ONE AGILE MIDDLEWARE MULTIPLE APPLICATIONS

Virtel Web Access – Thin-Client 3270 TE Serve 3270 application screens to thin-client web browsers

Virtel Web Modernization – Web Portals (GUI/WUI) Serve 3270 screens as user-friendly web pages that provide a

genuine web experience

Virtel Web Integration – App-to-App Connector Create interactive bidirectional application-to-application

connections over the Internet:

Web services: SOAP, RESTful, XML, JSON, MQ …

Replace SNA (3745, HIS …) with IP connections

Legacy TN3270 Architecture

3270 emulation uses either a thick-client architecture or one based on middle-tier servers

12

Virtel PureWeb™ Technology Key Features and Benefits (1/2)

+ 100% host-based installation and support

+ Thin-client: nothing to install or support on clients

+ Two-tier: no middleware or intermediate servers

+ Requires no modification of application code or TS, and can coexist with any other connector

☺Very simple installation-deployment-support

☺Universal compatibility: Windows 7, 64-bits, Linux, Unix, Mac, Smartphones, PDAs, tablets, etc

☺Low risk: no impact on host applications and TS

Safer than TN3270

IP security:

PROXY, SSL, SSO, VPN, etc

Uses AT-TLS protocol for HTTPS (SSL encryption)

Mainframe security:

Standard TCP/IP port: no need to open special port in host’s firewall as with TN3270

Reuses RACF-TSS-ACF2 application access control rules to control web access to mainframe

Client security:

No data stored on client no exposure if client lost/stolen

VIRTEL Web Modernization – Highlights

Web portals (GUI/WUI) for 3270 apps: Reduce data entry errors

Reduce training for new/temp staff

Self-service by clients and BPs

Integrate host apps to existing WUI/GUI

Reach consumer/mobile devices

Replace IBM-HATS, screen-scrappers …

No application change

Fast and agile development

create GUI from 3270 screens

different concurrent layouts

VIRTEL Web Integration – Highlights

Interactive bidirectional app-to-app connections:

New (or replacement) web services

Application interoperability

Outdated connectors: SNA/3745 …

Cloud integration

Single European Payment Area

No application change

Fast and agile development

Great for “hard stuff”

Virtel IMS Extender

Easy integration of Web Services from IMS applications

© 2012

A composite IS

Modern IS are heterogeneous

Mainframe

Unix/Linux

Windows

Cloud

Applications need to communicate

Mainframe applications are critical

Applications need a common language (protocol, format)

© 2012

The mainframe legacy

Mainframe applications

Are evolving (time to market, regulation,…)

Are not monolithic

Need to integrate external data sources, applications, services

Integrating external services

Dealing with XML content is hard

Dealing with protocol (HTTP,…) is also hard

© 2012

Calling outside

Monitor based applications Impose constraints

Outgoing TCP calls may block the monitor

Solution must respect the architecture

Solutions IMS has implemented ICAL API

Virtel is a good IMS citizen

Virtel IMS connector implements RESUME/TPIPE through IMSConnect

Virtel services may be called from any IMS application through ICAL

Synchronous call from application point of view

IMS internal queue is used for exchanging messages

Virtel IMS integration

Virtel issues RESUME/TPIPE using IMS Connect

Application send an input message to Virtel using ICALL

The input message is processed by a Virtel scenario which respond an output message

Output message is returned transparently to the IMS application

Use case: external web service

From the IMS point of view

XML payload converted to COBOL copybooks

Virtel scenario performing the conversion

Calling the service: Filling a COPY-BOOK (routing information + user data)

Performing an ICALL call returning the output copybook

All artifacts are generated by Virtel Studio Scenario

Input and output copybooks

Virtel Studio

Virtel Studio is used for

Managing XML to COBOL mapping: Strings needs to be sized (a default one is provided) -> PIC X

Arrays needs to be sized (a default one is provided) -> OCCURS

Once mapping has been tuned, Virtel Studio will: Generates the scenario and input and output copybooks

From Virtel Studio, upload the generated scenario to Virtel and copy the generated copybooks to the IMS development environment and modify the IMS application
