OpenLogReplicator: the new integrated connector for Oracle CDC

A revolutionary approach to Oracle Change Data Capture

Managing Change Data Capture (CDC) for Oracle databases has traditionally required complex configurations, additional licenses and reliance on tools like LogMiner or XStream. Gluesync simplifies and automates this process through OpenLogReplicator, a fully integrated connector.

We built this new connector on the open-source OpenLogReplicator library. Thus, it enables direct access to Oracle redo logs and archive logs without requiring additional Oracle licenses. Unlike traditional approaches, OpenLogReplicator eliminates the need for LogMiner or XStream, making data replication faster, more secure and easier to manage.

Fully integrated and autonomous operation

One of the standout features of OpenLogReplicator is its seamless integration within the Gluesync agent. Users don’t need to configure or manage it manually—everything runs autonomously within the same Docker container as the agent.

This integrated approach offers several key benefits:

• zero manual configuration: the component is pre-installed and automatically managed by Gluesync.
• enhanced security: archive log data never leaves the container, preventing unauthorized access.
• no need for external tools: unlike traditional CDC solutions, OpenLogReplicator works without LogMiner or XStream, reducing Oracle dependency.

With this plug-and-play functionality, enterprises can focus on their data pipelines instead of troubleshooting configurations.

How does OpenLogReplicator access transaction logs?

To efficiently capture INSERT, UPDATE, and DELETE operations, the Oracle OpenLogReplicator agent reads transactions directly from redo log files. To enable this, it supports multiple access methods, including:

• NFS (Network File System): allows redo logs to be accessed over a shared network, ensuring stable and high-performance data retrieval.
• SSHFS (SSH File System): provides secure access to redo logs via SSH, making it well-suited for distributed environments or those with strict security policies.

By leveraging these methods, OpenLogReplicator ensures seamless CDC operation without requiring complex database configurations, needing only access to archived redo log files for efficient log parsing and streaming.

Broad compatibility with Oracle databases

OpenLogReplicator supports a wide range of Oracle database versions and editions, making it a versatile solution for businesses of all sizes.

• Supported Oracle versions: Oracle 11.2g, 12.1g, 12.2g, 18c, 19c, 21c, 23ai
• Supported Oracle editions: XE/DE (Express & Developer Edition), SE, SE2, PE, EE (Enterprise Edition)

Additionally, it supports both active and standby Data Guard databases, giving enterprises greater flexibility in managing their replication strategies.le backup strategy, Gluesync provides the speed and flexibility required for modern MySQL environments.

Why choose OpenLogReplicator?

Traditional Oracle Change Data Capture (CDC) methods often require costly licenses, complex configurations and reliance on tools like LogMiner or XStream. OpenLogReplicator changes the game. It offers a lightweight, license-free solution that provides direct access to Oracle redo and archive logs without the need for additional Oracle components.

Unlike LogMiner-based approaches, which can introduce performance overhead, OpenLogReplicator operates independently: it ensures minimal impact on database performance. It reads redo and archive logs directly, enabling real-time, high-speed data replication with low latency and high reliability.

Another key advantage is simplicity. OpenLogReplicator comes fully integrated within Gluesync, meaning no manual setup or external tools are required. It runs autonomously within the Gluesync container, ensuring secure and isolated processing without exposing sensitive log data.

Additionally, broad compatibility makes it an ideal choice for businesses using any Oracle edition, from Express to Enterprise, including Data Guard standby databases. Whether you’re running on-premises or in the cloud, OpenLogReplicator provides a seamless, cost-effective CDC solution without the usual Oracle licensing constraints.

With no extra costs, no database load and full automation, OpenLogReplicator is the perfect tool for fast, secure and efficient Oracle data replication.
