January 31, 2024 — Gravic Publishes Real-world Use Case Article on Avoiding Data Corruption

Gravic published a use case article, Real-world Use Case: Avoid Data Corruption by Switching from Passive Replication to Automated Failover and Recovery in the January/February issue of The Connection.

Recently, a customer called us and was concerned about “missing DR files.” After further investigation, the customer identified the cause: application failover did not include all of the customer’s applications.

• The customer replicates data in a uni-directional Active / Passive Post-Disaster Recovery configuration using two HPE NonStop systems.
• Every few months, the customer does failover testing. This architecture requires the customer to manually failover all of the required applications and switch replication in the opposite direction.
• For some reason, one of the customer’s applications was not properly configured to failover and process transactions in the reverse direction.

Please read our article and learn how we helped resolve this customer’s issue, setting them up with a better approach to avoid these fail-over faults in the future.
