Application Maintenance and Repurposing Code

IMS Transaction Efficiency

Designed and brought to market in the 1970's, IBM's IMS hierarchal database system software is used for processing and computation in high volume environments. IMS on the mainframe is known for its transaction efficiency and low cost per transaction. It remains well suited for applications that have structured data and access patterns that must scale to volume with high availability: ATMs, orders, claims, and assembly lines.

IMS DB system software provides a database environment which:

  • creates and manages data efficiently.
  • optimizes storage and retrieval.
  • ensures integrity and recovery.
  • implements security.
  • delivers excellent performance.
  • integrates with IBM WebSphere MQ middleware.

Although to a significant degree supplanted by IBM's DB2 and third party enterprise relational databases, there is an inventory of IMS applications and code which needs to be maintained and evaluated for repurposing as part of a SOA: service oriented architecture. In response to client usage and request, IBM continues to support IMS system software in order that advancements in mainframe hardware can be translated into improvements in price and performance through the leveraging of existing applications and data.

Rational Developer for System z is a IBM development platform to modernize software assets and deploy applications. It is used interactively to develop and test mainframe applications, low-level programming languages, and cross platform web technologies. Rational Developer for System z creates, maintains, and debugs IMS system-based code and SQL: Structured Query Language. Configuration files are created which enable an IMS SOAP Gateway to make web service calls to IMS transactions. Fault Analyzer integration is used to browse IMS abend reports.

IBM WebSphere MQ is the industry leading message queuing middleware platform. It is used in a SOA environment to route and transport messages among nodes and manage services in the enterprise. A message queuing infrastructure built upon and extended with WebSphere MQ is scalable and secure. Organizational enterprise with an investment in IMS applications are using IBM software and tools to evaluate the operational efficiency of its IMS software and develop a plan quantifying a return on investment.


IMS and SOA: Service Oriented Architecture

IMS assets contain business rules and billions of lines of legacy programming language code. Replacement of legacy code is economically unfeasible and results in loss of valuable business information. Within IMS mainframe installations, there is value in utilizing IMS assets and business logic in SOA modernization. IMS leverages running back-end processes and provides reliable integration points to support new business requirements. The modeling of business processes can be used to identify points of integration and interface. Efficient and reliable IMS applications can significantly lower risk, cost, and time to market. IMS can be extended using web services and connectivity for SOA. 

IMS_Application_Modernization

The IMS adapter connects a queue manager to IMS Transaction Server so that applications can use the MQI. The WebSphere MQ IMS bridge enables an application to run without an MQI. The application programs and the IMS adapter run in the same address space. The queue manager has its own address space. When a WebSphere MQ event occurs, the IMS CSQQTRMN trigger monitor initiates the IMS transaction.

LPAR: logical partition location determines the utilization of IMS Universal drivers: ODBA: Open Database Access or DRDA: Distributed Relational Database Architecture with IMS Connect. IMS Connect is the entry point for IBM DRDA. It is the TCP/IP gateway to IMS transactions, operations, and IMS data. IMS Open Database supports distributed TCP/IP access to IMS data both within an IMSplex or platforms other than System z.

EJB: Enterprise Java Bean components and JSP: Java Server Pages create web services with existing MFS-based IMS applications. New applications can be deployed to run on WebSphere Process Server.


SYS-ED IMS Training Service

SYS-ED staff has first generation experience with IMS: logical and physical design, application development, administration, and system programming. The orginal IMS curriculum was developed by technologist entrepreneurs and practitioners: Shaku Atre, Jonathan Clarke, Tina Connelly, Joan McInnes, Franz Schneider, and Karen Schwartz. Their database design, program logic, examples, case studies, exercises, and skeleton programs served as a foundation for the IMS courseware. If your organization outsourced its IMS coding and maintenance to consulting companies in the 1980ís, it more than likely was SYS-ED which trained the personnel who did the actual design and coding.

The SYS-ED IMS Transaction Server courses taught in conjunction with legacy programming languages and as part of mainframe training programs are a premium training service. Our staff reviews client documentation and interprets the system analysts and designers original work. SYS-ED trained IBM software developers evaluating Compuware's IMS File-AID which later became involved in the design of IBM Tools as an alternative to Compuware and other third party software - CA: InterTest, CA: Endevor, and Serena Software Changeman.

Given the scarcity of up to date IMS Transaction Server textbooks, SYS-ED has maintained its student handouts. With the hybrid implementation of open source software and IBM middleware, documentation is important to an effective learning experience. When information technology professionals complete a SYS-ED IMS course, they have the documentation and training aids to design, develop, and debug IMS applications.

