Incisive Enterprise Manager Blank Screen

Hello,


I am running Incisive Enterprise Manager on a tiling window manager (dwm 6.0) and whenever I run vmanager, the second window that comes up (the actual incisive enterprise manager) is always a blank gray screen.


I had seen this before when using dwm to run certain programs, such as Matlab. In those cases, it had to do with the particular window-generating Java program assuming a reparenting window manager (not true for my wm, however). I tried using the wmname utility to tell the JDK that I do not have a reparenting wm, but that didn't work. I also tried setting and exporting _JAVA_AWT_WM_NONREPARENTING set to 1, but this also doesn't seem to work.


So my question is this: is there any other way I can get the program to load up correctly in my environment?

Thanks in advance!

    Ah, so the fix is using the older Motif-based X integration. It can be set by:

       export AWT_TOOLKIT=MToolkit

     

    After setting this and running vmanager again, the window appears correctly. Man, what a pain in the neck! Moreover, this temporary fix might break other applications, at least from what I have read, so if this is an issue that you have had, be wary of this "fix"!

    Hello Patrick.
    Well done figuring out the work-around! In all the years I've been supporting Enterprise Manager I'd never heard of this problem, perhaps because most users aren't so adventurous with their window manager! ;-)
    To avoid impacting other applications I guess you could start Enterprise Manager using a wrapper script that sets AWT_TOOLKIT for you, so that it doesn't need to be a global setting.

    On a related note, please be aware that Enterprise Manager is no longer being developed and has been replaced by the new Incisive vManager(R) tool, which is re-written from the ground up and uses new GUI toolkits. If you've not already seen it, you might want to take a look at some of the tutorial videos on the Cadence support site, or ping your local AE for a demo / evaluation.

    That is true, I think I would prefer to have these settings saved away for each separate GUI/toolkit/preferential issue so that one program's fix doesn't break something else down the road. Is there a resource out there describing where and what I ought to put in a wrapper script? I've had moments with a number of Cadence tools where I tediously configured something every time it launched (e.g. simvision) and kept thinking "I'd like to save ___ preferences as default and never have to think of it again", but I have never really explored that since up to that point I hadn't had re-parenting window issues. Is it just a simple *.sh or *.tcl file or is it something else?

    As to your second point, I aim to use the most functional, best supported tools. However, I'm not sure what the difference between Incisive vManager and the Incisive Enterprise Manager is. What I mean by that is when I run vmanager (that's what I type in the command line), the window title reads exactly: "Incisive Enterprise Manager". What I had assumed to be true until you pointed this out was that the two were just names describing the same piece of software (a common theme for Cadence tools); so now I'm a little unsure if the name I type into the command line is the "real name" and the title bar name was just neglected in the update process, or if there's something else going over my head here and despite typing out vmanager, I'm running something else.

    I suppose one way for me to wrap my head around this would be for me to go out and explicitly run Incisive Enterprise Manager, but I don't know what the command for that is.
