Hello,
I have included this stopping criterion in a model, just before the dvars.

execute PARAMS {
cplex.epgap = 0.01;
}

There is no .ops in the configuration. When a run it, I can follow the progression in the journal. I see that the relative gap is below 1%. From that point on, nothing is added to the journal but the configuration is still running and I don't have access to the solution.

Any idea what I'm doing wrong?

It's weird, when I run a configuration, it's not running on CPLEX! When I use the ILM, ilmlist, I see that the token for OPL is in use but not the token for CPLEX. Is there a solver in OPL? How can I get CPLEX to run my config?

Hi,

when solving an OPL model from the OPL IDE with a valid OPL license,  you don' t need a valid CPLEX license.
The CPLEX license is only mandatory (in addition to the OPL one) when you deploy the model (i.e. using APIs, or oplrun).

This explains what you see.
