IOMAN for DB2

Candle Corporation Not Supported z/OS

Performance Monitor Db2

Vendor

Candle Corporation

Product Overview

The architecture of IOMAN for DB2 comprised several key components designed for performance monitoring on z/OS. The Data Collector was responsible for gathering performance metrics from DB2 system tables and internal monitoring mechanisms. The Analysis Engine processed the collected data, identifying performance bottlenecks and generating insights.

The Reporting Module provided various reports, accessible via the command-line interface (CLI). Communication between components occurred through internal interfaces optimized for the z/OS environment. Data was stored in VSAM datasets for historical analysis.

Configuration was managed through JCL and parameter datasets. The CLI provided commands such as `START IOMAN`, `STOP IOMAN`, `DISPLAY METRICS`, and `GENERATE REPORT`. IOMAN for DB2 is no longer supported; users should consider migrating to modern DB2 performance monitoring solutions like IBM Db2 Performance Expert for z/OS or BMC AMI Ops Monitor for Db2.
