CA Spaceman

The architecture of CA Spaceman is centered around several key components designed to optimize ADABAS file performance and storage. The main components include the Space Analyzer, Reorganization utility, and Compression utility. The Space Analyzer provides detailed reports on space usage and fragmentation, utilizing ADABAS system calls to gather information about the database files.

The Reorganization utility rearranges the physical structure of ADABAS files to eliminate fragmentation and improve data access. This component uses ADABAS system calls to move data blocks to contiguous locations, optimizing the file structure. The Compression utility reduces the storage footprint by removing unused space.

The communication between these components is facilitated through JCL or a command-line interface, which allows users to execute commands such as ANALYZE, REORG, and COMPRESS. Configuration files are used to define parameters for these operations, including ADABAS file numbers, thresholds for space utilization, and compression settings. CA Spaceman operates within the z/OS and zVSE/VSEn environments, leveraging the underlying operating system's security features for access control and authentication.

The utility does not use external databases or storage mechanisms beyond the ADABAS files it manages. Network requirements are minimal, as the operations are performed locally on the mainframe.
