Ogg-01184 Expected 4 Bytes But Got 0 Bytes In Trail 【Latest ✪】

ggsci> ALTER REPLICAT rep01, EXTSEQNO 12, EXTRBA 4819000 ggsci> START REPLICAT rep01 You lose all changes after RBA 4819000. Resync required for the missing window. Solution 3: Recover from Source Trail or Archive (Recommended for Production) If you have archive trails enabled ( EXTTRAIL with ROLLOVER at source) or a backup of the trail files before corruption:

This error is not a simple configuration mismatch. It typically signals a serious structural problem in the trail file—the lifeblood of your GoldenGate replication. At its core, GoldenGate expected to read a 4-byte control field (usually a record length indicator or a checksum), but instead found an End-Of-File (EOF) marker or a null value (0 bytes). ogg-01184 expected 4 bytes but got 0 bytes in trail

This article provides a complete, step-by-step guide to diagnosing, fixing, and preventing the OGG-01184 error. We will cover everything from basic concepts to advanced surgical recovery techniques. What is a GoldenGate Trail File? Before fixing the error, you must understand what GoldenGate is trying to read. A trail file (e.g., dirdat/rt000001 ) is a binary sequence of records. Each record represents a database operation (INSERT, UPDATE, DELETE, DDL). The structure is: ggsci> ALTER REPLICAT rep01, EXTSEQNO 12, EXTRBA 4819000

TransInd: 1 (First record of transaction) XID: 3.27.12345 Add a FILTER or MAP exception in the Replicat parameter file: It typically signals a serious structural problem in
