Manage Massive Data Growth with Online Repartitioning

Figure 1 — Original File or Table Structure (with N Partitions)

Situation   

One of the largest U.S. processors of credit card transactions provides 24×7 card management services on HPE NonStop Systems with HPE Shadowbase software in an active/active (partitioned) business continuity architecture (data collisions are not possible, Figure 1).

Problem

1. The processor’s database queries are starting to time out and are becoming very inefficient.
2. The growing database size and activity requires an online repartition (no application outage is allowed).
3. The repartitioning impact needs to be minimized for homogeneous (same) and heterogeneous (different) file formats and table schemas.
4. The processor required one tool and approach for all file and table types (Enscribe, SQL/MP, and SQL/MX).

Solution

• HPE Shadowbase Zero Downtime Migration (see slider below)
• Note:
  • The processor’s application is designed to close and re-open files/tables on command.
  • The slider below first shows repartitioning Enscribe files, and then SQL tables

Outcomes

• Enables dynamic online repartitioning, eliminating planned downtime and minimizing application impact (minimal to no application outage is needed)
• Supports online repartitioning of homogeneous and heterogeneous schemas and formats
• One solution for all file and table types (Enscribe, SQL/MP, and SQL/MX)
