IBM OS/400 Version 5 Release 1 Delivers Enhancements that Add Power to IBM iSeries
At a Glance
V5R1 OS/400 enhancements:
For ordering, contact:
Your IBM representative, an IBM Business Partner, or IBM Americas Call Centers at 800-IBM-CALL (Reference: AE001).
OS/400® V5R1 gives you one of the most flexible application environments in the industry with support for Linux, Lotus® Domino, Java, Microsoft Windows, UNIX®, and IBM iSeries applications, combining high availability with superior workload management and logical partitions.
With OS/400 V5R1, a business can simply and rapidly deploy e-business applications with seamless integration of existing applications and data. With extensions to its robust security and networking options, OS/400 V5R1 enables business-to-business connectivity through the supply chain and to customers.
The face of OS/400 is forever changed with extensive graphical interface enhancements providing visualization, wizards, and integration for simplicity of advanced operations from PCs and pervasive or mobile devices. Operating your iSeries server has never been this simple.
OS/400 V5R1 and iSeries deliver robust reliability and scalability for the fast growing, open-source Linux environment. Now the next generation of Web-enabled Linux applications can be quickly deployed and managed in a single, partitioned server alongside current business applications.
With dynamic and granular logical partitions, OS/400 V5R1 makes it easier than ever to manage multiple applications in a single server. Also, iSeries can now provide a storage area network (SAN) for directly attached Windows 2000 Servers.
New high-availability options include faster, less expensive system-to-system clustering options and the ability to switch applications, data, and resources between two iSeries servers.
In addition, V5R1 includes a broad range of enhancements for e-business and application enablement, security, TCP/IP, database, Java, directory services, OS/400 PASE, Internet printing, and many more.
IBM is committed to supporting your choice of platform and operating systems a commitment we have extended to include Linux, the open-source operating system. Linux will enable a new stream of e-business applications that complement the strengths of the iSeries as an integrated core business solution. Linux can benefit from important strengths and reliability features of the iSeries architecture.
iSeries has been enhanced to support Linux running in a secondary logical partition. The primary partition must run OS/400 V5R1 and can support up to 31 Linux partitions depending on the iSeries model. Selected new processor features for iSeries Model 270, 820, and 840 servers1 will allow Linux to run in a shared processor pool, where one processor can be shared between four OS/400s and Linux partitions. On existing n-way processor features for iSeries Model 820, 830, and 840 servers2, Linux requires a minimum of one processor per Linux environment. iSeries LPAR gives you the flexibility to move processor and memory resources between Linux partitions. This movement requires a restart of the affected Linux partitions.
iSeries Linux partitions also support a wide selection of I/O options. A Linux partition can utilize the new Virtual LAN capability to establish multiple high-speed TCP/IP connections between logical partitions without additional communication hardware. iSeries disk and removable media devices can be configured for Linux partitions using the OS/400 Network Server Description (NWSD) commands to deliver a simple, flexible, and integrated storage solution. Additionally, Linux can utilize selected iSeries I/O adapters (IOAs) and devices directly. These configuration options enable a wide selection of iSeries solutions.
To enable Linux to run on iSeries, IBM has made contributions to the
open-source 32-bit kernel Version 2.4 for PowerPC®. IBM is
currently working with the Linux community to create Linux distributions
for iSeries. IBM plans to support selected Linux distributions running
on iSeries in the second half of 2001.

LPAR allows for the simultaneous running of multiple independent systems each with processor, memory, and disk resources within an iSeries. This capability was first introduced in V4R4, updated in V4R5, and now is significantly enhanced with V5R1.
LPAR enhancements for selected iSeries Models 8xx and 270 and AS/400 Models 7xx, 6xx, and Sx0 include:
LPAR enhancements for selected iSeries Models 8xx and 270 include:
These LPAR functional enhancements require an OS/400 V5R1 primary partition.
