Transform Inflight Data Using Shadowbase Mapping

Situation

A large European financial service provider offers trading and payment services for over 100 member banks on HPE NonStop systems. The provider’s development team follows agile procedures in releasing new core application functionality every three to six months in response to an energetic market.

The team started to plan for its next release (“day D-180”), which included a platform refresh using an existing replication engine.

Problem

1. The existing replication engine’s availability on the new platform was delayed, and its license costs were spiraling out of control, causing the provider to look for alternatives.
2. The provider could not take an extended application outage when performing the platform refresh and delivering future releases.
3. To reduce downtime for the migration, the data needed to be transformed and loaded into the new formats in parallel with existing processing.
4. The provider needed to validate the entire process before migrating /committing to the new environment.

Solution

• Use HPE Shadowbase Zero Downtime Migration (ZDM) to perform the platform and application refresh as part of a business continuity environment
• Use HPE Shadowbase Essentials (SBMAP) to transform operational data in-flight
• Use HPE Shadowbase Compare to validate the new vs old data

Figure 1 — SBMAP Integrates with Shadowbase to Receive the Source Data/Data Changes, Perform the In-flight Transformations, and Return the Transformed Data so it is Written to the Target in the Proper Format

Outcomes

• Enables the product development team to seamlessly upgrade its application
• Creates a template the team will use for future releases
• Transforms the source SQL table schemas and data in-flight into their target schema equivalents during the refresh
• Allows the new environment to be fully data-validated before the switchover occurs
• Replaces the original replication engine and saves significant license costs
