DARSTRAN Oracle Logminer

The architecture of DARSTRAN Oracle Logminer is designed for efficient and reliable data replication. The core components include the Logminer Reader, Transformation Engine, Target Writer, and Control Center. The Logminer Reader is responsible for extracting data from the Oracle redo logs.

It uses Oracle's LogMiner API to access the redo logs and capture data changes. The Transformation Engine processes the extracted data, applying user-defined transformation rules. These rules are defined in configuration files and can include data type conversions, filtering, and data enrichment.

The Target Writer loads the transformed data into the target database. It uses database-specific APIs to insert, update, and delete data in the target tables. The Control Center provides a centralized management interface.

It allows administrators to configure replication jobs, monitor replication status, and manage error handling. The Control Center also provides access to CLI tools for automation. Communication between components occurs over TCP/IP.

For z/OS targets, WebSphere MQ is used for reliable message queuing. The system supports database-specific authentication methods. The design emphasizes high availability and fault tolerance, with features such as automatic failover and error handling.

The product's architecture supports a wide range of target databases and provides flexibility in data transformation and replication.
