You can follow the instructions in this topic to install i5/OS™ PASE on your server.
i5/OS PASE is available free of charge on all iSeries™ servers. It is recommended that you install i5/OS PASE; some system software, such as the enhanced Domain Name System (DNS) server and the ILE C++ compiler, requires i5/OS PASE support.
To install i5/OS PASE on your server, complete the following steps:
i5/OS PASE provides a subset of the AIX® runtime libraries on the i5/OS system. The i5/OS license authorizes you to use any library code shipped with i5/OS. This license does not imply a license to AIX libraries that were not shipped with i5/OS PASE. All AIX products are separately licensed by IBM®.
As you begin porting your own applications to i5/OS PASE, you might find that your application has dependencies on AIX libraries that were not shipped with i5/OS PASE. Before porting these libraries to the i5/OS system, you should determine which software product provided those libraries and examine the terms and conditions of the license agreement for that software product. It might be necessary to work with IBM or a third party to port additional middleware dependencies to the i5/OS system. You should investigate every licensing agreement involved with the code you are porting before you start porting. If you need to find out about license agreements in place against libraries that you believe belong to IBM, contact your IBM marketing representative, one of the IBM porting centers, the Custom Technology Center in Rochester, or PartnerWorld® for Developers.
