A single delayed transaction on an HPE NonStop system rarely stays contained. It cascades — one alert triggers the next, and the team chasing the noise ends up further from the actual cause, not closer to it.
Prognosis for HPE NonStop gives you visibility into the subsystems that keep high-volume Online Transaction Processing (OLTP) environments running: Transaction Management Facility (TMF) and AutoTMF, plus the Remote Database Facility (RDF) that underpins disaster recovery and business continuity. You spot the pattern before it becomes an outage, and keep replication and failover costs under control at the same time.
TMF, AutoTMF and RDF failures don't stay isolated — they take the applications built on top of them down too.
TMF, AutoTMF and RDF subsystems handle high-volume transaction processing on HPE NonStop. When any one of their components degrades or fails, the applications depending on them — and the business continuity commitments built around them — are exposed.
Prognosis identifies and tunes these components, and manages the events that affect throughput, data replication and performance. Built from decades of monitoring real-world HPE NonStop environments, it's designed to surface problems early, before they reach users or customers.
One delayed transaction can trigger a chain of alerts — Prognosis gets you to the actual cause, not just the symptoms.
Real-time monitoring combined with historical data capture and reporting improves system performance and reliability over time. A delay in one transaction can set off a chain reaction, with each new alert further from the actual cause than the last. Prognosis's drill-down capability identifies the source quickly, then routes it to the people who need to fix it — through email, SNMP traps and mobile notification, backed by automation and availability management. Prognosis also provides transaction identification for Pathway environments, and integrates with common enterprise management frameworks.
Long-running transactions eat into audit trail capacity — and can stop new transactions from starting.
Prognosis verifies that transactions can execute by monitoring TMF and AutoTMF components and reporting abnormal events or performance indicators, including long transactions that affect audit trail capacity and block new transactions from starting.
Prognosis detects degraded conditions early and raises alerts you can act on: view every element involved, follow the diagnostic path, and resolve the issue — or let Prognosis apply a predefined action path for common problems, running inside Prognosis's own security model. Prognosis also tracks hung transactions, transaction rates and the other factors that determine OLTP application health.
The gap between extractor, receiver and updater processes is what determines how fast you can fail over.
Prognosis monitors the availability of every process, volume and data flow in the RDF subsystem, plus the communication links between primary and backup systems, so you're ready for failover or disaster recovery when it counts. Real-time notification and alerting shorten response times under pressure, helping you optimize replication performance and control the cost of maintaining business continuity. Time delays between extractor, receiver and updater processes are tracked continuously, so failover stays fast and predictable.
What is TMF on HPE NonStop?
Transaction Management Facility (TMF) is the HPE NonStop subsystem that manages transaction integrity for OLTP applications, tracking audit trails and ensuring transactions complete correctly.
What's the difference between TMF and AutoTMF?
AutoTMF automates the management of audit trails within TMF, reducing the manual overhead of monitoring and maintaining transaction audit capacity.
What does RDF do on HPE NonStop?
Remote Database Facility (RDF) replicates data between primary and backup HPE NonStop systems, underpinning disaster recovery and business continuity.
Why does long-running transaction monitoring matter?
Long transactions consume audit trail capacity. Left unchecked, they can prevent new transactions from starting, stalling the whole application.
