IBM® i 7.2 Technology Refresh 2 (IBM i 7.2 TR2) and IBM i 7.1 Technology Refresh 10 (IBM i 7.1 TR10) deliver new features and capabilities for small, midsized, and large companies:
IBM i integrates a trusted combination of relational database, security, web services, networking, and storage management capabilities. It delivers a broad and highly stable database and middleware foundation for efficiently deploying business applications.
With IBM i 7.2 TR2 and IBM i 7.1 TR10, DB2 for i, which is incorporated into the operating system, continues to focus on new and advanced SQL capabilities, database engineer productivity, SQL Query Engine (SQE) performance, and the ability to use SQL to access IBM i operating system detail. By moving up to the latest DB2 PTF group, clients will have a database that provides significant new capabilities for a wide range of users.
IBM continues to deliver new SQL-based services in IBM i 7.2 TR2 and 7.1 TR10. Several new IBM i services are provided, extending the ability to use SQL to efficiently access, transform, order, and subset IBM i operating system details.
Recent networking enhancements to SNMP for IBM i 7.2 and 7.1 allow application and firewall configuration simplification. SNMP will now send responses via UDP port 161 instead of a random ephemeral port, simplifying firewall configuration. SNMP also now supports GetBulk requests, which provide an easier method for an application to retrieve a large amount of data. The ability to configure storage pool and disk unit block sizes will enable an SNMP manager to calculate an accurate size for large storage pools and disk units.
IBM i continues to enhance the open source ecosystems on IBM i. The Open Source LPO 5733-OPS is enhanced to include support for Python (Option 2) and other improvements for the Node.js support provided in Option 1 for IBM i 7.2 TR2 and i 7.1 TR10.
The recently released REST based support provided in the Integrated Web Services Server support is further improved to support returning user-defined media types and improved processing for the output data.
The IBM Developer Kit for Java for both IBM i 7.1 and 7.2 (5760-JV1 and 5770-JV1) has been enhanced to support Java 8.
IBM i Access Client Solutions, the strategic interface for accessing an IBM i system, has been enhanced to significantly improve the 5250 emulator experience and includes many new features.
This mobile capability, shipped with the IBM i Access for Web product (5770-XH2), is now generally available. Many new mobile-centric features have been included as well as Secure Telnet.
The Application Runtime Expert interface (5733-ARE) has been enhanced to provide the ability to easily distribute PTFs across an IBM i enterprise.
IBM i BRMS delivers periodic sets of enhancements through its PTF group. The most recent new functions extend its ease of use to validate proper network setup, allow centralized media movement, and allow saving of "Q" user libraries in an IASP.
Power Systems with POWER8 technology have additional configuration options, including the support to attach the PCIe Gen3 I/O expansion drawer to selected models of the Power S814 and S824 systems, add additional PCIe Gen3 I/O expansion drawers to the Power E870 and E880 systems, and add additional System Node drawers to the Power E880 Enterprise systems. These options allow even more workloads to be consolidated onto the existing Power Systems with POWER8 technology.
The breadth of I/O options has also been increased with native, native SRIOV, and VIOS support of a new 10Gb Ethernet card. In addition, for IBM i 7.2 TR 2, IBM i supports native and VIOS NPIV attachment to the powerful Flash Systems 900, which is leading edge for high-speed disk storage. These announcements deliver support for the latest technologies that complement the growing workload needs on the Power Systems with POWER8 technology to meet the demands for higher capacity and smaller footprint than were previously possible.
Configuring IBM i with tape libraries and stand-alone tape drives in a SAN configuration that has redundant paths has been complex. With IBM i 7.2 TR 2, both native and VIOS NPIV tape configurations with up to eight redundant paths may be configured, and a preferred path may be specified.
Some types of SAS adapter and disk errors and concurrent maintenance operations in SAS dual adapter configurations have resulted in slower performance on busy systems while automatic error recovery is occurring. IBM i 7.2 TR 2 and IBM i 7.1 TR 10 drastically reduce the recovery time for some of those scenarios.
For additional information, refer to the IBM i Technology Updates wiki, located in developerWorks®
IBM i 7.2 TR2 and IBM i 7.1 TR10 are supported on IBM Power Systems servers with POWER8 processors; IBM Power Systems servers and blades and IBM Flex systems with POWER7® or POWER7+ processors; IBM Power Systems servers and blades with IBM POWER6® or POWER6+ processors; and IBM System i® servers with POWER6 processors.

