Ogg Capture Client Successfully Detached From Goldengate Capture !full!

Ensure the checkpoint was updated prior to detachment. This guarantees that when the Extract restarts, it knows exactly where to resume reading.

Review the Oracle Database alert log around the exact timestamp of the detachment. Look for LogMiner or Streams errors, such as: ORA-04031 : Unable to allocate memory from the Streams pool. ORA-01291 : Missing logfile. Step 3: Verify Streams Pool Allocation

If the Extract encounters an error (such as running out of disk space for trails or hitting an unhandled database object), it will attempt to shut down. Even during an "abend," the Extract usually tries to detach gracefully from the database logmining server so that it can resume cleanly later. D. Database Instance Shutdown

If you are still experiencing this issue, please check the database alert log for the specific ORA-error code and ensure your GoldenGate version is patched to the latest recommended release.

A background database process (LogMiner) that mines the redo stream, filters transactions, and stages LCRs (Logical Change Records) into a memory SGA queue.

If the GoldenGate process is running on a different server than the database (Downstream Capture), ensure the SQL*Net connection is stable. Network timeouts can cause the capture client to drop the connection.

GoldenGate ensures all data currently in the memory queues are written to the trail files. Detachment 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. Look for LogMiner or Streams errors, such as:

When this command is issued, the Extract process finishes processing its current transaction memory, checkpoints its progress, and tells the database logmining server that it is disconnecting. The database then logs the successful detachment. B. GoldenGate Process Restarts or Upgrades

Rule of thumb: Allocate at least 1 GB of Streams Pool per GoldenGate Integrated Extract process, adjusting upward for heavy transaction volumes. Adjust GoldenGate Timeout Parameters

If the Extract process encounters a data error (e.g., fetching from an un-logged table, encountering an unsupported data type, or hitting a bug) it will "abend" (abnormally end). This sudden death forces the database to log the detachment message. Step-by-Step Troubleshooting Workflow

) running at the OS level. It registers itself with the database as a "client" to receive the logical change records (LCRs) mined by the database server. The Attachment: Even during an "abend," the Extract usually tries
