not used with Direct I/O. The iSeries configurator supports ordering IOAs without IOPs when

a Linux partition is defined.

The Linux console is a PC connected to the iSeries primary or hosting partition via a TCP/IP

LAN. Operations Console with LAN Connectivity, part of Client Access Express, is required to

establish a secure connection to OS/400 V5R1. A Telnet environment is then used to connect

into the Linux environment through the Virtual LAN. The console is used for installation and

problem determination operations. There is no console adapter in the Linux partition.

To enable Linux to run on iSeries, IBM uses open source 32-bit kernel version 2.4 for

PowerPC. Linux for iSeries is available directly from Linux distributors. IBM is currently

working with:

• Red Hat, Inc.

• SuSE Linux AG

• TurboLinux, Inc.

iSeries ODBC Driver for Linux

Linux programs written to the ODBC interface are able to access iSeries database data via

ODBC driver for Linux. The ODBC driver is called to carry out database requests. These

requests are sent to the iSeries for processing via the database host server over an IP

Highlights of ODBC connection include:

• The Linux ODBC driver conforms to ODBC 3.5 specifications.

• The iSeries ODBC driver for Linux connects to OS/400 V4R5 and later.

• The driver is tested and supported only for the versions of Linux that can install in an

iSeries LPAR partition.

• The driver communicates with the iSeries via existing OS/400 host servers.

• Beta test code is scheduled to be available in the fourth quarter 2001. An English

version is planned to be available in the first half of 2002. Both will be supplied as

downloads on the Web.

Prior to V4R4, the iSeries server offered multi-system coupling that provided peer or tiered

node clusters, constructed by ISVs using distributed data management and journaling. The

Operating System/400 (5722-SS1)
