Prerequisites for using iSeries Access for Linux

Use this information to learn about the iSeries™ server and Linux^® requirements for using iSeries Access for Linux.

iSeries server requirements for running iSeries Access for Linux

Connections to iSeries servers running i5/OS™, release V5R2 or V5R3, are supported. Using the product with earlier releases, may produce unexpected results.

The QUSER user profile must be enabled. From an iSeries command line type the following:

DSPUSRPRF USRPRF(QUSER) 
Press ENTER to display the status for QUSER. 
Use the CHGUSRPRF command to change the profile if necessary.

The host servers must be started. Type STRHOSTSVR and press ENTER to start the OS/400^® host servers.
TCP/IP must be started. To start TCP/IP, you must have the TCP/IP Connectivity Utilities (i5/OS licensed program 5722-TC1) installed on the server. For more information on host server options and TCP/IP, see the TCP/IP topic in the iSeries Information Center.

Linux requirements for running iSeries Access for Linux

GNU C Library (GLibc 2.2)
Red Hat package manager (RPM 3.0)
Runtime environment (OpenMotif 2.0 or later for the 5250 emulator)
unixODBC driver manager version 2.0.11 or later must be installed on the client. See the unixODBC Project web site for more information on the driver manager and to download the latest level of the driver manager.

Note: If you recompile the unixODBC driver manager, the ./configure --prefix default is /usr/local. If you use this default, update your shared library (/etc/ld.so.conf) and executable paths to include it.
