You can use the GoldenGate Logdump utility to view records in the GoldenGate trail files. The Logdump
utility is part of the regular GoldenGate software installation. Logdump lets you view the unstructured
trail data in hex and ASCII format and count the number of records in the trail for debugging purposes.
You can also filter the trail for desired records and save them to a new trail for reprocessing if needed.
how to use logdump：

After you open the trail file, you need to turn on some useful features to make full use of the
Logdump utility. The first command is GHDR ON. It enables display of the record header for the
transactions in the trail file for Oracle GoldenGate:
Logdump 51 >ghdr on
Next, you need to toggle the option for viewing the hex and ASCII values for trailfile data. To do so,
execute the detail data command:
Logdump 52 >detail data
Now you can move to the next record in the trail file by using the next command in Logdump. When
you issue the next command, Logdump moves forward one record:
Logdump 53 >next
