Dependency Analyzer Modernization Guide

Dependency Analyzer helps understand the relationships between DB2 objects and the SQL statements that access them. It identifies potential performance bottlenecks by tracing dependencies.

The tool analyzes application code to reveal the impact of changes to DB2 objects. This helps in impact analysis and reduces the risk of unintended consequences.

Dependency Analyzer can identify redundant or inefficient SQL statements by analyzing access paths and data usage patterns. This allows for optimization of SQL code.

Dependency Analyzer uses configuration files to define the DB2 subsystems and application libraries to be analyzed. These files specify connection parameters and data source locations.

The tool analyzes SQL statements embedded within application code, such as COBOL or PL/I programs. It parses the SQL syntax and identifies the DB2 objects referenced.

Dependency Analyzer generates reports that show the relationships between SQL statements and DB2 objects. These reports can be viewed in a graphical interface or exported to other formats.

By identifying and eliminating inefficient SQL, Dependency Analyzer can reduce CPU consumption and improve application response times. This translates to lower operational costs.

The tool helps in managing the impact of database changes, reducing the risk of application outages and data corruption. This ensures business continuity.

Dependency Analyzer provides insights into application dependencies, enabling better planning and execution of database migrations and upgrades. This minimizes disruption to business operations.

Dependency Analyzer leverages the security features of the underlying DB2 system. Access to the analysis results is controlled through DB2's authorization mechanisms.

The tool's audit logs record user activity and changes to configuration settings. This provides a trail for security auditing and compliance purposes.

Dependency Analyzer does not directly encrypt data. It relies on the encryption capabilities of the DB2 system to protect sensitive data.

Dependency Analyzer requires periodic maintenance to update its configuration files and ensure compatibility with changes to the DB2 environment. This includes refreshing data source definitions.

The tool's logs should be monitored for errors and performance issues. This helps in identifying and resolving problems before they impact application performance.

Dependency Analyzer can be integrated into automated build and deployment processes to ensure that database changes are properly analyzed and managed. This requires scripting and integration with CI/CD tools.
