Using LOGDUMP

LOGDUMP is a great utility and a real bonus to the Oracle GoldenGate software bundle. Without LOGDUMP, we could not 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, go to the GoldenGate home directory and type "logdump", as shown in the following example.

[oracle@dbserver1 ggs]$ ./logdump
