Load balancing 10g forms - Connection from new browser window not supported

Load balancing 10g forms - Connection from new browser window not supported
We're experimenting with using webcache to load balance between multiple applications servers running OC4J forms processes.
We currently have one machine with infrastructure and mid-tier (BI & Forms) installed, which is being used for the webcache functionality, this is load balancing between 2 other servers each of which just have the mid-tier (BI & Forms) installation
In order to get this to work, I had to follow the instructions in the Forms deployment guide : http://download-uk.oracle.com/docs/cd/B14099_11/web.1012/b14032/tuning.htm#sthref707
The main gist of this is that you need to set the following in the orion-web.xml file in order that the sessions are maintained:
<session-tracking
cookies="enabled">
</session-tracking>
This all works fine in most cases.
The problem I am having is if I do one of the following on the client machine:
1) From IE6 / IE7 run a copy of a forms application. Then open a new window using the "New Window" menu option, and attempt to run another forms application.
2) In IE7 or Firefox 2.0 open a copy of the forms application, and then open a new tab and try and open another forms application.
If I try either of these I get a FRM-92101 error, and the following is displayed in the java console:
oracle.forms.net.ConnectionException: Connection from new browser window not supported
From trawling various forums (including metalink and otn) it looks like a problem with the way coockies are handled.
Unfortunately the usual workaround is to ensure that the session tracking option in the orion-web.xml file is disabled.
The problem is that I need this enabled in order for the load balancing to work.
Does anyone know of any other workarounds or patches that might help resolve this?
We're using Application server 10.1.2.0.2 running on windows 2003 servers.

You were right. Carriage returns were stopping it from working (the document is laid out over separate lines, so I assumed it would make no difference...).
I've now managed to get it so the forms at least run, but they are all being run in the forms OC4J instance on the same machine as the OHS.
Has anyone actually managed to get this to work, or am I doing something wrong?
I did wonder if using an OHS instance on a machine with no forms installation would make any difference?
I had raised a support call via metalink on this subject, but they eventually came to the conclusion that the only way to do this is with a hardware load balancer (Despite several documents suggesting that webcache is the way to go (including the forms deployment manual)).
I'm at the point now of giving up and writing some custom scripts to do the job instead...

New Browser Window not working on My Mac Intel pro

I have set a behavior in Dreamweaver CS3 to open a new
browser window to a set size and to only show scroll bars if
needed. I have left all other attributes unchecked. This is not
working for me. Can you tell me how to make a new browser window to
my settings using the behaviors in Dreamweaver CS3? I do all the
steps right. what do I do when I follow all the steps for setting
up a new browser window correctly and it doesn't work!? The new
browser window never pops up even when i use an image map. The
Behavior is not working correctly and I even re-installed
Dreamweaver CS3. I am on an intel based mac pro. Running Firefox
version 3 and Safari 3.1.2 on Leopard. I have done this several
times before and it has worked. but that was before Leopard. Here
is my code:
<area shape="rect" coords="4,3,78,77" href="#"
onClick="MM_openBrWindow('images/02.jpg','','width=378,height=504')">
The only way I can get it to halfway work is add it into the
link area
on the properties panel. The window will then open but not to
the
specified size.?
please advise as this is taking a long time to figure out!?

This is an unusual way to go about doing this. Typically you
simply put
the thumbnails up on the page rather than combining them into
a collage
and then adding imagemaps to that.
Nevertheless, it can be done.
You have code like this:
<area shape="rect" coords="0,0,80,80" href="images/12.jpg"
target="_blank"
onClick="MM_openBrWindow('images/12.jpg','','width=378,height=504')">
Try adding
;return false
to each like this:
<area shape="rect" coords="0,0,80,80" href="images/12.jpg"
target="_blank"
onClick="MM_openBrWindow('images/12.jpg','','width=378,height=504');return
false">

Dreamweaver - Chrome open a video in a new browser window not working

Hi guys, i'm pretty novice to dreamweaver and i've putting a site together recently...
One thing i am trying to do is open a video in a new browser window when the button is clicked upon.
I have done what i thought i needed to do this, and in safari and other browsers this works fine. In Google Chrome however this doesn't seem to want to work and rather then opening and playing the video it just automatically starts to download it.
I'm sure it is a simple fix and i apologise for the thread all about it but any help would be appreciated.

