lpsched(1M) System Administration Commands lpsched(1M)NAMElpsched - start the LP print service
SYNOPSISlpsched [-f num_filters] [-n num_notifiers] [-p fd_limit]
[-r reserved_fds]
DESCRIPTION
The lpsched command starts or restarts the LP print service.
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 service 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 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.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
