Ogg-01184 Expected 4 Bytes But Got 0 Bytes In Trail !!top!! <90% VERIFIED>

The error ogg-01184 expected 4 bytes but got 0 bytes occurs when GoldenGate’s reader reaches a point in the trail file where it expects to read the header, but the file ends abruptly. The system reads 0 bytes instead of 4.

Is this error happening on an , a Pump , or a Replicat process? What version of Oracle GoldenGate are you running?

To avoid OGG-01184 in production:

If the error occurs on the source side's Data Pump process, the typical solution is to have the process roll over to a new trail file: ogg-01184 expected 4 bytes but got 0 bytes in trail

Troubleshooting Oracle GoldenGate Error OGG-01184: Expected 4 Bytes but Got 0 Bytes in Trail

If your trail files are written to a Network File System (NFS) or a mounted volume, a network glitch or storage subsystem timeout can interrupt the write operation, leaving an incomplete trail file.

If you get "Failed to read header" or "4 bytes expected", the file is truncated at that position. The error ogg-01184 expected 4 bytes but got

A typical error stack in the ggserr.log looks like:

If you cannot regenerate the data and the missing payload represents a negligible transaction that you are willing to manually reconcile later, you can force the Replicat to skip to the next sequence file.

When a process abends with this error, use the following structured workflow to identify the damage and restore replication. Step 1: Locate the Faulty RBA What version of Oracle GoldenGate are you running

When this happens, your target database stops synchronizing. Data latency begins to grow. And if not handled correctly, you risk data divergence between source and target.
