Why do we need ROCANCEL in datasource?

why do we need ROCANCEL in datasource?
many thanks.

Hi,
ROCANCEL filed is one based on which you will come to know whether it is new record or change rec etc.... that is coming in the delta extraction.
N -- New record.
X --- Changed
--- Deleted.
This will be mapped to 0RECORDMODE infoobject in BW based upon which the data is updated to ODS.

Why do we need header datasource?

I just got confused? Why do we need header data table if line items datasource contains all the field of header datasource? Another thing is that should we create different ODS' for each?

Hi George..
Choosing an header or a line item data source depends on the reporting requirements which is the very initial phase in any implementation project.. There, if the requirement is to develop a report at the header level (which will be summarized eg: Reports based on Sales Organization or for a particular Sold to party) then you go in for a Header level data source... but if the requirement is such that the report will have to display each and every line item (detailed eg: all the materials ordered during a sale order creation), then you go in for a line item level datasource...
Hope it clears your doubt..

Why do I need to pass params. to getConnection when using OracleDataSource?

Hi,
I've been experimenting with Tomcat 5.5 and using Oracle proxy sessions. After many false starts, I finally have something working, but I have a question about some of the code.
My setup:
In <catalina_home>/conf/server.xml I have this section:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
username="app1" password="app1" maxActive="20" maxIdle="10"/>
</Context>
In my App directory, web.xml has:
<resource-ref>
<description>DB Connection</description>
<res-ref-name>App1ConnectionPool</res-ref-name>
<res-type>oracle.jdbc.pool.OracleDataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
And finally, my java code:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.driver.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
conn = (OracleConnection ) ds.getConnection("app1","app1");
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "xxx/yyy");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
 conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
//rst = stmt.executeQuery("SELECT 'Success obtaining connection' FROM DUAL");
rst = stmt.executeQuery("SELECT count(*) from sch_header");
if (rst.next()) {
message = "# of NJ schools: " + rst.getString(1);
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
My question concerns this line of code:
conn = (OracleConnection ) ds.getConnection("app1","app1");
Why do I need to pass in the user name/password? Other examples, that I see simply have:
conn = (OracleConnection ) ds.getConnection();
But when I use this code, I get the following error:
java.sql.SQLException: invalid arguments in call

 at oracle.jdbc.pool.OracleDataSource.getConnection(OracleDataSource.java:221)
 at oracle.jdbc.pool.OracleDataSource.getConnection(OracleDataSource.java:165)
 at web.ConnectionPool.init(ConnectionPool.java:32)
... more follows, but I trimmed to keep posting shorter :-)
Is there anyway that I can avoid having to pass the user/password to getConnection()? It seems that I should be able to control the user/password used to establish the connection pool directly in the server.xml file and not have to supply it again in my java code. In earlier experiments when I was using "import java.sql.*" and using it's DataSource, I can use getConnection() without having to pass user/password, but then the Oracle Proxy methods don't work.
I'm a java newbie so I guess that I should be happy that I finally figured out how to get proxy connections working. However it seems that I am missing something and I want this code to be as clean as possible.
If anyone can point me to a better method of using connection pools and proxy sessions, I would appreciate it.
Thanks,
Alan

Hi,
Thanks for the replies.
Avi, I'm not really sure what you are getting at with the setConnectionProperties. I looked at the javadoc and saw that I can specify user/password, but since I'm using a connection pool, shouldn't my Datasource already have that information?
Maro, your comment about not having set the user/password for the Datasource is interesting. Are you referring to setting it in the server.xml configuration file? As you can see I did specify it in addition to setting the URL. In my code example, I'm not having to respecify the URL, but maybe I have a typo in my config file that is causing the username/password not to be read properly??
The other weird thing is that I would have expected to see a pool of connections for user App1 in V$SESSION, but I see nothing. If I use a utility to repeatedly call a JSP page that makes use of my java example, then I do see v$session contain brief sessions for App1 and ADAVEY (proxy). The response time of the JSP seems much quicker than I would have expected if there wasn't some sort of physical connection already established though. Maybe this is just more evidence of not having my server.xml configured properly?
Thanks.

Why do we need 2 JNDI while congifuring DB or OA Adapters

Hi,
i have a question why do we need to have 2 JNDI's while configuring DB or OA adapters. I mean first we create a JDBC connection and specify a JNDI , and again in Deployments -> DBadapter/OAadapter-> we go and configure a JNDI with JDBC name .
Why is it so ?
- Thanks
Shirish

the first one you mentioned is used when creating the jdbc datasource, the jndi is at that moment the identifier which you can use for a lookup of the datasource.
this jndi identifier you then use in the database adapter so it can lookup the datasource information based on the jndi value
so the first one physically creates it and in all the other steps you 'use' the jndi lookup for retrieving it's information
see : http://en.wikipedia.org/wiki/Java_Naming_and_Directory_Interface

Why exactly u need to deactivate and activate in lo extraction?

why exactly u need to deactivate and activate in lo extraction?


Hi 
You won't really be deactivating any extract structure or datasource because it will stop data transfer. However if you change the structure and do not activate it then it will be in modified version (or deactivate state) for system.
 
Hope it helps.

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?

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.B

it'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 !

}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.

Why do I need to use MOLGA?

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.

HT201250 What is Airport Utility and why do I need to access this in order to backup my iMac using Time Machine...PLEASE??

What is Airport Utility and why do I need to access Airport witeless devices in order to backup my iMac using Time Machine...HELP!!! PLEASE??

AirPort Utility is required to configure an Apple AirPort Base Station or Time Capsule.
Time Machine can use a Time Capsule or a locally connected volume. You only need to use AirPort Utility if you are using a Time Capsule.

What are smart mailboxes and why do i need both smart and "normal" ones?

What are smart mailboxes and why do I need both smart and "normal" mailboxes?

Hi Kingoftypos,
Thanks for that clarification. So, now it appears that the ultimate purpose of a Smart Mailbox is to point to all emails that meet the criteria in a single place, so if they are spread among several mailboxes, you will be able to see them all together. Here is an article from Apple that describes it:
A Smart Mailbox displays in one location messages that are stored in other mailboxes, so you don’t have to move messages between mailboxes. The messages displayed by a Smart Mailbox are based on criteria you define, and are automatically updated to include new messages that match your criteria. For example, you might create a Smart Mailbox that displays all messages found in all mailboxes from a specific sender.
If you change a message in a Smart Mailbox, such as marking the message as read or unread, or moving or deleting the message, the change is reflected in the mailbox where the message is actually stored.
So, adam, I would think that, if you had mail going to a lot of different places, and wanted to be able to see a particular set of those in a single place, you would use a smart mailbox. Maybe use the rules to direct your mail to different places to start with, but a smart mailbox to bring a set of common ones all together into a single smart mailbox?
Maybe you have Rules move your Amazon mail to an Amazon folder and your Apple mail to an Apple folder, but then you have a Smart Mailbox that contains any mail that has the word "Receipt" in the Subject line?
Just a thought....
Cheers,
GB
