My ideas: IBM Java SDK for z/OS

Meaningful Return Codes for Using Semeru in Batch (z/OS)

We use the z/OS Java Batch Launcher (JZOS) for running Java workload in batch. We recognized that we sometimes get low return codes from the JVM also for severe errors. One example is APAR IJ55765 (Java JIT crash to uncaught exception). For us a J...

Support for VSAM Linear Data Sets (LDS) in JZOS / ZFile APIs

Summary Request support for VSAM Linear Data Sets (LDS) within JZOS, particularly through the ZFile API, to enable efficient, high-performance access to unstructured binary data without requiring record-oriented formatting. Current State JZOS and ...

Programmatic API for Dataset Allocation in JZOS

Request the introduction of a structured, programmatic (API-driven) interface for dataset allocation within JZOS, as an alternative to the current BPXWDYN string-based allocation mechanism. The goal is to improve developer productivity, reduce com...

method PlatformAccessControl.checkMyPermission should not require BPX.SERVER access

checkMyPermission should work like RACHECK/RACROUTE does. It should allow a "normal user" to check own permissions without requiring additional permissions like BPX.SERVER. This would also be consistent with the documentation of checkPermission ve...

Add optional parameter to set the DATACLASS for JAVA DUMPs

Would be beneficial to set the DATACLASS to EXTENDED so dumps are eligible for Pervasive Encryption. We understand that we can define the dump dataset mask to an ACS routine but this creates additional overhead in large shops. Ideally, there would...

Support of GCM mode for IBMJCECCA with a key from CKDS

On z/OS we do file encryption with a JAVA framework that must use the IBMJCECCA provider to use a CKDS key. The cipher.update function is not supported in this mode, but it is supported in CBC mode. It is indispensable for encrypting large files F...

Allow RACF digital certificate registration from Java interface

Currently the only way to allow users to self register their personal certificates, from CAC or PIV cards, is to use the ASIS self registration tool provided in SYS1.SAMPLIB(RACINSTL). While this tool works we are running into issue where browsers...

JZOS Fields annotation library

The JZOS field-creation API is somewhat verbose, while Java developers are used to annotation-based serialization librarys (e.g. Jackson, Hibernate). With suitable choices of defaults, an annotation library could with very little annotation burden...

ByteBuffer / Charset interface for JZOS fields

There are a couple more-modern Java APIs that it would be useful to use in JZOS fields. In particular, the fact that the working character set is exposed in the API as a String charset name rather than a java.nio.Charset object imposes some inconv...

Enhanced JZOS Fields factory methods

From experience building WCA4Z, one common point of confusion is how the DatatypeFactory keeps the offset of the generated fields implicit rather than explicit. Another point is the large number of undifferentiated boolean flags to the Field const...
