This message is most frequently seen in the following scenarios:
Then comes the command: STOP EXTRACT . Or perhaps a planned maintenance window. The gears grind. For a terrifying second, the DBA holds their breath—will it hang? Will it throw an ORA- error? Will it orphan a checkpoint and force a laborious rebuild?

Check the OGG process status via GGSCI. If the detachment was due to a stop command, the status should be STOPPED . This message is most frequently seen in the

When this message appears unexpectedly, follow these diagnostic steps to ensure replication continuity.
This message indicates that an Integrated Capture (Extract) process has disconnected from its deployment thread inside the Oracle Database. For a terrifying second, the DBA holds their
In environments with low transactional volume, an Integrated Extract might hit an idle timeout threshold. If no new redo data is generated for an extended period, or if network instability disrupts the IPC (Inter-Process Communication) between GoldenGate and the database instance, the client may detach to prevent resource locking. 4. Critical Database Errors (ORA- Errors)
Are there any specific showing up in your database alert log at that exact timestamp?
At first glance, this is a dry, technical epitaph for a process. It signals the end of a Change Data Capture (CDC) session. But for those who have stared into the abyss of data synchronization, this line is not an ending; it is a lullaby. It is the sound of a clean break, a controlled stop, and a rare triumph over the chaos of logistics. currently in the pipeline were processed or safely

To minimize unexpected client detachments and ensure smooth replication performance, implement the following operational best practices:
The most common reason for a successful detachment is intentional maintenance. If an administrator issues a STOP EXTRACT command in GGSCI or the Admin Client, the Extract process gracefully winds down. It notifies the database logmining server that it is leaving, resulting in a successful detachment log entry. 2. Database Shutdown or Restart
Do not alert on the message itself. Instead, alert on:
The database Streams Pool is too small to handle the volume of logical change records being mined.
