Dear Linux and SAP Expert:
I am facing a problem, I want to install Oracle 9i on SUSE Linux, I need to use ora<sid> to install it, but when I use xhost +, i am prompted "xhost +: unable to display"
I have already set the followings:

What can I do???How can I solve this problem?
Really really thanks for your all reply

Hi Hisashi Glay,
You can try the following senario also if you are taking VNC over windows machine.
Install the vnc server package i.e vnc-server-x.x.x. and download the vnc client for windows i.e. UltraVNC Win32 Viewer 1.0.1.
After the above activity do the following configuration at server end.
run the command as a root or ora<SID>. Whose graphical login you required.
In our senarion we use ora<SID>.
run the command
vncserver
vncpasswd #This is to set the password for that vnc login
after run the vncserver change the following setting in xstartup file
cat ~/.vnc/xstartup
#!/bin/sh
Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x241010 -ls -title "$VNCDESKTOP Desktop" &
twm &
chage the below line as follows.
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
#[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
Afte this changes kill the vncserver once
vncserver -kill :1
than start the vnc server again.
vncserver
Everything is done now use the gui of that server from windows client machine
hostname:1 or IP Address:1
Hopefully this will resolve your problem
Thanks and Regards,

Xhost: unable to open display...

Greetings. I'm having install issues, and google is leading me to believe its due to the DISPLAY variable. The problem is all commands related to xhost, export DISPLAY, etc. all generate the error:
xhost: unable to open display "myIPAddress:0.0"
Any ideas?
Thanks in advance!!!

DISPLAY=:0
Way too easy.

It sounds like you are issuing the xhost on the remote computer (after ssh). (If so, why are you doing that?)
The sequence is:
- Log on to a computer that has an X11 screen that you want to use for display
- Open a terminal on this local screen ... do not su
- Issue xhost
- Note the 'DISPLAY' information
- ssh to the computer/user that has the software to be run
- issue 'export DISPLAY=' and add the hostname ':' and display info
- run the command

Unable to Display This Video

Watching videos at nbcnews.com, some days get message: Unable to display this video. The ads always display, but not the stories. And only some days. Why?

You're right that when the apps are available they work better than Safari. I can't find one for The Last Word, which is my favorite show. And like I said, the problem seems to be intermittent, so I don't believe that its a Flash issue. Actually, it's been a couple of days now since I could view The Last Word, so perhaps they are doing something different with their coding than before.
Thanks for your suggestions... They are helpful. :-)

Unable to display a PDF image on the page - Mac 10.6

Hi,
Running an iMac with 10.6.8 and Indesign 5.0.4. Just wanting to export a PDF as per usual via File > Export function. However, I keep getting the error message, "Unable to display a PDF image on the page'. No idea what this is and have never seen this error before. The only info on the internet reveals error code 0x2511(9489).
I've deleted prefs, closed down and re-opened Indesign and even restarted the computer. I've also re-linked the images contained in the document and even created a new document and set it up the same, but still the same problem. Investigating further, other Indesign documents still export properly.
The only ones that don't export are 2 documents, both giving this same error message. Both documents are ones where a client has sent a PDF, I've imported into two of these into an 2-page A4 Indesign document (each PDF is 48MB each) and then just added a text layer (using Times) which is properly installed on the computer. I basically have to 'update' course dates for the client and add PDF to the website, all very basic.
I've tried importing a jpeg and other PDFs into the file (replacing the existing ones) and they export fine.
All my software is legal and I've exported this document before now in exactly the same File > Export without any problems (under 10.5 and 10.6).
OK... I've just imported the offending PDFs into Acrobat, optimized and shrunk the file size, re-imported back to Indesign and the PDF export works fine. So it seems InDesign / PDF Export doesn't like large imported PDFs? I think they were originally exported from Publisher, so maybe that's the problem or a file conflict somehow.
Any ideas on the culprit? I've googled it, searched these forums and Apple discussions and haven't found anything. Although I've found a workaround, I do get large files to import and then export. Thanks for any help
Steve

It does sound like a problem with the original PDF files the client sent you. You can check how they were made in Acrobat Pro from the Additional MetaData button on the Description tab of the document properties dialog. It will be under Advanced at the bottom of the list when the metadata opens.
You might be able to salvage them by running the optimzer and not changing the size, or just doing a Save As in Acrobat.

Unable to display tree view; Error when parsing an XML document (Premature end of file.)

Hi folks,
I am using a cascaded mapping in my OM. I have a graphical mapping followed by the Java mapping. It is a flat file to IDOC mapping. Everything works fine in Dev but when I transport the same objects to QA, the Operation mapping though it doesn't fail in ESR testing tool, gives the following message and there is no output generated for the same payload which is successfully tested in DEV. Please advise on what could be the possible reasons.
Unable to display tree view; Error when parsing an XML document (Premature end of file.)

kalyan,
There seems to be an invalid xml payload which causes this error in ESR not generating the tree view. Please find the similar error screenshot and rectify the payload.

