Edit the DEFINES Setting
The DEFINES setting in the flexnetls.conf unit file is the same as EXTRA_SYSPROPERITES in the flexnetls.settings file used in the legacy (SysV init) license-server service installations. By design, this setting has no corresponding command-line option to update its value; therefore, you need to edit the setting manually in the configuration file. For instructions on manually editing this file, see Edit the .conf File Manually.
This setting is used to define one or more system properties (each in -Dkey=value format) that the license server needs to pass to the Java Runtime system to support certain network functionality, such as an HTTP proxy.
For example, if you plan to have the license server communicate with the back office through an HTTP proxy, use this setting to identify the proxy parameters needed to configure the server. (For details, see Proxy Support for Communication with the Back Office in the More About License Server Functionality
DEFINES="-Dhttp.proxyHost=10.90.3.133 -Dhttp.proxyPort=3128 -Dhttp.proxyUser=user1a
-Dhttp.proxyPassword=user1apwd35"
By default, this setting has no properties defined.
