InfoSimulation Modernization Guide

InfoSimulation simulates DB2 workloads to test application performance under various conditions. It captures and replays DB2 activity, allowing for realistic testing without impacting production systems.

InfoSimulation is part of the INFO-OPTIMIZER suite, which provides a range of tools for DB2 performance management and optimization.

InfoSimulation primarily targets DB2 environments on z/OS. It is designed to work with the specific characteristics and requirements of DB2 on the mainframe.

InfoSimulation captures DB2 SQL activity using system traces and logs. It then replays this activity against a test DB2 subsystem to simulate production workloads.

Common operations include capturing DB2 traces, defining simulation parameters, executing simulations, and analyzing the results. Configuration files define simulation parameters.

InfoSimulation uses configuration files to define simulation parameters. These files specify the DB2 subsystem to target, the workload to simulate, and other simulation settings.

InfoSimulation uses standard z/OS communication protocols for interacting with DB2 subsystems. Specific ports depend on the DB2 configuration.

InfoSimulation allows organizations to test application changes and DB2 upgrades in a realistic environment, reducing the risk of production outages and performance problems.

By identifying performance bottlenecks before they impact production, InfoSimulation helps improve application performance and reduce resource consumption.

InfoSimulation enables more efficient testing cycles, reducing the time and cost associated with traditional testing methods.

InfoSimulation leverages z/OS security features for authentication and authorization. Access to simulation data and functions is controlled through z/OS security profiles.

InfoSimulation supports standard z/OS authentication methods, such as RACF, ACF2, and Top Secret. It integrates with the existing z/OS security infrastructure.

InfoSimulation uses an access control model based on z/OS security profiles. Access to specific functions and data is granted based on user roles and permissions defined in z/OS.

InfoSimulation provides logging capabilities to track simulation activity and identify potential issues. Logs can be analyzed to troubleshoot problems and improve simulation accuracy.

InfoSimulation is administered through a combination of z/OS commands and configuration files. User management is handled through z/OS security administration tools.

Key configuration parameters include the DB2 subsystem to target, the workload to simulate, and simulation execution options. These parameters are defined in configuration files.
