Lightning Reclaim

The architecture of Lightning Reclaim likely comprised several key components. The Database Analysis Module would have scanned the IMS DEDB database to identify fragmented or unused space. The Space Identification Engine would have analyzed the database structure to determine the optimal reorganization strategy.

The Data Reorganization Engine would have performed the actual data movement and space reclamation. These components would have interacted with IMS through standard interfaces, such as the IMS Database Manager. The product likely used JCL for batch job submission, which was the primary interface for initiating reclaim operations.

Configuration parameters would have included dataset specifications, reorganization thresholds, and performance tuning options. Security would have been managed through z/OS security features, such as RACF or similar security products. The product's functionality is now integrated into BMC AMI Ops Monitor for IMS and BMC AMI Reorg for IMS, which offer similar capabilities for online freespace reclamation and database optimization.
