This error effectively means GoldenGate attempted to read a specific header or record block from the trail file but encountered an End-of-File (EOF) marker immediately (receiving 0 bytes) instead of the expected data structure (expected 4 bytes). There are three primary scenarios that lead to this error: 1. Zero-Byte Trail Files (Empty Files) This is the most frequent cause. GoldenGate rolls over to new trail files based on size limits (e.g., MEGABYTES 500 ). Sometimes, due to I/O latency, network glitches (in heterogeneous environments), or improper shutdowns, a trail file is created in the file system with a size of 0 bytes . When the Replicat tries to open this file, it expects a valid file header but receives nothing, triggering the error. 2. Corrupt or Incomplete Trail Files If the Extract process was terminated abruptly (e.g., a server crash or a kill -9 command) while writing to the current trail file, the file may be "truncated." The file exists and has a size greater than 0, but the data stream cuts off in the middle of a record. When the Replicat reaches this cut-off point, it expects the next chunk of data but hits the EOF. 3. Extract Not Running (Stale Checkpoints) The Replicat may have processed all available data and is attempting to read the next trail file in the sequence. If the Extract process on the source has stopped or is lagging significantly, it might not have created the next trail file yet, or it has created a placeholder file that is currently empty. Diagnostic Steps Before attempting a fix, verify the state of your trail files using the following steps. Step 1: Check Process Status Check if the source Extract is running.

GGSCI> INFO EXTRACT <extract_name> If the Extract is stopped or Abended, resolve the Extract issue first. If the Extract is running, note the sequence number of the trail file it is currently writing to. Navigate to the directory where the trail files reside (both Source and Target) and check the file sizes. Lomp Graias New Tools. The Diana
Error Code: OGG-01184 Message: Expected 4 bytes but got 0 bytes in trail Category: Trail File Read Error / End-of-File Handling Overview The error OGG-01184 is a common stumbling block in Oracle GoldenGate (OGG) environments. It generally occurs in the Replicat process (though it can appear in downstream Extracts) when the process attempts to read a trail file that is empty, incomplete, or physically shorter than the metadata expects.
