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 speci‐
fied.
-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 nec‐
essary to increase this value.
-r reserved_fds Specifies the number of file descriptors that
the scheduler reserves for internal communica‐
tions 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 prob‐
lems under high load.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
