Oracle runInstaller DISPLAY error on SUSE EL 10 SP4

So the other day I was installing Oracle 11g R2 Client on SUSE Enterprise linux 10 SP4 that I got the following error:

oracle@devsuse1:/tmp/newclient/client> ./runInstaller
Starting Oracle Universal Installer...

Checking Temp space: must be greater than 120 MB.   Actual 72192 MB    Passed
Checking swap space: must be greater than 150 MB.   Actual 2055 MB    Passed
Checking monitor: must be configured to display at least 256 colors
    >>> Could not execute auto check for display colors using command /usr/X11R6/bin/xdpyinfo. Check if the DISPLAY variable is set.    Failed <<<<

So after googling around the following seems to work for me:

I launched a new terminal window and did the following:


anyuser@devsuse1:~> su - root
Password:
devsuse1:~ # xhost +
access control disabled, clients can connect from any host
devsuse1:~ # su - oracle
oracle@devsuse1:~> export DISPLAY=:0.0
oracle@devsuse1:~> cd /tmp/client
oracle@devsuse1:/tmp/client> ./runInstaller
Starting Oracle Universal Installer...

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2012-09-16_05-49-58PM. Please wait ...oracle@devsuse1:/tmp/client>

After that the Oracle UI launched successfully and I was able to proceed.


On Solaris 10 Sparc the following seems to work like this for me:

I was logging into the Sun Box using the VNC Viewer Free Edition, but every I tried to  launch the runInstaller.sh as the oracle user I would the the same error as before. So I connected to the Sun Box using the root user... launched the terminal as root

# /usr/openwin/bin/xclock (to check if xclock windows launches which it did)
# /usr/openwin/bin/xhost +
access control disabled, client can connect from any host
# su - oracle
$ cd /tmp/database
$./runInstaller

after this the OUI launched successfully for the oracle user.

PRTG with 30 Free sensors :)

I've been using the freeware version to monitor our bandwidth usage on the lan and it is great with the amount of options available and the reports that can be generated, but freeware version only came with 10 sensors... now for limited time you can upgrade to 30 sensors.  You can find out more about the software @ http://www.paessler.com/prtg.
