Understanding OGG-01184: Trail File Mismatch The error OGG-01184 typically occurs when an Oracle GoldenGate (OGG) process (Extract or Replicat) attempts to read a record from a trail file, but the file ends prematurely or is corrupted. Specifically, the process expected a 4-byte length header for a data record but encountered 0 bytes (EOF). Common Root Causes

Automated Trail Recovery (Preferred for OGG 12.2+):If you are using Oracle GoldenGate 12.2 or higher, you can leverage Automated Remote Trail File Recovery: Stop the Pump process on the source. ogg-01184 expected 4 bytes but got 0 bytes in trail

: Network interruptions during transfer or hardware failures (disk errors, controller faults) can cause physical corruption where a block contains entirely zeros. Checkpoint Mismatch : Network interruptions during transfer or hardware failures

In newer versions, you can leverage built-in recovery features for remote trails: ogg-01184 expected 4 bytes but got 0 bytes in trail
