Following the tradition of delivering new functions and business value to the IBM i operating system and related products through Technology Refreshes, IBM is announcing IBM i 7.3 TR3. This Technology Refresh provides usability enhancements, new security capabilities, and significant new functions in many of the operating system components and licensed programs. A few of the business benefits that can be realized are described here.

With IBM i 7.3 TR3, Db2 for i continues to focus on new and advanced SQL capabilities and the ability to use SQL to access IBM i operating system details. Further, Db2 for i delivers new features for the creation of data-centric JSON solutions. Finally, Db2 for i delivers new capabilities to allow IBM i history logs and security audit details to be consumable by a security information and event management (SIEM) solution.

IBM i is introducing a new installation method that uses USB Removable Mass Storage technology, making the IBM i installation easier and more convenient. While there are many potential uses, the one that most clients will explore is the ability to download IBM i images from the Entitled Systems Support (ESS) website, copy them to a USB flash drive, do a D-mode IPL on a managed system, and then install LIC, XPF, and any LPP images that fit onto the media.

IBM i integrated web services, both the server and client, have been enhanced to give programmers and administrators more flexibility when leveraging web services on IBM i in a safe and secure manner. The server has been updated to support a multitier solution, and the client code now supports SSL when connecting to a web service.

Open source enhancements have been delivered in several areas, including open source projects, the IBM i open source solutions program offering, the operating system, and system access tools. These new open source functions enhance functionality for application developers, system administrators, and users. It is easier to deploy secure web solutions, use open source languages, port applications, and much more.

Rational Development Studio has updates for the application developer to improve the RPG language as well as invoke code coverage directly from the command line.

Access Client Solutions, the strategic interface for users, system managers, and database engineers looking to access IBM i, continues to be improved to address additional functions as well as updates requested by the ACS user community.

IBM i has been enhanced to work better with IBM PowerVC for cloud capabilities. You can now store an image using a small LUN size, and then later deploy it with a larger size that fits the storage needs. You can also increase the LUN size after it's been deployed to get additional storage capacity. For IBM i PowerVC clients who are using CloudInit, it will be enabled automatically on deployment.

For clients who do not have an HMC, the actions to install an IBM i partition from a backup onto a new load source have been simplified. In particular, the LAN console configuration is now saved as part of a SAVSYS operation and is later accessed during the D-mode IPL, eliminating the time-consuming steps of pulling together the information and configuring the LAN console separately using operator panel functions during the installation process.

Db2 Web Query for i has a new release, version 2.2.1, with numerous new features. Report authoring and advanced data analysis just got easier with additional visualizations that provide more powerful analytics. Report and dashboard navigation is made simpler for users with the introduction of report auto-link, auto-drill down, and dynamic parameterization. Service providers can also leverage the new capability to set the number of user licenses by logical partition.

Db2 Web Query DataMigrator is also refreshed in version 2.2.1. New features include simplified functions for building straightforward but powerful transformations, data flow comments on the developer palette, regular expression support for filtering, and improved scheduling.

The IBM i Technology Updates wiki in developerWorks® contains details of i operating system enhancements. To view technical details for the topics found in this announcement letter, see the IBM i 7.3 TR3 enhancements website.

Included in this Technology Refresh are new functions and features for a variety of components in the base operating system, Db2 for i, licensed programs, and associated other products. This Technology Refresh provides usability enhancements, new security capabilities, and significant new functions in many of the operating system components and licensed programs.

IBM i 7.3 TR3 and associated IBM i licensed programs will be generally available (GA) on October 27, 2017, unless otherwise noted.

Db2 for i enhancements

With IBM i 7.3 TR3, Db2 for i continues to focus on new and advanced SQL capabilities and the ability to use SQL to access IBM i operating system details. Further, Db2 for i delivers new features for the creation of data-centric JSON solutions. Finally, Db2 for i delivers new capabilities to allow IBM i history logs and security audit details to be consumable by a security information and event management (SIEM) solution.

