apps.fnd_file.put_line only writ into log file when the concurrent is completed?

 hi :

I used apps.fnd_file.put_line to write information into log file of concurrent program.  so far so good.  However, the log information is ONLY write to log file until the concurrent program is completed.  We have a case that the custom concurrent program suppose to take an hour to run,  During that hour, no one really know the status of the program.   I hope the log file can offer the progress status of the concurrent program.

Is there a way the log message can be write to log file during the run time of concurrent program?
