In Trail | Ogg-01184 Expected 4 Bytes But Got 0 Bytes

If the trail file is fundamentally readable except for the final incomplete transaction block, you can force the reading process to consider the current truncated point as its hard endpoint.

If the error occurs on a or Replicat , compare the physical byte size of the corrupted trail file sequence on both the source system and the target system.

Find the startup checkpoint timestamp of the damaged trail file. ogg-01184 expected 4 bytes but got 0 bytes in trail

Sometimes, the input checkpoint position for a Pump or Replicat is greater than the actual physical size of the trail file, leading the process to seek data that does not exist.

To resolve OGG-01184, you must move the reading process past the corrupted record or regenerate the affected trail file. 1. Perform a Trail Rollover (Primary Fix) If the trail file is fundamentally readable except

The OGG-01184 error usually signifies a benign issue—specifically, an empty trail file created by the OS or a process interruption. In most cases, identifying and removing the and restarting the process resolves the issue immediately. However, always verify file sizes and use Logdump to ensure you are not deleting valid data before proceeding with deletion.

Optimizes network packet sizes to handle intermittent network dropouts cleanly. Sometimes, the input checkpoint position for a Pump

Never use kill -9 on GoldenGate processes. Use STOP EXTRACT/PUMP within GGSCI.

ls -ltr /u01/gg/dirdat/rt*

The most common real-world culprit is a full disk or an enforced disk quota limit on the dirdat filesystem. If the source Extract is actively writing a transaction block and the storage volume hits 100% capacity, the write stream is severed mid-transit. The transaction record header is saved, but the trailing 4-byte verification token is never written to disk. 2. Network Interruptions and Hard Crashes

In newer versions, you can leverage built-in recovery features for remote trails:
