What are Important Files on PeopleSoft Application Server

As you would know that PeopleSoft has several different components which have their own role to play in PeopleSoft Architecture. These components have different file structures and contains important executables and configuration files. We have listed the directory structure of these major PeopleSoft components and compiled a list of important directories and file within them.

Below are the major components of PeopleSoft System.
1.File server
2.Web server
3.Application Server
4.Tuxedo
5.Batch server / Process scheduler
6.Database server

This post will discuss about the PeopleSoft Application Server directories and configuration Files.

• Application server is responsible in communication with the database
• Application server cannot exist alone; it has to co-exist with tuxedo.
• Application server is a collection of processes such as PSAPPSRV, PSQRYSRV, PSSAMSRV etc,
• There can be more than one domain configured in an Application server
• Each domain has its own key configuration files

Psappsrv.cfg:   This configuration file contains the information about the Jolt/Wsl port numbers, domain settings and all other important details pertaining to the domain.

Psappsrv.ubb: PSADMIN invokes a PeopleSoft developed sub-program named UBBGEN, which takes the configuration parameters and builds the file psappsrv.ubb.

Psappsrv.ubx:  This is a domain template file which has all the parameters.UBBGEN will open the file psappsrv.ubb, process it and produce this file.

Psappsrv.val:    This is a validation file which validates the entry in the configuration file such as the database type, jolt port limitation etc.

Psappsrv.env:     This file has the information about the path to appserver executables and path information for database connectivity.

PSTUXCFG:   This is the configuration file generated by loading the psappsrv.ubb file using the tuxedo load command (tmloadcf). This is a binary file and is used while the domain is booted.
