CA Compress Data Compression

CA Compress Data Compression is a z/OS-based solution designed to automatically compress and decompress datasets, providing transparent operation to applications. The architecture centers around integrating directly with z/OS dataset management facilities. The core components include the compression engine, which utilizes specific algorithms to reduce the physical size of datasets, and the decompression engine, which restores the original data when accessed.

These components operate within the z/OS LPAR environment. The system intercepts I/O requests to datasets and dynamically compresses or decompresses data as needed. This process is managed by z/OS system services.

, RACF) for authentication and authorization. Key architectural considerations include CPU overhead, I/O performance, and the selection of appropriate compression algorithms. Alternatives include other z/OS compression utilities.

The product requires careful configuration and monitoring to ensure optimal performance and minimal impact on other z/OS workloads. The configuration parameters are managed through z/OS system parameters and control datasets.
