Executing projects in a separate process

Memory management

The CPLEX® Studio IDE and the execution of OPL projects are in different processes. This enables the IDE and the project execution to go up to the theoretical maximum heap size of the machine, depending on its memory resources.

Security aspects with respect to firewalls on Windows systems

Because the CPLEX Studio IDE and the model execution are in different processes, at the first launch of the IDE, the firewall can display a warning about security, which comes from the connection between the two processes. To get rid of this warning, you should choose to allow this connection forever. If you do not accept the connection, you will not be able to execute your configurations.

Configuration of the spawned solving process

The Java™ spawned process can be configured using Java options. To configure the spawned process, open the Run Configurations panel via the menu:

and select the Arguments tab, where you can add your options.
