RELATED IDEAS

The user must have the ability to keep a dataset in zEDC compressed format during a copy or a transfer of the dataset.

I would like to have a way to request access method to avoid decompression of a zedc compressed dataset when using it, for example via a jcl option. This would avoid unnecessary compression - decompression when dataset are accessed by product doing copy or transfer of a zedc dataset that must stay in zedc format. It will allow to use standard product like iebgener, NFTP, ... to be used with zedc datasets saving cpu and elapsed time for unnecessary works.

This is possible now if datasets are dumped with dfdss but this request to add a dfdss step.

    Since zEDC compressed format data sets are written as full track physical blocks, IBM is investigating providing limited support for large block interface (LBI) processing through BSAM for DASD data sets. If possible, then BSAM may also allow programs to read/write physical blocks avoiding decompression/compression through a special interface.