Windows Server Integration Enhancements
iSeries is enhanced with additional Windows server integration facilities. These enhancements enable iSeries to support larger and more complex Windows applications and offer additional tools to help reduce the cost of managing Windows server environments.
Attachment of N-Way xSeries Servers: iSeries now supports the attachment of n-way xSeries servers via the High Speed Link. With the new Integrated xSeries Adapter, selected xSeries servers running Windows 2000 Server can be utilized to extend Windows application scalability, while retaining the storage consolidation and systems management advantages of the Integrated xSeries Server.
Enhanced Hardware Support: Enhancements for the Integrated xSeries Server includes support for up to 32 servers on selected iSeries models, support for the 1 GB Ethernet LAN adapter, and support for the iSeries DVD device.
Operations Navigator Support for Windows Disk and User Management: Additional facilities have been added to Operations Navigator for managing Integrated xSeries Servers and xSeries servers directly attached to iSeries via the Integrated xSeries Adapter. In addition to server management, Operations Navigator now supports disk and user management for these Windows servers. Enhancements include the capability to create, delete, copy, link, unlink, and show status for Windows server disks. Administrators can also manage OS/400 user profiles that are enrolled into a Windows server environment.
Increased Storage Capacity and Availability: iSeries SAN support for Windows servers has also been enhanced. For Windows 2000 Servers, the number of storage spaces that can be defined has increased from a maximum of 16 to 32. With a storage space supporting up to 64 GB of disk, each Windows server can now access approximately 2 TB of disk space. Up to 16 of these storage spaces can be added without requiring a shut down of Windows 2000 Server.
Improved Availability via Independent Auxiliary Storage Pools (IASPs): With the introduction of IASPs, additional availability options are available for the integrated Windows environments. Since the Windows operating system and data can be installed in an IASP, the storage spaces associated with Integrated xSeries Servers or direct attached xSeries servers can be switched to another iSeries server with a duplicate hardware environment.
For more information, refer to Hardware Announcement
, dated April 23, 2001.
Advanced User Interface
V5R1 delivers two times more advanced GUI function to iSeries and AS/400 customers than the previous release. Operations Navigator is significantly expanded in this release with industry-leading, integrated systems management via easy-to-use graphical interface.
Other ease-of-use initiatives for V5R1 include the addition of numerous GUI extensions to existing Operations Navigator functions, the creation of numerous configuration and administration wizards (many of which are in the new GUI areas listed above), and a new iSeries Information Center online documentation available on the Web or CD.
Management Central-Pervasive: Management Central-Pervasive (MC-Pervasive) allows iSeries network administrators to keep an eye on their iSeries or AS/400 servers while they are away from their workstation or office. Using an Internet-capable cellular phone, PDA with a wireless modem, or a Web browser, administrators can monitor and manage their iSeries systems.
V5R1 enhancements for MC-Pervasive include:
These additional V5R1 enhancements are available via an English-only PTF. Customers interested in using Pervasive need to refer to the following IBM Web site to obtain the PTF numbers to load the code and MRI for Pervasive:
EZ Setup now provides a complete set-up path for many users and allows one to go from out-of-box to serving a business in one quick and easy path. EZ Setup is now a part of iSeries Client Access Express and is on the "Setup and Operations" CD-ROM (shipped with all orders).
Information Center for iSeries: The Information Center for iSeries provides the starting point for finding iSeries technical information and is available on a CD-ROM shipped with OS/400. It is also on the Internet at:
In V5R1, the Supplemental Library on PDF is integrated with the
Information Center to give you a one-stop place to get technical
information. You can search the PDF and HTML files in one search at the
Internet site. In V5R1, the Information Center install provides a wizard
to install the Information Center to an intranet server from the iSeries.
The wizard can even configure your HTTP server and set up search on the
Extensible Markup Language (XML) Enablers
XML is one of the key technologies fueling growth of e-business and mobile e-business solutions. XML is becoming the standard way to represent data in a portable, reusable format for use in a number of solutions ranging from B2B solutions that link together trading partners to pervasive computing applications, which connect mobile devices such as cell phones to core business solutions.
