First National Bank (FNB)

Achieving sub-second response for hundreds of millions of monthly transactions on the mainframe

The need:

The ubiquity and convenience of cellphones and tablets as computing devices represented a clear growth opportunity for FNB; in South Africa, more people have cellphones and smart mobile devices than bank accounts. FNB wanted to launch a reliable, secure and highly responsive mobile channel before its competitors, and looked for a platform that would enable very short time-to-market.

The solution:

FNB integrated a new Java-based mobile front-end directly with tried-and-trusted business logic and core banking services running on IBM® Information Management System (IMS™) on an IBM zEnterprise® EC12 server. IBM IMS Enterprise Suite Connect APIs for Java and C and IBM IMS Enterprise Suite SOAP Gateway manage links between the channel applications and core functionality and data on the mainframe.

The benefit:

� Rapid deployment enabled FNB to gain first-mover advantage in the market, gaining the number one spot for mobile banking

� Ultra-low average end-to-end response times of 30 milliseconds ensure snappy performance for mobile banking users

� Fast, secure and reliable mobile banking generates more business for FNB and reduces its average cost per transaction

“We don’t start from the premise that the mainframe is best; rather, we look at the requirements—big data, huge numbers of concurrent processes, high performance, high scalability, high security—and then look at what technology can deliver all of those things. The answer is IBM zEnterpriseand IMS.”

—Jay Prag, CIO – Hogan Channels, FNB

IMS Mobile Feature Pack

� IMS Mobile is a comprehensive solution with which clients can discover IMS

assets, model asset metadata, and enable and publish those assets as RESTful

services.

� Once published, those services are hosted by IMS Mobile for discovery by

mobile and cloud Application Developers.

� Associated tooling is delivered via IMS Explorer for Development.


The IMS Mobile Business

� Offers a comprehensive offering for different phases of your mobile

deployment

– IMS Mobile Feature Pack (via IMS Enterprise Suite 3.1.1 – GA June 13, 2014 )

• Deliver IMS applications and data to mobile and cloud developers in a secure,

governed, and optimized way via:

• An integrated platform that supports full discovery, modeling, enablement, and

deployment of both IMS transactions and IMS data

• A singular approach for System z clients using WAS, CICS, IMS, and DB2

– IMS TM Value Unit Edition (VUE) (and/or IMS DB VUE)

• Offers flexibility in managing costs of your workload growth via OTC pricing model

• IMS TM VUE and IMS DB VUE are included as the Mobile Workload Pricing (MWP)

Defining Programs – MWP announced May 6, 2014)


z/OS Connect

zOS Connect

A service that encapsulate calling z/OS target applications using REST calls. zOS Connect will support JSON payloads for calls from external cloud or mobile-based clients and will enable the conversion of the payload to the target program's expected format. It will also provide the response payload conversion from a byte array into JSON format before returning the response to the caller.

Connect to z/OS Connect

� Launch IMS Explorer for Development and make a connection to z/OS

Connect


Create an IMS connection profile

� Use IMS Explorer for Development to create an IMS connection profile. This

will define a connection between z/OS Connect and IMS Connect.


Create an IMS interaction properties profile

� Use IMS Explorer for Development to create an IMS interaction properties

profile. This this will be associated with a RESTful service to direct how the

service should interact with IMS.


Import IMS transaction message metadata

� IMS Explorer for Development imports COBOL or PL/I data structures that

represent IMS transaction’s input and output data format and deploys this

metadata to z/OS Connect.


Create and test the IMS RESTful Services

� Use IMS Explorer for Development to create an IMS RESTful Service by

binding your service definition to a transaction with message metadata, an

IMS interaction profile, and one or more connection profiles.
