Capture | Ogg Capture Client Successfull !!top!!y Detached From Goldengate
If there is a transient network glitch between the server hosting the OGG Extract and the database server, the heartbeat between the Extract and the database logminer will fail. The database will then assume the client is dead and detach it. 5. GoldenGate Extract Abend
To resolve OGG Capture client detachment, follow these steps:
is adequately configured. Memory starvation in the streams pool can cause forced detachments. Check Database Alert Logs:
It indicates that a (e.g., a downstream mining, logdump, or custom application) has cleanly disconnected from the GoldenGate Capture process (e.g., Extract in classic or integrated capture mode, or the Local Capture in Microservices). If there is a transient network glitch between
Here’s a technical guide to understanding and handling the message.
Use INFO EXTRACT , SHOWCH to see if the Extract is stuck on a specific SCN (System Change Number). If it cannot find a required archived log, it may detach and wait. 4. Check Network Stability
The status should read STOPPED .

Is this happening on a or in a downstream deployment configuration? Share public link
I was working with OGG 21c (microservices deployment). One of my capture clients was hung while trying to process a large transaction. Instead of restarting the entire capture pipeline, I decided to detach the client, clear its state, and reattach. GoldenGate Extract Abend To resolve OGG Capture client
Essentially, the database is acknowledging that the GoldenGate process has stopped requesting data and the session has been closed cleanly. Common Scenarios Where This Occurs
(Note: 2GB is a baseline; high-throughput environments may require significantly more memory). Step 4: Check Extract Status and Restart
A "successful detachment" should not be misinterpreted. While the detachment might be successful and clean, the cause behind it could be an error that requires intervention. If you see this message and later find your Extract process in an ABENDED (abnormal end) or STOPPED state, the underlying issue is likely more serious. Here’s a technical guide to understanding and handling
Sometimes, a DDL (Data Definition Language) operation is captured, but due to a configuration setting or filter, the Extract needs to ignore it. To do this cleanly, it detaches from the capture session to reset the state.
Log into the GoldenGate Software Command Interface (GGSCI or Admin Client) and check the status of the Extract process. GGSCI> info extract EXTNAMES Use code with caution.
