Ogg Capture Client Successfull Besty Detached From Goldengate Capture Access
2025-03-15 10:00:05 ERROR ORA-03114: not connected to ORACLE. 2025-03-15 10:00:06 OGG capture client successfully detached from GoldenGate capture. Interpretation: The database connection was lost first; the detachment was a consequence, not a clean shutdown. Since the internal Capture process resides in the database, query its status:
However, context is everything. When accompanied by ORA errors, network disconnects, or unexpected abends, this message serves as the final log entry before a failure. By understanding the architecture—where the capture client (OGG) detaches from the internal capture process (database)—you can quickly distinguish routine maintenance from critical incidents.
Transient state. Monitor but usually harmless. Scenario 3: Idle Timeout Due to IDLETIMEOUT Parameter (Neutral) You have configured the IDLETIMEOUT parameter in your Extract parameter file (e.g., IDLETIMEOUT 30 meaning 30 minutes). If the Extract has no changes to process for that duration, it will automatically detach from the database capture process to free up resources. 2025-03-15 10:00:05 ERROR ORA-03114: not connected to ORACLE
In the world of Oracle GoldenGate for Big Data and classic integrated capture, this message signifies a specific and critical event in the lifecycle of a Extract process. Misinterpreting it can lead to unnecessary troubleshooting, while understanding it can help you architect more resilient replication pipelines.
When new redo logs arrive, it will reattach automatically. Since the internal Capture process resides in the
INSERT INTO heartbeat (ts) VALUES (SYSTIMESTAMP); COMMIT; Run this every 5 minutes via a scheduled job. This keeps the capture client active without idle timeout. Use the following query to see how long reattachment takes:
This article provides a deep dive into what this message means, the scenarios in which it appears (including graceful shutdowns, network timeouts, and parameter misconfigurations), and how to determine whether it represents normal operations or a hidden problem. To understand the detachment message, we first need to understand how Oracle GoldenGate captures data in modern deployments. Integrated Capture Mode Modern OGG (12c and later) uses Integrated Capture . Here, the Extract process does not directly read the redo logs. Instead, it acts as a client to a background server process inside the Oracle database known as the GoldenGate Capture process (also part of the logical replication framework inside the database engine). Transient state
Similarly, if the network between the OGG server and the database host drops, the client may interpret the broken pipe as a clean detach.
