Hello ALL,

I was reading this topic:
http://www.orafaq.com/forum/?t=rview&goto=260444#msg_num_11
And I have been surprised when ThomasG wrote about installing and managing Oracle on a text-based only linux server:
ThomasG
Basicly yes, but ...

- Java is present on the installation media, so you don't have to install it beforehand.

- The XWindow environment doesn't have to be on the server itself, you can connect with ssh/telnet from a remote workstation which has X installed, and use that X Server (Either a *nix box or MS Windows with Cygwin, Exceed or some other X server running)



Then... my understanding is:
1) having a fedora box with text-installed mode only;
2) having a remote workstation with X Server installed;
May I use X Server from remote workstation to connect to fedora text box and install oracle?

3) What are the basic requirements on text-fedora7 to have oracle installed on it?
4) Does anyone may point me a tutorial/url to accomplish this task?
Thank you,

mson77

Hello All,

My scenario:
1) I have a Fedora 7 linux server. This server is text-based only installation.
No X-Windows, no-Gnome and no-KDE installed;
2) I have an other machine with MS Windows plus CYGWIN installed;
3) Both are networked and no firewall running;
4) From Cygwin I am able to "ssh" Fedora7.

What I want:
1) I want install Oracle10gr2 on Fedora7. I mean... on a linux with no X, no
Gnome and no KDE.

My background:
I always known that to install oracle database one should have graphic
environment and java... both installed on the linux target server. BUT I have
read that:
a) java is not necessary as oracle installation already comes with java;
b) graphic environment could be used from some remote host;

Guidance needed:
Having my scenario as above stated... how to proceed?
I mean in term of: xhost and export DISPLAY settings at least.

I have tried but with no sucess... no sure if is config problems or cygwin
installation problem or variables setting... ?!?!?!

I have googled also... and now I ask for help in this house.

Regards,


mson77

Welcome to OraPros mson77!

What you are trying to do can be accomplished. I have not worked on
Fedora7/CYGWIN but do the same exact thing on Solaris all the time, in fact
none of our solaris boxes have "heads" we always export DISPLAY to our
workstations.

From what I understand you have MS Windows with CYGWIN (with X server) and you
want to install ORACLE on remote linux box using your PC's monitor to drive the
installer.

Here's what needs to happen:


ON CYGWIN


1. make sure X server is started

2. find out the ID of display and ID of screen started by the X server:
Cygwin-x faq - display and screen explained

3. take a note of your IP address


ON LINUX

1. export DISPLAY variable to:
ip_addr:display_id.screen_id

where:
ip_addr = IP address of your MS-WIN pc with CYGWIN X server
display_id = display ID of your X server (typically 0)
screen_id = screen ID of your X server (typically 0)

example KSH/BASH:
$ DISPLAY=207.71.117.101:0.0; export DISPLAY

example CSH:
% setenv DISPLAY 207.71.117.101:0.0

2. from the same session where you set DISPLAY run xclock as a test
you should be able to see XCLOCK windows on your PC

Let me know If this doesn't work -- I'll try to install CYGWIN on my PC and
test it here.

Hello Vitaliy,

Thank you for your very kind attention, reply and information.
I will test... and I will post the results here.

I got a chance to test Cygwin-X today - it worked fine, a bit slow over SSH
tunnel but it works as far as I can tell. Here's a write up I put together:

Download And Run:
http://cygwin.com/setup.exe

At the "Cygwin Setup" screen click Next

(o) install from the internet
click Next

Root Directory: C:\cygwin
(o) All USERS (o) Unix / binary
click Next

Local Package Dir: C:\Program Files\cygwin
click Next

(o) Direct Connection
click Next

Download Site: select first one
click Next

At the "Cygwin Packages" Window click Next
runs for a while (30 minutes?)
click Finish

Launch Cygwin-X:

run C:\cygwin\usr\X11R6\bin\startxwin.bat

(this should startup a white window on your PC)

At this point your Xterm is ON and you can start serving remote clients. There
are two options you have:

Option #1 - SSH Tunnel

open Putty create new
SSH session and setup X11 Forwarding:

Connection ->
SSH ->
Tunnels
[x] Enable X11 forwarding
X display location: localhost:0.0

on the linux server make sure that X11 tunneling is enabled by sshd

bash-2.05# pwd
/opt/OBSDssh/etc
bash-2.05# cat ssh_config
Host *
ForwardAgent yes
ForwardX11 yes
VerifyHostKeyDNS yes

you might be able to use this instead of VerifyHostKeyDNS?:

X11UseLocalhost yes


connect to the host and make sure DISPLAY is set to:

callisto.portal-> echo $DISPLAY
localhost:10.0

NOTE: SSH automatically sets up DISPLAY to localhost:10.0 OR
localhost:11.0 or localhost:12.0 depending on how many
users have Xforwarding enabled and on the system

test XTERM by running xclock which should pop-up on your PC

Once you have xclock working you can now run Oracle Installer. Just remember
that SSH tunnel / X11 forwarding does not work if you SSH as root and then SU
to oracle - you need to SSH as oracle in the first place.

Option #2 - manually export DISPLAY

Alternatively you can skip SSH tunnel / X11 forwarding if both PC and Linux
boxes are on the same network and can talk to each other directly, to do this
simply startup Xterm on your PC:

Launch Cygwin-X:

run C:\cygwin\usr\X11R6\bin\startxwin.bat

(this should startup a white window on your PC)

then SSH or TELNET to linux box SU to oracle and export DISPLAY to your PC's
ip_Addr:0.0, example:

# su - oracle
$ DISPLAY=207.71.117.177:0.0;export DISPLAY
$ xclock

I forgot to mention that if you use Option #2 you will need to add your linux
box's IP address/name to your XTERM's access list, here's how to do it:

From the Xterm window allow linux host to run on your xterm:

$ /usr/X11R6/bin/xhost linuxhost
linuxhost being added to access control list