IBM and iSeries are committed to supporting XML. This support is demonstrated by the suite of XML application enablers delivered with OS/400 in V5R1, providing a core of XML services for applications to build on. The XML application enablers provided in V5R1 include:
OS/400 Cluster Resource Services
Clustering, initially introduced in V4R4, expands the underpinning to improve overall availability of your critical resources beyond what you can achieve in a single system environment. Additional significant functions are expanded with V5R1 that allow even more flexibility and improved availability. New capabilities include:
HA Switchable Resources, OS/400 Option 41
HA Switchable Resources, a new chargeable option of OS/400, gives you the capability to achieve a highly available environment using switchable resources. The resources are physically switched between systems so that only one copy of the resource is required. Included as part of Option 41 are:
To define switchable independent ASPs or to use the IBM Cluster Management Utility, you must have OS/400 Option 41, HA Switchable Resources installed on your system. You also must have a valid license key for Option 41.
For information on HA Switchable Resource hardware features, refer to Hardware Announcement 201-117 , dated April 23, 2001.
Additional Significant Enhancements in OS/400® V5R1
OS/400 PASE, option 33 of the operating system, is an integrated component of OS/400 that adds in V5R1 a subset of AIX® Version 4.3.3 functionality to support running UNIX® applications. OS/400 PASE is supported on all iSeries models, and any AS/400e server Models 6xx or Sxx, or later.
OS/400 PASE applications run directly on the hardware and take advantage of OS/400 services such as file systems, security, and DB2 UDB®. OS/400 PASE applications run in a normal OS/400 job and are managed using standard OS/400 operations and management facilities.
Some of the significant enhancements to OS/400 PASE in V5R1 include:
More information on OS/400 PASE can be found at:
(Search on PASE)
IBM HTTP Server for iSeries
IBM HTTP Server for iSeries supports new enhancements that improve performance and availability of the HTTP servers. These enhancements include:
New Search enhancements that improve the search capabilities of the HTTP server include:
In V5R1, IBM HTTP Server for iSeries now includes the original IBM HTTP Server and the IBM HTTP Server (powered by Apache), which was announced for V4R5. Refer to Software Announcement 200-340 , dated October 3, 2000, or at:
Apache, a freeware HTTP server, is open-source software that implements the industry-standard HTTP/1.1 protocol with a focus on being highly configurable and easily extendible. It is built for several server platforms and distributed under the Apache Software License by the Apache Software Foundation. For more information, refer to:
Digital Signature and Object Signing: Support for digital signatures on several OS/400 object types adds an even greater degree of integrity. Software providers, or system administrators, can add digital signatures to software, and use those signatures to verify the source of the software and to ensure that the software has not been changed since it was signed. This added layer of protection against altered software, unintentional or malicious, is also being used by the operating system to protect itself from unauthorized changes.
Program Creation Data Retained: Program creation data will be retained even when observable information is removed for programs created for V5R1. If observable information is removed, the creation data cannot be retrieved by any supported interface, but the system licensed internal code will be able to use it to recreate the program. This new function gives customers more control over the programs they choose to put on their systems, because they can cause programs to be recreated as part of the restore process. This program recreation choice is expressed by specifying the FRCOBJCVN(*YES *ALL) parameter on the RSTOBJ or RSTLIB commands. Recreating a program takes advantage of hardware changes and enhancements in optimizing translator technology. Recreating a program may also enhance its integrity because recreation removes any alterations that may have been made to its executable instructions.
Programs that include creation data and are found to have been altered in certain ways are recreated automatically when they are restored onto a system, to further reduce the potential for security or integrity exposures. This action also occurred on previous releases of OS/400, but its effectiveness should be improved now that more programs will include creation data.
Enhanced Password Protection:
Support is added to the system to enable case sensitive user profile
passwords up to 128 characters in length with a larger character set.
