If the filesystem hosting the GoldenGate dirdat directory on the target server runs out of space, the writing process cannot commit the complete block. This leaves a partial record at the end of the trail file. 3. Abrupt Process or Server Shutdowns
Recreate Pump and Replicat, start fresh.
Whitelist the dirdat directory in all anti-virus, malware scanners, and OS backup scripts to avoid file-locking conflicts.
When this happens, your target database stops synchronizing. Data latency begins to grow. And if not handled correctly, you risk data divergence between source and target. ogg-01184 expected 4 bytes but got 0 bytes in trail
By understanding the mechanics of GoldenGate trail files and following structured recovery steps, resolving the OGG-01184 error becomes a manageable task rather than a roadblock.
An administrator manually deleted, truncated, or edited the trail files at the OS level while GoldenGate was still running.
If the corrupt RBA is at the (not in the middle of a multi-record operation), you can tell Replicat to skip that transaction. If the filesystem hosting the GoldenGate dirdat directory
If you need help resolving this issue, please share more details about your environment:

The most direct cause of this error is a corrupted trail file. A trail file is a binary file created by an Extract process that stores a logical change record for database replication. If this file gets corrupted, GoldenGate processes may be unable to parse the data stream, leading to the error. Abrupt Process or Server Shutdowns Recreate Pump and
The fundamental cause is that the , often because the file was truncated or corrupted. Common scenarios include:
If the file system hosting the GoldenGate trail files runs out of space while the Extract process is writing, the Extract cannot complete the current record. This results in a truncated or zero-byte trailing record. 2. Network Interruptions
Modern versions of GoldenGate can automatically rebuild remote trail files if they are corrupted. the Pump process on the source system.
: If the target filesystem runs out of space while a Data Pump is writing, the trail file may be truncated mid-record.
