IMS 14 ICAL Control Data

5

IMS 14 ICAL Control Data

� User requirement– Allow an additional parameter in the application call list for the DL/I ICAL to pass control

data items to external clients– The control data area may contain any type of user-provided control data

� Business Value– Provide the flexibility for the ICAL user to pass additional information to external clients

in additional to the payload data

Requirement: SOAP Gateway user requirements for ICAL control data

� Support user-provided control data for IMS synchronous callout with SOAP Gateway– Customization of SOAP Gateway outbound message XML header

� Ability to inject installation-specific data into the header of outbound messages, e.g. Security Context, Logging Context, etc.

– Support of multiple endpoints� Different WSDL:PORT specifications in a single WSDL file, e.g. some are enabled for SSL and

some are not.

– Allow overrides of WSDL operations� Overrides destination in the WSDL and converter program name� Relieve the issue based on limited number of OTMA descriptors by allow overrides

– Flexible URL for callout out web services� Part of the URL can be based on runtime input values, for example:� hostname:port/xxx/services and hostname:port/yyy/services

IMS Mobile, API Management and Mobile/Cloud application

Mobile and API

8

74% of CIOs say mobile solutions are part of their vision for increasing competitiveness

Grow revenues…… While reducing overhead

“$7bn worth of items on eBay through APIs”Mark Carges (Ebay CTO)

The API which has easily 10 times more traffic then the website, has been really very important to us.”Biz Stone (Co-founder, Twitter)

“The adoption of Amazon’s Web services is currently driving more network activity then everything Amazon does through their traditional web sites.”Jeff Bar (Amazon evangelist) / Dion Hinchcliffe (Journalist)

API are self-discoverable services on the web that can be easily consumed by mobile and cloud applications.

Mobile and API

� How can I make my zSystems-based System of Records available for mobile consumption?

� How can I turn my enterprise system services as web APIs for new business opportunities?

� How can I manage and govern APIs with controlled access and charge back?

� How can I easily build a cloud or mobile application to consume enterprise web APIs in an open and standard way?

1. Enterprise Service and API enablement

IMS transactions as Enterprise Services

� Today, IMS transactions can be invoke as SOAP or REST services without IMS application change

– IMS transactions as SOAP services with Enterprise Suite SOAP Gateway– IMS also provides SOAP/REST capability with Websphere and Datapower– NEW: IMS transactions as REST services with z/OS Connect and IMS Mobile Feature Pack

IMS Mobile

� The IMS mobile strategy provides a strategic and dependable mobile foundation

� Expands IMS ecosystem via delivery of mobile infrastructure

� IMS Mobile Feature Pack (Enterprise Suite 3.1 GA June 2014)– Offer an integrated platform for full discovery, modeling, deployment and execution of

IMS transaction assets for mobile consumption– REST interface with JSON wire protocol– A singular approach for System z clients using WAS, CICS, IMS and DB2 using z/OS

Connect

IMS Mobile Feature Pack

� Enable mobile and cloud clients to access IMS transactions as REST/JSON services– Transform REST/JSON request to COBOL bytes and transform response back to JSON– No change to IMS applications

� Tooling: IMS Explorer for Development to easily create RESTful services from existing IMS transactions

� Runtime: Leverage z/OS Connect and WebSphere Application Server for z/OS Liberty Profile in two package offerings:

– IMS Mobile Feature Pack with embedded z/OS Connect and WAS Liberty Profile– IMS Mobile Feature Pack as a feature installable on top of existing WAS Liberty Profile

Once published, those services are hosted by IMS Mobile for discovery by mobile and cloud application developers

IBM API Management:“A Complete API Management Solution”

IBM API Management with z Systems services discovery

� IBM API Management provides custom registry function for discovering z Systems services

– SOAP services on IMS, etc…– REST services on z/OS Connect

� IMS and API Management– Discover existing IMS SOAP Gateway services

� APIM 3.0.1 or later� Enterprise Suite SOAP Gateway 3.1.0.3 or later� Enterprise Suite SOAP Gateway SOAP Service Technology Preview code

– Discover REST services on IMS Mobile Feature Pack and z/OS Connect� APIM 3.0.4 or later� Mobile Feature Pack with APAR PI34698

Define Service Registry in APIM

� Add SOAP Gateway or IMS Mobile Feature Pack as a custom registry in APIM

� Specify host, port and the context root of the service registry

� Test and save connection

� With the IMS Mobile or SOAP Gateway registry selected, discover services by clicking the search icon

� You can specify a text string to search for specific service. Or leave the search field blank to retrieve all services.

� Once the list of matching services returned, select check box for the desired service to create API.

2b. A list of service containing the search text “IMS” is returned

2c. Select the desired service to create API

2a. Specify text to search for specific service or leave blank for

all services Click icon to Search

Discover, search and add API for z System services

API for z System service is created

� A new API is created for the IMS SOAP or REST service. It is added to the list of APIs managed by APIM

� APIs can be published and make visible publicly for internal or external users

Autonomics

� …the essence of autonomic computing is system self-management, delivering better system behavior and freeing administrators from low-level task management.

� Autonomics– Automate the routine collection of data– Automate the simple analysis of this data– Automate the obvious decisions based off this analysis– Automate the straight-forward execution of decisions

� More Autonomics and additional capabilities will be covered in the Tools session
