Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user’s job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

Liberty z/OS Connect

A service that encapsulate calling z/OS target applications using REST calls. zOSConnect will support JSON payloads for calls from external cloud or mobile-basedclients and will enable the conversion of the payload to the target program'sexpected format. It will also provide the response payload conversion from a bytearray into JSON format before returning the response to the caller.

IMS Transaction Navigator

From the IMS Gateway Navigator view, right click the Services folder and select “Create an IMS mobile transaction service”.

Create REST on mobile server

25

Give the service a name and click browse to select a transaction and the input and output message layouts you want.

26


27


Define the interface to the service by selecting the fields to include in the input and output messages (i.e. the mobile applications can only provide values for the included fields). provide any default values for either included or excluded fields. Excluded field default values cannot be overridden by the mobile applications.

28


On page 3 of the wizard you can type in remarks describing information about the service.

29


After clicking Finish you will see that the new service has been added to the IMS Gateway Navigator view.

30


31

Test the REST service

From the “Run a Test Case” window you can double click an input message field to change its value and then click the “Run” button to test.

32


Inspect the output message payload in the lower panel to ensure that the transaction was invoked and that it returned the expected output message.
