Introduction

CA Compress is a CA Technologies mainframe software product that transparently compresses and expands VSAM and Physical Sequential data sets, including those under CICS control. It fully supports data sets under the control of IBM's Storage Management Subsystem (SMS). No special procedures are required to compress SMS-controlled data sets.

CA Compress (CA Compress) offers several compression routines. With CA Compress, you can achieve compression of up to 80 percent. In addition, you can create custom compression routines for specific data sets to achieve even greater compression. The product includes a performance enhancement feature which optimizes VSAM data sets to improve elapsed time for sequential and direct access operations.

Data compression with CA Compress offers numerous advantages to IS organizations:

Significantly reduced DASD requirements.
Reduced backup and restore times.
Improved data security.
Easy to use interactive ISPF interface.
Choice of maximum compression or minimum CPU overhead.
Transparency to application programs.
