Ogg-01184 Expected 4 Bytes But Got 0 Bytes In Trail -

The error is a critical Oracle GoldenGate message indicating that a process (usually a Pump or Replicat) failed to read a mandatory 4-byte record trailer token from a trail file. This typically occurs when a record is incomplete or the file has been truncated prematurely. Understanding the Root Causes

Expected {3,number,0} bytes, but got {4,number,0} bytes, in trail {0}, seqno {1,number,0}, reading record trailer token at RBA {2, Oracle Help Center Extract & Pump Abends - Oracle Communities ogg-01184 expected 4 bytes but got 0 bytes in trail

The "expected 4 bytes but got 0" condition signifies that the GoldenGate process reached a Relative Byte Address (RBA) where it expected to find metadata, but instead encountered the end of the file. The error is a critical Oracle GoldenGate message

This is the most common cause. A trail file may be corrupted due to underlying disk issues, filesystem failures, or an abrupt system shutdown that prevented the Extract from properly closing the file.

If the corruption is at the very end of a trail file and the next trail file exists, you can skip the corrupted record:

Always use the STOP command in GGSCI rather than killing OS processes.
