PASE

PASE, an acronym for Portable Application Solutions Environment, is an IBM-supplied licensed program which provides a subset of AIX functionality on the iSeries.

This can be used to port a number of traditionally unix-only capabilites to the iSeries, including zip/unzip, sftp, tcl and GnuPGP.

When released as part of V4R4, V4R5 and V5R1, PASE was a chargeable LPP. As of V5R2 and later, it has become a no-charge option.

PASE is installed as option 33 of the OS/400 LPP. On V5R3 it is 5722SS1, Option 33.

Shells

PASE includes three shells: Korn (ksh), Bourne (bsh), and C (csh). The default shell, located in the IFS at /QOpenSys/usr/bin/sh, is the Korn shell.

AIX compatability

AIX release	V4R4	V4R5	V5R1	V5R2	V5R3	V5R4	6.1	7.1
4.2 (32-bit)	Yes (4.2.1)	Yes	Yes	Yes	Yes	Unknown	No	No
4.3 (32-bit)	No	Yes (4.3.3)	Yes	Yes	Yes	Yes	Yes	No
4.3 (64-bit)	No	No	Yes (4.3.3)	No	No	No	No	No
5.1 (32/64-bit)	No	No	No	Yes	Yes	Yes	Yes	Yes
5.2 (32/64-bit)	No	No	No	No	Yes	Yes	Yes	Yes
5.3 (32/64-bit)	No	No	No	No	No	Yes	Yes	Yes
6.1 (32/64-bit)	No	No	No	No	No	No	No	Yes

Because the underlying hardware is POWER Systems, PASE can run many AIX programs compiled for POWER hardware. IBM have a list of AIX tools that can be loaded onto PASE. AIX Toolbox for Linux applications

Java

In V5R4, the 32bit version of the JVM runs in PASE.

Perl

In addition to traditional *ux-style utilities, PASE can support various open source software like Perl. Often, the AIX version of a package can be used as-is in PASE. Sometimes you'll need RPM; see PASE_Open_Source. Perl itself can be installed via 5799-PTL.
