Before applying a fix, inspect your environment using these steps to confirm the scope of the problem. 1. View the Detailed Process Error Log

the Data Pump on the Source. The GoldenGate manager will re-negotiate a clean, un-competed stream connection. Solution B: Force a Trail Roll-Forward (ETROLLOVER)

We cannot simply restart the process. The EXT_PROD extract is smart; it checks data integrity. If we restart it, it will re-read the trail, hit the same spot, and crash again with the same error. The trail file is physically corrupt or logically incomplete.

If Logdump fails to read beyond that position or throws an unexpected EOF warning, the file is officially truncated at that RBA. 🚀 Solutions and Resolution Strategies ogg-01184 expected 4 bytes but got 0 bytes in trail

: Use the TCPBUFSIZE and TCPFLUSHBYTES parameters within your Pump options to optimize network packets, and ensure TCP keepalive parameters are tuned globally to avoid half-closed socket failures during large data transfers.

If this error causes a Data Pump to abend on the source, check the target (Replicat side) machine for orphaned server connections: ps -ef | grep server | grep dirdat Use code with caution.

Is the error occurring on the or the target (Replicat) ? Have you checked the available disk space on both servers? What Oracle GoldenGate version are you running? Before applying a fix, inspect your environment using

View the information for your Extract to see the new trail sequence context: INFO EXTRACT extract_name Use code with caution.

: If the target filesystem runs out of space while a Data Pump is writing, the trail file may be truncated mid-record.

:

This behavior typically happens when a file writer process is abruptly interrupted, or when network communication or disk limits prematurely cut off the data stream. 🔍 Understanding the Mechanics of OGG-01184
