Figure 1 — Original Architecture

Situation

A large and growing U.S. gas and convenience chain has over 3,500 stores, and is rapidly expanding. It uses Verifone (formerly AJB) point-of-sale and loyalty rewards applications on HPE NonStop systems using SQL/MX.

Most of the application runs in the OSS space, and it uses OSS Regular files for TX logs. The chain has future plans for continuous application availability.

Problem

No business continuity solution
SQL/MX tables and the OSS transaction log present backup challenges (e.g., data types and volume)

Solution

Use HPE Shadowbase Business Continuity (active/passive) for disaster recovery (DR)
Use HPE Shadowbase Essentials (SOLVUTIL) to create a backup copy of the OSS Log
Use HPE Shadowbase Compare to validate the BC data

Outcomes

Meets the minimum business continuity requirement checkbox with Disaster Recovery that can be verified
HPE Shadowbase software fully satisfies the chain’s needs across two file system types
- SQL/MX requires special processing to properly replicate (e.g., IDENTITY and SEQUENCE columns)
- OSS transaction log (flat files) produce massive data volumes
Strategically positions chain with a flexible replication engine for new architectures such as continuous availability
Allows for verification/validation of the business continuity data (both the SQL/MX data and the OSS Regular TX flat files) without taking an outage
