Compare the RBA mentioned in the error with the actual size of the trail file on the disk. If the RBA is larger than the file size, the file is definitely truncated. 3. Resolution Strategies
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.
In remote trail scenarios, network interruptions during a transfer can result in a partial file being written to the target system. Step-by-Step Troubleshooting and Resolution 1. Identify the Corrupted Trail File and RBA ogg-01184 expected 4 bytes but got 0 bytes in trail
Ensure the dirdat directory has enough space to prevent partial writes.
Always use the STOP command in GGSCI rather than killing OS processes. Compare the RBA mentioned in the error with
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
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 Resolution Strategies This is the most common cause
Host trail files on stable, high-performance filesystems to reduce the risk of I/O related corruption. OGG-01184 - Oracle GoldenGate Error Messages
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
If the corruption is at the very end of a trail file and the next trail file exists, you can skip the corrupted record:
