Company Website – Open Content Management Framework, DotNetNuke

In the early part of the millenium, ITL requested that I design and author a new company website using the Open Content
Management framework, DotNetNuke. This is a Visual Basic .NET Microsoft SQL database driven technology that enables website updates from any location with internet browser access.

As part of this exercise, website prominence was a key driver along with a more professional, corporate look-and-feel. The website is an ongoing programme of work that takes up a few hours a week of my time in taking it forward. I have attended 2 gbdirect (iTrain) website courses in this regard; ‘Writing for the Web’ and ‘Website Prominence and Visibility’. More information.

Base24-eps and UPF integration

Base24-eps and UPF integration

Integration between BASE24-eps and the Universal Payments Framework (UPF) is a core part of ACI Worldwide’s strategy to bridge legacy payment systems with modern, real-time payment capabilities. The UP Framework acts as a bridge, allowing financial institutions to orchestrate diverse payment types and channels while protecting their existing investment in BASE24-eps infrastructure. 

Key Aspects of the Integration

  • Investment Protection: The UP Framework allows existing BASE24 customers to continue using their current systems for some functions while incrementally adding new payment types and volumes through the UP Framework. This approach eliminates the need for a complete “rip and replace” of legacy systems.
  • Modernization and Flexibility: The integration with UPF allows banks to rapidly introduce new payment methods, adhere to new network schemes (like real-time payments), and integrate with new partners through configuration rather than custom coding.
  • Unified Retail Payments: UP Retail Payments is ACI’s comprehensive solution that combines the strengths of BASE24-eps (a market-leading retail payment platform) and the UP Framework (which orchestrates all aspects of payments processing) into a single, end-to-end platform.
  • Data Protection & Compliance: The UPF is used in conjunction with data security solutions (like Comforte’s SecurDPS) to tokenize sensitive cardholder data before it is passed to BASE24-eps applications or stored in logs, helping institutions meet PCI DSS compliance requirements.
  • Role-Based Expertise: The integration is an area of specialized technical expertise in the payment industry, with job roles focusing on the implementation, customization, configuration, and support of both BASE24-eps and UPF modules. 

In essence, the UPF provides a flexible, open architecture that extends the life and capabilities of BASE24-eps, enabling financial institutions to manage traditional and emerging payment demands within a unified ecosystem. 

What is BASE24-eps?

BASE24-eps is a comprehensive solution for acquiring, authenticating, routing, switching, and authorizing card- and non-card-based financial transactions through various channels.

BASE24-eps is designed to:

  • Increase the profitability of payment processing by enabling a set of common transaction services to support multiple channels and different types of transactions
  • Offer organizations greater flexibility with built-in support for all major card types, devices, national and regional switches, international payment schemes and host systems
  • Create a comprehensive view of customers and ensure consistent, high-quality customer service across different points of contact
  • Reduce organizations’ total cost of ownership through complete platform independence
  • Give organizations the options to deploy on premise, in their own private or public cloud, or in a secure, cloud-based environment managed by ACI

HPE NonStop previously Tandem Computers

NonStop is a series of server computers introduced to market in 1976 by Tandem Computers Incorporated,[1] beginning with the NonStop product line.[2] It was followed by the Tandem Integrity NonStop line of lock-step fault-tolerant computers, now defunct (not to be confused with the later and much different Hewlett-Packard Integrity product line extension). The original NonStop product line is currently offered by Hewlett Packard Enterprise since Hewlett-Packard Company’s split in 2015. Because NonStop systems are based on an integrated hardware/software stack, Tandem and later HPE also developed the NonStop OS operating system for them.

NonStop systems are, to an extent, self-healing. To circumvent single points of failure, they are equipped with almost all redundant components. When a mainline component fails, the system automatically falls back to the backup.

These systems can be used by banks, stock exchanges, payment applications, retail companies, energy and utility services, healthcare organizations, manufacturers, telecommunication providers, transportation, and other enterprises requiring extremely high uptime.

