Add REFVVDS(volser) parm to DEF CLUSTER with RECATALOG

We have ZFS datasets in the SYSRES (&SYSR2, in our case).We're upgrading z/OS and we need to catalog new ZFSs indirectly using &SYSR2 - we're not using SSA.When we try to use a DEF CLUSTER with RECATALOG the job fails as the VVDS in the cu...

Append dataset API

Add an API to append to a dataset. This is already a feature in batch programs. At present, to append the entire dataset has to be downloaded, appended on the device, then overwritten. This is substantial traffic for something like logging.

ERASE ON SCRATCH delegated to the DS8000 CECs

When a dataset is marked for erasure upon deletion ("erase on scratch"), the operation consumes zSeries CPU cycles. This proposal recommends offloading the CPU cycles required to erase datasets flagged by RACF ERASE to the DS8000 CECs, in a manner...

Add Functionality to access EzNOSQL JSON Documents thru TCP/IP from distributed systems (outside z/OS systems)

EzNOSQL would be a nice and useful product, when JSON documents on z/OS would be accessable from "outside" z/OS out of the box i.e. thru a JDBC driver and /or open systems python libraries.

Add a command to know the calculated value for ZHPF buffer when ZHPFOPTS has SYSTEM parameter

For ZHPFOPTS if SYSTEM is specified, the maximum data transfer size for zHPF I/O requests is determined by the system based on the maximum data transfer size supported by the device and its online CHPIDs. So if something changed on CHPID, Switch ,...

ISHELL and OMVS must use same profile. If RACF says that zsh is the shell both OMVS and ISHELL must use ~/.zprofile to setup path ect and if /bin/sh is specified ~/.profile is use both places.

Make sure that the shell and setup from RACF is used, remove confuseion over $path and other environment variables.
