  • Change of server for CPLEX Optimization Studio Subscription

    By: Rory Keeley Rory Keeley , 10 months ago

    As announced to subscribers in early May, and to align with changes in IBM Cloud, we have changed the address of the server that provides license validation.

    If you have a CPLEX Optimization Studio subscription, this requires a simple action on your part to update the server address.

    Please set the variable CPLEX_STUDIO_KEY_SERVER to https://scx-cos.docloud.ibm.com/cos/query/v1/apikeys

    For example, on Windows in a command prompt:
    setx CPLEX_STUDIO_KEY_SERVER “https://scx-cos.docloud.ibm.com/cos/query/v1/apikeys”

    Or on Mac/Linux, in a terminal window:
    echo 'export CPLEX_STUDIO_KEY_SERVER="https://scx-cos.docloud.ibm.com/cos/query/v1/apikeys"' >> ~/.zshrc

    The old server address has been discontinued.
