partition of the operating system. This will enable Linux applications to run on such
iSeries servers with few or no changes required. The Linux kernel will enable a new
stream of e-business applications for the iSeries platform that complements its
strength as an integrated core business solution. Linux applications will benefit from
the iSeries platform's ability to provide resource flexibility, reliability, and connectivity to
other applications on a single server.
• High-Speed Link (HSL) OptiConnect : IBM intends to further leverage the significant
bandwidth, flexibility, and speed of new High-Speed Link (HSL) for system-to-system
connectivity by offering HSL OptiConnect.
• Direct Attach Netfinity Server : IBM intends to support direct AS/400 attachment of
SMP Netfinity servers via the AS/400 High-Speed Link (HSL) bus, retaining the
systems management and disk consolidation features of today's AS/400 Integrated
Netfinity Server.
• Electronic Customer Support (ECS) PM/400e and Service Agent : IBM intends to
support Electronic Customer Support (ECS) running over a TCP/IP connection,
including electronic fix retrieval, problem reporting, and hardware and software
inventory information. PM/400e and Service Agent (formerly known as Service
Director) will also be modified to take advantage of the TCP/IP connection. These
functions will use the V.90 integrated modem that is shipped with the 2xx and 8xx
models. IBM also intends to add fax support for this integrated modem.
• CPA Toolkit : Support for Common Programming APIs (CPA) Toolkit will be
discontinued in future OS/400 releases. OS/400 V4R4 is the last release to support
the CPA Toolkit development environment. CPA applications can be modified on V4R4
and earlier releases only. The CPA Toolkit runtime environment is supported for V4R5.
Software developers and customers are encouraged to migrate CPA applications to
kernel threads, the strategic OS/400 function. Information on migrating from CPA to
kernel threads is available at:
http://www.as400.ibm.com/developer/threads/cpa/roadmap.doc.html
• Altered Program Objects : Some application providers and customers alter their
program objects. Today you cannot recreate a program object without source code on
an iSeries or AS/400 server if observable information, which includes program creation
data, has been removed. A future enhancement to OS/400 will retain program creation
data when observable information is removed, allowing the program to be recreated at
the customer's option. Recreating a program helps ensure its integrity and allows you
to take advantage of new hardware or enhancements in translator technology.
However, when a program is recreated, alterations made to the program object are not
retained. Programs that depend on alterations may fail or behave in an unexpected
manner should the customer choose to recreate them. Customers should consult their
application providers regarding potential impacts of program re-creation.
Note : IBM recommends against altering program objects because altered programs may
bypass checks made by OS/400 that help ensure system integrity and security.
