Auto Threshold Setting

Auto Threshold Values

Threshold values* are automatically derived and set by applying Chebychev’s Theorem to system operation data gathered by Performance Insight

• Optimal value suitable for the system• Updated every day• Manual setting is also available

*To derive suitable threshold value, around 10 days for test operation is needed

Effective Method in Multiple-Server Environment

SQL Tuning - SQL Categorizer -

Categorize problematic SQL statement by tuning method

Kaizen Report SQL Categorizer

1　 SQL statements that may benefit from use of indexes or re-examining of the execution plan

2　 SQL statements that may benefit from the use of parallel query or by use of the Recycle buffer pool

3　 SQL statements that has heavy load of index range scan, or that which use the index with low cardinality

Tune this SQL statement using the SQL Scope

Architecture - Logging System -

Episode Layer(File System)Stores data by

monitoring/logging

XML fileCSV file

Minimum Load on the Database

Oracle Server

Agent Queue System

Monitoring Logging

Since information is collected from one Session by means of Agent Queue System,there is very minimum load on Oracle.

Logging LoadThe information collected from the logging Is stored in the file system called "Episode Layer" and can be accessed from each of PI5 functions.

Episode Layer

Performance Insight - Framework -

ClientOracle Server

Flexible Customization - Programming Language -

SQeeL

SQeeL is an open source programming language which can easily structure quick running and memory saving applications. It is especially effective for the development of databases and web applications.

The Web interfaces of PI are written in SQeeL. All sources for monitoring and operation can be accessed publicly.

　　 http://www.sqeel.org

POPSQL

POPSQL is developed as an interpreter language to be used mainly for batch process. Scheduled jobs in the PI5 are written by POPSQL.

For POPSQL language,

　＊ SQL interface for the access to database

　＊ Quasi-SQL interface for sequential files

　＊ Loading function to database (create new and update), unloading function are prepared.

Since scheduled jobs are available as sources written by POPSQL, they can be customized according to the operation policy of the customer's environment.

“SQeeL” and “POPSQL” are developed by Insight Technology, Inc.

Creating user-defined jobs based on the source codes of PI5.2
