Find the last good checkpoint position of your target process.
A process is attempting to read from a position (RBA) that is actually beyond the physical end of the file. Recommended Resolution Steps 1. Automatic Trail Recovery (Recommended for OGG 12.1.2.1+)
To ensure your Oracle GoldenGate environment is resilient against file truncation errors, implement these preventive operational guidelines: ogg-01184 expected 4 bytes but got 0 bytes in trail
Reposition the source Extract or Pump back to that matching historical position.
Avoid forcefully killing GoldenGate OS processes (e.g., using kill -9 ). Always use SEND EXTRACT [group_name] STOP or STOP EXTRACT [group_name] in the ggsci prompt to ensure the final trail buffers are written to disk. Find the last good checkpoint position of your
Note the trail file name, sequence number (seqno), and Relative Byte Address (RBA) mentioned in the error (e.g., ./dirdat/xx000007 at RBA 246849346 ). : Open the Logdump Utility.
| Scenario | Recommended Action | | :--- | :--- | | | Perform a Forward Checkpoint Repositioning (see below). | | Count command failed | Perform a Clean Trail Rollover (see below). If the issue persists, escalate to Oracle Support. | Automatic Trail Recovery (Recommended for OGG 12
To understand exactly what is happening in your trail files without making blind changes, use the GoldenGate utility. It allows you to peer inside the binary trail files and examine transaction tokens. Open Logdump from the OGG home directory: cd /path/to/goldengate/ ./logdump Use code with caution. Open the trail file: OPEN /path/to/goldengate/dirdat/xx00000X Use code with caution.
If next returns an error or shows a partial record at the end of the file, the trail is indeed truncated. 3. Resolve the Issue Depending on the process type, use one of the following:
The OGG-01184 error is a critical, yet common, issue encountered in Oracle GoldenGate environments. It typically occurs in the Extract or Pump process and indicates a corruption or inconsistency within the trail file, frequently caused by abrupt process terminations, network interruptions, or storage issues.
