Types of ILM Runtime LicensesILM runtime licenses come in two forms: file-based and memory-based. The followingsections document those two forms of license.◆ File-Based RTNODE, RTSTOKEN or TOKEN Keys on page 156◆ Memory-Based RUNTIME Keys on page 156File-Based RTNODE, RTSTOKEN or TOKEN KeysThese are a file-based access key that is tied to a particular computer or server. Refer to theILOG License Manager online documentation for information about how to establish the filecontaining the key. You must communicate the location of this file to your application. Inorder to avoid potential conflicts with other runtime applications, it is a good idea to put thekey in a directory specific to your application by using one of the following:◆◆◆the C routine CPXputenv from the Callable Librarythe C routine CPXputenv from the Callable Library in the C++ API of ConcertTechnologythe method IloCplex.putEnv in the Java API of Concert Technology◆ the method Cplex.PutEnv in the .NET API of Concert TechnologyThese file-based keys are the most commonly used runtime licenses.Memory-Based RUNTIME KeysThese involve passing some information in the memory of your program to ILM. No filescontaining access keys are involved. Rather, you set the key in your program and pass it toILM by calling one of the following:◆◆◆◆the C routine CPXRegisterLicense from the Callable Librarythe C routine CPXRegisterLicense from the Callable Library in the C++ API ofConcert Technologythe method IloCplex.registerLicense in the Java API of Concert Technologythe method Cplex.RegisterLicense in the .NET API of Concert TechnologyRoutines and Methods Used for LicensingAll ILOG CPLEX applications either call the routine CPXopenCPLEX to establish theCPLEX environment, or use the appropriate constructor (IloCplex in the C++ and Java156 ILOG CPLEX 11.0 — USER’ S MANUAL
