Provide common APIs in support of PDSE Member Generations - Part 2

See https://ibm-z-hardware-and-operating-systems.ideas.ibm.com/ideas/ZOS-I-3783 for part 1. Given that PDSE member generations are supported by some, and growing, IBM elements, it only seems reasonable to make it easy. Thus I'm rating this IDEA as...

RACF control to allow or disallow copying of data from an encrypted dataset to an unencrypted dataset

Today if a person has access to a key label there are no controls in place to limit their ability to copy an encrypted dataset to a dataset with no DFP segment in it's RACF dataset profile. When this is the case the dataset is unencrypted when wri...

BUFNO calculation for Extended format sequential datasets

BUFNO are calculated according to the following formula: n—Extended format but not compressed format and not LBI (n = 2 × blocks per track × number of stripes)1—Compressed format data set, PDSE, SYSIN, SYSOUT, SUBSYS, UNIX files2—Block size > =...

Provide API's for basic PDSE Access

Currently the internals of a PDSE (version 1 or 2) are hidden from the user who doesn't have a NDA and access to FAMS. Please expose to the user/ISV community some of that information. Such as: Current MAXGEN value for the PDSE Ability to dynamica...

BLDL to PDSE need to return RC=08 at I/O error instead of ABEND212

PDSE data sets are used in IMS Online environment and issue BLDL, FINE, READ, CHECK macros.DCB specify SYNAD exit and ABEND Exit. But BLDL to PDSE issues ABEND212 with DFS909I 212-00 instead of RC=08 at I/O error. When we used standard PDS, it ret...

Provide common APIs in support of PDSE Member Generations

We know member generations are useful but to access them requires a lot of work, especially from the open environment. By providing a set of common APIs current, i.e. REXX, and new, i.e.Perl, python, etc. will be able to easily work with member ge...

Enhance ISITMGD to provide number of gens for PDSE V2 with member generations

The ISITMGD (IS IT ManaGeD) macro provides an indicator for PDSE V1 or V2, and an indicator if the PDSE V2 supports member generations, but does not provide the number of member generations. This interface should be enhanced to provide the number ...