This support provides greater security for the user profile password. It
is enabled via a new system value called QPWDLVL. The default value of
the QPWDLVL system value is zero. It maintains previous release
compatibility of 10 character passwords. Before taking advantage of the
longer passwords, it is recommended you review the security reference
manual for a complete description of the potential compatibility
arrangements when using the new support.
TCP/IP Simplification Extensions: OS/400 Domain Name System (DNS) services are enhanced significantly in this release. The new V5R1 OS/400 DNS services are based on the widely used industry-standard DNS reference implementation known as BIND version 8.2. Topping the list of enhancements are the new dynamic update capabilities, which have transformed the DNS into a Dynamic DNS (DDNS). Combined with enhancements made to the iSeries Dynamic Host Configuration Protocol (DHCP) server that allow it to be configured to send dynamic DNS update transactions, iSeries now supports an integrated Dynamic IP solution that automatically manages TCP/IP addresses and their associated DNS host names on your networks.
Network Quality of Service (QoS): In V5R1, iSeries gives you the ability to control and manage TCP/IP traffic in the network and take advantage of the leading-edge networking Quality of Service (QoS) functions contained in routers and switches. The iSeries QoS functions for managing TCP/IP traffic give you the ability to drop, mark, and shape TCP/IP traffic based on the QoS policy being applied. In addition, QoS admission control capability is added for controlling bandwidth management requests. The QoS functions supported are:
Network Security and Virtual Private Networking (VPN): iSeries VPN support, introduced in V4R4, is enhanced with additional security, greater reliability, improved performance, and is easier to use. Operations Navigator is redesigned to intuitively navigate VPN configurations, and you can use the VPN wizard to setup and implement your network security policy. Digital certificates add a scalable and secure mechanism for cryptographic operations, and in V5R1 you can now use them in your VPN configurations to authenticate the identities of the VPN endpoints. An integral part of iSeries VPN is IP Packet Filtering, and in V5R1 this component is enhanced to allow filter activation and deactivation on a per-interface basis.
Networking Software Management and System Setup: Several TCP/IP management enhancements in V5R1 give the network administrator more control when monitoring their TCP/IP network and troubleshooting networking problems. The enhancements include:
Internet Setup Wizard: The iSeries Internet Setup Wizard simplifies the steps required to connect your iSeries to the Internet and provide application and Web serving. The wizard allows you to connect your iSeries to an ISP over a dial-up connection or directly through a LAN connection. The Wizard can also connect your intranet iSeries to the Internet through a firewall or router and allow for Web and application serving by the iSeries over that connection.
TCP/IP Performance Improvements: TCP/IP performance needs to keep pace with the new emerging workloads that go beyond the raw throughput of a single connection. The Domino server and Web servers need fast throughput as well as quick connection establishment for the thousands of connections. Through continued performance tuning and path-length reductions, improvements have been obtained for throughput rates, multiprocessor scalability, and connection establishment abilities.
Point-to-Point (PPP) Connectivity Enhancements:
Operations Navigator enhancements improve the ease-of-use when
configuring and managing PPP connectivity. Significant enhancements in
function and the GUI capabilities improve the iSeries PPP connectivity.
Operations Console is Windows-based communications software that provides a single connectivity solution for all platform management applications including legacy 5250 console support, a remote control panel GUI, and the Operations Navigator/Management Central platform management applications. Connectivity choices include null-modem, cable-connected async communications, dial-up async communications, and now Ethernet/Token-Ring Local Area Networking with V5R1. Additional new features include:
PC5250 supports the LAN connectivity option of Operations Console and
supports a version of SSL implemented by Operations Console that supports
device authentication, but without the use of certificates.
DB2 UDB for iSeries Enhancements
Business-to-business enablement is the theme of the key enhancements for DB2® UDB for iSeries in V5R1. Following are the new functions:
Plus much more. The Toolbox runs on Java-compatible JVMs running 1.1.8, 1.2.2 or 1.3. Toolbox source is available via the JTOpen project. For more information, access the Toolbox Web page:
Developer Kit for Java Updates: Options for Java 1.1.8 and Java2 Standard Editions (J2SE) 1.2.2 and 1.3.0 are shipped with the V5R1 Developer Kit for Java, providing concurrent support for all three major versions of Java (1.1, 1.2, and 1.3).
