Informix Error -43023: Bad option usage: -n option requires a log number.

Cause and resolution

Bad option usage: -n option requires a log number.

The user entered the -n option and did not specify a log number. ON-Bar does not know which log to restore to in this command, so it cannot continue.

Specify the log number, after the -n option, and rerun the command.
