IMS Performance Analyzer

The architecture of IMS Performance Analyzer (IMS PA) is centered around three main components: the Data Collector, the Report Generator, and the User Interface (CLI). The Data Collector is responsible for extracting data from IMS log files. It parses the log data, filters relevant information, and prepares it for analysis.

The Report Generator then processes this data to create various performance reports. These reports include transaction response time analysis, database performance metrics, and CPU utilization reports. The User Interface is a command-line interface (CLI) that allows users to interact with the system.

Users use the CLI to specify report types, data sources, and output formats. The communication between these components is primarily file-based. The Data Collector writes processed data to intermediate files, which the Report Generator then reads to create reports.

The system uses IMS log files as the primary data source. These log files contain detailed information about IMS transactions, database activity, and system resource usage. Configuration files are used to define data sources, report parameters, and system settings.

The system does not have any specific network requirements or open ports. The z/OS security system (RACF, ACF2, or Top Secret) handles authentication and access control. IMS PA leverages the existing z/OS security infrastructure for user management and access control.

The reports generated provide valuable information for stakeholders to understand system performance and make informed decisions. Compared to other tools, IMS PA offers more detailed analysis and better integration with the IMS environment.
