Client Successfully Detached From Goldengate Capture - Ogg Capture
In the complex ecosystem of log mining, where redo logs spin, SCNs advance, and data never sleeps, a clean detach ensures that no data is lost and that the next start will be flawless. For the vigilant DBA, the real work begins not when you see this message, but when you see it after an expected stop. An absent "successfully detached" log line is a far bigger warning than the message itself.
A: Almost never. A "successful" detach requires a final checkpoint. However, if you force-killed the extract, you wouldn’t see this message – you’d see an OGG error instead. In the complex ecosystem of log mining, where
This is healthy behavior for a controlled environment shutdown. Scenario 3: End of a Batch Processing Window In some architectures (e.g., batch-oriented replication), an extract might be configured to run for a specific duration or stop after processing a specific log sequence number (e.g., USING LOGFILE or END parameter). When the extract reaches its defined endpoint, it self-initiates a detach. A: Almost never
One message that frequently appears in these logs—often causing a momentary heart palpitation for new or even intermediate DBAs—is: Is this a symptom of failure? A hidden warning? Or just noise? This is healthy behavior for a controlled environment
The "detach" message is the final step in a controlled shutdown of this client-server relationship. Let's break down the exact log entry.
A: This indicates a mis-timestamped log or a zombie process. In normal cases, a detached client = stopped process. Use kill -3 on the process ID to verify.
INFO EXTRACT ext_sales, DETAIL Look for Current Checkpoint – it should be recent relative to the stop time. If an extract crashes and does not detach gracefully, you may see a database session lingering:
