1 Performance Management Tool for Oracle database

2 Master the art of Database Kaizen As an organization grows, it must respond to ever-changing business needs by ensuring continuous operation of mission critical systems. However, database systems evolve constantly, and performance degradation is inevitable due to accumulating changes and rise in complexity. Today, most organizations face the database management challenge: to accommodate exponential data growth together with environmental complexity brought by increased number of applications, features, users, and changing compliance requirements. This is a typical situation where the process of Kaizen (Continuous Optimization) can improve business performance. Kaizen - A management philosophy of "continuous improvement" developed in Japan to improve quality of products and streamline operations. Although Kaizen is frequently perceived as being a production technique, it is a concept of equal benefit to all other aspects of business activities. Performance Insight applies the concept of Kaizen to database management. Performance Insight allows database professionals to monitor the availability and performance of complex database systems in a consistent and efficient manner. Performance Insight simplifies IT management for today's complex environments and brings out the true potential of systems, helping you realize a system of high performance and availability.

3 REPORT Kaizen Report Knowledge Center Identify bottlenecks immediately A database administrator needs a high level view of all available resources and how they are being utilized in order to identify and pinpoint the root cause of performance degradation. However, identifying the various sources of degradation and performance issues can be a complex and time-consuming effort. Performance Insight automatically generates Kaizen Reports by statistically analyzing collected data. The report creates a complete overview of an individual server covering the following categories: CPU/Memory,, Environment, Disk, SGA, and Space. Identified problems are prioritized in the order of severity, which are further categorized to a radar chart for easy analysis. The hexagon chart enables administrators to identify the cause of problems objectively and intuitively. A database administrator can also drill down to detail including historical analysis of each resource and receive recommendations on how to optimize performance. Repository of database solutions and terminology Knowledge Center is a repository of detailed instructions and suggestions for resolving problems reported by Kaizen Reports. It also serves as a concise definition repository for commonly used Oracle terminology. Knowledge Center stores much information, including tuning methods and advice from experienced consultants, all of which help in effective management of Oracle databases. Kaizen Report Screen (Summary): Identify performance degradation and cause of problems from the radar chart Knowledge Center Screen: Provide suggestions and concise definitions relevant for resolving problems Kaizen Report Screen (SGA): Identify root cause of problems through extensive drill-down information

6 ACTION Action Navigator Categorizer Navigate your way to problem resolution Action Navigator provides detailed instructions and suggestions on how to resolve problems and optimize database performance. It is also capable of launching other powerful tools based on user defined conditions and problems. The Action Navigator allows users to add and execute user-defined tasks to resolve problems or optimize performance. For instance, if Performance Insight detects extension of tables, Action Navigator provides guidelines on table maintenance. The Action Navigator will recommend monitoring the growth of objects such as extents, blocks, and records and to discern the growth trend. Action Navigator also lets the administrator launch tools to investigate and resolve problems. Expert consulting and support for tuning Using its built in knowledge base, Performance Insight identifies heavy and problematic statements that degrade database performance. These statements are then categorized into three tuning methods. Due to the simplification and organization, this categorization methodology allows database administrators to tune and optimize performance degradation quickly. Through DB Scope, Performance Insight allows administrators to examine the execution plan and rapidly analyze object dependencies including tables, tablespaces, and indexes DB Scope Method 1 Method 2 Method 3 Minder Console Action Navigator Object Monitor 1.
