On UNIX systems only, it is possible to request that a Manager or an adapter process roll over its log files. You do this by sending a SIGUSR1 signal to the process ID writing the log file. Use the stop command of your shell:
kill -USR1 <pid>
Upon receipt of the USR1 signal, a Manager or adapter process first writes an informational message to the end of the current log file, repeats the steps it executed at startup, and creates a new log file and a backup log file. All subsequent logging information is recorded to the new file.
To determine the process number <pid>, you can use the brcontrol utility or for an adapter, use the system™s ps command.
