Ogg-01184 Expected 4 Bytes But Got 0 Bytes In Trail !!exclusive!! Jun 2026

The most frequent cause. This can happen if an Extract process is interrupted while writing or if disk issues occur. Network Failures:

If the file is partially recoverable, use logdump to write a clean trail:

Start the process and monitor the view report output to confirm it successfully bypassed the broken boundary. Method B: Regenerate the Damaged Trail Segment ogg-01184 expected 4 bytes but got 0 bytes in trail

For Replicat, point it to the new trail file:

Identify the sequence number before the corrupt file: The most frequent cause

Sometimes, administrators manually copy or move trail files. If a file is copied in ASCII mode instead of binary (e.g., via FTP or SCP without binary flag), the byte count can be altered. Similarly, incomplete network transfers result in truncated files.

: Log into the OS and compare the physical size of the trail file with the RBA reported in the error. If the RBA is larger than the file size, the process is attempting to read non-existent data. Check for Concurrent Writes Method B: Regenerate the Damaged Trail Segment For

Restart the Pump process to overwrite/re-transmit the clean trail file to the target: GGSCI > START EXTRACT pump_prod Use code with caution.

Safely kill only the target server processes associated with that specific dead stream. (Caution: Do not terminate the Target Manager ( mgr ), Extract, or Replicat processes). Restart the Data Pump: START ER Use code with caution. Protocol 2: Altering to a Clean RBA (The Skip Method)
