Initialize the target from scratch using:

indicates that an Oracle GoldenGate process (typically a ) expected to read 4 bytes for a record trailer but found 0 bytes instead. This usually signifies trail file corruption

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

Sometimes, administrators manually copy or move trail files. If a file is copied in ASCII mode instead of binary (e.g., via FTP or SCP without binary flag), the byte count can be altered. Similarly, incomplete network transfers result in truncated files.

Check for disk space issues or network jitter, as these are common environmental causes for trail corruption.
