.

Customers can choose which web applicationserver to run during installation time.In a mixed PeopleTools 8.1x and 8.4 environment, each PeopleTools installationshould have their own chain of web application server and application server,PeopleSoft Proprietary and Confidential Page 5and these can be on the same machine. For example, a PeopleTools 8.1xinstallation using Apache and Jserv could reside on the same machine as aPeopleTools 8.4 installation using IBM WebSphere. Care should be taken toensure that unique port numbers are assigned to each server chain.

The PIA Java servlets in PeopleTools 8.4 are coded to JavaSoft's Java Servlet API 2.0 and are fully compatible with Servlet API 2.2. It should be noted that the PeopleSoft Internet Architecture is supported only on the BEA WebLogic and WebSphere servlet engines.

Yes. WebSphere or WebLogic are used as the HTTP server and servlet engine. They are not used as middleware with the PeopleSoft Application Server. Tuxedo is always used with PIA, regardless of the HTTP server or Java servlet engine.

No. The PeopleSoft Mobile Agent architecture, which is used to support disconnected mobile applications, is only available in PeopleTools 8.4. The PeopleSoft Mobile Agent is dependent upon certain core technologies that were specifically developed for PeopleTools 8.4.

No. IBM WebSphere is certified on PeopleTools 8.4 only. Customer wishing to use IBM WebSphere with PeopleTools 8.1x may take advantage of an IBM WebSphere for early adopters program, created and managed by IBM. Further information about this program can be found in the whitepaper The IBM WebSphere 8.1x Early Adopter Program. Are there additional license requirements for IBM WebSphere

GetHistoryItems

Yes, databases can co-exist on the same physical machine. In most cases, thedatabases themselves can exist within the same RDBMS, however, it isimportant to verify that the database version required by PeopleTools 8.4 is thesame as for the current PeopleTools 8.1x implementation.

There are several scenarios that may exist when customers use the PeopleSoftEnterprise Portal with a mixture of 8.1x and 8.4 applications. Specificinformation on the use of the PeopleSoft Enterprise Portal in a blendedenvironment will be available in a forthcoming white paper, which will beavailable on Customer Connection.In general, the recommendation is to use the PeopleSoft Enterprise Portal 8.4with 8.1x and 8.4 applications, rather than an older version.

BEA and IBM provide plug-ins for many of the leading web servers. This allows the customer to use their own HTTP web server and WebLogic?s or WebSphere?s Java servlet engine. PeopleSoft uses this plug-in capability to support IIS. We have no reason to believe that there will be any issues with other web servers that WebLogic or WebSphere are able to work with through their plug-in architecture, but PeopleSoft GSC will not support these other web servers with PeopleTools 8.4

Some options:

1. Customize PS application (Yes)
2. Buy third party software (Yes)
3. Call PS Development Center for Enhancement (Yes)

A component interface can be mapped to multiple PeopleSoft components.

Yes, both PeopleTools 8.4 and PeopleTools 8.1x application servers can run ona single machine. It is important to ensure that there are no port clashes between the installations.

One of the core values of the PeopleTools development group is investment protection. The time, money and resources that you may have already invested in licensing another web server, training developers and administrators, building and deploying other web applications will not be compromised by this decision. How is this accomplished

To connect a report first we have to know about run control page. So that we can add the required fields over there and then passing those oprid and runctlid through the stdapi.sqc we can run an an SQR by including this SQC. This can be runned through the process sheduler. If directly we can go to the process sheduler request and made a request for the SQR. This happens only when the report repositry and distubution has been set properly. After making request we can run the process sheduler

Application Messaging is used by PeopleSoft applications to communicate withone another. This is true not just for 8.1x and 8.4 applications, but also between an 8.1x and an 8.4 application. For example, the HRMS 8.3 applications, which are based on PeopleTools 8.15, can communicate with Financials 8.4applications, which are based on PeopleTools 8.4, using Application Messaging. If specific issues materialize relating to the Application Messages published by certain applications, these new messages will be made available to customers.

Apache JServ was a servlet engine that was supported in PeopleTools 8.1x. This support has been removed from PeopleTools 8.4 for several reasons: v JServ is no longer an active product and is in maintenance mode and there are no longer any new official releases. v Our customers have exhibited a desire to use commercial products for mission-critical enterprise web application servers rather than open source solutions. Therefore, moving to support Tomcat is not seen as a reasonable solution. v Apache can still be used as an HTTP server with BEA WebLogic .

The Advanced Single Server Edition (AEs) of WebSphere provides the same core J2EE and Web Services programming model as the Advanced Edition (AE) with simplified administration. In the AE version WebSphere uses DB2 or other standard database to keep the configuration and runtime information to support very large farm of WebSphere servers. However, it is one more database to install, administer and maintain. The AEs version does not use the database and uses file based configuration in a way that is similar to BEA WebLogic. PeopleSoft and IBM WebSphere architects determined that AEs version would satisfy the deployment requirements of PeopleSoft customers and would make it easy for owning and administering PeopleSoft Applications based on WebSphere.

No. Both products are certified with PIA as of version 8.4 and work equally well. By offering both BEA WebLogic and IBM WebSphere, we give our customers more choices and flexibility to run PeopleSoft in their preferred environment.

A component exposes your pages to peoplesoft only.Moreover it helps us to define common properties for a set of related pages.

A component interface is a set of application programming interfaces (APIs) that you can use to access and modify PeopleSoft database information programmatically. PeopleSoft Component Interfaces expose a PeopleSoft component (a set of pages grouped for a business purpose) for synchronous access from another application (PeopleCode, Java, C/C++, or Component Object Model [COM]).

All popular http servers (reverse proxies) are supported. Please refer to the platforms database on Customer Connection for specific information on current certified platforms

Customers can set up clusters of BEA WebLogic or IBM WebSphere servers to do web server load balancing. In such scenarios, if an instance is down, requests are automatically routed to another instance.
