Secure ATM Transaction Flow from Card Dip to Cash Dispense
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
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.
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:
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.
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.
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.
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]
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]
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.
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.
NonStop SQL is a commercial relational database management system that is designed for fault tolerance and scalability, currently offered by Hewlett Packard Enterprise. The latest version is SQL/MX 3.4.

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.