Database application developers have new capabilities for constructing data-centric SQL solutions:

  • JSON publishing functions can be used by the database application developer to build JSON objects from Db2 for i relational data. This standards-based technology enables a database application developer to leverage the query engine to efficiently construct JSON.
  • JSON scalar functions enable the SQL programmer to efficiently process JSON objects. These functions join the existing JSON_TABLE function as techniques to programmatically shred JSON.
  • Stateless pagination in the database becomes easier and more powerful by extending the LIMIT and OFFSET support.

These and other SQL enhancements are described in developerWorks.

Security auditors have a new source of Syslog security details to consume. With a consumable tap of standards-based security details, IBM i clients can take a noteworthy step forward in governance of security.

  • The HISTORY_LOG_INFO table function is extended to include the option of returning IBM i history log details in Syslog format.
  • The DISPLAY_JOURNAL table function is extended to include the option of returning a subset of IBM i audit journal entry types in Syslog format.

In the tradition of recent Technology Refreshes, IBM i services are added, providing useful SQL-based alternatives to IBM i commands and APIs:

  • The ASP_INFO view returns information about auxiliary storage pools (ASPs). Administrators will be able to advance their management of ASP existence, configuration, and storage with this service.
  • The ASP_VARY_INFO view returns one row for each step associated with a vary on or vary off operation for all independent ASP devices. By having this service, administrators can use the SQL Query Engine to compare and contrast vary on performance over time.
  • The JOB_QUEUE_INFO view returns one row for each job message queue. This service adds to the set of work management topics that can be managed by the use of SQL.

These and other IBM i services are described in developerWorks.

These and other enhancements are delivered through Db2 PTF Group SF99703, which will be released on October 27, 2017. See the IBM i Technology Updates wiki on developerWorks to learn more about these and other Db2 for IBM i enhancements.

To see the Db2 for i PTF Group details, go to the Db2 for IBM i 2017 Group PTF Schedule wiki.

Base operating system

New installation process

IBM i is introducing a new way to perform software installations using virtual media that has been copied to a USB 3.0 removable mass storage media (for example, USB 3.0 flash drive) that is attached to an available USB 3.0 adapter. The My Entitled Systems Support website offers a Licensed Internal Code (LIC) media image specially formatted for use with USB 3.0 flash drives. Note that this is in addition to, not in place of, the DVD media image currently available.

See the General IBM i operating system Technology Updates wiki for more details.

Automation for CloudInit

Previously, CloudInit, which is primarily used by PowerVC clients, needed to be enabled before capturing a logical partition. Now a deployed partition on a POWER8 system can automatically enable the IBM i CloudInit component on the deployment of a partition.

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 (ILE programs or service programs) resides on a different IBM i system. This is a key enhancement for companies that want to leverage a multitier 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 on the Technology Updates web page, which may be found on the Integrated Web Services Product page.

IBM i integrated web services client for ILE

The client transport support of the integrated web services client has been enhanced to support SSL when connecting to a proxy server. The new support includes:

  • The ability to use a secure channel (SSL) when connecting to a proxy server.
  • The ability to perform SSL tunneling when connecting to a proxy server over an unsecure channel. In SSL 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. These updates are included in the latest HTTP Group PTF. Details can be found in the Web Services Client for ILE Programming Guide and on the Technology Updates web page, which may be found on the Integrated Web Services Product web page.

IBM i support of the 4767 Cryptographic Co-processor

IBM i now supports the 4767 Cryptographic Co-processor. The 4767, announced earlier this year, is the follow-on adapter to the 4765 Cryptographic Co-processor and includes considerable performance improvements over the predecessor 4765, while maintaining the level of security to which clients are accustomed. The 4767 adapter provides access to updated Common Cryptographic Architecture (CCA) APIs, automatic CPU off-loading of SSL/TLS handshakes, and the most secure physical adapter available for secure cryptographic master key storage.

The CCA libraries have been updated to CCA 5.3 and have added API enhancements, which are also available for use with the previous 4765 adapter. Highlights of these changes for the 4767adapter include new PIN processing APIs, financial services support for DK and Visa Data Secure Platform with point-to-point encryption, improved security, access, and logon control, among other features. For a complete list of these features and changes, see the CCA Basic Services Reference Manual.

The 4767 Cryptographic Co-processor is available via feature EJ32 (without blind-swap cassette) or EJ33 (with blind-swap cassette).

In order to enable the new 4767 adapter or enable CCA 4.4 APIs for the 4765 adapter, clients will need to install IBM i 7.3, PTF SI63186. Additionally, clients will require a minimum release of 7.3 TR1 (MF99201).

  • libjpeg
  • libxml2
  • libxslt
  • libpng
  • libfreetype
  • libpcre

For more information, see the Open Source Technology Tools wiki page.

Ability to customize user's SSH shell

The shell used for SSH connections can now be configured on a per-user basis. This functionality is exposed through the SET_PASE_SHELL_INFO procedure. While the shell can be set differently for different users, a system global default can also be set. Many SSH users may prefer the Bash shell /QOpenSys/QIBM/ProdData/OPS/tools/bin/bash, which is delivered in 5733-OPS option 7.

The USER_INFO catalog has also been enhanced with the new column PASE_SHELL_PATH, which enables you to query or display the SSH shell configuration for a user.

For more information, see the Procedure and Catalog page.

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

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

Open source PASE database driver

IBM has created a new database driver designed to enable easier Db2 integration in an asynchronous model. Over time, this new enhanced driver should be used to replace the previous XML Service technology and provide another avenue for integrating with ILE programs, service programs, CL commands, and more. It provides seamless replacement of the previous CLI APIs, 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. For the latest status and information (or to contribute), see the project web page.

Other open source contributions

IBM has contributed to other open source projects that will benefit IBM i open source users. Some examples include:

  • Mama: Apache FastCGI module to manage stand-alone web server applications like Node.js.
  • Borgi: A chroot safe 'system' utility with user-expandable helper scripts for ILE Makefiles (crtrpgmod, crtpgm, and so on).
  • Db2util: A command-line utility similar to STRSQL.
  • Nodejs: Best practice node examples for Db2 pooling, toolkit calls using REST, and more.
  • Python-for-IBM-i-examples: Small, containable examples of integrating Python with IBM i. There is a simple active jobs dashboard, a tool to convert SQL or Db2 tables to Excel format, and a utility that provides netstat-like functions, making it possible to see the status of active connections on the system.

Details on leveraging code coverage from the command line can be found on the developerWorks Modernization page.

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 first time. Code quality has been a recent theme of additions to Rational Developer for i, 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.

This has been available through RDi, but now the analysis can be done on the IBM i from any command-line invocation, and RDi is required only 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.

For additional updates, see the IBM Fix list for Rational Developer for i website.

Rational Developer for i, V9.6 will be generally available (GA) on November 21, 2017.

Db2 Web Query for i, V2.2.1

Db2 Web Query for i, Version 2.2.1 adds a significant number of new features to address user requests and bring new industry features for reporting and analytics to IBM i clients.

Letting users navigate from one report to other related reports just got simpler with the new auto-link, auto-drill down, and dynamic parameter features. Users can now navigate across multiple reports, drill down on specific data elements or detail reports, or even decide which filtering is important in the report. All of this is possible without the author of the report defining and adding it ahead of time.

Data visualization is a hot topic in today's industry and Db2 Web Query V2.2.1 delivers new, powerful data visualization for the data scientist. This technology helps users to visualize patterns in the data and follow through on discoveries for further insights.

Geographical maps, introduced in a previous version, are used to plot data points on a map in a dashboard or stand-alone view. This geographical data analysis has been further enhanced with additional Esri enrichment to bring additional information to maps quickly and easily. Several additional layers are built into Db2 Web Query, and other layers are available through Esri (for an additional charge). This support allows the viewing of demographic data or the adding of layers such as bus or train routes for further geo analysis. Tooltips are also now supported for maps.

One of the key benefits of the Db2 Web Query product set is its ability to leverage an industry best practice of providing a metadata layer. With version 2.2.1, working with metadata is even easier with enhancements to the browser-based Synonym Editor. It is possible to quickly define joins, hierarchical data relationships, and virtual fields to simplify and standardize data for report authors and users.

From a product management perspective, Web Query administrators gain additional capabilities to manage resources through a full console interface. User licensing can now be controlled down to the partition level.

EZ-Install, IBM's simplified installation and sample reports package, is enhanced to support version 2.2.1. It also includes additional sample reports. The EZ-Install package can also be used to upgrade existing installations of Db2 Web Query. Email to learn more about EZ-Install.

Db2 Web Query, V2.2.1 will be generally available (GA) on December 8, 2017.

Db2 Web Query DataMigrator, V2.2.1

Db2 Web Query DataMigrator, Version 2.2.1, adds several new functions, along with the simplification of existing functions, to make building transformations easier than ever. Additionally, DataMigrator now supports regular expressions for filtering, providing capability well beyond simple wildcard searches.

The DataMigrator developer palette for creating flows has enhanced navigation assistance that allows the adding of comments to each step in the flow. This makes it easier to understand flows and share them with others.

Scheduling of flows just got easier as DataMigrator detects potential overlaps of flows and minimizes collisions when multiple schedules are active at the same time.

IBM Cloud Storage Solutions for i, V1.2

IT organizations are increasingly using public and private cloud services to share files, back up data, and archive data. The first release of Cloud Storage Solutions for i, V1.1, provided an API that integrated with IBM Backup, Recovery and Media Services (BRMS). Version 1.2 introduces a new optional feature that provides compression and encryption. For details and ordering information, see Software Announcement ZP17-0610, dated October 3, 2017. .

Monitoring and understanding the state of the IT ecosystem, including IBM i, has changed. Nagios is an open source industry standard tool for understanding all the components in an IT network. IBM i is now a supported system within the Nagios infrastructure. IBM i has written a number of plug-ins to enable many key IBM i metrics to be monitored and graphed, and to provide notification based on thresholds.

Details on how to obtain these plug-ins, instructions for installing these into Nagios, and what metrics are supported can be found on the developerWorks wiki.


IBM MQ Fix Pack and IBM Managed File Transfer (MTF) V8.0 for IBM i have been delivered. For more details, see the IBM MQ and IBM MFT V8.0 for IBM i Fix Pack web page.


Increase of virtual LUN size after initial allocation

External storage systems have the capability to increase a LUN size after its initial allocation. In the past, IBM i has ignored any increase in a LUN's size on an external storage system. Additional LUNs needed to be added to increase the capacity of a logical partition. With IBM i 7.3 TR3, IBM i will recognize that an increase has occurred and, after an IPL, will allow the LUN to be used at its newly increased size.

This capability is also useful for cloud functions, such as deploying a new partition with a larger LUN size than the default allocation in the saved template. Specifically, IBM PowerVC deployments of new IBM i partitions will now be able to adjust LUN sizes to meet the storage needs of the new deployment.

Increase in maximum number of LUNs per Fibre Channel IOA

Clients have been growing their configurations at a pace that has caused them to hit the limit on the number of LUNs they can create for each Fibre Channel port. The limit of 64 has now been increased to 127 for both NPIV and native-attached 16 Gb Fibre Channel configurations.

IBM i system backup saves LAN console configuration as part of the LIC data

IBM i 7.3 TR3 includes recently released PTFs that eliminate steps when installing IBM i onto a new load source from a SAVSYS. The LAN console configuration is now automatically saved to a new LIC LID during a SAVSYS operation. This enables the LAN console server to start during the D-mode IPL and be ready for the IBM i Access Client Solutions (ACS) connection. There is no longer a need to pull together the LAN console parameters and configure it separately if the same LAN console is being used for the new load source installation. No user actions are required to take advantage of this new support. The system will automatically attempt to use the previous configuration during a D-mode IPL that uses a backup created from a partition that had IBM i 7.3 TR3, or later, code level.

Automatic sorting of volumes in optical container media

The volumes on an optical container media used for installation are now automatically sorted, so there is no longer a need to create a VOLUME_LIST file or to run VFYIMGCLG to first get the volumes sorted in proper order for installation. The operating system will also verify that there is only one bootable media in the catalog; any subsequent bootable volumes will be dropped from the loaded list and an LIC log will be generated.

