PowerExchange adds support for Db2 Huffman compression of image-copy sources for bulk data movement.
IBM introduced Huffman compression hardware support on z14 mainframes for compressed table spaces in Db2 Version 12 at function level 504. Db2 Huffman compression can help reduce disk space and I/O costs. PowerExchange 10.4.1 includes support for Huffman-compressed image copies through hardware and software on pre-z14 systems.
