Why do we need Queue mechanism in XI
Hi,
What is the use of Queues in XI message processing.???
Why do we Look into SM58 in IDOC Posting. What it says abt???
Explain me in brief nad in general words
Regards
Suman
SM58 is used to monitor RFC communication which is basically Idocs coming (inbound) and going (outbound) from the SAP system
SM58 - Transactional RFC (Remote Function Call). BW uses tRFC for data transmission and this transaction will list all the RFCs associated with a request. You can get details like target system, status, RFC id, etc. so that you can check in BW whether there was any errror with the RFC.
SM58 is used to monitor the data packets coming into BW from the R3 side or from BW to BW. You can see every data packet through this transaction. So if any data packet is stuck in the source system, then you can basically see that from this transaction and take the necessary action to push it through. TRFC is nothing but Transactional RFC which connects the 2 systems and is used for sending data from one system to other.
It'll be there for any load, full or delta coming from the source system. You can push them manually by clicking on the data packet and then hitting key F6. you can do that for most of the errors, but for say that the background user password has changed or if the user is locked, you need to change that first then reprocess.

Why do i need to recompile...please help ?
Hi Folks,
Iam in a big debate here concernning a moderately complex application. The application contains 20-30 EJbs and some war files. jar files and they are all packaged into a EAR file.
Please Note: We have to upgrade our weblogic servers from WLS8.1 -sp2 > WLS81-SP3. We have like 10 others application been upgraded, all we did is , just point the application to the new JDK and weblogic version....and they worked superbly !!!
But this application, didn't get deployed when we upgraded. Then i told them (actually one of my friend working in that application team and i told him to recompile the code and give back to me---just for our testing purpose), to recompile the code with newer jdk version. He finally did, and the application get deployed.
Now, the big problem is that the application team(managers and all of them) does not want to do it. .....they are saying that we have to do LOT of work and we will not do RECOMPILE (officially) ...UNLESS and UNTILL if you give them concrete details of "WHY".
Now since iam in server support team, i have very little idea for how to tell that they need this recompilation because of following reasons:
1 ?
2 ?
3 ?
could anybody please tell me some reasons , why an application needs to recompiled for this type of an upgrade ?
your guesses would be ok for me.....
Thanks a ton,
sangitaBTW, this is the exception that i get: ...hey, iam on HP box, and not on SUN box. The other application were upgraded on SUN box only,,,,would that make any difference ???
This is the exception:

Why do we need a Home Interface?
Hi Guys,
I am new to EJB. i am some questions.
1) Why do we need a Homeinterface?
2) Where does container generated classes for both the interface located(assume we have 2 machine, one is client and another is server)
In RMI we hv stubs and skeletons located in client and server side....similarly how it is designed in EJB?
Thanks & Regards
-vijayIn EJB3.0 the home interface has been removed. The purpose of home interface was to serve as a factory for finding/creating/destroying an enterprise bean instance. I am not sure why exactly the architects of ejb created a home interface. May be they thought its better to have a clear seperation of responsibilities, that is home interface for the above said purpose and component interface (a.k.a remote interface) for executing the business methods. Also you need to understand that the client never deals directly with a bean instance. The client always calls a bean's home or remote interface methods whose execution is delegated to the actual bean instance. This mechanism provided more flexibility for the container in creating and managing enterprise bean's instances. Hope this helps.

Why does WebUtil needs AS configurations?
If we have to only attache the WebUtil.PLL and sub-class the webutil.olb to the form and place the frmwebutil.jar in the \%Oracle Dev Home%\forms\java then why do we need such a complicated set-up in the app server (like signing with JACOB which I really don't understand)? Do we have to install any Java components in the DB also?
Can anybody explain to me what happens when a 10g Release 2 Form tries to read an Excel sheet from the client machine? In simple steps can you plese explan what WebUtil components are called and where those components are (client/app server/DB machine)? How does the application server come into play when a Form reads from an Excel sheet in the client machine because the Excel sheet is in the client machine and NOT in the app. server or DB machine?
Please pardon my ignorence in this. I tried reading the documentation (PDFs and web-pages) but I could not figure how it works.
Edited by: user12240205 on Apr 29, 2011 6:06 AMthen why do we need such a complicated set-up in the app server (like signing with JACOB which I really don't understand)?JACOB stands for JAva-COm Bridge. This is the mechanism by which Oracle Forms is able to interact with the Client workstation and call Windows COM Automation components. Without the JACOB library (.jar) WebUtil would not work. You have to sign the jacob.jar because your application is deployed over the web.
Do we have to install any Java components in the DB also?No - you only need the WebUtil database package.
Can anybody explain to me what happens when a 10g Release 2 Form tries to read an Excel sheet from the client machine?Forms uses the Webutil Client_OLE2 package to communicate with Excel using Windows COM methods. As I mentioned above, without the JACOB library, WebUtil would not be able to communicate with Excel using COM.
In simple steps can you plese explan what WebUtil components are called and where those components are (client/app server/DB machine)?Rather than explain each step, there are numerous demo's on the internet and in Oracle's Forms Demos that demonstrate how to use WebUtil. It is also a very common topic in the Forums. I recommend you look at WebUtil - A Simplified guide to understanding WebUtil. Also take a look at Forms: How to Read an Excel file into a Form for an example of how to interact with Excel.
How does the application server come into play when a Form reads from an Excel sheet in the client machine because the Excel sheet is in the client machine and NOT in the app. server or DB machine?{qoute}The Application Server (AS) is simply the transport mechanism to deliver the JACOB Java Library to the Client. When a Forms interacts with Excel - everything occurs on the client. Depending on what you are attempting to do, the AS may never be involved with a WebUtil transaction on the client. Now, if you need to upload a file or store a client image in the database then the AS and the Database server would become involved.
Hope this helps,

Why do we need WS Addressing??
What is WS Addressing? Why do we need in SOA??? Give me Some Examples guys
WS-Addressing is a transport-neutral mechanism by which web services communicate addressing information. SOAP envelopes & headers used within web services for transporting data throught transport layers like HTTP does not possess intelligence to specify unique addressing information. Hence, WS-Addressing evolved which contained endpoint references (EPR) and message information headers for identification. This information is processed independently of the transport mechanism or application.
For reference on WS-Addressing click here
By default, Oracle BPEL PM implements WS-Addressing for all asynchronous web service calls, hence we don't have to explicitly implement identification relationship between the incoming & outgoing messages.
Hope this will help

Hi,
We have an integration project where we need a queuing mechanism. Transactions come in during the day. Some of them should be transformed and routed to one of the target systems, but some of them need to be pause and first be routed during the evening/night. Which options do we have in the SOA Suite? If we use BPEL we could use the Wait Activity, but what if we have thousands of waiting transactions? Are there other options? What about the ESB?
I was thinking about using an AQ queue, but if SOA has something we can use I rather use that.
Regards PeteThanks,
The customer has bought the SOA Suite so that is the platform we have to use. I am a database guy, so all this mocking about in the middle tier makes me itch :-)
There is going to be a bunch of integrations but the first one has XML messages coming in from several systems. The messages have to be transformed to another XML format and send to one system. The receiving system has a performance problem so we have to queue all messages and then make sure that we only send XX messages per minute/hour. So event if we use the Wait activity in BPEL we still have a problem with making sure that only a certain number of messages are send to the receiving system. I can see a straight forward way of doing this with a table or AQ. Are the any help in BPEL/ESB?
I know that BPEL can handle thousands of transactions; I am just a bit worried about having thousands of transactions that has to be dehydrated to the database and woken up now and then to check if it is ok to proceed.

PeteThanks Pete. I would go with Pete's suggestion.
Pete,
For your case, the main overhead is dehydration and loading the instance..you can tweak the minBPELWait property in domain.xml so the engine won't dehydrate for smaller waits.. instead it would do thread.sleep( ). the default value is set to 2 seconds.
<property id="minBPELWait">
<name>Minimum BPEL activity wait seconds</name>
<value>2</value>
<comment><![CDATA[
This property sets the minimum BPEL activity wait.
If the wait time for a wait activity or an onAlarm branch of a pick activity is less than the value defined here, the wait is ignored. This property is only applicable to durable processes. The default value is 2 seconds.

Archiving cds and why do i need id3 tags
here comes another one of those questions looking at which codec to use to store music.....i also have tag questions.....
i'm about to (re-)rip my cd collection and looking at some info re codecs and id3 tags
now.....i believe i understand the benefits of alac (lower file sizes, keeping id3 tags, lossless compression) v wav(no compression)
however (and for some out there) if we just entertain the fact that wav may have some minute benefit for me depending on my questions and answers given.....and yes i know wav and alac will sound the same to the human ear - i accept that as a given of lossless compression ......
points i'd like to outline:
i am looking to rip my cds, firstly and mostly, for an archiving purpose!! purpose numero uno!!
i could well want to re-create cds with these archived records in the future
size of files is of no concern to me at all
i'm using a mac nowadays
i will convert most of these files, where needed, to use with a portable music player (i'm not bothered with having, say a wav file and then also converting and having an alac file, as crazy as that sounds)
this is where i ask for info re the benefits of embedded tags that are found in alac:
are these tags that important?
where do they come into play in ripping and later converting music?
are these uses just bells and whistles that have no benefit to my needs?
if i rip cds to wav (or aiff), say, using itunes, will cd info and track listings be available on the downloading database (eg itunes) to name these wav files?
if i then ensure these song files are kept under the album's folder, have i just done what tags do? surely not. that is all i have needed in the past.
this is where i feel i may be really missing what id tags (can) do
are tags more than just managing song files and where they belong and where they have come from?
is it just a convenience of not personally managing your song files (as per previous paragraph)?
(in the past i had ripped cds to mp3 codec. i think i used "cd rip" or something like that on my pc.
my mp3 files were individually named and sorted and kept under album folders under artist name folders.
apart form the very odd occasion all track and album info i needed was found on a database that was attached to the ripping software.
i never had a problem managing/maintaining these files and folders.)
i welcome some enlightenment on some of my questions above and other info that may be relevant
and yes, i understand that music will sound the same as a wav file or alac file - but humour me re using wav and tell me why i need id3 tags
i guess the crux of it is:
why do i need id3 tags?
does my managing of my song file in the album folder do what tags do?
what problems/shortcomings/headaches may i encounter by not having those tags if i use wav as opposed to alac?
what do i not know about these little buggers?
what codec is best for my purpose of archiving and re creating of cds (for playing in cd players)
thanks in advance for your input and any clarity that i may experience through this

excuse my long windedness (i have spent some time editing this entry)Crows2012 wrote:
as mentioned earlier if i just have songs (wav) in album folders, when i import these albums into itunes, do you know if these will come up under AN album with their file names purely using my filename setup (but with no artwork)?
Yes, iTunes will read the filename, such as "Track 1" or something else and display it. But nothing else. No Album or Artist.
so the tracks will remain grouped as an album based on their initial folder and the albums and tracks as per file name?
Crows2012 wrote:
also, does aiff have limitations (apart from the full size of the file)?
I'm not sure I understand what you mean. For all practical purposes AIFF and WAV are exactly the same thing. They're just file containers.
i thought that i had read somewhere that aiff tags could run into some issues with its tags - ie may not always be transferred 100% accurately with certain players (or hardware maybe)
Crows2012 wrote:
and how do these codecs work re-creating an album for the purposes of playing in a cd player? - this is a crucial question for the purpose of my archiving/backup of CDs THEMSELVES
That's actually going to depend on what burning software you use. Once you rip the tracks to whatever file container you choose (WAV/AIFF/ALAC) you'll never really exactly re-create the album. But for archiving purposes all three file containers will do what you want, which is to create a lossless archive. AIFF has the advantage of supporting embedded ID3, which ALAC has the additional advantage of the files also being about half the size of AIFF/WAV files.
i was thinking that maybe wav was able to recreate an album (in effect duplicate one) if my cd was lost or damaged in the future. i was thinking this IF when ripping to wav everything is unchanged (unless there is other data on the original cd). and maybe only possible with wav. the purpose for this would be to play recreated cds on my cd player
any idea on this one?
(i havent looked too thoroughly on this angle but i'll keep googling on this one)
much appreciate all info thus far

Why do I need to connect my Ipad mini with my Mac Book Pro via iCloud? I don't have iCloud on my MacBook Pro and only intend to use the mini to check e-mail and use Garage Band and Photo Booth for song writing when traveling . . .
Thanks Community! I solved the problem. In fact it was not a problem but lack of understanding. These guys at Apple are way ahead in thir thinking. I will try to explain as short as I can.
In Lion, ihe Prefferences/Display show only two choices: 6-7 steps of resolution and some color tab. No two screens, no two display to overlap, nothing for us to do. "That was the problem"! Everything is automatic.
When I connected the HDMI cable to the Miniport into a T-bolt slot, the TV screen showed the "spiral galaxy" how Zyriab is calling it. In fact he gave me the best clue. That shows the connection is good. But where is the Mac Book image?
You have to drag it to the right out of the Mac Book display area, and "voila!" it will continue on the TV screen. The same with the mouse pointer, push it out ofthe Mac Book display area and you see it on the TV sreen. Good image, you can keep the max resolution, etc. The sound is still on the Book's speakers. I have to figure that out.
Thank everybody, especialy Zyriab, ne was the closest.
High regards to everybody -

Why do I need to start up Screen Sharing twice to get it to work ?
I have an Intel Mac Mini connected to my TV, so I started using Screen Sharing from my MacBook Pro to be able to work on it when others were watching TV.
Both Macs used to have OSX 10.5 Leopard, and everything worked fine.
Now they both have OSX 10.6 Snow Leopard, and whenever I startup Screen Sharing, the connection-windows asking for my Name & Password comes up properly, but then it hangs... it stays in "Connecting..." for ever (litteraly).
I'm not able to quit or force-quit the connection-window by then, so it stays in view...
(Screen Sharing isn't even listed in the force-quit list as a running app)
but...
when I just try Screen Sharing again, I get connection immediately and it seems to work flawlessly...
...it's just that the connection-window is impossible to quit...
it stays in view an is really annoying...
this looks really crappy...
can anyone tell me why I do need to startup Screen Sharing twice to get it to work ?
Is this a bug ?
(If so : please apple fix this a.s.a.p.)
...or am I doing something wrong ?
(if so : what am I doing wrong ? and how can I get rid of this annoying screen ?)
Thank you for your kind reply.
Toon.Bit's October and this really annoying problem still exists !
the unnamed screensharing-loginwindow keeps "Connecting...", and I'm unable to shut it down...
...even after my screen sharing session is over
...even force-quitting is impossible (this 'app' just isn't showing up in the force-quit-window...)
please Apple - fix this ; under 10.5 it was working great !
Does anyone have any idea how to fix this ?
(besides restarting my Mac)
Thanks !

This is a question about exception handling. I have to build a diary application that lets you save reminders on particular dates using xml. Just to make it a little tougher, I was not allowed to use the Calendar class. This is the code I wrote:

}My question is, why does the exceptions in the example code not need to be caught? And why do I have to catch the exceptions in my code? Several exceptions are thrown in the example code, but there is no catch statement.
Thanks for any advice!!Since your question didn't come with any relevant details, and since you have huge steaming piles of irrelevant code, all I can give is a general answer to "Why do I need to catch this exception?"
[url http://java.sun.com/docs/books/tutorial/essential/exceptions/index.html]Exception tutorial at http://java.sun.com/docs/books/tutorial/essential/exceptions/index.html
Here's a quick overview of exceptions:
The base class for all exceptions is Throwable. Java provides Exception and Error that extend Throwable. RuntimeException (and many others) extend Exception.
RuntimeException and its descendants, and Error and its descendants, are called unchecked exceptions. Everything else is a checked exception.
If your method, or any method it calls, can throw a checked exception, then your method must either catch that exception, or declare that your method throws that exception. This way, when I call your method, I know at compile time what can possibly go wrong and I can decide whether to handle it or just bubble it up to my caller. Catching a given exception also catches all that exception's descendants. Declaring that you throw a given exception means that you might throw that exception or any of its descendants.
Unchecked exceptions (RuntimeException, Error, and their descendants) are not subject to those restrictions. Any method can throw any unchecked exception at any time without declaring it. This is because unchecked exceptions are either the sign of a coding error (RuntimeException), which is totally preventable and should be fixed rather than handled by the code that encounters it, or a problem in the VM, which in general can not be predicted or handled. -
I know that this is a very basic question, but I have been asked why do we need to have a new MOLGA for every country; what I know of is:
1. Is the standard method of supporting multi-country (Global) HCM. MOLGA is central to the SAP HCM solution.
2. The correct screens are shown in PA30 to maintain the personnel data in the correct formats for social security or equivalent number, form of address, addresses, bank details and so on.
3. The correct infotypes can be made available by MOLGA, where there are particular pieces of information required on a country by country basis u2013 therefore reducing the risk of non compliance
4. Correct ESS screens are available
5. Payroll available by country. For example the payroll program is run per country using the MOLGA PC00_Mxx_calc, where xx is the country code, therefore for GB it is PC00_M08_calc.
But apparently this is not a compelling enough reason - can anyone help with more good reasons?Hi Marina
hope you are doing good.
Globalized firms need Integrated systems with Independent County Legal, Labor, Taxation ,Currency , Language requirements.
So a Global ERP System will help to achieve this without compromising the local requirements.
I shared my experience , hope it sound sane.

What am I doing wrong with the isNew() method? and why do I need the other methods?
I have coded an include jsp like this.
<%@page language="Java"%>
<%@page import="javax.servlet.http.HttpSession"%>
<%!
String iContextPath;
String iCommonPath;
String iImagesPath;
%>
<%
iContextPath = request.getContextPath();
iCommonPath = iContextPath + "/common";
iImagesPath = iCommonPath + "/images";
System.err.println(" here ");
HttpSession thisSession = request.getSession( false );
if( thisSession.isNew() ){
System.err.println("isnew");
response.sendRedirect( iContextPath + "/common/login.jsp" );
%>
Now I also have a redirect.jsp in the root of an application that contains
this.
<html>
<body>
<%
System.err.println("Redirecting at this time from the root");
response.sendRedirect( request.getContextPath() + "/secureArea/");
%>
</body>
</html>
And I have a logout.java servlet that looks like this.
package com.pch.epics;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import weblogic.servlet.security.ServletAuthentication;
public class Logout extends HttpServlet{
private static final String CONTENT_TYPE = "text/html";
//Initialize global variables
public void init() throws ServletException{
//Process the HTTP Get request
public void doGet( HttpServletRequest request, HttpServletResponse
response ) throws ServletException, IOException{
String username = "";
if( request.getUserPrincipal() == null ){
username = "Unknown";
} else {
username = request.getUserPrincipal().getName();
System.err.println( "ePics logging out '" + username + "'" );
request.getSession( false ).invalidate();
ServletAuthentication.logout( request );
ServletAuthentication.invalidateAll( request );
ServletAuthentication.killCookie( request );
response.sendRedirect( request.getContextPath() );
//Process the HTTP Post request
public void doPost( HttpServletRequest request, HttpServletResponse
response ) throws ServletException, IOException{
doGet( request, response );
//Clean up resources
public void destroy(){
First of all, why won't the isNew() report a new session in the server log?
EVERY request coming in says it's an old request (ie it's not new). The
J2EE Applications and BEA WebLogic Server book from BEA says this should
work.
My second question is why do I need to do those three lines from
ServletAuthentication to logout a user? Ok, maybe I'm from the MS world,
but that seems excessive, especially since I've already done a
session.invalidate() right before it, but the bea docs say I'm required to
do all four!
When you invalidate a session. You invalidate the session of the web
application that your jsp/servlet is part of. It is possible to have more
than one web application on WLS and have them share a authentication info.
While these applications share authentication they do not share their
sessions so because of that calling session invalidate does not kill all the
sessions. ServletAuthentication is needed to kill all the sessions and do a
complete logout from WLS.
