Add a validation and recovery feature that detects OGG error cases like "expected 4 bytes but got 0 bytes in trail" and handles them gracefully: validate packet-trail lengths on read, log structured diagnostics, optionally attempt soft-repair, and surface a clear, actionable error to callers.

When a process abends with this error, use the following structured workflow to identify the damage and restore replication. Step 1: Locate the Faulty RBA

She looked at the error again: expected 4 bytes but got 0 bytes in trail . ogg-01184 expected 4 bytes but got 0 bytes in trail

Confirm the target filesystem is not full, which can lead to truncated trail files.

If a simple ETROLLOVER doesn't work, you may need to skip the specific RBA where the corruption occurred. This requires using the logdump utility, a powerful GoldenGate tool for viewing and analyzing trail files.

With this article, you now have both the surgical tools and the strategic vision to conquer OGG-01184. Good luck, and may your trails always be intact. Expected 3,number,0 bytes, but got 4,number,0 bytes, in

If you need to skip just the broken bytes within the same file (rare for 0-byte errors), position it to the next valid RBA discovered via logdump : GGSCI> alter replicat rep_name, extrba Use code with caution. Restart the Replicat: GGSCI> start rep_name Use code with caution. Best Practices to Prevent OGG-01184

This means GoldenGate expected to read 4 bytes of data (like a length field) but received nothing (0 bytes), halting the process. The error points to a specific trail file ( seqno ) and a specific Relative Byte Address ( RBA ) where the corruption occurred.

Force GoldenGate to generate a completely new, clean file sequence using the ETROLLOVER command: GGSCI > ALTER EXTRACT , ETROLLOVER Use code with caution. Confirm the target filesystem is not full, which

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

# Restart Extract from last checkpoint start extract <extract_name>

When GoldenGate reads a trail file, it processes data in structured blocks and records. A mismatch where the process expects a 4-byte header or length indicator but finds absolutely no data (0 bytes) means the file terminates abruptly or contains a structural anomaly. Root Causes of OGG-01184
