Plan Analyzer for Db2 Modernization Guide

Plan Analyzer for Db2 analyzes SQL access paths to identify performance bottlenecks. It provides recommendations for SQL and database tuning to improve query performance.

Plan Analyzer for Db2 uses Db2's Explain facility to capture access path information. It then analyzes this data to identify inefficient SQL statements and recommend improvements.

Plan Analyzer for Db2 supports various Db2 objects, including tables, indexes, views, and stored procedures. It can analyze SQL statements that access these objects to identify performance issues.

Plan Analyzer for Db2 provides recommendations for index creation, SQL statement rewriting, and database configuration changes to improve SQL performance.

Plan Analyzer for Db2 uses the Db2 Explain statement to capture access path information. The Explain statement output is then analyzed by Plan Analyzer to identify performance bottlenecks.

Plan Analyzer for Db2 can be configured using ISPF panels or batch jobs. Configuration parameters include database connection information, Explain table definitions, and analysis options.

Plan Analyzer for Db2 uses standard Db2 interfaces for accessing database objects and capturing Explain output. It does not expose any custom APIs.

Plan Analyzer for Db2 requires access to the Db2 catalog tables and Explain tables. It also requires authorization to execute the Explain statement.

Plan Analyzer for Db2 generates reports that highlight performance bottlenecks and provide recommendations for improvement. These reports can be viewed online or printed.

Plan Analyzer for Db2 helps reduce CPU consumption by identifying and optimizing inefficient SQL statements. This can lead to significant cost savings, especially in high-volume transaction processing environments.

By improving SQL performance, Plan Analyzer for Db2 can reduce application response times and improve user satisfaction. Faster applications can lead to increased productivity and revenue.

Plan Analyzer for Db2 helps ensure that Db2 resources are used efficiently, maximizing the return on investment in Db2 infrastructure. Optimized SQL reduces the load on Db2 servers, allowing them to handle more transactions.

Plan Analyzer for Db2 can help identify poorly written SQL statements that may be vulnerable to SQL injection attacks. By optimizing SQL and enforcing coding standards, Plan Analyzer can improve application security.

Plan Analyzer for Db2 leverages Db2's built-in security features. Access to Plan Analyzer functions is controlled through Db2 grants and privileges.

Plan Analyzer for Db2 supports standard Db2 authentication methods, including user IDs and passwords, as well as external authentication mechanisms like RACF.

Plan Analyzer for Db2 does not encrypt data at rest or in transit. However, it relies on Db2's encryption capabilities to protect sensitive data.

Plan Analyzer for Db2 logs all user activity and SQL analysis results. These logs can be used for auditing and security monitoring.

Plan Analyzer for Db2 is administered through ISPF panels and batch jobs. User management is handled through Db2's security administration facilities.

Plan Analyzer for Db2 provides online monitoring capabilities through ISPF panels. These panels display real-time information about SQL analysis activity and resource consumption.

Plan Analyzer for Db2 generates SMF records that can be used for performance monitoring and capacity planning. These records contain information about SQL execution times and resource usage.

Plan Analyzer for Db2 requires regular maintenance to ensure that the Explain tables are properly defined and that the analysis options are configured correctly. Maintenance tasks can be automated using batch jobs.
