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

If the underlying file system runs out of space while an Extract or Data Pump is writing, data terminates mid-record, yielding a literal 0-byte read where metadata should exist.

GoldenGate provides the logdump utility—your best friend for this error.

ggsci> ALTER REPLICAT rep01, EXTSEQNO 12, EXTRBA 4819000 ggsci> START REPLICAT rep01 ogg-01184 expected 4 bytes but got 0 bytes in trail

The core problem stems from a length mismatch: the GoldenGate internal headers indicate that a trail file should contain further transactional details, but the file system encounters an early end-of-file (EOF) marker.

Record the current SCN on the source database for all replicated tables: If the underlying file system runs out of

If logdump shows a bad header or unexpected EOF (End of File) at the very end, the file is truncated. Solutions to Resolve OGG-01184

In GGSCI , alter the failing process to start at the next sequence or RBA: ALTER [REPLICAT/PUMP] , EXTTRAIL , RBA Note: This may cause data loss for that specific record. Record the current SCN on the source database

If the error occurs at the very end of a trail file and Logdump shows nothing but empty bytes or EOF, you can safely instruct the Replicat to skip to the beginning of the next sequential trail file. Access the GoldenGate Software Command Interface: ./ggsci Use code with caution.

: This error signifies that the process expected a 4-byte record trailer token but found 0 bytes instead. This usually indicates that the trail file was truncated or not fully written—often due to a disk space issue, a network interruption during file transfer, or a source process (Extract) crashing while writing.
