  3. The Problems / Challenges ➢ 80% 80% of the world’s corporate data still resides on mainframe systems today (H. Tessler, Enterprise Systems Media). Significant % of mainframe workloads are written in COBOL, PL/I or Assembler those languages. COBOL, PL/I or Assembler language – data layout defined in ➢ ➢ Monolithic system Monolithic systemwith decades of incremental enhancements. Highly risk averse Highly risk aversedue to mainframe workloads typically represent the most important enterprise systems (e.g. core banking systems) and cost sensitive. ➢ ➢ Skills shortage Skills shortagewith new generation IT professionals gravitated towards new technology (e.g. REST APIs and Java). ➢ Difficult to discover and integrate Difficult to discover and integrateexisting mainframe assets with the rest of enterprise systems.

  4. ZDT Overview • HCL Z Data Tools (ZDT) is a set of tools that help you to manipulate data stored on z/OS systems interactively and in batch processing. • Designed to deal with large production data efficiently while protecting integrity and privacy. • Access to z/OS data made simple by its intuitive and consistent user interface across a wide range of data stores available on the platform. • Access to data across multiple z/OS systems / LPARs made simple by its remote systems support. • A must have tool for every z/OS user including system programmers, application developers, ISPF users and much more. • Comprehensive support for a wide range of data store types: – Data Sets (VSAM, QSAM, PDS, PDSE, AIM, OAM) – DB2 – IMS – WebSphere MQ – CICS – Hierarchical File System under UNIX System Services Copyright © 2019 HCL Technologies Limited | www.hcltechsw.com Copyright © 2019 HCL Technologies Limited | www.hcltech.com 4

ZDT Advantages ZDT template repository for ZDT template repository for retaining mainframe knowledge retaining mainframe knowledge for the future for the future ZDT can provide a generic ZDT can provide a generic data access solution data access solution without programming without programming ZDT templates describe logical ZDT templates describe logical layout of data and allows layout of data and allows transformation without transformation without programming programming ZDT saves cost by ZDT saves cost by powerful set of tools powerful set of tools ISPF user friendly ISPF user friendly productivity productivity improvement features improvement features • A wide range of file types are supported out of box – no programming required. • Templates are created from COBOL, PL/I and Assembler COPYBOOKs or describe layouts in XML format. • Template repository contains a list of mapping between data source and matching template to use. • ZDT provides a powerful set of batch functions such as copy, compare, edit, export, load, print and much more. • Specify a group of resources to work with on a local system as well as remote systems. • ZDT enables manipulation of data interactively or in batch. • Describe most complex layout and data structures using the template’s criteria infrastructures. For example, segmented records, nested REDEFINEs and PL/I arrays. • This enables new users to start working with your mainframe data quicker. • ZDT’s remote systems support enables access to data on remote systems as well while hiding much of mainframe specific complexity. • Search text and change across the specified group of resources with powerful navigation panel display. • Once the repository is setup by expert, ZDT leverages the information during its operation to simplifies tasks for end users all around. • Change column orders and hide columns based on your requirements. • Clone the specified group of resources to create backup. • Replace in-house apps with powerful ZDT functions for improved efficiency & ease of maintenance. • Specify criteria to select a subset of data you are interested to work with. • Edit JCL with ease. 5 Copyright © 2019 HCL Technologies Limited | www.hcltechsw.com Copyright © 2019 HCL Technologies Limited | www.hcltech.com

  7. Mainframe Data Access Modernization Challenges Java™ on Mainframe Challenges  On z/OS® since 2000.  Most data stored on the platform are defined by COBOL, PL/I and Assembler programs.  IBM® z14 announcement: performance improvement by exploiting new hardware.  Mainframe data structures typically do NOT map directly to Java and other modern languages.  CICS® TS V5.4 announcement: Support for applications written to the Java™ EE 7 full platform specification.  Steep learning curve for non-mainframe developers to understand the structure and manipulate mainframe data.  IMS™ 15 announcement: More expansive and dynamic Java development experience.  New languages on the platform.  Offload MIPS to IBM z Integrated information Processor (zIIP) engine. {REST} Copyright © 2019 HCL Technologies Limited | www.hcltechsw.com Copyright © 2019 HCL Technologies Limited | www.hcltech.com 7

  8. ZDT APIs Overview  HCL Z Data Tools APIs (ZDT APIs) is an add-on product which provides Java™ and Swift application programming interfaces (APIs) to manipulate mainframe data. Mainframe Data (2) Binary data returned  APIs leverages ZDT’s template infrastructure to understand logical layout of mainframe binary data . 00101101 11001010 11000000 11000000 11110000 01010101 00000000 11010010 00110011 11001111 00000000 11010010 00110011 11001111 00000000 11010010 00110011 11001111 00101101 11001010 11000000 11000000 11110000 01010101 11000000 11000000 11110000 01010101 00101101 11001010  Mainframe binary data is converted into JSON format and returned to API consumers in Java or Swift for easier interpretation and manipulation for developers with no mainframe background. ZDT APIs (3) JSON formatted data is returned  Usage scenario includes but not limited to: (1) Data read request ▪ Replacement of legacy applications for batch processing of data in Java. ▪ Integration of traditional mainframe apps with new apps. Applications ▪ Interpretation of mainframe operational data for analytics (eg. SMF data). {REST} ▪ Manipulation of mainframe data in virtual storage.

  9. Use Cases for ZDT APIs Replacement of legacy applications for batch processing of data in Java Integration of traditional mainframe apps with new apps and data stores - Traditional mainframe data sources enabled via ZDT API for new or extended use cases, including reflecting data to other data platforms. IT Operation Analytics Manipulation of mainframe data in virtual storage Application Modernization - Interpretation of mainframe operational data for analytics (e.g SMF data). - For unusual resource types or manipulations - MIPS reduction (offload to speciality engines zIIP/ IFL’s) - ZDT backend allows for processing of ‘always online’ CICS resources - Develop new applications in Java™ and Swift Programming language - Build new business logic with JSON & RESTful API’s.
