The 4 bytes referenced in the error message refer to the . In OGG trail files, each logical record is preceded by a 4-byte integer that indicates the total length of the following data payload. This design allows GoldenGate processes to read the file sequentially, knowing exactly how many bytes to read for the next record.
Always stop GoldenGate processes before rebooting or unmounting filesystems: ogg-01184 expected 4 bytes but got 0 bytes in trail