Additional new hardware functions

IBM i 7.3 TR3 also includes this hardware-related support:

  • Maximum disk size has increased to 4 TB for 4160 byte sector disks.
  • USB flash drives with capacity greater than 32 TB are now allowed.
  • Improved debug capabilities are provided for storage IOA failures.
  • Some configurations that include IBM DS8000® storage systems may get a performance benefit due to changes in the implementation of low-level I/O architecture.
  • Support is provided for IBM TS1155 Tape Drive Model 55F.
  • Support is provided for IBM TS4300 Tape Library.

In addition, the following recent announcements for the Hardware Management Console provide IBM i clients with additional options for managing their Power Systems, both virtually and as a closed appliance:

  • IBM Power Systems Hardware Management Console virtual appliance for POWER®-based systems offers increased deployment flexibility. For more information, see Software Announcement ZP17-0250, dated August 8, 2017.

Top rule
Product positioning
Bottom rule

IBM i 7.3 is the latest version of the IBM i operating environment. It runs on a Power Systems server and offers a highly scalable and virus-resistant architecture with a proven reputation for exceptional business resiliency. Companies that run applications on i running on a Power server are able to focus on innovation and delivering new value to their business, not on managing their data center operations.

IBM i delivers a fully integrated and trusted combination of relational database, security, web services, networking, and storage management capabilities that are required to run business applications. For example, IBM installs and integrates the SQL standards-based Db2 database for i with advanced database management utilities, plus additional middleware components such as multiple file system options, directory capability, an HTTP web server that is powered by Apache, a web application server, and a web services environment.

IBM develops, fully tests, and preloads these core middleware components of i together. The preintegration and testing of i is a key factor in enabling companies to realize lower operations costs by deploying applications faster and maintaining them with less staff.

Virtualization and workload management are also built into the IBM i operating environment to enable businesses to consolidate and run multiple applications and components together on the same system, helping to drive up system usage and delivering a better return on IT investments. This broad and highly stable database and middleware foundation is ideal for efficiently deploying business processing applications.

Architecture for simplicity, stability, and security

Another important advantage for i is the underlying architecture of the operating system, which enables simplicity, stability, and security. These are not add-on features, but inherent aspects of the operating system. Here are a few examples:


The relational database in i is an integrated component that is built on a set of integrated storage management capabilities unique to i and its predecessors. This storage management is based on the single-level storage architecture that treats all of the storage managed by i as one long stream of memory that encompasses the system memory and the storage on disks. This architecture makes it critical for the operating system to decide where to store any given piece of data, which removes the user from having to manage data placement. This method makes management of storage and the database objects contained in that storage significantly simpler.


IBM i architecturally separates the address spaces of user applications and the operating system, so it is difficult for poorly written or malicious software to intrude upon the underlying operating system support. This is one of several attributes that can help keep i running for days, weeks, and months without unexpected restarting of the operating system.

Several architectural attributes of i have contributed to the stability of the system over the years. First, applications compiled on i are compiled to a set of intermediate code instructions defined as the Technology Independent Machine Interface (TIMI). This enables i to fundamentally change the implementation of underlying hardware, firmware, and virtualization features, without requiring rewriting, changing, or even recompiling the applications written by users. This sort of forward compatibility can be a tremendous business advantage, and it enables the movement of software developed and compiled several years to even decades before to run on later generations of the i operating system.


IBM i and its predecessors have an object-based architecture. Each entity on the system is an object, which has a set of prescribed operations that can be performed on it and connections from the object to those other objects that are allowed to perform various operations. An object that does not have a legal edit operation cannot be edited. It cannot be renamed to another kind of object. If the object does have an edit operation, known as change for most objects, it only has a defined set of attributes that can be edited, and then only by users who have authority to do that editing.

Objects can easily be hidden from other users by use of the library list objects, and security enhanced by the object-based security associated with all objects. And users who all have a similar role on the system can be grouped for role-based security, again as part of the base architecture of the system. While the i operating system supports Java, PHP, web services, and other open source programming methods, the underlying architecture offers a level of integration, stability, simplicity, and security that makes it significantly different from comparable operating systems. These aspects can deliver excellent business value to its users.

Statement of good security practices
Bottom rule

IT system security involves protecting systems and information through intrusion prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a regulatory compliant, comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective.

Important: IBM does not warrant that any systems, products, or services are immune from, or will make your enterprise immune from, the malicious or illegal conduct of any party.