Performance enhancements in V5R1 include:
Several limits to growth have been enhanced, most notably, the maximum object size has increased from 16 MB to 32 GB.
Operations Navigator enhancements include support for displaying the properties of Java classes and jar files, the ability to compile Java files, interactive support for Input and Output, as well as automating RAWT connections when launching Java programs from Operations Navigator.
For additional Java information, including service requirements, refer to the online publication IBM Developer Kit for Java from the following iSeries Book Server at:
OS/400 Directory Services in V5R1 now supports SecureWay Directory Version 3.2. Examples of SecureWay products dependent on the directory for some of their distributed functions are:
Version 3.2 of the SecureWay Directory provides the following industry-leading innovations:
In addition to the SecureWay Directory V3.2 updates, the following enhancements are made for Directory Services on OS/400:
Print and e-Print for iSeries: V5R1 provides a wide range of new capabilities that enable the iSeries to address the print and communications requirements of e-business and network applications. Those capabilities include:
These enhancements are available with OS/400, PSF/400, and a new iSeries product, Infoprint® Server for iSeries.
Refer to Software Announcement 201-122 , dated April 23, 2001.
Internet Printing Server for iSeries: The IPP defines an industry-standard method of delivering print jobs using Internet technologies providing for Web-enabled print around the world. The IPP protocol was developed by the Printer Working Group, a consortium of all major companies involved in network printing. IPP is fast becoming the single standard interface for printing on the Internet, with broad vendor implementation and customer acceptance.
The IPP Server for iSeries, included in OS/400, provides an IPP Version 1.0 compatible print server for the iSeries. This means the iSeries will accept IPP print requests and then serve the print file to the designated printer via traditional means. Thus, even if a printer does not actually support IPP, the iSeries will accept IPP requests for that printer and then print to that printer with other protocols. The IPP Server for iSeries allows business travelers, telecommuters, and anyone working remotely to submit and manage print jobs on a distant iSeries.
IPP is built on top of HTTP, which in turn runs over TCP/IP. Customers can now use the same print solution on local area networks, intranets, and the Internet. The same process used to send a print document to the department printer down the hall can be used to send the document to the corporate printer across the country.
The IPP Server for iSeries provides security features for user authentication and encryption of print jobs using Secure Sockets Layer 3 (SSL).
PSF/400 is also enhanced to provide:
New support for LDAP Directories: New support has been added to allow information about iSeries printers and NetServer print shares to be published into LDAP directories. This allows the user to write applications that query the LDAP directory for iSeries printer information such as a printer's location or capabilities. It also allows the user to configure iSeries printers directly on their Windows 2000 desktop by using the Add Printer wizard available in Windows 2000 and specifying that the information necessary to configure the printer be obtained from the Windows 2000 Active Directory.
Unicode (UCS-2) Print Data Streams, Fonts, and Printers: This support gives OS/400 users the ability to print Unicode (UCS-2) data on existing printer hardware. Support for Unicode printing is limited to Unicode code points that represent font glyphs. Any Unicode semantics are lost. Two methods are provided to achieve Unicode printing for DDS printer files:
Enhanced Chinese Language Support
OS/400 V5R1 provides enhanced Chinese language support. In addition to
existing GB 2312 and GBK character support, OS/400 V5R1 is enabled to
support 6,582 Unicode Extension-A and 1,948 non-Han characters
(Mongolian, Uygur, Tibetan, and Yi). Customers who plan to use this
enhanced language support must apply PTF SE01058. The planned
availability date for this PTF is May 25, 2001.
The iSeries ESP initiative helps you easily manage your system, streamline your support, and reduce risk for your business. ESP is total solutions support, personalized for you in the form you need it. ESP involves support over the Internet, voice, and on-site support, along with support integrated into the product.
