Working with Terracotta License Files
A Terracotta license file is required to run enterprise versions of Terracotta products. The name of the file is terracotta-license.key and must not be changed. Trial versions of Terracotta enterprise products expire after a trial period. Expiration warnings are issued both to logs and standard output to allow enough time to contact Terracotta for an extension.
Each node using an enterprise version of Terracotta software requires a copy of the license file or configuration that specifies the file's location. By default, the file is provided in the root directory of the Terracotta software kit. To avoid having to explicitly specify the file's location, you can leave it in the kit's root directory.
Or, more generally (if you are using BigMemory Max), ensure that the resource /terracotta-license.key is on the same classpath as the standard Terracotta runtime JARs. For example, the license file could be placed in WEB-INF/classes when using a web application.
Explicitly Specifying the Location of the License File
If the file is in the Terracotta installation directory, you can specify it with:
-Dtc.install-root=/path/to/terracotta-install-dir
If the file is in a different location, you can specify it with:
-Dcom.tc.productkey.path=/path/to/terracotta-license.key
Alternatively, the path to the license file can be specified by adding the following to the beginning of the Terracotta configuration file (tc-config.xml by default):
To refer to a license file that is in a WAR or JAR file, substitute productkey.resource.path for productkey.path.
Verifying Products and Features
There are a number of ways to verify what products and features are allowed and what limitations are imposed by your product key. The first is by looking at the readable file (terracotta-license.key) containing the product key.
Second, at startup Terracotta software logs a message detailing the product key. The message is printed to the log and to standard output. The message should appear similar to the following:
