Configure the GoldenGate Manager process to automatically restart Extracts if they detach due to transient database or network blips.
. This confirms a clean shutdown of the handshaking between the OGG Extract process and the database's LogMiner server. Oracle Forums Review of Process Detachment Normal Lifecycle : This is a standard confirmation message during a manual STOP EXTRACT
If you encounter issues during or after the detachment, refer to the Oracle GoldenGate documentation and troubleshooting guides for assistance.
In the clamorous world of database administration, where the roar of transactions never ceases and the pressure for zero downtime is a constant hum, rare is the moment of genuine tranquility. We chase uptime percentages, wrestle with data drift, and monitor replication lag like a heartbeat. Yet, occasionally, the log file offers a message that transcends mere status update. It reads: OGG Capture Client successfully detached from Goldengate capture . Oracle Forums Review of Process Detachment Normal Lifecycle
SQL> SELECT CAPTURE_NAME, STATUS, CLIENT_STATUS, ERROR_NUMBER, ERROR_MESSAGE FROM DBA_CAPTURE WHERE CAPTURE_NAME LIKE 'OGG$CAP_%';
In Oracle GoldenGate (OGG), the message typically signifies a normal state transition or the graceful termination of an Integrated Capture (Integrated Extract) process . Understanding the Component
Example snippet from ggserr.log :
For a GoldenGate administrator, the true value of this message lies in the contextual information that surrounds it. It is not an error, but it can be the first symptom of a disconnected or failing replication stream. By understanding the underlying process architecture, maintaining vigilant monitoring of the DETACHED state, and following a methodical troubleshooting plan when issues arise, you can ensure this message is just a footnote in a log file, rather than the start of an emergency.
When an administrator issues the command to gracefully stop an Extract process, the client must unregister its active session from the database mining server. GGSCI> stop extract EXTNAMES Use code with caution.
If you see "Detached" as a status in the database views (like DBA_CAPTURE ), it means the Capture process is currently stopped and needs to be restarted from the Oracle GoldenGate Command Interface (GGSCI). Troubleshooting Checklist Yet, occasionally, the log file offers a message
When the client is "attached," it is in a symbiotic, high-stakes embrace with the database. It holds a Logical Change Record (LCR) cache. It maintains a checkpoint. It lives in a state of high alert, knowing that if it fails, the target system will fall out of sync, threatening disaster recovery, reporting accuracy, or active-active failover.
A: Yes, absolutely. Filter on severity: Info level. Alert only on ERROR or WARNING . But log retention of these "detach" events helps when auditing change windows.
