[Resolution] Verify that your DISPLAY environment variable is set correctly,

running the Oracle Installer as a different user or on a different host,
you may need to use the xhost command to ensure that host/user

could you please help here

xhost command retruns unknown command

[ErmanArslansOracleBlog]

Set your DISPLAY env variable accordingly.
give X permission to the OS user that you are using for the installation ( do this with root user and xhost + command)
Then you are good to go.. Retry.

[Satish]

Thanks for the update erman. erpdevelopmentdb is my server name and I have set display erpdevelopmentdb:0.0

How to give X permission

[ErmanArslansOracleBlog]

connect with root.
set the same display env variable
then execute "xhost +" command

[satish]

Thanks for the update erman,we tried it

[root@erpdevelopmentdb ~]# export DISPLAY=erpdevelopmentdb:0.0
[root@erpdevelopmentdb ~]# xhost +
xhost:  unable to open display "erpdevelopmentdb:0.0"

This is the error after setting the display as root and xhost + command

DISPLAY is not set.  Please set the DISPLAY environment variable and try again.
Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:
- For csh:                      %% setenv DISPLAY 192.168.1.128:0.0
- For sh, ksh and bash:         $ DISPLAY=192.168.1.128:0.0; export DISPLAY
Use the following command to see what shell is being used:
echo $SHELL
Use the following command to view the current DISPLAY environment variable setting:
echo $DISPLAY
- Make sure that client users are authorized to connect to the X Server.
To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command:
%% xhost +
To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as 'xclock':
%% <full path to xclock.. see below>
If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance.
Typical path for xclock: /usr/X11R6/bin/xclock
Log: /tmp/OraInstall2018-05-16_06-04-36PM/install2018-05-16_06-04-36PM.log

No X11 DISPLAY variable was set.
Set this variable to a valid value, for example:

set DISPLAY=localhost:0.0

The log(s) can be found here: /tmp/OraInstall2018-05-16_06-04-36PM.
[obiee@erpdevelopmentdb ~]$

[ErmanArslansOracleBlog]

your DISPLAY env variable is still not set Satish...

Please set it properly for your OS user and terminal, use xhost + to give X permission to your OS user and retry.

This is a very clear and basic issue, bytheway.

[satish]

I am sorry erman.pasted earlier logs before setting the display

We have exported the display as you sugsted and below is the error

Instead of setting DISPLAY to erpdevelopmentdb:0.0,we have set it to export DISPLAY=:0

As root:

[root@erpdevelopmentdb ~]# export DISPLAY=:0
[root@erpdevelopmentdb ~]# xhost +

and the error was fixed.what would be the difference between setting DISPLAY to erpdevelopmentdb:0.0 and setting DISPLAY to :0

Thanks for the support

Again,thanks for all the support

There is no errors in the log file that you send me.

As for your DISPLAY related question;

DISPLAY=hostname:displaynumber.screennumber

The hostname specifies the name of the machine to which the display is physically connected. If the hostname is not given, the most efficient way of communicating to a server on the same machine will be used.

The problem you encounter when you set your DISPLAY to hostname:0.0 , is related with your X server configuration.

Unless you have reconfigured your X startup, your X server won't be listening for network connections.
If need TCP, then modify the file /etc/X11/gdm/gdm.conf , set DisallowTCP=false and restart your X server.

So when you add hostname to your DISPLAY env variable (ex: hostname:0.0), it means your clients will connect to your X using TCP..

On the other hand; when you omit "hostname", means that the client should connect using UNIX domain sockets (IPC). -- which is allowed by defaut.

Well.. Setting DISPLAY to :0.0 (without hostname) is okay.. You are already in the same machine where your X runs..You go with that...

[satish]

Thanks erman for letting us understand the things in a clear way.It was unable to launch the GUI screens and the log says "host: erpdevelopmentdb.ttd.com] [nwaddr: 172.16.112.75] [tid: 1] [userId: obiee] [ecid: 0000MDgqcBFBt1GqywaeMG1QzIM1000001,0] Waiting for presentation module to launch." for almost 30min

[ErmanArslansOracleBlog]

This is "not an error" Satish. It is just waiting there. Waiting presentation module to launch
Probably, the error is in somewhere else.. (probably, in some other log file)
probably, the thing that launches presentation module got errors, or it just hangs..

What error you encounter in your installation screen?

[satish]

Dear Erman,

Thanks for the update.

no further actions

[ErmanArslansOracleBlog]

1)Which document are you following for the installation?

2)Did you set your DISPLAY correctly? I mean -> if you set your DISPLAY to wrong X interface, then you might not see the installation screen. That is, those screens will be opened in a different X windows then yours.. (probably, your issue is this one) .. As your DISPLAY is wrong, the installation screens are opening in a different X(VNC ) interface than yours.. So you cannot see them.. Check your DISPLAY accordingly.

[Satish]

Thanks for the update erman. We have killed all the vnc sessions and started a fresh vnc,then ran the same installation command and we are able to see the gui screens

[ErmanArslansOracleBlog]

Good! So it was related with X / DISPLAY Setting as you see.. The installation screens were directed to wrong screens.
So when you killed all the vnc sessions and opened a new one, probably, your DISPLAY setting and vnc port became aligned ,and the problem dissapeared.

[Satish]

Thanks for all the support erman.
