System Administration Commands                        lpsched(1M)



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).


     It is recommended that you start  and stop the LP print ser-
     vice using svcadm(1M).  See NOTES.

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
                         configuration, 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  neces-
                         sary 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
