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 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(8).
It is recommended that you start and stop the LP print service using
svcadm(8). 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.
