If you work remotely, you need to export the DISPLAY to the remote system, not to the local host.

What is your remote OS?

[DnD_1]

i mean, i ssh to the unix machine...like here

me(in stockholm) (ssh)----> hp ux(in copenhangen)....

any suggestion ? its quite very and i am new recruit :( ...

we have no oracle expert as well.....help please..

[Torsten.]

Better question: What is the OS on the system in front of you?

[DnD_1]

win XP :)

[Torsten.]

OK, you need a Xserver application for your PC (for example xming).

once this is running, use putty to connect to your hp-ux server:

> putty -X hpux-server

[DnD_1]

hi torsten.

i really have to do that ? is there any others way ?

so i will install the xserver application, and and re do the step as instructed in oracle installation guide....

thanks !!

[Torsten.]

That's the way it works ...

You need a Xserver on the local system (your PC).

[DnD_1]

i give it a try tomorrow.....but i think its hard to install a new software since the company is very strict in installing new software...

pardon my english :)

[Torsten.]

See

http://en.wikipedia.org/wiki/X_Window_System_protocols_and_architecture

the application that want to "draw" something is the client.

The application that "owns" the screen and does the drawing is the server.

So you need a local X-server if you want to see something on your pc.

[DnD_1]

another question torsten.

so i install the xming, then just run the command as normal ?

[DnD_1]

great, i will give it a try tomorrow.

sorry for my non sense question, never using oracle before..you been a great help !!!

thanks !!!!!!

[Dennis Handly]

I'm not sure if oracle has a non-GUI installer?
If so, you may try "unset DISPLAY".

[Hein van den Heuvel]

Dennis, Typically you really want to run the GUI for the OUI. There is a 'silent' mode for some version for some platforms.

DnD,

If you want to properly install Oracle 'stuff', then Yes you really have to run an X-server on your PC, or 'an' PC. Several options are avaibale for this. Reflection, RealVNC,...

I use CYGWIN.

That command "xhost +" (or preferably a more restrictive version of that) should be run at the PC, not the HPUX box.

This was discussed not too long ago in:
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1159922 [ ADMIN Note: Broken link removed]

Hope this helps,
Hein.

[DnD_1]

hi,

i installed the xming, and run the xhost +

and got this error

xlib:connection to "10.15.177.60:0.0"refused by server.
xlib:no protocol specified.

xhost:unable to open display "10.15.177.60:0.0"

my pc ip is "10.15.177.60"..

any idea ?

[Andrew Rutter]

hi,

did you export your display after installing the xming s/w.

if not telnet into the server and export the display to your pc ip address

#export DISPLAY=10.15.177.60:0.0

then try and run the application from server

Andy

[Hein van den Heuvel]

So did you actually start the X server?

For cygwin see my reply in the note I referenced earlier, or in:

[ ADMIN Note: Broken link removed]

And uh... before you even attempt OUI, always try xclock or xeyes, first on the PC itself, next on the targetted client.
Only bother to try OUI once those work.

Cheers,
Hein.

[Torsten.]

run putty from your PC, it will care about the DISPLAY var:

> putty -X hpux-server

[Stan Sieler]

Hi DnD,

To test X locally with xclock, do:

(on PC)

(start your X server)

(start a dos shell ("command" window))

cd \program files\xming
(or wherever your xserver code is)

dir x*.exe

see if you have an "xclock.exe" or
"xeyes.exe". Let's assume you
have "xclock.exe".

set DISPLAY=localhost:0.0
xclock

Bring your X window to the foreground, and you should see a small rectangle showing an
analog clock (the window for xclock).

Starting xclock may have resulted in a few
warnings that you can probably ignore.
Here's a sample session where I start xclock:

C:\Program Files>cd xming

C:\Program Files\Xming>xclock
Error: Can't open display:

C:\Program Files\Xming> set display=localhost:0.0

C:\Program Files\Xming>xclock
Warning: locale not supported by C library, locale unchanged
Warning: locale not supported by Xlib, locale set to C
Warning: X locale modifiers not supported, using default
Warning: Cannot convert string "-dt-interface user-medium-r-normal-s*-*-*-*-*-*-
*-*-*" to type FontSet
Warning: Unable to load any usable fontset
Warning: Unable to load any usable fontset

(xclock is now running and is visible
on the main X-window .. which I have configured as one big Windows window (some
X servers let you configure it so each new
X window is a new Windows window)

control-C in the DOS window to terminate
xclock, or click on the close gadget of its
window in X Windows.

Hope that helps you test your X setup!

[stan lin]

please su - root , and execute xhost +
oracle user have no permissiom by default.

FYI

[Torsten.]

@stan lin:
"xhost +" on a windows system?
Maybe with cygwinX only ...

@DnD:
Does it work now?

[Stan Sieler]

Torsten: yep, xhost + on a windows system.

Xhost.exe comes with xming, and (IIRC)Cygwin.
(But not with WRQ/Attachmate's Reflection X,
nor with Starnet's X-Win32).
(X-Win32 has an xhost-like list you can edit)
(Refelction X has an xhosts.txt file)

DnD: don't forget points :)

thanks,

Stan

[Torsten.]

I have no xhost with my xming, but I think I remember it was needed with cygwin ...

I just discovered that xming can do XDMCP.

[Avinash20]

Yes,, Best option is to install an Emulation software and start with the installation

YOu could install X-manager software on your Windows host and start dtlogin and xfs daemons on HP-UX server
# /sbin/init.d/dtlogin.rc start
# /sbin/init.d/xfs start

Once you login via emulation software, the display variable is automatically set to Windows hosts.

[Stan Sieler]

Torsten: no xhost with xming

Good point...it's not in the default package.
It is in the Xming-tools-and-clients package,
available at http://sourceforge.net/project/showfiles.php?group_id=156984, among others.

BTW, the xming xhost works fine with WRQ Reflection X. (I suspect it should work
with any PC X server.)
