Who is z Systems Platform Test?

Integration Testing

Welcome to z Systems™ Platform Test, also known as Integration Test. The concept behind Integration Test is pretty simple: if two software products are going to run together on the same operating system platform, they have to be tested together with a focus on their interactions.

When you're working with an operating system such as z/OS or Linux, the testing is complex and important. Not only must all the elements and features of z/OS work together but we have to make sure z/OS works with a multitude of other products and functions.

Our Services

IBM i

We are the final verification of a z/OS release prior to its becoming generally available to customers. It ensures that all elements and features of z/OS work seamlessly together and can support true production, mission-critical work. It also must provide all the industrial-strength z/OS advantages you're depending on: reliability, availability, and serviceability.

We now use our blog to document any new testing experiences. For past test experiences, you can find them in our test reports.

Power Systems

We've set ourselves up to be as customer-like as possible. Our team members take on the roles of system programmers, operators, database administrators, and so on. We focus on providing availability of applications to end users, and we pay attention to service level agreements and performance objectives. We look at the recovery aspects and behavior of our systems from an end user's perspective.

Our goal, like yours, is to have our workloads up 24x7. We have workloads that exercise the sysplex, networking, and application enablement characteristics of our configuration.

data security

The primary focus of our team is to run a data sharing Parallel Sysplex on the z Systems platform in as much of a customer-like fashion as possible.

Our focus is on Parallel Sysplex functionality and data sharing, and on many other elements and features of z/OS, which are not all sysplex-oriented.

We strive to be both a customer and a test organization which helps us to better understand how challenging it is for you, to run multiple hardware and software products and make them all work together.

data security

In addition to the z/OS elements, the Linux team uses the following software in their day-to-day operations: z/VM, KVM on z Systems, Linux on z Systems, OpenStack, Ansible, WebSphere Application Server & Liberty, WebSphere Application Sever Network Deployment, DB2, Apache, Elastic Search, Logstash, Kibana, Spark & Hadoop, plus z Systems hardware cryptographic acceleration, and various other open source products

Here we provide you with additional information that we wanted to share in addition to our test reports.

We've organized the information into the following categories:

Coupling facility recovery

Encryption Facility

The IBM Encryption Facility for z/OS, from here on out referred to as Encryption Facility, provides encryption and decryption processing of data for exchange between different systems and platforms and for archiving purposes. The Encryption Facility consists of the following optional features:

A licensed Java™ reference program called Encryption Facility for z/OS Client is also downloadable from the Worldwide Web.

We tested various Encryption Facility functions including the following scenarios:

All of the JCL and shell scripts for the above 3 scenarios can be found on our Samples website.

Additional information on the Encryption Facility can be found in IBM Encryption Facility for z/OS: User's Guide (PDF, 923KB).

IBM Security Key Lifecycle Manager Offering for Tape and DASD Encryption

IBM Security Key Lifecycle Manager (ISKLM) Offering for Tape and DASD Encryption (PDF, 244KB) shows how we, z Systems™ Platform Evaluation Test, implemented and migrated to the new encryption key offering which supports key serving to tape and IBM disk storage devices.

Internal coupling facility (ICF)

Dynamic ICF expansion allows you to define a coupling facility partition to use a shared CP in combination with its dedicated ICF CPs when needed.

We also have a short chapter about the ICF in our December 1998 test report, and additional information is in Coupling Facility Configuration Options: A Positioning Paper (PDF, 719KB).

Server Time Protocol (STP)

The Server Time Protocol (STP) feature is designed to provide the capability for multiple servers and Coupling Facilities to maintain time synchronization with each other, without requiring a Sysplex Timer. This tip discusses our experiences associated with migrating to Server Time Protocol (STP) in the Poughkeepsie Development Lab, including:

Service Oriented Architecture (SOA)

The Mixed Platform Stack Project: Deploying a Secure SOA Solution into z/OS and Mixed z/OS and AIX Environments describes the experiences that IBM test teams encountered while creating, deploying, and testing a Service Oriented Architecture (SOA) solution using the IBM SOA suite of products on the z/OS platform and the z/OS platform in conjunction with distributed platforms.
