ILOG CPLEX 10.1 User's Manual > Programming Considerations > Licensing an Application > Types of ILM Runtime Licenses

ILM runtime licenses come in two forms: file-based and memory-based.

File-Based RTNODE, RTSTOKEN or TOKEN Keys

These are a file-based access key that is tied to a particular computer or server. Refer to the ILOG License Manager online documentation for information about how to establish the file containing the key. You must communicate the location of this file to your application. In order to avoid potential conflicts with other runtime applications, it is a good idea to put the key in a directory specific to your application by using one of the following:

These file-based keys are the most commonly used runtime licenses.

Memory-Based RUNTIME Keys

These involve passing some information in the memory of your program to ILM. No files containing access keys are involved. Rather, you set the key in your program and pass it to ILM by calling one of the following:
