CA Compress™ Data Compression for IMS is designed to minimize the direct access storage device (DASD) space requirements for IMS™ databases and compress files with minimal disruption, reduce your costs and simplify DASD management. This IMS database management solution can also improve efficiency by performing compression simulation for analysis purposes before actually compressing an IMS database—a process that can achieve compression yields as high as 70 to 80 percent.
Designed to circumvent standard database storage limitations, CA Compress Data Compression for IMS helps free valuable space while giving you full control over which segments of a database to compress and how much compression to implement on a segment. In addition to offering a full complement of compression tools, this DASD storage solution helps you plan for future use with IMS for z/OS forecasting, simulation and analysis functions. Before and after compression, it enables you to maintain full IMS data integrity with byte comparison tools and full data recoverability.
