MIGRATION



NEW DEVELOPMENT


© innoWake gmbh 2012 Portfolio innoWake 15

•  Natural application often business critical •  Removal of all SAG products within 3 to 18 months •  May encompass transition off Mainframe •  Risky big bang scenario •  Maintainability must be ensured •  Ongoing innovation in application •  Increase of flexibility

Initial Situation (comparable customer)


•  Low risk and manageable migration •  Transparency during migration •  High level of automation during migration •  Maintainability given in the future •  Presentation modern and independent of technology •  Architecture future-proof •  Reduction of dependency (platform, software, etc.) •  Cost reduction

Requirements for Migration

Syntax easy to understand: Natural to Java



Java-Implementation for •  Natural Statements (MOVE, COMPUTE, …) •  Natural data types (Arrays, Groups, Views, PE/MU, …) •  Language-flow (ESCAPE, REINPUT, …) •  Call structure (PERFORM, CALLNAT, FETCH, …) •  Interface (INPUT USING MAP, …) •  Output (DISPLAY, WRITE WORKFILE, …) •  Data access (FIND, READ, HISTOGRAM,…) •  Natural Parameters

Language Transformation


Syntax easy to understand: Cobol to Java


Cobol Syntax Java Syntax


Java Implementation for •  Cobol Statements (MOVE, UNSTRING, SET …) •  Cobol data types (PICA, PIC9 incl. all COMP Types, L88, etc.) •  Language-flow (CALL, PERFORM, …) •  CICS accesses (EXEC CICS SEND, RECEIVE, ABEND, etc.) •  Database accesses (EXEC SQL)

Language Transformation


•  Interfaces •  Changes of sources due to platform change •  Tape/data backup •  Print control •  Job control •  CALL – activating (Assembler, e.g.) •  Hyperdescriptors / phonetic descriptors

Project-Specifics Issues

Product-Portfolio maxenso



Holistic portfolio expansion opportunities


•  Customer requirements are the focus for innoWake •  Standard can not cover all individual needs •  Very flexible extensibility of Eclipse and the product-portfolio maxenso •  Creation of individual extensions with seamless integration into Eclipse

and maxenso

expert

Examples: •  service gen •  formatter

•  qs checker •  tidy up


Reference: Bank Vontobel AG, Zürich, Switzerland


Starting point: Natural-/Adabas-Application on z/OS

Goal: The goal was porting the application one-to-one including the entire screen flow. After migration everything needed to work precisely as it did before in Natural. In addition the migrated application has to be maintainable like before.

Task: •  Database-Migration to Oracle •  Change of operating system from Mainframe to unix •  Language-Migration from Natural to Java.

Volume: 3.300 objects, 40 GB data

Criticality: high: the application is core of the provided banking-services, therefore high demand to reliability and perfomance

Complexity: very high: language migration, database migration, EBCDIC-ASCII-conversion, and some more tasks because of mainframe removal (Job Management, Output Management)

Duration: 9 months

Migration financial application that controls and accounts for investments