Opening a new browser window not working.

Hi,
I have created a webpart which uses the following line of code to open a new window and close the old one when a certain condition is met:
Page.ClientScript.RegisterStartupScript(GetType(),
"hwa",
"myWin=window.self;window.open('"
+ QA_URL + "','_blank');myWin.close();",
true);
This code works in the test environment, but when I try it in the production encvironment, I am receiving a message "A referral was returned from the server/" and the new window is not
being opened.
A note, that there are two configuration values being pulled from web.config which exisit in the production environment. One of them is the ldap information to look up a user and the other is the
url that should be opened in the new window. Does anyone know why this is not happening? Https exists in both the test and the production environment.
thanks
Sherazad

Hi,
According to your post, an error occurred when you opened a new window using JavaScript.
We can do as follows:
1. Check the LDAP configure in the web.config file.

http://mundeep.wordpress.com/2008/07/17/a-referral-was-returned-from-the-server/
2.Try to set the SPSite.UserAccountDirectoryPath property.
PS C:> Set-SPSite -Identity http://brokensite.contoso.com -UserAccountDirectoryPath “”
3. Check the ULS log by the following link:

Run same 9i forms servlet in different browser windows

Hi all,
I'm using Oracle9iAS Forms Service to deploy the forms. The problem that I have, is that I'm not able to run the same forms 9i servlet in two different browser windows.
I'm able to run the 9i test form with the following URL in browser window one: http://HOST:PORT/forms90/f90servlet
When I then try to run the same URL in a second browser window I get the following error:
FRM-92050: Failed to connect to the Server: /forms90/l90servlet:-1

New browser window from jspx site

I use the following commandMenuItem
<af:commandMenuItem text="#{res['pob.menu.help']}"
icon="/images/help.gif"
action="GlobalHelp"
immediate="true"/>
GlobalHelp is /app/Help.pdf
and i want to open it in a new browser window.
I test useWindow, windowHeight, windowWidth but it don't help me.
Any help is appreciated.

Hi, RadoK
How can we use <af:goButton> instead of <af:goMenuItem> or <af:goLink> to achieve the same? I tried use EL in the destination for <af:goButton> but it doesn't work.
What I like to do is
1. opening a page in a new browse window (not like those modal window produced by <af:commandbutton>)
2. pass some request parameters dynamically to the page to be opened.
3. the page is invoked from a command button.
I tried <af:goLink> and it works OK for destination with EL but It is not a button. My command must be shown as a button as it is included in a group of other buttons.
I tried capture the image of a button with desired text and nested this as <af:objectImage> in <af:goLink>. However, when I run the application, the text from the image doesn't look alike that from a goButton or commandButton.
Any suggestion?

Outputting Servlet information to a new browser window

I have a simple form that has a few input text fields and a button. When the button is clicked, the information is submitted to a servlet that uses the information to generate XML and display it on the browser window.
My question is that is it possible to output the XML to a new browser window not the one where the information was submitted from?
Example, I submit some information, a new window pops up displaying the XML. The form window remains as is and outputs a submitted message.
Any code would be appreciated.
Thanks
Rizwan

well thats realy not a servlet q, but a html/jsp q..
your form submit should go to the same page as the form resides on..
in your servlet you process and prepare the response
in your formpage you should detect when a submit has taken place (request.getParam... some variable added in your response prepare
if this is the case, use java script to open a new page (also posting your response information)

Opening a new browser window from flash

Does anyone know of a method fo opening a link in a new
window in firefox from within flash that isn't blocked by the popup
blocker. It seems like the security in FF 2.0.0.6 (I'm on 2.0.0.11)
has been tightened to prevent any _blank or window.open calls from
flash getting through. I've tried the standard getURL, fscommand
and ExternalInterface call to a javascript window.open method.
Nothing now works.
I understand the need for the popup blockers, but this is a
legitimate popup only invoked on user interaction (click) - the
same window.open call in an onClick event outside of flash works
fine and I guess it is blocked from within flash because there is
no way of knowing if the call is invoked from user interaction or
automatically - but seems a shame.
So any other way of getting a new browser window to open from
within flash in firefox?

Use target="_blank" in your form declaration.<FORM METHOD=POST ACTION="someAction" TARGET="_blank">The _blank keyword tells the browser to load the results in a new window.
If you need more control over your window (size, address bar, etc.) you'll need to use javascript.<SCRIPT>
function submitForm(windowName){
   newWin = window.open("",windowName, "menubar=no,resizable=no,...");
   document.myForm.target = windowName;
   document.myForm.submit();
</SCRIPT>
<FORM NAME="myForm" METHOD=POST ACTION="some.jsp" TARGET="">
<INPUT TYPE=BUTTON VALUE="Submit" onclick="submitForm();">
</FORM>

Open discoverer report in new browser window and without connections page

Hi All,
We are using Oracle 11g Discoverer 11.1.1.4. Requirement is to open the discoverer report in a new browser window and without connections page.
When we are running discoverer reports with this parameters we unwantedly get the connections page of the discoverer plus which we don't want.
Went through the documentation given in this page and followed it still the issue persists, and i see couple of threads with my issue and no updates.
This excerpt is from the documentation available in the link
" _plus_popup=true and framedisplaystyle=embedded launches Discoverer Plus in a new pop-up browser window that contains the Plus applet embedded in it "
http://www.art2dec.com/documentation/docs/oas10g1012/linux/bi.1012/b13918/urlstart.htm
and Here is what we use to invoke our reports.
http://ipaddress:port/discoverer/plus?cn=cf_123&_plus_popup=TRUE&framedisplaystyle=EMBEDDED&wb=disc_wb_1
Request the forum users from PRO discoverer group to help me out of this issue and expect a good discussion on this.
Thanks in advance

Conditionally opening a new browser window from a JSP page

When the user clicks on a button in my JSP page, I'd like to launch a new browser and display certain things in that browser window while leaving the original browser window open. The new browser should only be displayed if certain conditions are met.
My thought was to invoke a javascript method in 'onLoad' which would determine if the new window needs to be launched.
This is kinda what my page looks like:
<jsp:root version="1.2" ................>
    <jsp:directive.page import="java.util.*, com.test.Configuration" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"/>
    <f:view>
     <ui:body binding="#{Page1.body1}" id="body1" onLoad="launchWindow();">
     </ui:body>
   </f:view>
   <script type="text/javascript">
        function launchWindow(){
         if (Configuration.openWindow()) {
          window.open("hello.jsp", "newWindow", 'toolbar,width=400,height=400');
    </script>
</jsp:root>
My problem is that the call to "Configuration.openWindow()" does not resolve correctly. If I remove that call and simply make a call to "window.open()" all works. But once I put the condition in, nothing happens. I do not see an exception in my browser window but a new browser window does not open.
Is my syntax correct. Can I make a call to the static method 'openWindow()' in my class 'Configuration.java'.
I posted this same query on the JSF forum but received now replies. My question is more suited to the JSP forum and hence I'm posting this question here.
thanks,
tsc

I have made some changes so that I do not directly access the 'Configuration' class in my javascript.
I have a hidden field on my form and when the user clicks the button, in my back bean, I set a value for the hidden field. In the javascript function 'launchWindow()' I check if a value has been set for the hidden field and if yes, I open a new window.
<ui:body binding="#{Page1.body1}" id="body1" onLoad="launchWindow(document.forms[0]);">
<h:inputText id="hiddenField" value="#{formBean.hiddenValue}" />
<script type="text/javascript">
        function launchWindow(form){
            alert("in lw");
            var test = form["form1:hiddenField"].value;
            alert("got test");
            if (test != "")
                window.open("hello.jsp", "newWindow", 'toolbar,width=400,height=400');
            alert ("done test");
</script>When my page is first loaded, the launchWindow() is called and all the alerts popup as expected.
When I click on the button (the back bean sets the value on the hidden field), my page is reloaded but this time its blank.
Any ideas as to why this maybe the case?
thanks,
tsc

My ipod touch broke then replaced it with a new one. I already dloaded iOS5 on the old one. When I connected my new unit it says it won't load the previous back because the new one is not up to date... Do I really have to download iOS5 again?

Yes, you have to update the iPod in order to retore from backup. The iOS on the "new" has to be aequal to r greater than on the iPod from which the backup was made. The iOS downloads are unique to an iDevice and model (the one for a 3G iPod will not work for a 4G iPod).

Opening of an ADF applcn in a new browser window from another ADF applcn.

The requirement is in the form of a usecase below, can you please let us know how could we resolve this.
Let us consider we have two ADF applications A and B. Once ADF application A is rendered, in one of the pages of Application A there is a link which takes us to Application B. We want to open the ADF application B in a new browser window.
There is one more restriction here, the first time the link in Application A is clicked it should bring up the Appliciation B in a new window say W2 , later on if the person clicks multiple links from Application A it should refresh the exisiting open window W2 with the Application B. i.e we do not want multiple windows to come up for a single link.
I do see the commandlink has a usewindow=true ,this is the functionality we want. basically the first time the link is clicked a new window should pop up, later on every click of the command link we want to refresh the same open window which had come up the first time the command link was clicked.
Edited by: user504058 on Nov 9, 2010 6:05 AM

I did try using the Golink with targetFrame with all the values "_blank", "_parent", "_self" , "_top". with targetFrame value set as _blank it brings up multiple windows.
Let me be more clearer, I do have application A in browser window say W1 and when i click a link from Application A present in browser window W1 the Application B should open up in new browser Window W2. And further on simaltaneous clicks on the link in Application1 should only refresh the Window2 with Application B.
i.e, at any given time i want only two windows to be present i.e, W1 and W2.

Load balancing to JDBC connection pool

from http://e-docs.bea.com/wls/docs61///////cluster/overview.html
"WebLogic Server provides limited load balancing support for managing JDBC
connections in a cluster. If you create an identical JDBC DataSource in each
clustered WebLogic Server instance and configure those DataSources to use
different connection pools, the cluster can support load balancing for JDBC
connections. Note, however, that WebLogic Server provides no special load
balancing policies for accessing connection pools. If one of your connection
pools runs out of JDBC connections, the load balancing algorithm may still
direct connection requests to the empty pool."
How is this different from creating one connection pool with one datasource
and targetting the cluster. Are they talking about load-balancing to
different databases, or different servers in WLS. from a servlet or from a
client side app?
Can anyone elaborate?
Thanks in advance.

hi,
without knowing the entire set of requirements or the motivation behind doing this, a few words from me
this is usually done transparently to the applications server, that is having eg. Oracle instances mirroring eachother for extreme high-availability requirements.
1. I would have taken the liberty of calling this business funcionality and let my middleware do the implementation of this. The most elegant solution would probably be to call the master DB for the CUD operation, then post a message to a queue letting the slave DB be updated asynchronously. If the message could not be sent, throw an exception and have the entire operation rolled back.
If however this must happen realtime and transactions must be consistent, there are a few points to consider. And the quieing bit would not work.
if this is something that should be done for all Create, Update and Delete operations, an intercepting JDBC driver could do the trick. Although there are all sorts of different problems that could arise from this, for starters, at least one of the DBMS involved here should be XA compliant. If the entire transaction should be XA compliant, both DBMS must be XA compliant. Next as for the transaction towards the "mirroring" DBMS you would have to do all the transaction stuff your self.
For an example of an intercepting JDBC driver, I found thisone
http://media.datadirect.com/download/docs/jdbc/jdbcref/spy.html
I would guess that there are quite a few more.
