NAME

     lpsched - start the LP print service


SYNOPSIS

     lpsched  [-f num_filters]  [-n num_notifiers]  [-p fd_limit]
     [-r reserved_fds]


DESCRIPTION

     The  lpsched command  starts or restarts the  LP print  ser-
     vice.

     The  lpshut command stops the  LP print  service.   Printers
     that are restarted using lpsched reprint (in their entirety)
     print  requests  that   were   stopped   by    lpshut.   See
     lpshut(1M).


OPTIONS

     The following options are supported:

     -f num_filters
           Specifies the number of concurrent slow  filters  that
           may  be run on a print server. A default value of 1 is
           used if none is specified. Depending on server  confi-
           guration,  a  value of  1 may cause printers to remain
           idle while there are jobs queued to them.

     -n num_notifiers
           Specifies  the  number  of   concurrent   notification
           processes  that  can  run on a print server. A default
           value of  1 is used when none is specified.

     -p fd_limit
           Specifies the file descriptor resource limit  for  the
           lpsched  process.  A default value of  4096 is used if
           none is specified. On extremely large and active print
           servers, it may be necessary to increase this value.

     -r reserved_fds
           Specifies the number  of  file  descriptors  that  the
           scheduler  reserves  for internal communications under
           heavy load. A default value of  2 is used when none is
           specified.  It  should not be necessary to modify this
           value unless instructed to do so when  troubleshooting
           problems under high load.
