System Management  & Access

IBM i Access Client Solutions

IBM i Access Client Solutions (ACS) continues its path for being the IBM i tool of choice for administrators, programmers or database engineers. In this TR, ACS has addressed the needs and concerns of the IBM i user community, providing many  requested updates and enhancements.

General updates

  • Option to disable end users from accepting "trusted" signers
  • Option to enable SSL by default
  • Enable "Check for updates" from command line
  • New SSH client emulator. If an SSH client is already installed on the PC device, ACS will launch the installed client providing ready access to the open source work on IBM i.

5250 Emulator

  • Screen History has been enhanced to now allow an unlimited number of screens to be collected and those screens can now be archived. This support allows a user to track each screen that is displayed and save it for a number of purposes, such as audit, problem recreation, capture screens for documentation and more.

Application Development 

IBM i Integrated Web Services Server
Integrated web services now supports a deployment topology where the integrated web service server is on one IBM i system and the web service implementation code (i.e. ILE programs and/or service programs) resides on a different IBM i system.  This is a key enhancement for companies that wish to leverage a multi-tier network providing the ability to have multiple layers of security. 

To get the updates, it will be necessary to load the latest HTTP Group PTF.

Details can be found in the Integrated Web Services Server Administration and Programming Guide and the Technology Updates web page, which may be found on the Integrated Web Services Product page:

IBM i Integrated Web Services Client
The client transport support of the integrated web services client has been enhanced to support TLS when connecting to a proxy server. The new support includes:
-- The ability to use a secure channel (TLS) when connecting to a proxy server. 
-- The ability to perform TLS tunneling when connecting to a proxy server over an unsecure channel. In TLS tunneling, encrypted data is passed through the proxy server unaltered. This will happen automatically if the web service endpoint uses the 'https' protocol.

In addition, the client transport has been enhanced to allow the toleration of validation failures due to expired certificate or certificate not in key store, which are referred to as soft validation failures.            

Details can be found in the Web Services Client for ILE Programming Guide and the Technology Updates web page, which may be found on the Integrated Web Services Product page:


Rational Development Studio for i
Rational Development Studio for i is providing enhancements to the key languages extending developer capabilities and increasing productivity


The RPG IV language continues to be enhanced with significant new function. Available in March 2017:

  • Code nested data structures directly in free format RPG
  • New built-in functions %MAX and %MIN  to return the maximum or minimum of the operands
  • ALIGN(*FULL) to define the length of a data structure as a multiple of its alignment

Available with PTFs delivered later in 2017:

  • New built-in function %PROC to return the name of the current procedure
  • Allow fully-qualified names in more places such as %ELEM and the DEALLOC opcode

For more information about the features, visit RPG Cafe.

Code Coverage

Initially delivered only in the Rational Developer for i desktop tools, today the code coverage engine is now being delivered as part of the Rational Development Studio, callable only from the command line.  This new support will allow code coverage to be a part of the build process in order to get solid measurement of the effectiveness of tests being executed.

Details on leveraging code coverage from the command line can be found on the Modernization page: Application modernization


Rational Developer for i

Rational Developer for i V9.6 has been updated to continue to provide enhancements to help IBM i application developers better react to the needs of their business, while writing higher quality code the fist time. Code quality has been a recent theme of additions to RDi and this release is no exception. The following key features are part of this new release:

  • Rational Developer for i 9.6 is now compatible with Eclipse 4.6. This brings new base functionality and additionally allows better integration with other modern application development tools.
  • Error reporting has been enhanced to use annotations that will highlight the columns within the line that have caused compile errors.  This location information will be maintained even as lines are added and deleted from the source.   As the cursor hovers over an error, the message will appear along with a link to second-level help.  
  • Hovering over variables will now show the containing data structure or external file and record as well as any other contributors to the definition of this field and allows a hyperlink to them. 
  • The hovers have also been enhanced to show the associated documentation for the given RPG declaration, encouraging better comments as they are even more useful with greater visibility.
  • Any unused declarations can now optionally be flagged within the source.  
  • Pressing the enter key within free form RPG will now intelligently split the line and position the cursor.  
  • Building of i Projects can now be invoked with a shortcut and conveniently allows the setting of IBM i connections and libraries for all the selected i Projects in one action.  
  • RDi also ships with the current version of Access Client Solutions ( and the Java Toolbox (9.3).  
  • RDi has been updated to support the syntax for the very latest updates to the RPG language
  • Code coverage has been updated to now support headless code coverage. Quality assurance has received a big boost with the ability to analyze exactly which lines or procedures have been executed.  This has been available through Rational Developer for i (RDi), but now the analysis can be done on the IBM i from any command line invocation and RDi is only required to view the results.  This will allow code coverage to be a part of the build process in order to get solid measurement of the effectiveness of tests being executed.

Rational Developer for i, V9.6 is Generally Available (GA) on November 21, 2017.

Ability to customize user’s SSH shell

SSH Terminal integration with IBM i Access Client Solutions (ACS)

SSH has become an important tool for accessing the IBM i. If you already have an SSH client installed on your device, ACS will detect it. With a single click, it will open an SSH terminal emulator to your system.

Open Source PASE database driver

In an open source effort, IBM has created a new database driver designed to allow for easier Db2 integration in an asynchronous model. It also aims to replace previous XMLService technology and provide another avenue for integrating with ILE programs, service programs, CL commands, and more. It provides seamless replacement of the previous CLI API’s, while adding superior debug capability, UTF-16 support, and more. The project is expected to be in a stable state before the end of 2017.