History

Originally introduced in 1976 by Tandem Computers Inc., the line was later owned by Compaq (from 1997), Hewlett-Packard Company (from 2003)[3] and Hewlett Packard Enterprise (since 2015). In 2005, the HP Integrity “NonStop i” (or TNS/E) servers, based on Intel Itanium microprocessors, was introduced. In 2014, the first “NonStop X” (or TNS/X) systems, based on Intel x86-64 processors, were introduced. Sales of the Itanium-based systems ended in July 2020.[4]

Early NonStop applications had to be specifically coded for fault tolerance. That requirement was removed in 1983 with the introduction of the Transaction Monitoring Facility (TMF), along with Pathway transaction management software and SCOBOL applications (or, later, NonStop Tuxedo transaction management software), which handles the various aspects of fault tolerance on the system level.

Software

NonStop OS is a message-based operating system designed for fault tolerance. It works with process pairs and ensures that backup processes on redundant CPUs take over in case of a process or CPU failure. Data integrity is maintained during those takeovers; no transactions or data are lost or corrupted.

The operating system as a whole is branded NonStop OS and includes the Guardian layer, which is a low-level component of the operating system and the Open System Services (OSS) personality which runs atop this layer, which implements a Unix-like interface for other components of the OS to use.

The operating system and application are both designed to support the fault tolerant hardware. The operating system continually monitors the status of all components, switching control as necessary to maintain operations. There are also features designed into the software that allow programs to be written as continuously available programs. That is accomplished using a pair of processes where one process performs all the primary processing and the other serves as a “hot backup”, receiving updates to data whenever the primary reaches a critical point in processing. Should the primary stop, the backup steps in to resume execution using the current transaction.[5]

The systems support relational database management systems like NonStop SQL and hierarchical databases such as Enscribe.

Languages supported include Java,[6] C, C++,[6] COBOL, SCOBOL (Screen COBOL), Transaction Application Language (TAL), etc. It uses the scripting and job control language TACL (Tandem Advanced Command Language), and is written in TAL and C.

Hardware

The HPE Integrity NonStop computers are a line of fault-tolerant, message-based server computers based on the Intel Xeon processor platform,[4] and optimized for transaction processing. Average availability levels of 99.999% have been observed.[7] NonStop systems feature a massively parallel processing (MPP) architecture and provide linear scalability. Each CPU runs its own copy of the OS, and systems can be expanded up to over 4000 CPUs. This is a shared-nothing architecture—a “share nothing” arrangement also known as loosely coupled multiprocessing.

Due to the integrated hardware/software stack and a single system image for even the largest configurations, system management requirements for NonStop systems are rather low. In most deployments there is just a single production server, not a complex server farm.

Most customers also have a backup server in a remote location for IT disaster recovery. There are standard products to keep the data of the production and the backup server in sync, for example, HPE’s Remote Database Facility (RDF),[8] hence there is fast takeover and little to no data loss also in a disaster situation with the production server being disabled or destroyed.

HP also developed a data warehouse and business intelligence server line, HP Neoview, based on the NonStop line. It acted as a database server, providing NonStop OS and NonStop SQL, but lacked the transaction processing functionality of the original NonStop systems. The line was retired, and no longer marketed, as of 24 January 2011.[9]

HPE NonStop Tandem Enscribe Database

Enscribe is the native hierarchical database in the commercial HP NonStop (Tandem) servers. It is designed for fault tolerance and scalability and is currently offered by Hewlett Packard Enterprise.

The product was originally developed by Tandem Computers. Tandem was acquired by Compaq in 1997. Compaq was later acquired by Hewlett-Packard in 2002. When Hewlett-Packard split in 2015 into HP Inc. and Hewlett Packard Enterprise, Enscribe and the rest of the NonStop product line went to Hewlett Packard Enterprise.

The product primarily is used for online transaction processing and is tailored for organizations that need high availability and scalability for their database system. Typical users of the product are stock exchanges, telecommunications, POS, and bank ATM networks.