SYS-ED receives training assignments and follow-up questions from system engineers with software companies: IMS control blocks, DL/1 coding, and architecture. Few software or consulting companies know IMS and teach better courses than SYS-ED.

Upon completion of a instructor-led course at the client location, it is standard policy to organize content for future utilization in a web-based training infrastructure.


Physical and Logical Database Design

The SYS-ED IMS curriculum incorporates customer experience and best practices in multiple fields: automotive, commuter rail transportation, financial services, public sector government services, healthcare providers, pharmaceutical companies, and telecommunications. In conjunction with qualifying IMS training assignments at client locations, SYS-ED staff and CETi technology partners participated in the review and application of the structured methodologies for logical and physical implementations of the IMS database.

Structured analysis is the use of data flow diagrams and data modeling inclusive of implementation-independent graphical notation of documentation.

Structured design is a systematic approach to programming which includes the use of graphical notation for documentation, communication, and design guidelines.

Structured programming techniques impose a logical structure on application development. Large routines are subdivided into smaller modular routines. Indentation is used to make loops and other program logic easier to follow. SYS-ED provided IMS training for Amtrak, Columbia Presbyterian Hospital, IMS Systems, State of Indiana, Johnson and Johnson Healthcare Systems, MCI Worldcom, McKesson Coporation, and United Parcel Service. There are installations where superb structured design and coding has IMS outperformed DB2.

The newer methodologies are associated with object oriented analysis and design; our staff also is experienced with these techniques and tools. This multi-generational skillset allows us to teach the modernization and repurposing of the IMS hierarchical database with WebSphere MQ middleware and Rational Developer for System z. We identify areas where inefficient processing is occurring and provide guidelines for developing applications with operational and diagnostic business intelligence. 

IBM's information agenda is built on its commercial operating systems and system software. Its foundation is to simplify, collaborate, reuse, and standardize. SYS-ED IMS Transaction Server courses and mainframe training programs augment the IBM information strategy: 1- Implement information-driven strategies consistent with business priorities. 2- Use unified tools to competitive advantage for managing data and designing reliable data structures. 3- Assess and when warranted deploy OSS: open source software to leverage existing information assets. 4- Accelerate the return on investment associated with information technology projects.


Courseware for Teaching

The courseware used in SYS-ED courses consists of student handouts, training aids, and industry-specific examples and exercises. The CETi knowledge base aggregates and analyzes information in the public domain. Content is added selectively to courseware. The long term strategy is to have our courseware recognized as a NRV: Nationally Recognized Vendor.

Grow Your Own IMS Programmers

There have been inquiries regarding whether SYS-ED still offered IMS courses for information technology professionals.

The typical comments were that:

1. It is extremely difficult to find IMS training which develops the specialized skills needed for application development and maintenance tasks.
2. There is a scarcity of IMS courses, 5 or fewer days in duration, geared to Fortune 1000 corporations and their employees.
3. A high percentage of IMS courses are cancelled.
4. Travel costs and living expenses in a majority of situations are a significant constraint when it comes to attending a IMS course.

In response to these questions:

IMS Training Services Yes, SYS-ED offers multiple levels of IMS training: Fundamentals, DB DL/1 Application Programming, and tailored courses.
IMS Training Services Yes, since 1980, SYS-ED has taught IMS programming courses and IMS training programs.
IMS Training Services Yes, we have the flexibility and resources to conduct personalized training for small groups.
IMS Training Services IMS courses are available in multiple formats: distance-learning, classroom instruction, and blended web-based delivery.

SYS-ED has been conducting courses in the public domain since 1980; however, there have been changes in the laws and regulations governing computer training in the state of New York. The schedule on our websites reflects a projected time frame for licensure with the New York State Department of Education - Bureau of Proprietary School Supervision and submission and approval of curriculum.


Professional Distance-learning Service

The distance-learning service is an extension of the SYS-ED schedule, inclusive of courseware and training aids. A distance-learning course is 65% lecture with pre and post course validation, review questions, examples, workshops, and website support services.

Teaching Models - Adult Learning Theory

Enrollment requires a consultation with the manager sending the employee for the training. The prospective trainee needs to be qualified for the course and service transmission to the client location tested: bandwidth, firewall, base operating system, software requirements, web browser, and set-up of hands-on machine exercises.

SYS-ED reserves the right to deny enrollment in its courses.


IMS Implementation, Application Development, and Administration

IBM has extended the software products used with IMS Transaction Server to model database schemas, streamline development, and improve system and database performance. The software integrates with IMS Tools for system resource and real-time database management. Interaction with IMS Tools previously had been through ISPF interfaces and JCL. The IBM Tools Base Administration Console can be used to design and deliver graphical user interfaces.
