  • 13347 CICS Introduction and Overview
    CICS Introduction and Overview Ezriel Gross Circle Software Incorporated August 13th, 2013 (Tue) 4:30pm – 5:30pm Session 13347 Agenda What is CICS and Who Uses It Pseudo Conversational Programming CICS Application Services CICS Connectivity CICS Resource Definitions CICS Supplied Transactions CICS Web Services CICS The Product What is CICS? CICS is an online transaction processing system. Middleware between the operating system and business applications. Manages the user interface. Retrieves and modifies data. Handles the communication. CICS Customers Banks Mortgage Account Reconciliations Payroll Brokerage Houses Stock Trading Trade Clearing Human Resources Insurance Companies Policy Administration Accounts Receivables Claims Processing Batch Versus Online Programs The two ways to process input are batch and online. Batch requests are saved then processed sequentially. After all requests are processed the results are transmitted. Used for order entry processing such as warehouse applications. Online requests are received randomly and processed immediately. Results are transmitted as soon as they are available. Response time tends to be sub-second. Used for applications – such as: Credit Card Authorization. Transaction Processing Requirements Large volume of business transactions to be rapidly and accurately processed Multiple users, single/sysplex or distributed With potentially: – A huge number of users – Simultaneous access to data – A large volume of data residing in multiple database types – Intense security and data integrity controls necessary The access to the data is such that: – Each user has the perception of being the sole user of the system – A set of changes is guaranteed to be logically consistent. If a failure occurs, any intermediate results are undone before the system becomes available again – A completed set of changes is immediately visible to other users A Business Transaction A transaction has a 4-character id.

  • Introduction-To-Mainframes.Pdf
    Mainframe The term ‘MainFrame’ brings to mind a giant room of electronic parts that is a computer, referring to the original CPU cabinet in a computer of the mid-1960’s. Today, Mainframe refers to a class of ultra-reliable large and medium-scale servers designed for carrier-class and enterprise-class systems operations. Mainframes are costly, due to the support of symmetric multiprocessing (SMP) and dozens of central processors existing within in a single system. Mainframes are highly scalable. Through the addition of clusters, high-speed caches and volumes of memory, they connect to terabyte holding data subsystems. Mainframe computer Mainframe is a very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. In the hierarchy that starts with a simple microprocessor at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe. The distinction between small mainframes and minicomputers is vague, depending really on how the manufacturer wants to market its machines. Modern mainframe computers have abilities not so much defined by their single task computational speed (usually defined as MIPS — Millions of Instructions Per Second) as by their redundant internal engineering and resulting high reliability and security, extensive input-output facilities, strict backward compatibility with older software, and high utilization rates to support massive throughput. These machines often run for years without interruption, with repairs and hardware upgrades taking place during normal operation.

  • Appendix A: Current Environment Overview the Following Subsections Provide an Overview of the Current Technical Environment
    1 Appendix A: Current Environment Overview The following subsections provide an overview of the current technical environment. N-FOCUS – Nebraska’s Legacy Integrated Health and Human Services and Benefits Application Nebraska Family Online Client User System (N-FOCUS) is an integrated system that automates benefit/service delivery and case management for more than 30 DHHS programs, including Aid to Dependent Children (ADC), Supplemental Nutrition Assistance Program (SNAP), Child Welfare and Medicaid. The system was initially developed in partnership with Accenture as the prime Systems Integrator. N-FOCUS functions include client/case intake, eligibility determination, case management, service authorization, benefit payments, claims processing and payments, provider contract management, interfacing with other private, state and federal organizations, and management and government reporting. N-FOCUS was implemented in production in mid-1996 and is operational statewide. The typical N-FOCUS user is a DHHS or contracted employee. N-FOCUS supports over 2500 workers, operating from offices around the State as well as from 4 customer service centers and a centralized scanning facility. Some cases are assigned to specific workers; however, the majority of cases are managed via a universal caseload methodology coordinated by the customer service centers. N-FOCUS has both batch and online components and stores data in Db2 and SQL Server. The Db2 database has over 650 tables, some with a corresponding archive table. There are over 785 relationships between tables, 1278 indexes, and over 9665 attributes. There are over 1.7 billion rows of production data with over 193 million rows in one table with an average table size of 3.2 million rows.

  • Writing a Web-Enabled CICS/COBOL Program SHARE March 2011
    User Experience: Writing a web-enabled CICS/COBOL program SHARE March 2011 Craig Schneiderwent State of Wisconsin Department of Transportation [email protected] #include <std/disclaimer.h> 1 Any opinions expressed are my own and do not necessarily reflect those of my employer. You wouldn’t believe the amount of red tape that one statement gets me out of. What You Will See • Web-enabled CICS/COBOL code (CICS Web Support as opposed to Services) • Other cool, webby stuff – COBOL to generate XML – COBOL to parse XML • The COBOL is just snippets, an entire working application is available on the SHARE website with the materials for this session 2 This presentation grew out of a proof of concept application I wrote to help out our development staff. Please note the bit about CICS Web Support vs. CICS Web Services. The former is what I’m going to talk about, the latter is the more formal SOAP and WSDL stuff. Many people think these cannot coexist, they can. Many people think the latter supersedes the former, it does not. Both have their uses, both have their place, both have their adherents to varying degrees of zealotry. The proof of concept application receives parameters and based on those will send HTML, XML, an HTML form, or an image from CICS back to the requesting web browser. Main entry point in the application is J7200544. Environment (at the Time) • z/OS 1.6, CICS TS 2.2, DB2 7.1, Enterprise COBOL 3.4 • WebSphere Application Server (WAS) 5.x on Windows • 20 years worth of CASE tool generated business logic in CICS • CASE tool runtime uses CICS COMMAREAs to pass data out of CICS 3 Since then we've been migrated to WAS 6, z/OS 1.11, DB2 v8, and CICS TS 3.2.
