The "detach" message is the final step in a controlled shutdown of this client-server relationship. Let's break down the exact log entry.
In all these cases, you will see the line after the failure, acting as a confirmation that the client gave up and disconnected cleanly. Part 6: Best Practices for Managing Integrated Extracts To ensure that "detached" always remains a benign message and never a sign of a forced disconnect, follow these best practices: 1. Use Graceful Stop Commands Always use STOP EXTRACT <name> (without ! or ABORT ). Aborting an extract bypasses the graceful detach and can leave orphaned LogMining sessions on the database. The "detach" message is the final step in
-- In the database: SELECT * FROM V$LOGMNR_PROCESSES; If a mining server exists for an extract that is no longer running, remove it: Part 6: Best Practices for Managing Integrated Extracts
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. Aborting an extract bypasses the graceful detach and
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?