Somewhat similar to Record Management Services on OpenVMS platforms, some Enscribe features are:[1]

  • Five disk file structures: unstructured, key-sequenced, queue, entry-sequenced, and relative
  • Partitioned (multiple-volume) files
  • Multiple-key access to records
  • Relational access among files (where a field value from one file is used as a key to access a data record in another file)
  • Optional automatic maintenance of all keys
  • Optional key compression in key-sequenced data or index blocks
  • Support of transaction auditing through the Transaction Management Facility (TMF/MP). TMF is the main functional component of the NonStop Transaction Manager/MP product.
  • Optional compression of audit-checkpoint records
  • Record level locking and file level locking
  • Cache buffering
  • Optional sequential block buffering
  • Waited and Nowaited I/Os (multi-threading of I/O calls by the programmer)[2]

The NonStop OS Guardian APIs or the utility FUP (File Utility Program) can be used to work with Enscribe files.

A “convert” utility was provided by Tandem to aid in converting Enscribe files to NonStop SQL files, when desired.[3]

Many of the applications developed in HP NonStop servers (often critical ones) run on Enscribe databases.

History

Enscribe is designed to run effectively on parallel computers, adding functionality for distributed data, distributed execution, and distributed transactions.

First released in the early 1980s, and initially carrying an added charge until it was included with the operating system, the product became one of the few hierarchical data base systems that scales almost linearly with the number of processors in the machine: adding a second CPU to an existing server almost exactly doubled its performance.

The product primarily is used for online transaction processing and is tailored for organizations that need high availability and scalability for their database system. Typical users of the product are stock exchanges, telecommunications, POS, and bank ATM networks.[1]

History

NonStop SQL is designed to run effectively on parallel computers, adding functionality for distributed data, distributed execution, and distributed transactions.

First released in 1987, a second version in 1989[2] added the ability to run queries in parallel, and the product became fairly famous for being one of the few systems that scales almost linearly with the number of processors in the machine: adding a second CPU to an existing NonStop SQL server almost exactly doubled its performance.

The second version added /MP to its name, for Massively Parallel. A third version, NonStop SQL/MX, created a product that was more ANSI SQL compliant than its predecessor. NonStop SQL/MX has shipped on the NonStop platform since 2002, and can access tables created by NonStop SQL/MP, although only “Native SQL/MX tables” offer ANSI compliance and many “Oracle-like” enhancements. The HP Neoview business intelligence platform was built using NonStop SQL as its origins. NonStop SQL/MX is HP’s only OLTP database product.

Parts of the Neoview code base were open sourced in 2014 under the name Trafodion, which is now a top-level Apache project.

COBOL85 programming language on HPE NonStop systems (formerly Tandem NonStop)

“COBOL85 nonstop” refers to the use of the COBOL85 programming language on HPE NonStop systems (formerly Tandem NonStop). The HPE NonStop platform is known for its fault-tolerant, continuous availability architecture, often used for critical, large-scale transaction processing. 

Key aspects of COBOL85 on NonStop include:

  • Platform-Specific Implementation: HPE provided a specific implementation of the 1985 COBOL standard tailored to its unique Guardian operating system and hardware architecture.
  • Mission-Critical Applications: COBOL programs on NonStop are commonly used in industries such as finance, retail, and government for applications requiring high reliability and constant uptime (the “nonstop” nature of the system).
  • Fault Tolerance: NonStop systems achieve fault tolerance through mechanisms like process pairs, and the COBOL runtime library can interact with these features. For example, a PARAM NONSTOP OFF setting in a PATHMON configuration can prevent a COBOL85 server from running as a process pair if that behavior is not desired.
  • System Integration: Programmers can call Guardian procedures and use embedded SQL/MP statements within their COBOL85 programs to interact with the system’s robust file system and database.
  • Development and Maintenance: The combination of COBOL85 and HPE NonStop utilities is a specific skill set for developers maintaining these critical legacy systems.
  • Tools and Manuals: Documentation and tools, such as the INSPECT symbolic debugger and the FUP (File Utility Program), are specific to the NonStop environment and assist with development and maintenance. 

For detailed information, users can consult the official documentation, such as the HP COBOL Manual for TNS and TNS/R Programs or other manuals available on the NonStopTools website and HPE Support portals.
