Use the Error Log

Use the Oracle GoldenGate error log to view:

• a history of commands

• Oracle GoldenGate processes that started and stopped

• processing that was performed

• errors that occurred

• informational and warning messages

Because the error log shows events as they occurred in sequence, it is a good tool for detecting the cause (or causes) of an error. For example, you might discover that:

• someone stopped a process

• a process failed to make a TCP/IP or database connection

• a process could not open a file

To view the error log, use any of the following:

• Standard shell command to view the ggserr.log file within the root Oracle GoldenGate directory

• VIEW GGSEVT command.

You can control the ggserr.log file behavior to:

• Roll over the file when it reaches a maximum size, which is the default to avoid disk space issues.

• All messages are appended to the file by all processes without regard to disk space.

• Disable the file.

• Route messages to another destination, such as the system log.

This behavior is controlled and described in the ogg-ggserr.xml file in one of the following locations:
