Hi,
from my Windows Workstation I can connect with PUTTY to an AIX 6.1 unix server.
On AIX via PUTTY I run DBCA which has a grphical interface.
Then :
#DISPLAY=local_host:0.0 ; export DISPLAY
$(hostname) $(whoami):/appli/oracle/product/10.2.0/db_1/bin#dbca
_X11TransSocketINETConnect() can't get address for local_host:6000: Hostname and service name not provided or found
How to rectify this error ?
Thank you.
What do you mean by "local_host" ?
If it is the name of a host that is local on your network, then you need to add that machine to the DNS or /etc/hosts so that it is recognised.
If you mean "localhost", then you have made a typo.
Cheers.
Thank you. I rectified :
#DISPLAY=localhost:0.0 ; export DISPLAY
$(hostname) $(whoami):/appli/oracle#dbca
Exception in thread "main"
Any idea ?
On the other hand should I install any software (X server for Windows for example : X-Ming) on my workstation ?
Regards.
Ah right. Yes, you will definitely need an X-Windows emulator for your workstation. If you then access the AIX box using their emulator it is usual that your DISPLAY variable will be set correctly, and any Xauthority security, and you should then be able to start the graphical appllication.
I installed Xming but :
In putty (for DBCA nothing happens):
DISPLAY=localhost:0.0 ; export DISPLAY
$(hostname) $(whoami):/appli/oracle#dbca
Exception in thread "main" $(hostname) $(whoami):/appli/oracle#dbca
$(hostname) $(whoami):/appli/oracle#xclock
Error: Can't open display: localhost:0.0
Regards.
No...."localhost" means the X-Windows display on the host you are logged into.
Usually you would set the DISPLAY to be the IP address of the workstation you are logged in from. For example your workstation may be 192.168.1.1 and the AIX server you are logged into is 192.168.1.2. In this instance you would set your DISPLAY=192.168.1.1:0
Again, usually the X-Windows emulation software will give you an option to set the DISPLAY variable automatically. Also X-Windows security is important. Again the emulator should sort that for you (look for options using Xauthority or xauth).
Hi,
big123456, did you resolve this?
Please log into your server and without running anything else, type:
echo $DISPLAY
And tell me what it says.
You'll have to enable X11 forwarding for the PuTTY connection. In the configuration dialog, select Connection -> SSH -> X11, and check the "Enable X11 forwarding" option. Afterwards, when you enter the command echo $DISPLAY you should see some output similar to DISPLAY=localhost:10.0
Thank you.
root:/root#echo $DISPLAY
root:/root#su - oracle
`hostname`@oracle$echo $DISPLAY
`hostname`@oracle$
When you log in, your display information is set. When you su, that information gets lost. It is possible though to make this work.
Here is the script I use. You will have to modify it. But hopefully you can understand what needs to be done:

Notice the xauth comamnds.
In your own .profile, you must run the above script.
ie:
/etc/profile.ssh.check
When I log in, I see:
Checking for SSH connection....yes!
Examples:
In general:
Get the key, then re-export your display:
xauth -bi merge /tmp/.profile.ssh.check.AIX.purdym.display_key.905454
DISPLAY=localhost:15.0; export DISPLAY
-=OR=-
you can run this script: /tmp/.profile.ssh.check.AIX.purdym.setup_display.905454
As Root:
. /tmp/.profile.ssh.check.AIX.purdym.setup_display.905454
As Sybase:

su - sybase

Notice how you have to log in, su to root, change the perms on your key file, su to the next user, then source the key file.
Here is a full example:

The questions :
for oracle user (as I do : su - oracle)
1-is DISPLAY=IP_OF_MYWindowsWorkStation:X.X
2-How to find correct XX (in line above) ?
Regards.
The reason for scripting this mess and to answer your question: it's not that simple.
Simply knowing the display of your workstation is not good enough. Another user can not write to your display, unless you give them permission.
I will answer your question, your display doesn't change.
Notice in my example, that as myself: DISPLAY=localhost16:0
Then AFTER root imports my X key (as I call it): DISPLAY=localhost16:0
Then AFTER root grant permissions,su to sybase, ...: DISPLAY=localhost16:0
Please log in, and with out su'ing, type:
echo $DISPLAY
If DISPLAY is not set, X11 tunneling is not configured. Fix this first.
Thanks.
In my PUTTY , I enabled X11 forwarding and now I have
echo $DISPLAY
localhost:11.0
And Xclock sends a clock windwos on my workstation.
Thanks and Regards.
