The 4 bytes referenced in the error message refer to the . In OGG trail files, each logical record is preceded by a 4-byte integer that indicates the total length of the following data payload. This design allows GoldenGate processes to read the file sequentially, knowing exactly how many bytes to read for the next record. GGSCI> INFO EXTRACT *, TASKS GGSCI> LAG EXTRACT

Use logdump to skip the bad header:

EOF encountered No more records Note the last valid record position. Then attempt to go beyond it:

echo "open /ggs/dirdat/aa000001" > check.cmd echo "n" >> check.cmd echo "EOF" >> check.cmd ./logdump < check.cmd > output.txt grep "Expected 4 bytes" output.txt Always stop GoldenGate processes gracefully before system shutdown:
