Audit Reports in PeopleSoft

For truly understanding the purpose of the peoplesoft audit reports, it is required to back-track a little to recall on what kind of data will be available in the peoplesoft database. 

The peoplesoft database is basically a combination of three layers, 

1. The Database System tables.

2. The Peopletools tables.

3. The Peoplesoft application tables.

The database system tables consists of all the system metadata and the core tables which is required for the proper functioning of the database.

The peopletools tables is populated during the creation of the peoplesoft application. These tables generally start with a PS*** example PSOPRDEFN.

The application tables are also created during the implementation phase of the application. The type of application tables depends upon what kind of data is imported such as it could be HRMS, FSCM and so on. These tables begin with a PS_*** example PS_JOB.

Now that we are clear on what kind of data the Peoplesoft database is composed of we can move on to learn about the peoplesoft audit reports.

Audit reports are generally used pre or post an upgrade or any changes in the application. This is used to check the sanity of the database. The below listed are the reports which are available for use.

1. Alter Audit

2. SYSAUDIT 

3. DDDAUDT

The alter audit is not a process, it is created using application designer by filtering all the records that will be required to be part of this audit and then using alter options as alter in place and building the selected objects with execute and build options. This will help to understand which all tables require an alter to be processed in the database.

The sysaudit is used to check all the orphaned objects which are present in the database. For example there could be a piece of peoplecode which is not being referenced anywhere.

The dddaudit is an sqr program which is used to check the differences in data between the system tables and the peopletools and application tables.

SchedulerTransfer Servlet error

ISSUE:
The PeopleSoft process has completed, but the report posting status has completed with Not Posted. When the message log of the process was checked the error message says Scheduler Transfer error.

Error getting report repository location. (63,85)

SchedulerTransfer Servlet error.

PSEXA failed to post files to the report repository. Server

scheduled to try again on 2013-11-18-10.48.57.782504.

CAUSE:
This issue occurs because the servlet SchedulerTransfer which is used be the application for posting the reports from the peoplesoft process scheduler to the web server repository has failed.

SOLUTION:
This issue can be resolved by manually invoking the SchedulerTransfer servlet and resending the contents of the process.

PeopleSoft Application Server

What is the PeopleSoft Application server?

The Application server is the portion of the Peoplesoft pure internet architecture which is used to handle the business logic and bulk of the workload of the PeopleSoft system.

What is the technology of the Application Server?

Oracle Tuxedo is used to process transaction requests. Oracle Jolt interfaces Java and makes the tuxedo technology to extend to web based environments.
The server processes can be configured for unique purpose, some processes can be used to handle the browser data, while others can be used for Integration broker requests.

How to make use of the Application Server?

The web server will have a configuration.properties file which contains information about the application server to which it needs to connect. The IP address and Jolt Port of the application server is mentioned in that file, now the requests will get directed to the application server which has been configured.

The application server can have multiple domains each one containing multiple server processes running. The request from the webserver will get forwarded to the application server which has the appropriate Jolt port as mentioned in the configuration.properties file. Each application server domain will have an appropriate psappsrv.cfg file which will be created when the domain is deployed. The psappsrv.cfg file contains all the domain information, including the JSL port and the database connectivity details.

How to handle the application server?

The application server is handled using the psadmin utility, which is created as part of the people tools installation. The psadmin utility helps in creating, configuring,deleting and maintaining the application server domains.

PeopleSoft Web Server

What is the PeopleSoft Web Server?

The PeopleSoft Web server is a Java-enabled web server which handles the browser transactions and also supports the PeopleSoft messaging technology. It basically contains a collection of servlets to handle a range of PeopleSoft transactions.

We will discuss on the below sections:

1. Server Software Elements:

When PeopleSoft software is installed, a variety of PeopleSoft web servlets are installed in the web server. A supported servlet container must be installed to use these servlets in our application. The below listed software run on the PeopleSoft web server,

a. Web Services -- The web services manage the web server software which should be Oracle WebLogic or IBM Websphere.
b. Servlet Engine -- The servlet engine is tied to the web services software, but in some cases it can be installed separately as well. The servlet engine contains all the PeopleSoft servlets.
c. Java Servlets -- Java is a platform independent programming language which is used for creating web based applications. The web server contains servlets which require java executables to be invoked.

2. The PeopleSoft Servlets:

The PeopleSoft servlets which are present in the web server are as below,

a. Portal Servlet -- The portal servlet is used to manage the requests and formatting when the client users access PeopleSoft via the Peopletools portal. It is used to handle homepage personalizations, content searches and content access.
b. Integration Gateway Servlet -- This servlet offers publish/subscribe messages between the message nodes. The gateway is used to handle PeopleSoft to PeopleSoft messages, third-party to PeopleSoft messages and PeopleSoft to third-party messages.
c. Report Repository Servlet --  This servlet helps in managing the output of the processes run using the batch server. It distributes the output reports such as crystal reports so that it can be accessed easily over the internet.

3. Oracle Jolt:

Oracle Jolt forwards the requests received by the PeopleSoft servlets to the application server. The Oracle Jolt is an extension of the tuxedo technology over the communication layer between the Java based web server and the C++ based application server. So basically the web browser sends HTTP request to the web server, the servlet in the web server connects to the Jolt port configured in the configuration.properties file of the web server and Oracle Jolt converts the request into a format understandable by Tuxedo which runs in the application server, which in turn will fire the SQLs against the database to fetch the desired output. The below Diagram explains the need for Oracle Jolt and Tuxedo.


Note: The Oracle Jolt and Tuxedo should both be installed in the application server.

Introduction to PeopleSoft and PSAdmin

What is PeopleSoft?

PeopleSoft is an ERP(Enterprise Resource Planning) software, which provides Human Resource Management Systems (HRMS), Financial Management Solutions (FMS), Supply Chain Management (SCM), Customer Relationship Management (CRM), and Enterprise Performance Management (EPM) software, as well as software for manufacturing, enterprise performance management, and student administration to large companies, governments, and organizations.

In the year 2005, there was a hostile acquisition of PeopleSoft by Oracle corporation. Since then the PeopleSoft brand and market line are marketed by Oracle.

Who are the founders?

PeopleSoft was created by David Duffiled and Ken Morris in the year 1987. After it got acquired by Oracle, David Duffield moved on to create a new cloud based ERP software system called Workday.


What are the technologies involved?

PeopleSoft is a combination of different technologies spread over what is called the "PeopleSoft Pure Internet Architecture". Predominantly the underlying programming languages are C++, Java, tuxedo..etc. PeopleSoft supports multiple database platforms such as Oracle, DB2, Sql Server.


What are the basic skills required to learn PeopleSoft Administration?

Some of the skills required for PeopleSoft Administration are as listed below,

1. Basic understanding on client-server architecture.
2. Knowledge on working in Unix/Linux and Windows based server environments.
3. Working with tuxedo.
4. Understanding web containers such as Oracle Weblogic, or IBM Websphere.
5. Knowledge on Oracle, DB2 or SQL Server database servers.

What are some of the roles of a PeopleSoft Administrator?

1. Installing and maintaining the PeopleSoft Pure Internet Architecture, and deploying the domains.
2. Performing upgrades and applying patches/bundles.
3. Monitoring the database, performing SQL tuning, there are some roles which will ask the PSAdmin to perform DB Backup and restore.
4. Supporting the development team on testing and migrating custom code changes to production environment.
