3rd March 2016 A Generic Approach to nVision Performance Tuning Scripts on Github: davidkurtz/nVision
Utility: PerfOptionSettingAnalysis.Fixed.zip
Documentation: PerfOptionsAnalysisToolDocumentation.zip
This document sets out a number of techniques that can be used to improve and stabilise the performance of PeopleSoft nVision reports. It is based on practical experience on real productions systems at a number of customer sites over a number of years.  However, it is a generic document, and makes general statements. Every customer is different, because their data is different and often their method of analysis differs.  Some of the techniques discussed are specific to the Oracle database, although in some cases, such as partitioning, similar features are available on other databases.

3rd January 2014 Oracle Date to Timestamp Conversion during PeopleTools Upgrade Download: gfc_desc_timestamp_index.sql
This document describes a script to convert Oracle date columns to Timestamps as required in PeopleTools 8.51 but only rebilding those indexes that reference those columns, rather than drop and recreate every index in the system, thus producing a significant saving of time during the upgrade.

19th April 2010 Practical Use of Active Session History
This document provides a brief overview of Active Session History (ASH) and then looks at the practicalities of how to use the ASH data to diagnose performance problems. It discusses the importance of instrumentation to make the ASH data useful, and how to query the ASH data to determine which SQL statements spent how long doing what, and therefore which need further examination.
26th January 2009 Factors Affecting Performance of Concurrent Truncate during Batch Processes
This paper describes an investigation into what happens in the Oracle database when concurrent processes frequently truncate working storage tables.  This can occur in PeopleSoft when multiple concurrent Application Engine processes truncate working storage tables. 'Time & Labor' processing is a typical example.  The paper presents some test results and makes recommendations to minimize the problem.

Updated 2.4.2009: Oracle Bug 4260477: ORA-08007: Further changes to this block by this transaction not allowed.  See Also Hemant's Oracle DBA Blog
