DISPLAY environment variable problem

[Former Member]

Hello gurus,

I want to install SAP ERP 2005 SR2 IDES with oracle on RHEL5.

Server's DISPLAY env. variabe is :0.0 and I chane this variable my_server_ip:0.0 and export it.

after that I start the xclock it gives the error like that:

Error: Can't open display: <my_server_ip>:0.0

so I cannot start ./sapinst correctly.

I read the forum but I cannot solve this problem.

What can I do ? Please help me.

Thanks.

If you are logged on locally on your server and a DISPLAY variable is set don't change it.

Hi Markus,

When I start ./sapinst, it shows this:

[root@REDIDES1SRV IM_LINUX_X86_64]# ./sapinst

and nothing happens, why?

What can I do?

Hi,

Defo looks like your an X window issue from the output you just gave.

If your IP address for the DISPLAY variable is set correctly

on target execute: xhost +

on server make sure that .Xauthority exist ! (if not, search google how to setup)

Hi,

Please check that xclock kind of graphical programs, you are able to execute without any errors. with proper DISPLAY variable settings.

Also check the version of used jdk... "java -fullversion". its there as recommended as in sap note 1172419.

Also check the network settings (entry in /etc/hosts file)...

Hi,

[root@REDIDES1SRV ~]# echo $DISPLAY

:0.0

[root@REDIDES1SRV ~]# xclock

ok. it works

[root@REDIDES1SRV ~]# java -fullversion

java full version "J2RE 1.4.2 IBM build j9xa64142-20090306 (SR13)"

[root@REDIDES1SRV ~]# echo $JAVA_HOME

/opt/IBMJava2-amd64-142

[root@REDIDES1SRV ~]# echo $PATH

/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:/opt/IBMJava2-amd64-142/bin

/etc/hosts

1. Do not remove the following line, or various programs

2. that require network functionality will fail.

127.0.0.1 localhost

::1 localhost6.localdomain6 localhost6

192.168.4.121 REDIDES1SRV.mbis.corp REDIDES1SRV

[root@REDIDES1SRV ~]# hostname

REDIDES1SRV

[root@REDIDES1SRV ~]# hostname -s

REDIDES1SRV

[root@REDIDES1SRV ~]# hostname -f

REDIDES1SRV.mbis.corp

is these wrong?

Thanks.

Hi,

root@REDIDES1SRV ~# echo $DISPLAY
:0.0

Your echo is not bringing back your IP address your DISPLAY has not set properly for some reason.

"If you are logged on locally on your server and a DISPLAY variable is set don't change it." Markus said. So I didnot change DISPLAY env var.

Thanks.

This is correct.

So xclock works, sapinst does not.

Try the following:

mkdir /install
chmod 777 /install
cd /install
rm -rf /tmp/sapinst*
<full-path-to-sapinst>/sapinst

Hi Markus,

I did these:

[root@REDIDES1SRV ~]# mkdir /install

[root@REDIDES1SRV ~]# chmod 777 /install

[root@REDIDES1SRV ~]# cd /install

[root@REDIDES1SRV install]# rm -rf /tmp/sapinst*

This is really strange.

Is your firewall deactivated?

Markus

[Former Member]

Yes Firewall and SELinux disabled.

Thanks.

You use Redhat, right?

Note 1048303 - Red Hat Enterprise Linux 5.x: Installation and upgrade

You need to install additional libraries (see that note).

Thanks

Hi,

Error: Can't open display: <my_server_ip>:0.0

DISPLAY environment variable is set with <host_name>:0.0, where <host_name/host_IP> is the host where the SAPinst GUI is displayed.

Have you tried the following execution...??

-> Login as root

1. xhost +

1. export DISPLAY=<host_name/host_IP>:0.0 (based on used shell, you will have to set/export the variable)

1. xclock

Hi,

First, make sure that you have added host entry in /etc/hosts file for your server as below

<IP Address of your Server>    <Hostname of your server>
127.0.0.1                localhost

Then try again, it should work...

By the way, can we know how you are starting installation ?

I mean from Client system or directly from server itself ?

If you are installing from other system, you should set as

export DISPLAY=<your local host IP>:0.0

Regards.

Hi,

The IP address you have set for DISPLAY is this the servers IP address where SAP will be loaded or your PC's ?

Hi,

*Mark

I use sapinst on server. All processes work on server.

*Rajesh

I added host entry before this problem. So it is ok but it didnot work.

I start the installation on server.

Thanks
