Unable to run xclock from oracle

[Nilesh Naik]

I able to run xclock by ssh client software (Putty / CygWin) by root login but when switch to i created user oracle then i get error:Can't open display. What parameter i have to set in oracle user environment (Profile).

Hi,

export correct display paramters it should work

example:

export DISPLAY=:0.0

[skt_skt]

export DISPLAY=:${DISPLAY NUMBER}.0

If you ssh in as root, then su to oracle, you will need to authorize the display as well.

The script below does this. Assuming you save it as "disp_auth.sh", while still root, your would run "disp_auth.sh oracle" and then "su - oracle" followed by setting / exporting the DISPLAY variable as it was when you were root.


!/usr/bin/ksh

if [ "$1" != '' ]
then
echo
AUTH=/usr/bin/X11/xauth
outfile=${HOME}/`whoami`.disp

echo $AUTH -i add `$AUTH list | tail -1` > ${outfile}
echo export DISPLAY=$DISPLAY >> ${outfile}

chmod 755 $outfile
su - $1 -c "${outfile}"
else
echo 'Usage: disp_auth.sh '
fi

Follow-up

if using ssh and su'ing to oracle, echo $DISPLAY while still root. You will need to set/export this value when you are oracle. It will appear either as
::0 or
localhost::0

the offset is determined by ssh config

script is not work on server it says error line 1

also we tried export display but that also not work.

export DISPLAY=:0.0
i tried with above command

[OldSchool]

"script is not work on server it says error line 1"
sorry, should read:

#!/usr/bin/ksh


"also we tried export display but that also not work.

export DISPLAY=:0.0
i tried with above command "

Are you logging in as root using ssh? Are you then "su"ing to oracle? If yes to both, then what does "echo $DISPLAY" when run as root yield?

[Nilesh Naik]

Yes I am login as a root using ssh then suâ ing to oracle.
When I echo $DISPLAY from root it shows {localhost:10.0}
and same when I run from oracle it shows {-bash: DISPLAY: unbound veriable}

[skt_skt]

is the Xserever running?

[Nilesh Naik]

Yes and i checked that by running xclock.

[OldSchool]

so, after su'ing to oracle, enter

export DISPLAY=localhost:10.0

then try xclock. If you get a message about like
"Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
Error: Can't open display: localhost:10.0
Error: Couldn't find per display information"

then you need to authorize the display as described above

[skt_skt]

i had seen simialr error from oracle program? restart the Xsever and relate application( if required).

[Nilesh Naik]

As you mentioned above I saved the file & done all the same but when i run the script ./disp_auth.sh oracle its giving the error for ./disp_auth.sh line 1 !/usr/bin/ksh: No such file or directory

[Vadsys]

Does the first line in your script start with a hash(or pound)-viz # ?

it should be #!/usr/bin/ksh

[Oviwan]

hey

first with root, execute:
xhosts + (maybe no required)

then
su - oracle
export DISPLAY=localhost:10.0
xclock

then if the clock appears it works. so you can try to execute your script.

it would be also helpful if you would provide the content of you script.

I already done this and I get the followed error:

Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
Error: Can't open display: localhost:10.0

I trying to run oracle runInstaller from my Putty.

[Oviwan]

i don't whether a X session can be run by putty.

but usually you have to connect with exceed or cygwin etc..

cygwin:

[Nilesh Naik]

I also tryed Cygwin buti get same error mseg.

Hi,

What about Xmanager

this is very good product...you can download and work without exporting display at all.

Try while issue resolved....

[Deepak Kr]

>>>Error: Can't open display: localhost:10.0


Why are you using 10.0 here....have you tried with other display...

like 3.0 or 4.0 etc..

[Deepak Kr]

Hi nilesh,

Try this now!!

Login using root and go to ssh_config under opt/ssh/etc/ssh_config

check if you see

ForwardX11Trusted yes

If you find it "no" then set it to "yes"

Also

ForwardX11 yes

Regds....Deepak

[Nilesh Naik]

I tryed Xmanager tools and it works thanks.

[Oviwan]

so if the answers were helpful don't forget to say thanks with hp points.

[Deepak Kr]

Good to hear that now you are able to get it work.

Cheers!!

Nilesh said:"Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
Error: Can't open display: localhost:10.0"

that's the error noted in previous posts along with the fix for it. it indicates that oracle *wasn't*" properly authorized to use the display. As xclock worked before the su, the display variable is fine. Properly fixing the xauth file would / should resolve the problem.
