Ogg-01184 Expected 4 Bytes But Got 0 Bytes In Trail Hot!

Depending on whether this error is occurring on an Extract or a Replicat process, you have two primary methods for recovery:

If the source trail is healthy but the target trail is truncated, try restarting the Pump with the ETROLLOVER command to skip the corrupted tail and start a new file: ALTER EXTRACT [pump_name], ETROLLOVER

Identify the sequence number before the corrupt file: ogg-01184 expected 4 bytes but got 0 bytes in trail

: Security scanners or third-party backup utilities locking down a trail file exactly while a GoldenGate process is attempting to append or process data can break standard I/O streams. 📋 Step-by-Step Troubleshooting Workflow

You lose exactly one transaction. You must manually reconcile that row(s) later. Depending on whether this error is occurring on

If the error occurs on the target side, it is usually because the Data Pump successfully read the source file, but the network or target storage truncated the file when writing it to the target system. Solution 1: Force the Data Pump to Re-send the File

If you are reading this, you have likely just encountered a nightmare scenario for any data replication engineer. Your Oracle GoldenGate (OGG) Replicat process has aborted with the cryptic message: If the error occurs on the target side,

: Set up automated alerting on filesystem directories containing your GoldenGate dirdat/ paths to avoid partial write scenarios caused by space exhaustion.

: Ensure PURGEOLDEXTRACTS with MINKEEP is configured on the source so trail files aren't deleted before they can be used for recovery.
