Impact GUI/Core

    Stop a server by using the relevant command:
        On UNIX use $NCHOME/bin/stopGUIServer.sh or $NCHOME/bin/stopImpactServer.sh.
    Edit the file $IMPACT_HOME\wlp\usr\servers\<instance>\jvm.options.

    <instance>
        For GUI Server it is ImpactUI.
        For Impact Server it is the name of the Server Instance you provided during install time, the default is NCI.

    For your environment, specify the appropriate -Xms or -Xmx.
    Start the server by using the relevant command:
        On UNIX use $NCHOME/bin/startGUIServer.sh or $NCHOME/bin/startImpactServer.sh.
