Rocket® Data Replicate and Sync

Real-time, bidirectional data replication and synchronization from mainframe to cloud - powered by Rocket® DataEdge

What is Rocket Data Replicate and Sync?

Enterprise data replication software that uses Change Data Capture (CDC) to continuously synchronizes data between IBM Z, IBM i, analytics, cloud, and AI platforms in real time. Unlike batch ETL processes that move data only on a scheduled basis, RDRS continuously reads the database transaction logs and captures only the records that changed — delivering sub-second data freshness with near-zero impact on source system performance. 

RDRS connects IBM mainframe environments such as z/OS, Db2, VSAM, ADABAS with distributed, cloud, and streaming platforms including Kafka, MySQL, AWS, and Azure. It supports bidirectional replication and synchronization, meaning data changes flow in both directions, keeping all connected systems consistent without manual reconciliation. 

What’s blocking real-time data across your enterprise?

Organizations struggle to deliver current, trusted data to analytics, cloud, and AI platforms. Data modernization efforts stall because data remains fragmented across systems, difficult to integrate, or too costly to move at the speed the business requires. The most common blockers enterprises face when replicating mainframe data:

  • Mainframe CPU cost: Batch replication and on-mainframe processing drive up MIPS consumption as data volume grows. RDRS captures changes at the transaction-log level and offloads transformation, mapping, enrichment, and apply processing to lower cost platforms, reducing the mainframe resources required to deliver data to cloud, analytics, and AI platforms.  
  • Data latency: Scheduled ETL jobs create delays between operational systems and applications, dashboards, and AI models, leaving them to work with stale data. RDRS CDC continuously replicates changes as they occur, removing batch delays.
  • Platform incompatibility: Mainframe data sources like IBM Db2, VSAM, and IMS use data formats that cloud platforms cannot natively consume. RDRS includes an extensive code catalog for conversions and transformations that streamline integration across hybrid environments.
  • Replication fragility: Failed batch jobs and custom integrations can leave systems out of sync and require manual intervention to align. RDRS automated restart, rollback, and recovery capabilities maintain continuous data movement. 
  • Data silos across hybrid environments: Critical data is spread across mainframes, distributed systems, and cloud platforms, making it difficult to maintain a consistent view of operations. RDRS synchronizes data across these environments, providing a consistent foundation for analytics, operations, and AI initiatives.  
  • RDRS uses CDC to capture every data change at the transaction log level — no batch polling, no source query overhead, no missed deletes or rapid updates. 

  • RDRS supports bidirectional replication between IBM mainframe sources (z/OS, Db2, VSAM, ADABAS, z/VSE) and modern targets including Kafka, MySQL, AWS S3, Azure, and Google Cloud. 

  • RDRS reduces mainframe CPU costs by offloading data transformations to cloud compute, capturing once and applying to multiple targets simultaneously. 

  • Restartable pipelines, rollback controls, and integrity checks maintain uninterrupted data flow through system failures without manual intervention. 

  • Delivers data to AI and analytics platforms in real time so models and dashboards always reflect current state, not stale batch snapshots. 
     

Zero compromise on data integrity

Without complete, reliable, and current data, organizations struggle to make informed decisions, modernize applications, and build confidence in analytics and AI. RDRS creates a trusted data foundation by keeping information synchronized across mainframe, distributed, and cloud environments.

Maintain trusted data at scale

Preserve consistency across systems with centralized monitoring, validation, and synchronization controls that help teams identify issues quickly and maintain confidence in replicated data. 
 

Secure data end-to-end

Protect data in motion and at rest with encryption, secure connectivity, and access controls across mainframe, distributed, and cloud environments.

How does RDRS unify your enterprise data? 

RDRS captures data once and delivers it wherever the business needs it. By combining real-time CDC, integrated transformation, and one-to-many distribution, RDRS moves trusted data between mainframe, distributed, cloud, analytics, and streaming environments without creating duplicate integration pipelines. The result is faster data delivery, lower operational overhead, and a more connected enterprise.

Mainframe sources and targets

How RDRS delivers the real-time data that AI and analytics require

AI and machine learning models are only as accurate as the data they are trained and served on. When training data comes from mainframe systems via nightly batch ETL, models make inferences on data that is hours or days old — decisions are made using outdated information, reducing the effectiveness of fraud detection, personalization, operational automation, and other AI-driven business processes

RDRS eliminates this latency by streaming changes from mainframe sources directly to AI and analytics platforms as they happen: 

  • Real-time feature stores: Deliver current customer records, transaction data, and operational metrics to ML feature stores so models are trained and scored using the latest available information. 
  • Event-driven architectures: Stream mainframe changes to Kafka or Confluent so AI applications, automation workflows, and downstream systems can respond to business events as they occur.
  • Analytics freshness: Analytics dashboards reflect current business conditions, enabling decisions based on what is happening now rather than what happened during the last ETL cycle.
  • Zero disruption to production: CDC reads transaction logs rather than production databases, delivering real-time data without impacting mainframe performance or business operations.

Bring mainframe, cloud, and distributed data into sync

Accelerate your hybrid cloud data initiative with a real-time data replication and management solution built for enterprise-scale integration. RDRS supports the widest range of sources and targets, from IBM mainframe systems like z/OS®, z/VSE®, and ADABAS to distributed, cloud, and streaming platforms, maintaining data consistency, accessibility, and readiness across environments.
