If the trail file is missing the record trailer (truncated), you may need to skip the corrupted record or reposition the process to the next valid position. Skip to the next RBA ALTER , RBA Use code with caution. Copied to clipboard Reposition by Timestamp
: This mismatch signals to GoldenGate that the trail file was either cut off mid-write, incorrectly transferred across the network, or corrupted on disk. Common Triggers
If the source database, server hosting GoldenGate, or network drops frames mid-write, a trail file might be left incomplete. The next time the process initiates, it encounters a truncated tail. ogg-01184 expected 4 bytes but got 0 bytes in trail
On the system, locate the Pump process position corresponding to that trail file sequence.
If Logdump returns an EOF or an error indicating missing data, the file is physically truncated at this location. Step 2: Implement the Immediate Workaround
To help me tailor the next step, what are you running, and did this happen after a network drop or disk space issue? Share public link Expected 3,number,0 bytes, but got 4,number,0 bytes, in
The console spat the error for the third time:
If you are currently trying to fix this error on your system, let me know:
In rare instances involving migrations across differing CPU architectures (e.g., switching from Big-Endian AIX to Little-Endian Linux systems), GoldenGate processes might misinterpret block lengths. Common Triggers If the source database, server hosting
: Set up automated alerting on filesystem directories containing your GoldenGate dirdat/ paths to avoid partial write scenarios caused by space exhaustion.
Alter the source Pump process to regenerate that specific sequence: GGSCI > ALTER EXTRACT pump_prod, EXTSEQNO 1234, EXTRBA 0 Use code with caution.
When the Replicat reads the trail file and encounters instead of the expected length header, it means the file abruptly terminates or contains null corruption at that exact byte offset. Primary Root Causes 1. Network Interruptions during Transfer
Depending on your findings in Step 1, select the appropriate remediation path below. Option A: Roll Over to the Next Trail File (Most Common)
If the file ends abruptly without a proper trailer record, the file is confirmed to be truncated or corrupted. Step 3: Resolve via Repositioning (Data Pump or Replicat) Scenario A: The Error Occurs in the Data Pump