For a detailed description of previously announced ESP capabilities, refer to Software Announcement 200-340 , dated October 3, 2000.
Function previously announced and available via a PTF is now part of OS/400 V5R1.
In V5R1, new ESP capabilities include Internet support and support integrated into OS/400.
More Flexibility for Universal Connection: IBM gives you more options for Electronic Customer Support (ECS) and Electronic Service Agent connectivity through Universal Connection. In addition to dial-up support over TCP/IP via ATT Global Network Services, with V5R1 the Universal Connection also supports Internet connections using a VPN. This can be used for:
IBM offers connections through VPN to provide secure connections over the Internet.
The Universal Connection enables a variety of ESP support tools that report inventories of software and hardware on your machine to IBM so you can get personalized electronic support based on your system data. This helps streamline your support process so you can spend more time running your business rather than maintaining your systems. You control the transmission of data to use (what and when it is sent) and we secure your customer data behind a firewall and use the data to appropriately provide you our world class, personalized support. Personalized data enabled by the Universal Connection includes:
The ability to configure VPN connections is enabled in Client Access Family Service Pack 1, available at:
To take advantage of these capabilities, use the EZ Setup wizard at system setup, or use the ESP wizard, located under Management Central in Operations Navigator.
For additional detail on these new ESP functions, refer to:
Simplified Ordering with Software Upgrade Assistant (SUA): SUA is a Web-based tool that simplifies some software upgrade orders. If the customer has Software Subscription and is registered through IBM Electronic Services, they can use SUA to directly order release upgrades based on the software subscription they have and the products they want upgraded.
SUA is updated to reflect new or changed iSeries and AS/400e software. The capability to use SUA for upgrades to V5R1 is planned to be available later this year. Refer to the availability schedule for product support updates and V5R1 support, and to learn more about SUA at:
To use SUA, go to:
Integrated File System
High availability is significantly enhanced by the addition of several key items, including support for:
AS/400 NetServer is enhanced so that the iSeries can operate as the Logon Server for Windows clients. The iSeries can be used to authenticate logging onto Windows, provide the home directory, and logon scripts to the Windows user. Additionally, Windows user profiles including Desktop, Start Menu, Favorites, and policies can be stored and retrieved from an iSeries server. A Windows NT or Windows 2000 server is no longer needed in the network to provide these functions.
AS/400 NetServer dramatically reduces the number of times that OS/400 user profiles become disabled due to Windows programmatically attempting invalid signons to access the OS/400 without compromising security. Additionally, when users do cause their user profiles to become disabled due to several attempts with different invalid passwords, AS/400 NetServer provides new GUI support through a Disabled User ID's menu item off the AS/400 NetServer menu of Operations Navigator to reenable those user profiles. This support has also been made available through an API on OS/400. These changes can reduce the number of times that user profiles become disabled and improve the ease with which disabled users can be managed.
iSeries has enhanced the allowable characters in a password and the length of a password to be more compatible with Windows. This helps customers who like to have their Windows and iSeries passwords match. AS/400 NetServer also provides support for the NTLMV2 password hash that the Windows PCs can be configured to use to provide better password protection on the network.
User IDs longer than 10 characters are now truncated to 10 characters when checking for an iSeries user ID instead of being rejected. Now a userid such as Administrator on Windows would be the same as ADMINISTRA on the iSeries. This should help compatibility between Windows and iSeries user IDs.
A new AS/400 NetServer Setup Wizard is now part of Operations Navigator that guides you through setting up your AS/400 NetServer based on the types of Client Access clients being used. This new Setup Wizard also helps the user configure logon support.
AS/400 NetServer now supports access to files larger than 2 GB in the Integrated File System.
Through Operations Navigator and APIs, a new Session Identifier can be used to allow better management and tracking of AS/400 NetServer sessions. This is extremely important in a Windows Terminal Serving environment where many users have sessions through a single Windows system. Now sessions can be ended or properties observed on single sessions rather than all the sessions coming from a single system.
NT Background services can now access the AS/400 NetServer without user intervention.
Printer Shares can now be published in Directory Services (LDAP) for use by Windows 2000 systems using Active Directory to find printers.
ILE C and C++ Teraspace Enhancements
Teraspace is temporary storage that provides up to a terabyte of contiguous, private storage to an OS/400 job. C and C++ programs can now optionally obtain their static and automatic storage from teraspace. A new lightweight, 8-byte pointer is now available for accessing teraspace. Use of 8-byte pointers can improve execution performance and reduce the memory rootprint of pointer-intensive applications. Together, teraspace working storage and 8-byte pointers significantly ease the porting of certain applications to iSeries.
Improved C/C++ and Java Performance
Enhancements to compiler optimizations ensure that programs leverage the
latest hardware and software features. Compiler optimization for the
iSeries servers is taken to the next step with the introduction of
state-of-the-art analysis techniques that extend optimizations across
procedures and *MODULE object boundaries. Interprocedural analysis (IPA)
has the potential to significantly improve the execution performance of
applications written in ILE C and ILE C++.
Spool File Enhancements
More spooled files allowed for a job: Customers have been reaching the limit of 9,999 spooled files per job. This limit has now been increased to 999,999 spooled files. This is controlled system wide via a system value QMAXSPLF. Because of the increase in the number of spooled files per job, various interfaces had to change to accommodate the larger spooled file number (four to six digits). This could result in the need for applications changes. The customer needs to review the iSeries Memorandum to Users before using the new function (the system default is to retain the old limit of 9,999 spooled files per job).
Now you can find a spooled file just created with superb accuracy: Customers have had difficulty determining the fully qualified job name of a spooled file when the spooled file gets created under a QPRTJOB. This situation occurs when a job has changed from the original user to another user profile. Support has been added to create a data queue entry each time a spooled file is created within the tread or job. The data queue support is enabled through the use of environment variables. Customers should refer to the Printer Device Programming manual for more details (this support has PTFs all the way back to V4R2).
Programmatically monitor your remote writers: Customers need the ability to retrieve status of a remote writer. The retrieve writer information API QSPRWTRI has been enhanced to allow retrieval of remote writer information. This enables customers to write programs that can monitor and manage remote writers.
Increased Maximum Capacities
V5R1 provides enhanced system scalability by increasing the following maximum capacities:
In V5R1, the following enhancements are provided to support Optical Removable Media (Magneto Optical (MO), Write Once Read Many (WORM), CD-ROM, and DVD-RAM):
New Trace Job Facility
A new job trace facility introduces several changes needed in TRCJOB. The new job trace support should be used instead of TRCJOB. The new job trace facility includes four new CL commands (STRTRC, ENDTRC, PRTTRC, and DLTTRC) and includes the following enhancements:
Cryptographic Coprocessor Enhancements
In V5R1, there are new capabilities associated with the Cryptographic Coprocessors. The new capabilities are the following:
International Components for Unicode
The International Components for Unicode, option 39 of OS/400, is a C and C++ library that adds robust and full-featured Unicode support. It provides internationalization utilities for writing global applications in ILE programming languages.
As companies weave e-Commerce on a global scale into their fundamental business processes, their prospective customers, established customers, and active business partners can take advantage of increased revenue, decreased expenses, and better customer communications and savings through software internationalization.
Software internationalization is the development process using libraries, like the International Components for Unicode (ICU) libraries, that enable one single program to work with text in any language, for any place in the world. For example, instead of having software versions for ten different countries, you can use the ICU support to create one version that can work seamlessly and transparently in ten different and unique countries.
The ICU components are an integral part of software development because they hide the cultural nuances and technical complexities of locale-specific software requirements. These complexities provide critical functionality for applications but they do not burden the application developer with the tremendous effort and high cost to build them.
For more information about ICU, refer to:
