ADRDSSU RESTORE to allow target system SMS attributes

While running z/OSMF PSI to install z/OSv2r5, Job IZUD05UZ invokes GIMUNZIP which calls ADRDSSU to RESTORE the zFS data set. Unfortunately the target data set always get the DATACLAS value from the source data set. Thus the target zFS gets the DAT...

DFDSS to define new target GDG base and use relative generations for target GDS's.

DFDSS has the ability to process input Generation Data Sets via relative generation numbers, but cannot create new target generations using the relative generation (+n). It also cannot define target GDG's as part of a COPY or RESTORE operation.

FCIC JOB takes long time with msg IGD17291I.

When the client tries to take DB2 image copy by a use of FlashCopy, it takes very long time with msg IGD17291I.This IGD1729I message means, "when the initial allocation can not be satisfied on one volume, it will try to add additional volumes to t...

Allow DSS to produce easily transportable dumps

Currently DFDSS does not produce backup or dump output in a form that can be easily transmitted across the network with normal basic FTP clients (e.g. Linux, Windows) and servers. The dump normally has to be further processed by TRSMAIN or XMIT be...

Optimized ADRDSSU CPU usage for uncompressed Striped Datasets backup

WHEN CALLING ADRDSSU TO DUMP A non-compressed SEQUENTIAL DATASET TO TAPE THE AMOUNT OF CPU FOR PROCESSING A 16 STRIPE DATASET WITH OPT(4) IS APPROXIMATELY 500-700% OF THE CPU USED TO DUMP THE SAME DATA FROM A NON-STRIPED OR SINGLE STRIPED DATASET ...

Increase or remove DFSMSdss 255 SYSIN statement limit

DFSMSdss has a limit of 255 SYSIN statements per execution. This limits to ~200 the number of datasets in any one execution of COPY or RESTORE with individual RENAMEU statements, even when using DATASET(FILTERDD(name)).
