CHGLPDA (Change LPD Attributes) Command
Purpose
The Change LPD Attributes (CHGLPDA) command provides an interface to
configure line printer daemon (LPD) parameters. The changes made by this command
take effect the next time the LPD servers are started.
Restrictions: You must have *IOSYSCFG special authority to use this
command.
Optional Parameters
AUTOSTART Specifies whether to automatically start the LPD servers
when TCP/IP is started by the Start TCP/IP (STRTCP) command. When LPD is started
by the Start TCP/IP Server (STRTCPSVR) command, this parameter is ignored and
the number of initial servers defined is started regardless of the value of this
parameter.
*SAME: The autostart value that was previously set does not
change.
*YES: Start the number of servers defined in the NBRSVR parameter.
*NO: Do not start the number of servers defined in the NBRSVR
parameter when the STRTCP command is called.
NBRSVR Specifies the number of LPD servers to start initially when
LPD is started by either the STRTCP command or the STRTCPSVR command. The
initial number of servers is 2.
The STRTCP command starts all the servers specified in the CHGLPDA
command. The STRTCPSVR command starts only one LPD server, regardless of
the number of the servers currently running.
LPD works most efficiently when two or more servers are running. Running only
one server works, but no jobs can be received while a current job is running. If
a large print job is running, new jobs have to wait before LPD is ready to
accept any new LPR requests.
*SAME: The number of servers that was previously set does not
change.
*DFT: The number of servers is set to the default value of 2.
number-of-servers: The number of servers requested in this
parameter is started the next time the LPD server is started. Valid values range
from 1 through 20 servers.
Examples
Example 1: Displaying the Change
LPD Attributes Display
CHGLPDA
This command, when prompted, shows the Change LPD Attributes display.
Example 2: Starting the LPD Servers
Automatically
CHGLPDA AUTOSTART(*YES) NBRSVR(5)
This command indicates that the next time LPD is started by the STRTCP
command, 5 LPD servers are to be started.
Example 3: Changing the LPD
Attributes to not Start any LPD
Servers when the STRTCP Command Is
Issued
CHGLPDA AUTOSTART(*NO)
This command indicates that the next time the STRTCP command is issued, no
LPD servers are started automatically. If the STRTCPSVR command is issued and
STRTCPSVR indicates LPD servers to be started, CHGLPDA AUTOSTART(*NO) has no
effect.
