Will Tuxedo continue to be used in a PeopleSoft/WebSphere or PeopleSoft/WebLogic environment?
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.

Can a PeopleTools 8.4 and a PeopleTools 8.1x database run on the same machine?
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.

Can a PeopleTools 8.4 and a PeopleTools 8.1xapplication server run on the same machine?

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.

How does the PeopleSoft Enterprise Portal workwith 8.1x and 8.4 applications?
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.

For the servlet layer on the web server, what version of the Java Servlet API are the PIA Java Servlets coded to with PeopleTools 8.4?
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.

IBM How should Web Application Servers be used with PeopleTools 8.1x and PeopleTools 8.4?
The PeopleSoft Internet Architecture uses a web application server and anHTTP server. PeopleTools 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.

Why did PeopleSoft bundle IBM WebSphere Advanced Single Server Edition rather than Advanced Edition?
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.

Will the PeopleSoft Internet Architecture, now that it embeds BEA WebLogic and IBM WebSphere, work with my other corporate web servers and tools?
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

Is BEA WebLogic the same thing as the web server that was previously on the Tuxedo CD?
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.

Are disconnected mobile applications supported in PeopleTools 8.1x?
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.

Is WebSphere certified on PeopleTools 8.1x?
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

Are there advantages or disadvantages to using BEA WebLogic over IBM WebSphere or vice versa?
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.

Is web server load balancing supported with PeopleTools 8.4?
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. For more information on high availability and clustering with WebLogic, WebSphere and other web servers.
