Xserver

[Ent. Storage]

HI,

We are trying to implement Oracle 9i AS with Oracle Reports 6i on a K370 box. Oracle 6i is X server dependant and we don't have a video card in the system, and we don't want to be dependant of a remote X session running 24/7 on a workstation.

There is a X11 Virtual Frame Buffer (Xvfb) workaround (doc id. KBRC00007660). This patch/procedure has been implemented, but we still get the following error when we start the reports server:

$ mwm: Another window manager is running on screen 0
mwm: Unable to manage any screens on display.

I verified all the procedure three times and made sure all the processes where running, without any success.

Help would be appreciated.

Thanks

Looks like you have a window manager mwm trying to start and erroring because presumably another Xserver - Xvfb maybe ? is usinging DISPLAY:0 (the default) and contending with sockets etc

What screen identifier did you tell xvfb to start on ? Try X :5 see attached for full details.

If that fails do you want a window manager and also xvfb running on the same system at the same time ?

ps -ef | grep X, mwm,dtwm,vuwm,xdm ?
