If you start the installation process from the command line, you can specify the -log option to generate a verbose installation log. This log contains messages about events that occur during the installation, including informational, warning, error, and fatal messages. This can be especially useful for silent installations.
Unless the log contains a ‘fatal’ error, the installation completed successfully.
To create a verbose log file during installation, use the following command lines or scripts:
The -log parameter is optional. By default, the installation log is put in the log directory where you install the Administration Server. If for some reason, the installer fails, use this switch to generate a more detailed log: -log_priority=debug.
The path must be the full path to a file name. If the file does not exist, all folders in the path must exist before you execute the command or the installation program does not create the log file.
