CDB/Delta

CDB/Delta's architecture is centered around three primary components: the Delta Engine, the Control Server, and the Data Mover. The Delta Engine is the core component responsible for the actual data propagation and synchronization processes. ) and writes it to the target Db2 objects.

The Control Server acts as the central management point, handling task scheduling, configuration management, and monitoring. It coordinates the activities of the Delta Engine and provides a CLI for administrative tasks. The Data Mover is responsible for interacting with Db2, handling data retrieval and insertion operations.

These components communicate using TCP/IP. The CLI provides the primary interface for all operations. Configuration is stored in Db2.

The `PROPAGATE` command initiates data propagation, specifying source and target databases, and the data to be moved. The `SYNCHRONIZE` command ensures data consistency between databases. The `LOGPROCESS` command processes Db2 logs for data propagation.

Security is handled through integration with RACF or other security managers, providing authentication and role-based access control. Encryption is used for data in transit and at rest. Monitoring and logging are extensive, with detailed audit trails available for all operations.

CDB/Delta differentiates itself from competitors through its optimized use of image copies and logs for data propagation, providing superior performance. For example, the `STATUS` command provides real-time monitoring of data propagation tasks. The product's architecture is designed for high availability and scalability, supporting large-scale Db2 environments.
