Shadowbase DoLockStep (DLS) Brief

• 

Shadowbase DoLockStep (DLS) synchronizes application processing with data replication, helping ensure critical transactions and data are safely stored on a backup system before processing continues. By coordinating applications with replication activity, DLS reduces the risk of data loss during catastrophic failures, supports zero-data-loss strategies, and provides scalable, high-performance protection for mission-critical HPE Nonstop environments.

Key capabilities and benefits include:

• Allows an application to determine when all data generated up to a specific point has been successfully delivered and safe-stored on the target system before further processing proceeds.
• Is particularly valuable for applications that process high-value or mission-critical transactions, where it is important to know that replicated data is available on the backup system before continuing.
• Synchronizes application activity with replication status to help maintain consistency between source and target environments.
• Supports planned maintenance activities and failover operations.
• Reduces (and can eliminate) the risk of data loss that can occur when applications and replication processes operate independently.
• Differs from fully synchronous replication in that only the transactionally committed data created before the periodic API call is safe-stored at the target, rather than each transaction individually being safe-stored; this can lessen the latency impact of the synchronization process vs. fully synchronous Shadowbase ZDL replication.

Shadowbase DLS is exclusively included with the purchase of the Shadowbase Zero Data Loss solution.
