Typical porting process flow
PartnerWorld offers a process for assessing the ease of portability of UNIX applications written in C or C++. The solution provider runs a shell script against the application's unstripped binary to assess its use of APIs -- systems services and database calls. The shell script and usage instructions are found on the API Analysis page. The provider then emails the results to the PartnerWorld porting team where we compare iSeries API support across a variety of programming models, including ILE and PASE.
Although it is hard to generalize and each application must considered individually, many UNIX applications are suitable to be ported in a cost-effective way to iSeries via either ILE or PASE. The report resulting from the technical analysis is used to help us determine where the application has a good fit technically, and becomes part of a wider business assessment by IBM and the solution provider of getting the application to iSeries.
A general flow for the porting process looks like the following:
Total time to market varies depending on selected deployment strategy:
- Intent is to minimize time to port (historically the most expensive)
- Tailoring' step(s) optional
