While the message itself specifies a "successful" event, administrators should verify that the detachment matches intended operations and hasn't led to stuck processes or replication lag. Step 1: Check GoldenGate Process Status Step 1: Check GoldenGate Process Status Check network

Check network stability between the GoldenGate deployment and the database. Check if the Oracle Streams Pool size is undersized, causing the database to kill the logmining session. 5. Best Practices for Managing GoldenGate Captures

Scenario 3: The Extract is running, but this message randomly appears in the database alert log. Best Practices for Managing GoldenGate Captures Scenario 3:

Always prefer stopping extracts manually via GGSCI before performing database maintenance, rather than letting a database shutdown force the detachment. Conclusion

The most common scenario is an Administrator issuing a stop command: such as maintenance

This message indicates that the OGG capture client, which is responsible for capturing data changes from a source database, has been cleanly separated from the GoldenGate capture process. This detachment is a normal operation that can occur for various reasons, such as maintenance, troubleshooting, or configuration changes.

: Ensure ORACLE_HOME and your PATH are correctly set to match the database version. Version mismatches between the OGG build and the Oracle binary can cause abrupt disconnections.
