InfoUnload is a utility designed for high-speed unloading of DB2 tables on z/OS. It is a key component in data management strategies, often used with InfoLoad for efficient backup and restore processes. The architecture includes components for data extraction, formatting, and output management.
These components communicate through internal interfaces and shared memory to optimize performance. Configuration is managed through control statements and configuration files. Control statements define the tables to be unloaded, while configuration files specify parameters such as buffer sizes, data set names, and the number of parallel tasks.

InfoUnload leverages DB2's security mechanisms, supporting authentication methods like RACF, ACF2, and Top Secret. It uses role-based access control (RBAC) for managing user permissions. Monitoring is typically performed using standard z/OS monitoring tools and DB2 performance monitors.
Competing products include IBM's UNLOAD utility and BMC's UNLOAD PLUS. InfoUnload distinguishes itself through its focus on performance and efficient resource utilization, often providing faster unloading speeds than standard DB2 utilities. It interacts directly with DB2 databases on z/OS, using standard DB2 storage mechanisms for reading table data.
