DISPLAY, TERM XTERM variables problem

[Burhan Koni]

Dear all
I have ORACLE APPLICATION 11i installed on HP-UX 11i. I have problem in diplaying reports in pdf or html format. one of the diagnostic commands:
# xterm -display Fin02.ora:0.0
Error: Can't open display: Fin02.ora:0.0
Error: Couldn't find per display information

# xdpyinfo
xdpyinfo: unable to open display "Fin02.ora:0.0".
#


also the value of TERM is dtterm from x-manager, and ansi from telnet session.


how to fix this ???

Thanks
Burhan

The TERM values are correct for dtterm and telnet sessions.

Can you try first exporting the DISPLAY and then opening xterm.

Error: Couldn't find per display information

This error usually occurs when the X11 is not able to point the local display itself.

Hi

- Is Fin02.ora your workstation or the server --> You have to set the display to your workstation
- Does the server know the name of your workstation --> try IP-Adress
- Is a X-Server running on your Workstation ?

Fin02.ora is the server

[Umapathy S]

Did you check as per Chris reply?
Is there a Xserver running in your workstation/windows.

Are you trying to connect to the server using an emulator or workstation.

Mostly this must be an workstation. Login to Fin02 and type xhost + (which allows the access)

But as I said before the local display itself is not proper.

xterm is an X-windows application. It needs to connect to an Xserver to perform. It uses the DISPLAY environment variable or -display argument to determine where that X-server runs. The part before the colon (Fin02.ora in your case) is the IP address of the Xserver process, the part behind the colon (0.0 in your case) determines the port number to be used.

An Xserver can be on HP-UX if you have a graphical console or on a PC running Linux with programs like XFree86 or Windows with Reflexion or something like that.

Now the error code you get means that xterm can not open a connection to the Xserver. So now there can be two problems: you have an authorisation problem or you don't have an Xserver at all on your server.

Before going further, check if you have a graphical console that should support X... or that you should point the display to your workstation.

Hi,

as Christian points out, where do you need the graphic output, on a pc or on a graphics console? Wherever this is, a Xserver must run there and the display options must be set for that machine. Check with xhost the hosts with access.

greetings,

The machine Fin02.ora must be running an Xwindow emulator. The concept of server and client is different for Xwindows. If you type a command such as xterm on a particular computer, then that computer is the client in Xwindows. The -display Fin02.ora:0.0 information is telling xterm to find an Xwindow display server on Fin02.ora which must be a graphics workstation or an Xterminal or a PC running an Xwindow emulator.

Is Fin02.ora a graphics computer with Xwindow capability?

[Steven E. Protter]

Add this line to .profile or /etc/profile

DISPLAY=$(who -m -u | awk '{print $8}'):0.0
export DISPLAY


This will insure that the DISPLAY variable won't be a problem and standard X Windows Emulator software will work.

Hi burhan,

i think you have to try to export the display....

try

> xhost +

> setenv DISPLAY Fin02.ora:0.0
