You must verify that
the ports that SAS and LSF use for communication are accessible from
other machines. The ports might not be accessible if a firewall is
running on one or more machines. If firewalls are running, you must
open ports so that communication works between the LSF daemons and
the instances of SAS. Issue the
telnet
<
host><
port>
command to determine whether a port is open on a specific host.
The default ports used
in a grid are:
-
LSF: 6878, 6881, 6882, 7869, 7870,
7871, 7872
-
Grid Monitoring Service: 1976
-
Platform Process Manager: 1966
If you need to change
any port numbers, modify these files:
-
LSF ports: LSF_ENVDIR/conf/lsf.conf
and EGO_CONFDIR/ego.conf
-
Grid Monitoring Service port: gms/conf/ga.conf
-
Platform Process Manager port:
pm/conf/js.conf
If you change the Grid
Monitoring Service port, you must also change the metadata for the
Grid Monitoring Server. If you change the Platform process Manager
port, you must also change the metadata for the Job Scheduler Server.
Ports might be used
by other programs. To check for ports that are in use, stop the LSF
daemons and issue the command
netstat -an |
<
search-tool><
port>,
where
search-tool is grep (UNIX)
or findstr (Windows). Check the output of the command for the LSF
ports. If a port is in use, reassign the port or stop the program
that is using the port.
SAS assigns random ports
for connections, but you can restrict the range of ports SAS uses
by using the
-tcpportfirst <first-port>
and
the
-tcpportlast <last-port>
options.
You can specify these options in the SAS configuration file or on
the SAS command line. For remote sessions, you must specify these
options either in the grid command script (sasgrid.cmd on Windows
or sasgrid on UNIX) or in the
Command field
in the logical grid server definition in metadata. For example, adding
the following parameters to the SAS command line in the grid script
restricts the ports that the remote session uses to between 5000 and
5005:
-tcpportfirst 5000 -tcpportlast 5005
