HPE NonStop Spoolcom subsystem Spooler Command Language program Overview and Timeline

The HPE NonStop Spoolcom (Spooler Command Language) program is the administrative interface for managing the Spooler subsystem on HPE NonStop systems. It allows operators to configure, monitor, and control print jobs, collectors, and print processes. 

Program Summary

  • Purpose: Used to define and manage spooler objects such as collectors, devices, and jobs.
  • Key Functions: Starting/stopping the spooler, modifying device attributes, and controlling job states (e.g., hold, release, delete).
  • Architecture: Operates within the Guardian environment, communicating with the Spooler supervisor process to maintain 24/7 fault-tolerant printing operations. 

Historical Timeline by Era

1. The Tandem Era (1974–1997) 

  • 1976: Introduction of the Tandem NonStop system; basic spooling capabilities were essential for early OLTP (Online Transaction Processing).
  • 1980s: The Spooler evolved to handle complex routing and multiple collectors to support growing enterprise needs.
  • 1997: Spooler D41 released, providing stable management for the MIPS-based architecture. 

2. The Compaq & Early HP Era (1997–2014)

  • 1999–2000: Release of Spooler D46, enhancing device ownership and virtual device support.
  • 2001–2002: Spooler D48 released during the transition to the HP Integrity NonStop (Itanium) platform.
  • 2012: Major updates to Spooler D48 to support H01 and H02 RVUs, improving scalability for high-end systems. 

3. The Modern HPE Era (2014–Present)

  • 2014: NonStop X (x86-64) introduced. Spoolcom adapted to support the new architecture and virtualised environments.
  • 2018–2020: Focus shifted toward modernised interfaces. While Spoolcom remains the CLI standard, graphical alternatives like MultiBatch began gaining traction for batch management.
  • 2023–2024: Continued integration with HPE GreenLake and hybrid cloud models, ensuring spooling services are available in private cloud deployments. 

Futures and Roadmap

  • Modernisation: HPE is pushing toward “modernisation through tradition,” which includes better integration of legacy tools like Spoolcom with modern DevSecOps and cloud-native frameworks.
  • Kernel-Level Threading (KLT): Future updates aim to leverage KLT to improve the performance and scale-up capabilities of management processes.
  • Data-Centric Security: Integration with security platforms like TAMUNIO for field-level tokenization ensures that printed data remains compliant with PCI DSS 4.0 and GDPR.

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.
