DEFLATE compression

HULFT

10.2.0

A new compression preference is added that supports a compression algorithm called DEFLATE.

You can use DEFLATE compression to reduce consumption of network bandwidth and dramatically reduce transfer time when transferring large-capacity files.

zOS compresses data using the DEFLATE compressed data format and zEnterprise Data Compression (zEDC).

Therefore, compared to traditional software based compression services, the CPU cost is reduced and the likelihood of reducing the elapsed time is increased.

 

This compression type can be used for all transfer types (“TEXT”, “BINARY”, “FORMAT”, and “MULTIFORMAT”).

Select "3" (DEFLATE) for the Compression Preference in the Send Management Information.

The compression level of DEFLATE Compression is "Standard."
