param
is one of the following parameters:
[ BACKUPCPU ] cpu
specifies the processor number of the processor to be used as the backup processor. The
BACKUPCPU keyword can be omitted only if this is the first parameter specified in the
command. If this parameter is supplied, it must specify an existing processor that is different
from the primary processor. If this parameter is not supplied, the port mapper does not run
as a process pair.
TCPIP pname
specifies the name of a conventional NonStop TCP/IP process or NonStop TCP/IPv6
TCP6SAM process or Parallel Library TCP/IP TCPSAM process that provides an interface
to an Ethernet LAN. If this parameter is not specified but a DEFINE exists for
=TCPIP^PROCESS^NAME, that DEFINE is used. If neither this parameter nor the DEFINE
is specified, $ZTC0 is used.
COLLECTOR pname
specifies the name of the EMS collector to be used for EMS events. If this parameter is not
specified, the primary collector $0 is used.
Binding the Port Mapper to a Single Subnet
On systems running H06.24 and later H-series RVUs or J06.13 and later J-series RVUs, you can
bind the port mapper to an IP address by setting the TACL PORTMAP^BIND^IP parameter before
you start the port mapper. The IP address must be an IPv4 address in dotted-decimal format.
For example, to bind the port mapper only to IP address 192.168.10.10, enter this TACL command
before you start the port mapper:
PARAM PORTMAP^BIND^IP 192.168.10.10
In this example, after the port mapper is started, the port mapper binds only to 192.168.10.10
and listens to the requests only on this IP address, even if the provider has multiple IP addresses
configured. The benefit of this is improved performance, due to the port mapper’s load being
reduced by listening to the requests on only one IP address.
NOTE: If the TACL PORTMAP^BIND^IP parameter is not set to an IP address prior to starting the
port mapper, after starting the port mapper, it listens to the requests on all of the IP addresses that
are configured for the provider.
If the IP address specified in the TACL PORTMAP^BIND^IP parameter is not a valid IP address,
the corresponding bind_nw call fails and generates an RPC event specifying the error.
Examples
• In this example, an implicit RUN command invokes the port mapper process as a process pair
with processor 1 as the primary processor and processor 0 as the backup.
PORTMAP / NAME $ZPM1, PRI 148, NOWAIT,&
CPU 1, TERM $NULL.MSG / BACKUPCPU 0, TCPIP $ZTC1
• This explicit RUN command invokes the port mapper program $SYSTEM.SYSTEM.PORTMAP:
RUN $SYSTEM.SYSTEM.PORTMAP / NAME $ZPM1, PRI 148, NOWAIT,&
CPU 1, TERM $NULL.MSG / BACKUPCPU 0, TCPIP $ZTC1
Considerations
• Error messages received on startup are displayed in the OUT file, if possible. If an error occurs
while the process is writing to the OUT file, the home terminal is used.
• TACL ASSIGN commands are ignored.
