Welcome to my site! After graduating in Computing in 1990, I accepted a position as a programmer at a Runcorn based software house specialising in electronic banking software, namely sp/ARCHITECT-BANK on Tandem Computers (now HPE NonStop). This was before the internet became more prevalent and so the notion of enabling desktop access to company accounts for inter-account transfers and book keeping was still quite a cutting edge idea (and smartphones only ever hinted at in Space 1999). The company was called The Software Partnership (which was taken over by Deluxe Data in 1994). I spent 5 years in Runcorn developing code for SP/ARCHITECT for various banks like TSB, Bank of Scotland, Rabobank and Girofon (Denmark) to name but a few. I then moved onto a software house in Salford Quays for further bank facing projects. After a further 23 years in the IT industry and now a Senior IT Project Manager (both Agile and Waterfall delivery), I thought I would echo out my Career Profile in this corner of the internet for quick and easy access.

HPE NonStop Tandem SQL/MP

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.

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, NonStop SQL 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.^[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.
