IBM Communications Server for AIX, V6 New Features and Implementation Scenarios

Chapter 13. 64-bit SNA applications

IBM Communications Server for AIX, Version 6 introduces support for 64-bit

applications when running with AIX V4.3. Applications written to the APIs

introduced in CS/AIX V5 (LUA, NOF, APPC, CPI-C, CSV, MS) may be

compiled and linked to run in either 32-bit or 64-bit mode. Applications that

use the jCPI-C API or the older CS/AIX V4 APIs do not support 64-bit mode.

13.1 Requirements for 64-bit support

IBM AIX V4.3.2 ML2 or later is required if you intend to compile, link or

execute applications using CS/AIX APIs in 64-bit mode. 64-bit applications

may be compiled and linked on an AIX 32-bit machine, but they must be

executed on an AIX 64-bit machine.

The AIX bos.64bit option must be installed. bos.64bit is part of the AIX base

operating system. AIX 64-bit support is configured using the command

smit

load64bit

.

64-bit support within AIX 4.3 also requires the latest data link control filesets.

Depending on your specific CS/AIX configuration, you may require at least

one of the following filesets at the level indicated:

Table 2. 64-bit fileset requirements

All bos.dlc filesets except sna.dlcchannel and sna.dlcmpc are provided as

part of the bos.dlc.usr package in the AIX base operating system.
