5486LPOpS.fm Draft Document for Review October 18, 2004584 IBM Eserver i5 and iSeries System HandbookOS/400 Portable Application Solutions Environment (5722-SS1 Option33)OS/400 PASE is an integrated runtime that providessimplified porting of selected solution provider UNIXapplications. OS/400 PASE complements and expands theiSeries solution portfolio by focusing on rapidly portingUNIX applications to the iSeries platform.OS/400 PASE is a library of APIs and system services thatenable AIX programs to run in OS/400. It provides asubset of AIX functionality to support running 32-bit and 64-bit UNIX applicationsdirectly on iSeries hardware. OS/400 PASE includes full support for X-Windows.OS/400 PASE applications are created on an AIX workstation and execute oniSeries hardware. As of V5R2, OS/400 PASE applications written in C or C++can be compiled within OS/400 PASE. The environment provides librariescontaining hundreds of basic system APIs that are compatible with: 32-bit applications for AIX 4.2.1 or later 64-bit application for AIX 5.1OS/400 PASE exploits the iSeries processor’s ability to switch between OS/400and AIX runtime modes within an OS/400 job. This allows applications deployedusing OS/400 PASE to run directly on iSeries hardware and take full advantageof OS/400 services such as file systems, security, and DB2 UDB for iSeries.OS/400 PASE is not an operating system. It does not provide support fordeveloping UNIX applications. Any changes or additions required to port UNIXapplications to OS/400 PASE are compiled and linked on an RS/6000®workstation running a level of AIX supported by OS/400 PASE. Applicationsdeployed using OS/400 PASE run in a normal OS/400 job and are managedusing standard OS/400 operations. Serviceability, backup and restore, and otheradministrative tasks are performed using standard OS/400 operations andsystem management facilities.OS/400 PASE contains the same command line interface (CLI) set of APIs forDB2 UDB iSeries that is supported for Integrated Language Environment (ILE).OS/400 PASE (5722-SS1 Option 33)Included in base Header and export file extensions are packaged with OS/400 Option 33Status No charge featureRelated productsFurther information http://www-1.ibm.com/servers/enable/site/porting/iseries/pase
