New DevelopmentLegacy Systems Challenges

• Flexible & fast business process adaptation is difficult with legacy systems.

• “Webifying” host applications is difficult using legacy development tools.

• Diverse development teams have poorly integrated tools & processes

• Educating and retraining legacy staff in new web technologies can be costly and time consuming

New Development

Typical Customer Pains with New Development• Development projects are costing too much and are

taking too long– Rewriting applications is costly and drives a poor

ROI on new projects– Unable to meet competitive initiatives because

development projects are too slow– Rewriting and modifying applications is slow and

error-prone– Maintenance costs are taking up too much of the

budget

• Skills imbalance– Multiple development environments limit ability to

use legacy programmers in new projects

– High education and training costs limit retraining of current staff

• New development increases risk– Unable to predict performanceof new applications– Unsure how to meet Service Level Agreements– Unable to meet peak loads on new applications

New Development

IBM Enterprise Modernization Combines New Development with Existing Systems to:

• Improve productivity and usability of legacy applications.

• Cost-effectively deliver existing applications to new groups of users using web technologies.

• Implement new business functions while protecting legacy investment.

• Leverage all enterprise skills.• Reduce education and training

costs.

Who are the Customers for Enterprise Modernization Solution?

ØCustomers who need to:üMove legacy applications and data to the web without

rewriting

üLower software deployment and maintenance costs

üStandardize on one infrastructure and development platform

üOffload call center workload and expense by making applications self-service

üProvide information on the Internet with 24 hour availability

Ø“Typical” customer profile for this pattern:üEnterprise Customers with existing COBOL and/or PL/1

applications, and CICS, IMS, or DB2 applications

üTheir current environments prohibit them from responding to change quickly and efficiently

üThey do not want to rewrite existing systems

CICS Transaction Gateway (CTG)CICS Transaction Gateway (CTG)

Ø Supports IBM Adapters & Connectors Strategy– Common tooling with other J2EE Connectors (J2C)– Packaged with WebSphere Studio Application Developer

Integration Edition (for development)

Ø CTG is a strategic connector from WebSphere to CICS– CTG is supported on 7 platforms– Can be run in local or remote mode with WebSphere– Can be deployed on mainframe or distributed platforms

Ø CTG supports a variety of AD tools and compilers– Primarily Java but also C, C++, COBOL, VB

Ø CTG will connect to a variety of CICS servers– TXSeries and CICS/VSE as well as CICS TS on OS/390

CTG Using J2C with ECI or EPI CTG Using J2C with ECI or EPI

Ø J2EE Connection Architecture (J2C) Adapters in conjunction with CICS Transaction Gateway (CTG) provide:– IBM strategic method of connectivity to CICS from WebSphere applications– Help integrate CICS application functionality into WebSphere applications

Ø CICS Transaction Gateway supports J2EE Connection (J2C) Adaptersfrom WebSphere to CICS using either:– CICS External Call Interface (ECI)– CICS External Presentation Interface (EPI)

Ø CICS External Call Interface (ECI) is:– Easier to use than the EPI interface– Requires COMMAREA interface into CICS applications (where presentation logic and

business logic are separated)

Ø CICS External Presentation Interface (EPI) is:– Used for connectivity with 3270 interface of CICS applications– Not as flexible and harder to use than ECI interface

Both ECI and EPI interfaces require much more development work than HATS – although both are more flexible than using HATS.

IBM WebSphere Host Integration OverviewIBM WebSphere Host Integration Overview

ØWhat It Provides (older news):ü A complete package for deploying 3270 and 5250 applications

both within and outside the Enterpriseü Standardized browser accessü Improved appearance and usability for green screen applicationsü Ability to webify legacy applications with no changes required on

host systemsü NOT an EHLLAPI type solution!


ØWhat It Provides (newer news):ü Strategic path for J2EE developmentü Using key IBM J2EE productsü Easier progression to J2EE for non-J2EE developersü Selectively customize parts of the application – no need to

customize the entire application from the startü Eliminates TN3270 port and traffic concerns with firewalls since

HATS uses HTTP and HTTPS through the firewall(s).
