Is it possible to Sepereate out request log and out files for certain programs

Hi All

Basically, all concurrent request log and out files are stored in $APPLCSF/$APPLLOG and $APPLCSF/$APPLOUT directory resp.  But, we want only for certaion programs, log and out files needs to be generated in customized directoy location e.g. say /oracle/tmp_reqlog.

If it is possible ,how to achive it? And will this get purged automatically as usual by "Purge concurrent/request data"?

Thanks!!
