LPSCHED(8) Maintenance Commands and Procedures LPSCHED(8)
lpsched - start the LP print service
lpsched [-f num_filters] [-n num_notifiers] [-p fd_limit]
[-r reserved_fds]
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.
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.
The following exit values are returned:
0
Successful completion.
non-zero
An error occurred.
/var/spool/lp/*
LP print queue.
lp(1), lpstat(1), svcs(1), attributes(7), smf(7), lpadmin(8),
lpmove(8), lpshut(8), svcadm(8)
The lpsched service is managed by the service management facility,
smf(7), under the service identifier:
svc:/application/print/server
Administrative actions on this service, such as enabling, disabling,
or requesting restart, can be performed using svcadm(8). The
service's status can be queried using the svcs(1) command.
