Question
How are license restrictions implemented on specific host machines for IBM Rational® software products?
Answer
In order to implement restrictions on host machines for Rational® products, you can make use of the options file, ibmratl.opt. Use the HOST_GROUP syntax just the same way the GROUP syntax is used for specifying users.
The host machines specified in the options file would be able to fetch a license, while the other hosts would be denied.
This process is applicable for all Rational® products that use FLEXlm / FLEXnet license keys.
A typical host-based option file would look similar to the following:
HOST_GROUP <group_name> host1 host2 host3
INCLUDE <PRODUCT_NAME>:VERSION=<version details from license file> HOST_GROUP <group_name>
- After the options file has been edited, the association to this file needs to be mentioned in the license file (.dat file) by adding OPTIONS=<path_to_options_file> right next to the VENDOR ibmratl line, for example:
If a firewall is in use between server and clients, the SERVER and VENDOR lines would look like:SERVER license_server_name host_id VENDOR ibmratl OPTIONS=path_to_options_file
SERVER license_server_name host host_id <port number reserved for the lmgrd daemon> VENDOR ibmratl port=<port number reserved for ibmratl daemon> OPTIONS=path_to_options_file
- Save the license file, restart the license server, and reread the license file
The host machines specified in the options file would be able to fetch a license, while the other hosts would be denied.
For more information about the options file and the various commands see the IBM Knowledge Center:
Configuring the options file
Note: Check for errors in the lmgrd log file in case the specific host is not able to use the Rational® product. Use the IBM Cognitive Support Portal to search for solutions, or to create a support case.
