If the corruption is at the very end of a trail file and the next trail file exists, you can skip the corrupted record: ogg-01184 expected 4 bytes but got 0 bytes in trail

If the local trail on the source is corrupted, you must re-position the Extract process to a point in the database logs (SCN or timestamp) prior to the corruption and regenerate the trails. Prevention Best Practices

Host trail files on stable, high-performance filesystems to reduce the risk of I/O related corruption. OGG-01184 - Oracle GoldenGate Error Messages If you are using Oracle GoldenGate 12
