Using LOGDUMP
LOGDUMP is a great utility and a real bonus to the Oracle GoldenGate software bundle. Without LOGDUMP, we will not be able to read a trail file, which would make us blind to troubleshooting data-related issues.
LOGDUMP has a command-line interface that allows you to open files, format the display, and navigate through a file, including filtering data. To invoke the utility, navigate to the GoldenGate Home directory and enter logdump, as shown in the following command:
[oracle@db12c ogg]$ ./logdump Oracle GoldenGate Log File Dump Utility for Oracle Version 12.1.2.1.0 OGGCORE_12.1.2.1.0_PLATFORMS_140727.2135.1 Copyright (C) 1995, 2014, Oracle and/or its affiliates.
