ISVs can use the Porting your UNIX or Linux on x86 solution to Linux for IBM System z mainframe server platforms roadmap to determine the steps that they might need to review and execute in taking their existing application on either UNIX or Linux on x86 platforms and enable that application to the Linux for IBM System z mainframe server platforms. You can also discover more roadmaps for related tasks.

Take your application on UNIX® or Linux® on x86 and port it (or, in the case of an existing Linux product, simply enable it) to the IBM System z™ mainframe environment! This roadmap will give you plenty of advice and pointers to IBM programs and facilities to help you enable your application to Linux on System z. The term System z refers to the IBM zSeries® and IBM System z9®, z10™, and zEnterprise™ hardware platforms, all of which support a 64-bit architecture (unlike the IBM S/390® platform which was 31 bit only).

Using this roadmap and enabling your product will help expand your application's marketplace to new customers who are using the System z servers. Your customers will inherit the System z hardware strengths, such as enhanced high reliability and qualities of service. Your application, running on System z is combined with the advanced IBM z/Architecture® technology and the economy of Linux to provide a total solution that can assist your customers in lowering their total cost of ownership (TCO) or in using an architecturally rich platform.

As part of the Linux for System z ISV Enablement program, our ISV team in Poughkeepsie offers additional ISV-only educational opportunities such as the Technical Disclosure Meetings (TDMs) and Linux Distribution Partner teleconference calls. Email us for details. If you have any further questions about enabling your Linux-based application to IBM System z, send an e-mail to using "Linux on System z" in the subject line.
