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.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
