Hi,
I have a situation in which I run some (rather large ~1GB) mps file with MIP formulation from cplex interactive command line and I obtain a feasible solution quite fast (and a good solution after few more minutes). However, when I run the same mps file using Java API (by importing the mps file and solving) in a simple Java application, I am getting the following exception essentially immediately after cplex.solve() is invoked:
ilog.cplex.CpxException: CPLEX Error 1217: No solution exists.
at ilog.cplex.CplexI.CALL(CplexI.java:3754)
at ilog.cplex.CplexI.setStatus(CplexI.java:4877)
at ilog.cplex.CplexI.solve(CplexI.java:2327)
at ilog.cplex.IloCplex.solve(IloCplex.java:9306)
I have also tried to configure some parameters within the Java code that control the policy of using node files, their memory and all sort of branching policies that are proposed on the Cplex 12 document to solve out-of-memory problems (I have a feeling that the exception is initially caused by memory issues).
Can you please advise?