JavaMapping in PI 7.1 Error:Unable to display tree view; Error when parsing

hi,
i get by testing in PI 7.1 (operation mapping) this ERROR:
"Unable to display tree view; Error when parsing an XML document (Content is not allowed in prolog.)"
this is my java-programm-code:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import com.sap.aii.mapping.api.StreamTransformation;
import java.io.*;
import java.util.Map;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
/*IMPORT statement imports the specified classes and its methods into the program */
/Every Java mapping program must implement the interface StreamTransformation and its methods execute() and setParameter() and extend the class DefaultHandler./
public class Mapping extends DefaultHandler implements StreamTransformation {
Below is the declaration for all the variables we are going to use in the
subsequent methods.
     private Map map;
     private OutputStream out;
     private boolean input1 = false;
     private boolean input2 = false;
     private int number1;
     private int number2;
     private int addvalue;
     private int mulvalue;
     private int subvalue;
     String lineEnd = System.getProperty("line.separator");
setParamater() method is used to store the mapping object in the variable
"map"
     public void setParameter(Map param) {
          map = param;
     public void execute(InputStream in, OutputStream out)
               throws com.sap.aii.mapping.api.StreamTransformationException {
          DefaultHandler handler = this;

               SAXParser saxParser = factory.newSAXParser();

               saxParser.parse(in, handler);
          } catch (Throwable t) {
               t.printStackTrace();
As seen above execute() method has two parameters "in" of type
InputStream and "out" of type OutputStream. First we get a new instance
of SAXParserFactory and from this one we create a new Instance of
SAXParser. To the Parse Method of SaxParser, we pass two parameters,
inputstream "in" and the class variable "handler".
Method "write" is a user defined method, which is used to write the
string "s" to the outpurstream "out".
     private void write(String s) throws SAXException {
          try {
               out.write(s.getBytes());
               out.flush();
          } catch (IOException e) {
               throw new SAXException("I/O error", e);

          write("");
          try {
               out.flush();
          } catch (IOException e) {
               throw new SAXException("I/O error", e);
     public void startElement(String namespaceURI, String sName, String qName,
               Attributes attrs) throws SAXException {
          String eName = sName;

in developer studio 7.1 i dont get error.
this happens by testing the mapping-programm in ESR.
can somebody help me please?

Make sure that the xml created out after the java mapping is a valid xml with only one root node.

MS Notepad unable to display the Chinese characters I type and display them as squares

MS Notepad is unable to display the Chinese characters I type and display them as squares. But when I copy those squares on notepad to Wordpad or MS Word, they display the Chinese characters just fine. I've no idea why those Chinese characters I type can't display properly on notepad. I check the font of the notepad and it's the default. I've another Windows Vista desktop computer which has notepad of the similar setting and display Chinese characters just fine. Both are using Chinese (Simplified) - Microsoft Pinyin New Experience Input Style to input those characters. But I don't understand why my Windows 7 is facing this problem.

Hi,
Notepad is a very simple text editor BUT it will work if you use the SAME language in Windows. Please try:
1. go to control panel, click "Clock, Language, and Region"
2. click "Change location" under the "Region" section
3. go to the "administrative" tab, then click "change system locale...", then select "Chinese".
Regards.

Messenger Express 6 Unable to display embedded images

Hi
Messenger Expresss seems tob unable to display embedded images (gif or jpeg) in the form cid:image.gif and some hosted images. In reference to the the cid:image.gif , when I open the email get an error from the browser that states "Warning: the application cid must be lauched to view this file." or something close to that. It gives me a choice of opening "cid" or canceling. There is also a check box "remember my choice for all files." which I choose and then I get an email full of broken image links.
I've tried this in Firefox and IE the routine is a bit different but the result is the same. No images displayed.
I also used a netflix email I recieved.. some of the images displayed some did not. The ones that did display were from www.netflix.com some of the others hosted on an image server somewhere in the netflix namespace did not.
I'm at a loss. If anyone can shed some light on this I'd be very thankful
Erik

I was speaking about what client created the original mail messate.
The "error message" isn't very useful. Is the mail message itself is badly formed, then the problem lies with the client that created it.
You should be able to tell from the headers of the message.
If you have the message file on disk, examine it with a text editor. "Message file on disk" means the original file, as stored on the server as a xxx.msg file, not what any client might save to a local disk.
When we work these kinds of things as tech support cases, we start out with this file.
I have no idea what gmail does, so that's not really relevant.
Your IMAP client may be better at displaying badly formed messages than webmail is.

Regarding CRM EIC where i am unable to display HCM processes in IC Appl

Hello Colleagues,
I am working on CRM_EIC.
There is an issue where i am unable to display HCM Processes in the IC application.
I have launched the application from CRM system thru the t-code "WUI", and selected the business role "IC_EIC_AGENT".
Given the pernr and confirmed and in "service request" in "Business Context"tab, selected "HCM Process" and click on New,
it connects to the ERP system for the HR processes data , it doesn't display the list of processes.
CRM System:QOM/508
ERP system: QV5/004
Can you please help regarding the above issue.
Thanks in advance.
Kind Regards,
Gayathri.

Hi Vinod,
Thanks much for the response. I had not looked at the sap note earlier on, saw it after your reply.
However, we are not using IE7.0 yet. I would like to mention here that independent of the portal, when I launch the CRM IC Webclient on any browser, it appears well and good, but when launched from within Enterprise Portal, page appears minus the toolbar. Do you have any idea/pointers on the same. However I plan to get the notes correction done and would like to thank you for an useful answer.
Pls do let me know if there is anything missing on EP 7.0 or CRM 2007 that needs to be done additionally.
Thanks and regards,
Anupama
