2 Agenda Using ClearPath eportal to Modernize DPS Transactions Overview of ClearPath eportal Using DPS and CITA with eportal Using eportal Developer Data Source Projects Importing COBOL Source Orchestration Presentation Projects Staging an Application Modernizing a DPS Application Questions 2012 Unite Conference 05/15/2012 2

3 ClearPath eportal Application Modernization 2012 Unite Conference 05/15/2012 3

4 ClearPath eportal Major Components ClearPath eportal Developer Microsoft Visual Studio plug-in for building solutions No programming, point-and-click solution environment All integration components automatically generated Orchestration enables consolidation of transactions without code ClearPath web-based eportal Manager Manages applications and runtime environment Hardware configuration, application deployment, software upgrades, security, consolidated monitoring, etc. ClearPath eportal Runtime Platform Dedicated Specialty Engine for runtime deployment Performance optimized blades Personality Modules Black box design no user accessible components 2012 Unite Conference 05/15/2012 4

5 ClearPath eportal Case Study: U. S. General Services Administration (GSA) Challenge: Moving from green screens to a user-friendly graphical user interface (GUI) for applications that support Federal Asset Management functions, without requiring extensive, time-consuming and costly changes. Solution: The U.S. General Services Administration (GSA) employed Unisys ClearPath eportal Enterprise Solution, a specialty engine operating within the agency s secure ClearPath Libra environment, to web-enable key information transactions that resided in its green-screen application environment. The tool provides point-and-click development capabilities, which enabled GSA to modernize existing transactions and extend its applications to the Web with no back-end changes required Unite Conference 05/15/2012 5

6 ClearPath eportal Case Study: U. S. General Services Administration (GSA) Metrics: Maximize the value of existing applications through easy modernization Avoid a $9.9 million outlay of funds that would have been needed to support projected staffing requirements for new application development Eliminate a steep learning curve and rapidly deliver new capabilities using cutting-edge technologies, without disrupting current services Enhance ease-of-use for greater productivity and end-user satisfaction Flexibly support future mobile device demands as needed Download full GSA case study: Unite Conference 05/15/2012 6

10 Modernize DPS Transactions using ClearPath eportal Minimal/no code changes required to DPS transactions Passoff and Conversation-mode are supported Special connector working-storage defines the format of data used by ClearPath eportal Special connector terminal type (CONECTOR) determines how outgoing and incoming messages are processed Fields types that are not supported: B (Exact Binary) D (Double Precision) R (Real) Using D$GTSCN1/D$PTSCN instead of DPS Forms 2012 Unite Conference 05/15/

11 Working Storage Generation Working-storage generated for a DPS form that is tailored to work with eportal Resulting working-storage is imported using eportal Developer to define server messages 2012 Unite Conference 05/15/

12 Working-storage Format HEADER group contains metadata, and fields used to provide state information to a DPS program SYSTEM-FIELDS group contains data for systemdefined fields in a DPS form DATA group contains data for fields defined in a DPS form 2012 Unite Conference 05/15/

13 Required DPS/ePortal Integration Changes The following PLEs describe changes that must be applied to DPS 6R5 (CP 13.0) when using eportal: , , , , , , The following PLEs describe changes that must be applied to DPS 6R5A (CP 13.1), and DPS 6R5 (CP 13.0) when using eportal: , , , Unite Conference 05/15/

14 CITA Overview Communications Interface for Transaction Applications (CITA) provides an interface that allows access to OS 2200 TIP applications using a TCP/IP connection CITA uses MCB for input/output messages to/from a TIP application Use CITA Configuration to define: Port Number Application Group PID Pool DPS Terminal Type 2012 Unite Conference 05/15/

15 Example CITA Configuration In the above CITA configuration: the port number used to establish a new connection is 2800 the terminal type used to process incoming and outgoing messages is 129, which equates to the DPS terminal type named CONECTOR 2012 Unite Conference 05/15/

16 Suggested CITA Changes When Using eportal Allow DPS to recognize new connections so the terminal record can be initialized PLE: Applies to CITA 2R2A (CP 13.0) Add support for conversation mode in CITA PLE: Applies to CITA 2R2A (CP 13.0), and CITA 2R3 (CP 13.1) 2012 Unite Conference 05/15/

17 Using eportal Developer

18 eportal Developer: Data Source Projects Tailored to specific ClearPath data source Import COBOL record definitions to define server messages Define application/data flow using orchestration Can handle multiple presentation projects Smartphone Tablet Web Web Services 2012 Unite Conference 05/15/

19 eportal Developer: Importing COBOL Source Create server messages, and optionally create client messages from COBOL source Supports ACOB, and UCOB Supports special handling of DPS form working-storage Used to define discriminator fields for output server messages 2012 Unite Conference 05/15/

20 eportal Developer: eportal Message Window Used to manage Server and Client messages Create and modify client messages Used to drag and drop messages in application orchestration Predefined Server messages included in project template 2012 Unite Conference 05/15/

21 eportal Developer: Orchestration Defines how the application connects to and authenticates with a ClearPath server Event-driven handling of client messages Define message exchanges and data transformations 2012 Unite Conference 05/15/

22 eportal Developer: Presentation Projects Used to tailor the presentation to a particular type of device Traditional web browser Smartphone: iphone, Android, Blackberry, Tablet: ipad, Android, Blackberry, Used to create Web Service interface SOAP-based services RESTful Services 2012 Unite Conference 05/15/

23 eportal Developer: Stage eportal Application eportal applications staged to ClearPath server Supports staging of multiple versions of an application eportal Manager is used to deployed staged application to the eportal server Unite Conference 05/15/
