ACS Groups
  • Ability to close the Description area (right column) on the main ACS interface 
  • Customize the description for the 'Hardware Management Interface ' values that can be defined for each system configured. 
  • Run SQL Scripts now supports Tabs. Each connection (window) now has the ability to have many tabs where you can have separate SQL Scripts open and being edited. This provides a very nice way to easily work on many files. You can even drag and drop a folder with select SQL files into a new Run SQL Scripts window, and a new tab for each file is opened. 
ACS Run SQL Scripts Tabs

Application Development

General App Dev Updates 
  • The Call (CALL) and Call Bound Procedure (CALLPRC) commands now allow expressions to be passed as parameters and allow you to specify type and length for each parameter.
  • New ILE C/C++ built-in functions for atomic memory access are added in this release. In a program with multiple threads, you can use these functions to atomically and safely modify data in one thread without interference from another thread.
  • Call Services Program Procedure API (QARUCLSP) raises the number of parameters up to 248.  
  • OPTION(*EVENTF) was added to selected program commands  
Integrated File System

Integrated File System Exit Points

Two new exit points are supplied in this release: QIBM_QP0L_OBJ_CLOSE and QIBM_QP0L_OBJ_OPEN. A new file system attribute, 'Run exit program', controls whether the exit programs registered to these exit points will run when a file system object is opened or closed. An exit program can perform application-specific processing when the object is opened or closed, such as verification, conversion, or removal of temporary objects.  This support is enabled for the root, QOpenSys, user-defined, and QDLS file systems.  More information can be found in the IBM i Documentation for these exit points:

Integrated Web Services Server - Rest API Engine
The Rest API engine integrated in to the operating system has significantly improved its access logging capabilities.  These new capabilities now allow users to have very detailed views of who, what, when, and where when it come to the usage of Rest APIs for IBM i.  The following provide details on how to configure the IWS support for these new features:
