Http push (push data onto browser without refreshing)

Can any one please give refrences or usecases where we can implement a http push (server side) using java technology

It looks like you have more than one problems so it might be good to separate them out.
Issue 1 - Logging on to BusinessObjects
You say that when you try log on to the BO Platform you get the error message there is no central management server running on port 6400. I'm assuming you are trying to do this from the Dashboard designer.
Does it work when you try to log on from the web browser?
Make sure that you enter the correct system name in the system field when trying to log on from Designer. If you are unsure, either check what system name is used when you log on from your browser or check with your BO administrator.
Issue 2 - Passing values to a child dashboard
If you try to preview the dashboard in the designer, remember that the swf loader doesn't work in preview mode, so whatever you are trying to display won't be visible.
First of all you need to have 2 separate flash files that works independently of each other. The one that you are planning to use as a child flash, make sure that you create the flash variables so you can pass variables to it and use them to filter your data if that is your requirement. But hold off on that for now.
When you have 2 working flash files, save them both to the BI Launch Pad (or InfoView if you are on 3.1) and make sure they both work there. Then get the opendocument url for the child dashboard and try to open it in your browser directly using this url. If that works, use the same url in the swf viewer in the parent dashboard, save the parent dashboard back to BI Launch Pad and open it. It should now work.
Let me know if you have any problems with these steps.
Cheers,
Josh

Data fetch from table without Refresh and without using tab key.

hi Friends,
I have a problem i want to extract data from table without Refresh into text field without using Tab key. when i'll enter any value in a text field then corressponding value should come in to corressponding textfield without using Tab Key.
eg. when i enter emp_id 101 in a text field then the first_name and last_name ,adress should come in to corressponding text fields without refresh and without using Tab key.
How Can I do this.
Thanks
Manoj

Hi Manoj,
I assume that this is similar to: Data fetch without Refresh rather than Re: Value of one textfield should come into another textfield Without Using TAB ?
If so, the only change you need to make on the first one is to use "onkeyup" instead of "onchange" in the item's "HTML Form Element Attributes" setting.
Note, however, that the user must move away from the item at some point (for example, to click a button), so the onchange will be triggered anyway.

Hi,
Firstly, you would find it easier not to use x.something in the tag names in your process (I'm not sure if they are allowed, but I would avoid the dots anyway!). So:
DECLARE
vCLASSID VARCHAR2(100);
vSECTION VARCHAR2(100);
vFNAME VARCHAR2(100);
vLNAME VARCHAR2(100);
BEGIN
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
SELECT C.CLASS_ID,C.SECTION,S.F_NAME INTO vCLASSID, vSECTION, vFNAME,vLNAME FROM CLASS_RECORD C INNER JOIN STUDENT_PERSONAL_DETAILS S ON
C.STUDENT_ID = S.STUDENT_ID WHERE C.STUDENT_ID = :STUDENTID
htp.prn('<DATA>');
htp.prn('<CLASS_ID VALUE="' || vCLASSID || '"></CLASS_ID>');
htp.prn('<SECTION VALUE="' || vSECTION || '"></SECTION>');
htp.prn('<F_NAME VALUE="' || vFNAME || '"></F_NAME>');
htp.prn('<L_NAME VALUE="' || vLNAME || '"></L_NAME>');
EXCEPTION WHEN OTHERS THEN
htp.prn('<DATA>');
htp.prn('<CLASS_ID VALUE="No such CLASS NAME!"></CLASS_ID>');
htp.prn('<SECTION VALUE="No such SECTION!"></SECTION>');
htp.prn('<F_NAME VALUE="No such First Name!"></F_NAME>');
htp.prn('<L_NAME VALUE="No such First Name!"></L_NAME>');
htp.prn('</DATA>');
END;I've also completed the EXCEPTION output as well so that both possibilities use DATA and /DATA
This does assume that you have an Application Item called STUDENTID and that your Application Process is called SCS and is an "On Demand" process
Now, the javascript... Firstly, you can't include dots in the var names as this identifies a property or attribute or function of an item (for example, document.location.href). Secondly, you should use the same upper/lower case text for the XML tag names as you used in the process - if you stick with uppercase throughout it is easy to remember. So, I've removed the dots and made the XML tag references uppercase:
<script type="text/javascript">
function getEmployeeInfo(filter)
var xml = null;
var get = new htmldb_Get(null, $v('pFlowId'), 'APPLICATION_PROCESS=SCS', 0);
get.add('STUDENTID', filter.value);
ret = get.get('XML');
if(ret)
    var class_idItems = ret.getElementsByTagName("CLASS_ID");
    if (class_idItems)
      var class_id = document.getElementById("P314_CLASS_ID");
      class_id.value = class_idItems[0].getAttribute("VALUE");
    var sectionItems = ret.getElementsByTagName("SECTION");
    if (sectionItems)
      var section = document.getElementById("P314_SECTION");
      section.value = sectionItems[0].getAttribute("VALUE");
    var f_nameItems = ret.getElementsByTagName("F_NAME");
    if (f_nameItems)
      var f_name = document.getElementById("P314_STUDENT_NAME");
      f_name.value = f_nameItems[0].getAttribute("VALUE");
    var l_nameItems = ret.getElementsByTagName("L_NAME");
    if (l_nameItems)
      var l_name = document.getElementById("P314_STUDENT_NAME");
      l_name.value = l_nameItems[0].getAttribute("VALUE");
get = null;
</script>If you try those, does it now work?

How to flush / push htp buffer to browser

+I posted this question on the SQL / PL/SQL forum (How to flush / push htp buffer to browser) Since this is a web centric forum I thought I'd post here as well.+
Is there a way to flush or push the htp buffer to the browser?
For example, suppose you had a procedure.
htp.htmlopen;
htp.p('hello');
htp.helpclose;
-- No more HTML to print
-- Still some more code to runAt the top of the procedure you print some HTML code. You want it sent right away to the user but you still have some other PL/SQL code to run. Right now it appears as though the entire procedure needs to finish before the HTML is sent to the browser.
The reason I'm doing this is to test a new HTML 5 technique which allows for servers to push data to client. The thing is that I need to be able to force / push the contents of the buffer to the browser while keeping the procedure running.
Thank you,
Martin

Hi Paul,
Thanks for the link. I just read thought it. Wondering if by any chance things have changed in mod_plsql since then...

Servlet to push unsolicited data to clients

Hi,
I have a servlet in which messages are XML documents in the body of HTTP requests/responses. A client sends in the HTTP/XML request, the servlet delegates processing to some service provider, gets the result, and sends it back to the client as XML in the body of the response. That all works fine.
I now want to extend the servlet to handle the situation where unsolicited data (in XML) is pushed to the client. It is not a broadcast system, the unsolicited data would be targeted at a specific client (or maybe a small number of clients).
Any suggestions of the best way to approach this kind of facility?
Thanks,
Paul

The servlet does have some knowledge of clients through session information. All clients are required to log in so the servlet can store any information it wants about each client with a session. Of course, that doesnt give the servlet the ability to open a connection to a client.
I was hoping there might be some way for the client to open a persistent connection to the servlet which would be recorded in the session data. The servlet could then use this connection to push XML data to the client at arbitrary times.
In this system when I say client I don't mean a browser. The primary purpose of this interface is to allow other systems to access services.

How to push System-Data to the SLD ? NWA 7.11

How can i push the data from a J2EE-system to the SLD that is connected/configured in the NWA (Destinations) ?
In older versions of NWA there's being a 'collect and send'-button...
best regards
Christoph

The SLD_DataSupplier and SLD_Client destinations should be set in NWA -> Configuration Management -> Security Management -> Destinations
Next under Configuration Management -> Infrastructure Management -> SLD Data Supplier Configuration. Collect and Send exists to send the data to SLD.

Hi Manoj,
You have to make an Ajax call to display data without refreshing the page. Search this forum for Ajax and you can find lots of related posts. This link might help too. http://www.dba-oracle.com/t_html_db_apex_ajax_application_express.htm

How can we update the date&time without refreshing the page

Hi friends,
I have a jsp page. In that there is Date and Time. The date and time should be updated for every one minute without refresh the page(dynamically).
Its urgent for me
Thanks
Mallik

hello friend ru looking at date and time @ client side frm the server side if it is all about the client side date i don't think there is use of AJAX triggers and rendering the view by modifying the dom...
here is an example for you..
<%@ page language="java"%>
<HTML>
<HEAD>
<SCRIPT language="JavaScript">
function startclock()
var thetime=new Date();
var nhours=thetime.getHours();
var nmins=thetime.getMinutes();
var nsecn=thetime.getSeconds();
var nday=thetime.getDay();
var nmonth=thetime.getMonth();
var ntoday=thetime.getDate();
var nyear=thetime.getYear();
var AorP=" ";
if (nhours>=12)
    AorP="P.M.";
else
    AorP="A.M.";
if (nhours>=13)
    nhours-=12;
if (nhours==0)
   nhours=12;
if (nsecn<10)
nsecn="0"+nsecn;
if (nmins<10)
nmins="0"+nmins;
if (nday==0)
nday="Sunday";
if (nday==1)
nday="Monday";
if (nday==2)
nday="Tuesday";
if (nday==3)
nday="Wednesday";
if (nday==4)
nday="Thursday";
if (nday==5)
nday="Friday";
if (nday==6)
nday="Saturday";
nmonth+=1;
if (nyear<=99)
nyear= "19"+nyear;
if ((nyear>99) && (nyear<2000))
nyear+=1900;
this.document.getElementById("clockspot").innerHTML = "<b>"+nhours+": "+nmins+": "+nsecn+" "+AorP+" "+nday+", "+nmonth+"/"+ntoday+"/"+nyear+"</b>";
setTimeout('startclock()',1000);
</SCRIPT>
</HEAD>
<BODY>
<div id="clockspot"></div>
<SCRIPT language="JavaScript">
startclock();
</SCRIPT>
</BODY>
</HTML>hope this might help :)

Thanks.This is an error from SQL Server being passed back to Oracle so you can see the problem.
What it is saying is that you are trying to insert (or update) data to a database view and that view contains a column that is either a constant (literal) value or is derived (a calculation, formula or string concatenation etc.).
As such, you can't insert or update data on that column because it has nowhere to go on the database table(s) that underly the view.

How to push the data from PSA to Data Target in 3.5 version

Hi Experts,
I'm currently working on BI 7. I have some master data load being maintained in 3.5 version.
The infopackage has an option to load the data to psa and data target when extracted.
I want to stage the data at PSA only.
Later I want to trigger it to the target.
In 7 version we use DTP but I'm not very sure what should I do here.
Can anyone please help me to push the data to the target please using 3.5 version.
Thanks

Hi pathak,
Thanks for your reply. I'm able to do it.
Can you please tell me how do I filter the load to target.
We have filter in DTP where i can restrict the load.
Do we have any option in 3.5.
Please advice.
Thanks

Best way to push change data from sql server to windows/web application

i apologized that i do not know should i ask this question in this forum or not.
i have win apps which will load all data initially from db and display through grid but from the next time when any data will change in db or any data will be inserted newly in db then only change or newly inserted data need to be pushed from db side to
my win apps. now only sql dependency class is coming to my mind but there is a problem regarding sql dependency class that it notify client but do not say which data is updated or inserted.
so i am looking for best guidance and easy way to achieve my task. what will be the best way to push data from sql server to win or web client.
there is two issue
1) how to determine data change or data insert. i guess that can be handle by trigger
2) next tough part is how very easily push those data from sql server end to win apps end.
so looking for expert guide. thanks

Hello,
Yes, you can create DML trigger on INSERT and UPDATE to get the changed data into a temp table. And then query the temp table from application.
If you are use SQL Server 2008 or later version, you can also try to use
Change data capture, which
can track insert, update, and delete activity that is applied to a SQL Server table and store the changed values on the Change Table.

LifeCycle Form Server :- My form is rendering as pdf in the browser without displaying data sometim

LifeCycle Form Server :- My form is rendering as pdf in the browser without displaying data sometimes within data fields, and at other times it will display data. The form consistently displays data when rendered in HTML.
We display the forms in a browser either HTML or PDF format based on the user selection. But the behavior of PDF format is not consistent. Sometimes it renders properly and sometimes the form renders without data.
Dose any one experienced this issue?
Any help would be greatly appreciated.
Thanks in advance,
RK

I have been seeing the same issue, but haven't been able to find a fix for it yet. So any info would be appreciated here too.
Thanks

Pushing the data through proxy to ECC Developement as well as to quality

Hi all,
I need to push the data throug proxy from XI to ECC(developement system) at the same time to ECC(quality system)
What do we need to do from XI?
Thank you

In most setups you would have a DEV ECC box which points to DEV PI box and a QUAL ECC which points to a QUAL PI box . So in SPROXY of ECC you would be able to see the interfaces from either DEV or QUAL .
So, my assumtion is that you will not be able to do this unless both ECC boxes point to the same PI box. If tht is the case, you need to just add both ECC Bus Sys in the receiver determination and create 2 interface determinations.

Can anyone confirm the date used for pushing the data into AR interface table? Is it abse don Actual ship date or scheduled ship date?

Can anyone confirm the date used for pushing the data into AR interface table? Is it abse don Actual ship date or scheduled ship date? We are facing a scenario where trx date is lower than the actual ship to which logically sounds incorrect.
Appreciate any quick response around this.

Hi,
Transaction date will be your autoinvoice master program submission level date (If you haven't setup any logic.
Please check the program level default date, if user enter old date ststem will pick the same.
Customer is trying to set the value of the profile OM:Set receivables transaction date as current date for non-shippable lines at the responsiblity level. System does not set the transaction date to current date in ra_interface_lines_all.
CAUSE
Customer has used the functionality in R11i. But after the upgrade to R12, the system functions differently than R11i.
SOLUTION
1.Ensure that there are no scheduled workflow background process run.
2.Set the profile "OM: Set Receivables Transaction Date as Current Date for Non-Shippable Lines" at Responsibility level only as Yes.
3.Now switch the responsibility to which the profile is set.
4.Create order for Non-Shippable Lines and progress it to invoicing.
5.Ensure that the 'workflow background process' concurrent program is run in the same responsibility and this line is considered in it.
6.Now check if the 'SHIP_DATE_ACTUAL' is populated to ra_interface_lines_all

How to insert a new field without refreshing the data

Hi,
I have data of 3 years in a cube. I have to enhance a new field in that cube and i want the data will come from now onwards. I dont wanna have the data for the past 3 years.
Can anyone tell me how i can load the data of that field into the cube without refreshing the cube as cube has too much data.
Roma

Hi Roma,
It depend up on whether you are adding Cgharacteristic or Key figure. If you are adding key figure then no need to worry.
Just create the new keyfigure, add this in all your data flow and activate all the objects and assign proper transformation.
from next load you will get data for this field.
If you are addign data the this is a bit difficult than key figure. addign characteristic is nothing but you are making changes to your cube dimensions.
when you are changing your cube dimensions, you should delete the data before you transport the objects.
You can try once to transport the objects with out deleting data. If it fails then you have to delete the data from Cube.

Venkatesh.
