Ogg-01184 Expected 4 Bytes But Got 0 Bytes In Trail Fixed ✧

Take note of the sequence number ( 7 ) and the Relative Byte Address ( 246849346 ). Step 2: Analyze the Trail with Logdump

Using mismatched GoldenGate versions between the source and target systems without explicitly defining the trail file format version can cause reading errors. A newer Extract might write headers that an older Replicat or Pump cannot interpret, mistaking the byte alignment. 5. File System Corruption or Third-Party Interference ogg-01184 expected 4 bytes but got 0 bytes in trail

This is the most common cause. A trail file may be corrupted due to underlying disk issues, filesystem failures, or an abrupt system shutdown that prevented the Extract from properly closing the file. Take note of the sequence number ( 7

This creates a new trail file (e.g., increments sequence from Reposition the Pump to the start of this new sequence: ALTER PUMP , EXTSEQNO , EXTRBA Use code with caution. Copied to clipboard Common Causes to Investigate Network Failures This creates a new trail file (e

To confirm whether the file is truly truncated at that exact RBA, use the built-in GoldenGate Logdump Reference utility : Open Logdump from your terminal: logdump Use code with caution. Open the problematic trail file: Logdump 1 > open ./dirdat/no000007 Use code with caution. Enable header formatting display: Logdump 2 > GOTO 246849346 Use code with caution.

The error OGG-01184 is a common stumbling block in Oracle GoldenGate (OGG) environments. It generally occurs in the 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.
