Arnold uses a floating-license mechanism based on RLM from Reprise Software Inc.
Download RLM Server tools
Licensed users need to install the RLM license manager package which can be downloaded from the following links, make sure to download the right platform for your license server:
- RLM License Server tools for Windows 64-bit
- RLM License Server tools for Linux 64-bit
- RLM Licence Server tools for Mac OSX 64-bit
Starting the license server
The license server must run on a machine that all the render nodes can connect to. On the server machine, and once you have received a license file from us, you can start the license server with the following command:
Note that on some Unix-like systems (Linux, OS X), you may have to type:
if the current directory is not in the system path.
A license file is an ASCII text file with the following structure:
In the above example, the license server is localhost and the port is 5053 (the default port for RLM). If you need to change the license port, you can simply update it in the license file.
On the client machines, Arnold will try to use the localhost as the license server. If your license server is in a different machine, you will need to set the
ARNOLD_LICENSE_HOST environment variable and point it to the license server name. It will also try the default RLM port (5053). If you have changed the port in the license file, you must also set the
ARNOLD_LICENSE_PORT environment variable so that it matches the port in the license file.
|localhost||License server name|
It's not possible to specify multiple servers in these variables only, see below.
Multiple license servers
Since Arnold 188.8.131.52, we also support multiple license servers with additional environment variables. We now also recognize the RLM-standard variables
Licenses will be searched for in the following order:
First, from the contents of
solidangle_LICENSE, which can contain a list of multiple servers/ports in the following format:
server<N> can be
host@port (the port is optional and defaults to 5053).
Second, from the contents of
RLM_LICENSE, with the same format as above.
Finally, from the contents of
ARNOLD_LICENSE_PORT, which together define a single license server target, see above.
