The OGG-01184 Expected 4 bytes, but got 0 bytes, in trail error is a fatal PROCESS ABENDING error, meaning the GoldenGate process stops abruptly upon encountering it. The error itself indicates that the process was reading a trail file (a queue of database changes) but unexpectedly reached the end of a record while trying to read 4 more bytes of data. In Oracle GoldenGate's official documentation, the error’s cause is simply stated as "The actual length of the trail record is different from the length field". In practice, this means the trail file is corrupted, and its internal data record is incomplete.
