Course Overview
The IBM IMS Database Recovery Control (DBRC) (CM20G) course is an advanced training program designed for IMS system programmers, Database Administrators (DBA), and technical support professionals responsible for the installation, customization, administration, and maintenance of DBRC within an IMS environment. This comprehensive course covers critical topics such as DBRC implementation, database registration, log information recording, data sharing, subsystem authorization, and RECON maintenance and recovery. As organizations continue to rely on IBM IMS for high-volume transaction processing, expertise in DBRC is essential for ensuring data integrity and system availability. With over 70% of Fortune 500 companies utilizing IBM IMS in their core operations, professionals skilled in DBRC are in high demand across finance, insurance, and telecommunications sectors.
Students engage with key IBM technologies including IMS DBRC, RECON (REcovery CONtrol), GENJCL (GENerate JCL), and utilities for database management and recovery. The hands-on lab component allows participants to configure and manage DBRC subsystems, register full-function, Fast Path, and HALDB databases, define recovery groups, and simulate real-world disaster recovery scenarios using IBM-supplied skeletal JCL. These labs are conducted in a z/OS mainframe environment, providing direct experience with the tools and interfaces used in enterprise data centers. A key project involves implementing a complete DBRC solution across a simulated multi-system IMS environment, including setting up data sharing, securing subsystem access, and performing recovery operations to reinforce resilience and operational best practices.
Completion of the IMS Database Recovery Control (DBRC) (CM20G) course prepares learners for IBM’s official certification pathways in IMS administration, a credential recognized across industries for validating deep technical expertise. Certified professionals report an average salary increase of 15-20%, with senior IMS DBAs earning between $95,000 and $130,000 annually. Koenig Solutions enhances this training with Guaranteed-to-Run scheduling and access to official IBM courseware, ensuring learners receive up-to-date, vendor-authorized content.
