    Hi,

     

    I am using ILOG OPL IDE 6.3 which consist IBM ILOG CPLEX 12.1.0. My operating system is Server 2012. Both OPL & OS are in 64 bit. I am getting CPLEX Error 3019 ( Failure to solve MIP Problem). 

    However the same model with same input is running fine in 64bit Windows 7. What can be reason for this. 

    Thanks in advance for any suggestion.

    Hi

    3019 Failure to solve MIP subproblem.

    CPXmipopt failed to solve one of the subproblems in the branch & cut tree. This failure can be due to a limit (for example, an iteration limit) or due to numeric trouble. Check the log, or add a call to CPXgetsubstat in the Callable Library) for information about the cause.

    regards

    Thanks for your reply,

    I am wondering the same code with same setting is running good in OPL IDE for another version of Operating system (Windows7). I am attaching here my settings file for your reference .  

    I started using Windows server 2012 OS recently where I am getting this error.

    Also as suggested, If I want to add  CPXgetsubstat in OPL IDE to get more detail about the cause, How should I Insert. 

    Thanks in advance.
