zSeries Overview
Porting
Porting to zSeries servers with Unix System Services under the z/OS operating
system is similar to porting to other UNIX-based platforms. Although all
UNIX operating systems, including Unix System Services, share many similarities,
there are differences between each type of UNIX which may require platform-specific
changes. Some applications may operate across several UNIX platforms, but
generally some porting effort is required.
zSeries servers now also run the Linux operating system natively. For those
applications currently running on Linux on other platforms, it is now possible
to run your application with little or no modification on either Red Hat
Linux or SuSE Linux on zSeries.
Here, you will find resources to aid you in your zSeries porting effort.
This includes information on porting from other UNIX platforms such as
HP-UX or Sun Solaris to the Unix System Services environment under z/OS,
as well as Linux. You will also find reference materials such as white papers
and books that provide in-depth information on topics relevant to the porting
process.

Infrastructure
Porting the application code itself to the zSeries platform is one
part of a successful solution on a zSeries server. There are also certain recurring
tasks that need to be performed as new versions of your application are
released. These tasks include QA and testing, as well as benchmarking.
Integration of the zSeries ported code into the regular build process for
the current release of the application as well as future releases should
also be planned. Additionally, long-term support of the zSeries platform
should be determined up-front and includes investment in training and education
for your staff, as well as the procurement of hardware and software resources.
You should consider this as an investment in the infrastructure --
in the systems and skills necessary to effectively support the zSeries
platform.

Tailoring
Along with the information provided regarding porting and infrastructure,
you will also want to consider the following which we call tailoring.
Customers usually like to have a familiar look and feel. This may
mean having the same application interfaces across all of the platforms
that it runs on, or it can mean tailoring part of the look and feel to
make it similar to other applications on zSeries servers. This is what we call
tailoring to zSeries.
