Notes
After you configure FLOAT_CLIENTS_ADDR_RANGE, check the
lim.log.host_name file to make sure this parameter is correctly set. If this
parameter is not set or is wrong, this will be indicated in the log file.
Examples
FLOAT_CLIENTS_ADDR_RANGE=100
All client hosts with a domain address starting with 100 will be allowed access.
FLOAT_CLIENTS_ADDR_RANGE=100-110.34.1-10.4-56
All client hosts belonging to a domain with an address having the first number
between 100 and 110, then 34, then a number between 1 and 10, then, a number
between 4 and 56 will be allowed access.
Example: 100.34.9.45, 100.34.1.4, 102.34.3.20, etc.
FLOAT_CLIENTS_ADDR_RANGE=100.172.1.13 100.*.30-54 124.24-
*.1.*-34
All client hosts belonging to a domain with the address 100.172.1.13 will be allowed
access. All client hosts belonging to domains starting with 100, then any number,
then a range of 30 to 54 will be allowed access. All client hosts belonging to domains
starting with 124, then from 24 onward, then 1, then from 0 to 34 will be allowed
access.
FLOAT_CLIENTS_ADDR_RANGE=12.23.45.*
All client hosts belonging to domains starting with 12.23.45 are allowed.
FLOAT_CLIENTS_ADDR_RANGE=100.*43
The * character can only be used to indicate any value. In this example, an error will
be inserted in the LIM log and no hosts will be accepted to become LSF floating
clients.
FLOAT_CLIENTS_ADDR_RANGE=100.*43 100.172.1.13
Although one correct address range is specified, because *43 is not correct format,
the entire line is considered not valid. An error will be inserted in the LIM log and
no hosts will be accepted to become LSF floating clients.
Default
Undefined. No security is enabled. Any host in any domain is allowed access to LSF
floating client licenses.
HOST_INACTIVITY_LIMIT
Syntax
HOST_INACTIVITY_LIMIT=
integer
Description
Integer that is multiplied by EXINTERVAL, the time period you set for the
communication between the master and slave LIMs to ensure all parties are functioning.
A slave LIM can send its load information any time from EXINTERVAL to
(HOST_INACTIVITY_LIMIT-1)*EXINTERVAL seconds. A master LIM sends a
master announce to each host at least every
EXINTERVAL*HOST_INACTIVITY_LIMIT seconds.
The HOST_INACTIVITY_LIMIT must be greater than or equal to 2.
Increase or decrease the host inactivity limit to adjust for your tolerance for
communication between master and slaves. For example, if you have hosts that
frequently become inactive, decrease the host inactivity limit. Note that to get the right
interval, you may also have to adjust your EXINTERVAL.