IBM i 7.1
IBM i 7.2
For the latest information see the Java page on the IBM i zone of developerWorks
Sending responses via Port 161
In the past, IBM i would receive SNMP requests via UDP port 161 and then send a response via a random ephemeral port. This made it difficult to configure firewalls and still allow SNMP traffic to flow between an IBM i SNMP agent and an SNMP-based system or network management application running remotely. The SNMP agent has been changed so that responses to SNMP requests will now be sent via UDP port 161. Traps that originate on an IBM i partition will now also be sent via port 161.
Configuring storage pool and disk unit block sizes
As system storage sizes, with regard to both storage pools and individual disk units, have increased, the limits of the original SNMP design have been reached and sometimes exceeded. The size that SNMP returns for an 8 TB storage pool on an IBM i partition could show up as a negative number in some system management application, or it could be flagged as invalid. The latest enhancements to SNMP now allow the configuration of large block sizes that are used for returning storage size information for both storage pools and disk units. Configuring a larger block size with the Change SNMP Attributes (CHGSNMPA) command will now eliminate negative storage size values and prevent disk units being flagged by system management applications.
SNMP GetBulk request
Simple Network Management Protocol (SNMP) provides a system or network management application with the ability to gather information about network devices and to monitor them. To accomplish this, SNMP defines a set of operations for retrieving and setting data, as well as monitoring for conditions being reported by the devices. One of these operations, GetBulk, provides an application with the ability to easily retrieve a large amount of data with a single request. This can be particularly useful when retrieving information from one of the standard SNMP tables.

These options allow even more workloads to be consolidated onto the existing Power Systems with POWER8 technology. The breadth of I/O options has also been increased with native, native SR-IOV, and VIOS support of a new 10Gb Ethernet card. In addition, for IBM i 7.2 TR 2, IBM i supports native and VIOS NPIV attachment to the powerful Flash Systems 900, which is leading edge for high-speed disk storage. These announcements deliver support for the latest technologies that complement the growing workload needs on the Power Systems with POWER8 technology to meet the demands for higher capacity and smaller footprint than were previously possible.
Additional hardware-related enhancements include:
Besides the hardware announcements that are supported by IBM i, the IBM i operating system itself has included some enhancements for existing hardware features and offerings:
SAN Multipath support for Tape Drives (IBM i 7.2 TR2 only)
Configuring IBM i with tape libraries and tape drives in a SAN configuration that has multiple paths has been complex. LUN masking and other techniques must be used, and recovering a path failure has required a reconfiguration of the SAN.
With IBM i 7.2 TR2, IBM i support of multiple path tape configurations has been simplified. An operational path is selected at Vary On time. The partition will use only one path at a time and will attempt to use the preferred path when the configuration is activated.
An IBM i multipath tape configuration allows up to eight paths. The attachment may be native to the IBM i partition or via a VIOS NPIV configuration or a mix. The tape drives in the configuration may be in a tape library or stand-alone. Supported tape drives are:
SAS adapter availability enhancement
Customers with SAS dual adapter configurations that use system-level mirroring and encounter some types of adapter and disk failures may experience temporary performance degradations. Customers with RAID-protected dual adapter configurations encounter similar temporary performance degradations if they encounter some types of adapter errors or perform adapter concurrent maintenance operations.
Innovative improvements have been made in IBM i 7.2 TR 2 and IBM i 7.1 TR 10 to drastically reduce the recovery time for some of those scenarios. The breadth of impact for some of the scenarios has been greatly reduced also, to not affect the operation of active paths. These improvements apply to the following adapters and controllers:

IBM i 7.2 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 IBM 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 IBM 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 IBM i together. The preintegration and testing of IBM 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 IBM 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 IBM i is an integrated component that is built on a set of integrated storage management unique to IBM i and its predecessors. This storage management is based on the single-level storage architecture that treats all of the storage managed by IBM 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 IBM i running for days, weeks, and months without unexpected restarting of the operating system.
Several architectural attributes of IBM i have contributed to the stability of the system over the years. First, applications compiled on IBM i are compiled to a set of intermediate code instructions defined as the Technology Independent Machine Interface (TIMI). This enables IBM 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 is a tremendous business advantage and it allows the movement of software developed and compiled several years to even decades before to run on later generations of the IBM 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 IBM 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 deliver excellent business value to its users.
