How does Expetune DB analyze access paths?

Expetune DB analyzes access paths used by DB2 to retrieve data. It identifies inefficient access paths that lead to full table scans or excessive I/O operations. It provides recommendations for creating or modifying indexes to improve access path efficiency.

What configuration files are used by Expetune DB?

Expetune DB uses configuration files to define DB2 subsystem parameters, SQL statement thresholds, and reporting options. These files allow users to customize the analysis process to meet specific requirements.

What APIs does Expetune DB expose?

Expetune DB does not expose public APIs. It primarily functions as a standalone performance analysis tool.

How does Expetune DB communicate with DB2?

Expetune DB communicates with DB2 using standard DB2 call interfaces. It retrieves Explain data and SQL statement information directly from DB2.

How does Expetune DB provide business value?

By identifying and optimizing inefficient SQL statements, Expetune DB reduces CPU consumption, improves application response times, and lowers overall IT costs. It helps organizations achieve better performance with existing infrastructure.

How does Expetune DB improve the performance of business applications?

Expetune DB helps organizations improve the performance of critical business applications that rely on DB2 databases. By optimizing SQL and access paths, it ensures that applications can handle increasing workloads and deliver timely results.

Does Expetune DB reduce the need for hardware upgrades?

Expetune DB helps reduce the need for costly hardware upgrades by optimizing existing SQL and database configurations. It allows organizations to maximize the utilization of their current infrastructure.

What access control model is used by Expetune DB?

Expetune DB uses the access control model provided by DB2. Access to DB2 data and functions is controlled through DB2's grant and revoke mechanisms.

What encryption is used by Expetune DB?

Expetune DB does not directly encrypt data. It relies on DB2's encryption capabilities to protect sensitive data at rest and in transit.

What monitoring and logging capabilities exist in Expetune DB?

Expetune DB provides monitoring and logging capabilities to track SQL analysis activities, identify potential performance issues, and ensure system stability. Logs can be reviewed to identify trends and troubleshoot problems.

What administrative interfaces are available for Expetune DB?

Expetune DB is administered through a combination of ISPF panels and batch jobs. ISPF panels are used for interactive configuration and analysis, while batch jobs are used for automated analysis and reporting.

How is user management handled in Expetune DB?

User management in Expetune DB is handled through z/OS security mechanisms, such as RACF. Access to Expetune DB functions is controlled through RACF profiles and permissions.

Product Overview

Expetune DB is a performance analysis tool designed to identify and resolve SQL and DB2 inefficiencies. It analyzes both static and dynamic SQL, gathers Explain data without requiring SQL execution, and provides detailed access path analysis. This allows for proactive identification of performance bottlenecks before they impact production systems.

**Architectural Components:** * **ISPF Interface:** Provides interactive panels for configuration and analysis. * **Batch Processor:** Automates SQL analysis and reporting. * **DB2 Interface:** Communicates with DB2 using standard DB2 call interfaces.

**Communication:** * The ISPF interface allows users to interactively configure analysis parameters and view results. * The Batch Processor submits SQL analysis jobs to DB2. * The DB2 Interface retrieves Explain data and SQL statement information directly from DB2.

**Data Storage:** * Expetune DB uses DB2 to store configuration data, analysis results, and historical performance data. **Security:** * Expetune DB leverages the security features of the underlying z/OS and DB2 environments. It relies on DB2's authentication and authorization mechanisms to control access to sensitive data and functions.

Access to DB2 data and functions is controlled through DB2's grant and revoke mechanisms. Expetune DB helps optimize DB2 performance by identifying inefficient SQL statements and access paths. Competing products include IBM Db2 Query Monitor and BMC SQL Performance for DB2.

Frequently Asked Questions

What are the core capabilities of Expetune DB?

Expetune DB analyzes static and dynamic SQL statements to identify performance bottlenecks. It gathers Explain data without executing the SQL, analyzes access paths, and highlights inefficient SQL code.

How does Expetune DB improve database performance?

Expetune DB identifies inefficient SQL statements, analyzes access paths to DB2 data, and provides recommendations for optimization. It helps reduce CPU consumption and improve application response times.

Can Expetune DB analyze both static and dynamic SQL?

Expetune DB can analyze both static SQL embedded within application programs and dynamic SQL submitted at runtime. This comprehensive analysis helps identify performance issues across the entire application landscape.

Does Expetune DB require SQL execution to gather Explain data?

Expetune DB gathers Explain data without requiring the actual execution of SQL statements. This allows for performance analysis in a non-production environment without impacting production systems.
