Who understand the concept of EBS USER and LINUX USER

When we login the EBS, we will use a user(user1), and then we create a file to the server.
When we use TELNET to login the server, we can see the file is created by another user(user2).
How to understand both two users, and how to be relationship between those?
Thanks.

When we login the EBS, we will use a user(user1), and then we create a file to the server.What is the application release? OS?
When we use TELNET to login the server, we can see the file is created by another user(user2).What is the file? What kind of file system you have? Please post the steps you follow to explain your question.
How to understand both two users, and how to be relationship between those?If the file was created by one user, the ownership of the file will belong to the same user who created the file. If you see a different behavior, please show the case by listing the steps -- (i.e. post the commands of --> login to the server as user1, create a file as user1, show the id of the user and use the ls command to show the ownership, then login to the server as user2 and issue the same ls command).

Unable to understand the concept of Primary Key in EJB

hi,
please help me in understanding the concept of Primary Key.
For each and every entity bean represents a data base row. i think it is correct. if multiple users are accessing the same data base row, there will be different primary key for each and every client. is it correct or not. can we say this as "concurrency"?. if all the clients are manipulating the bean, who manages it either application server or data base server?. why does we must implement both hashCode() and equals() methods?. Provide me the links where i can find the answers.

if multiple users are
accessing the same data base row, there will be
different primary key for each and every client.This is incorrect: the PrimaryKey is the unique identifier for each database row. It has nothing to do with users. In order for CMP to work, the container must be able to operate with a single row in the database and be able to distinquish between them.
If your CMP->database table already has one column that's unique, then you declare that CMP field to be <primary-key-field>. If you have more than one column that makes a row unique, you must make your own primary key object. The way the container can tell the difference between these primary key objects is to compare them, therefore the hashCode and equals methods.
Provide me the links where i can find the
answers.This is all discusssed in the J2EE Tutorial.

EHP Upgrade - Trying to understand the concept

Dear experts, this is an effort to understand the concept. I have been doing Basis work for the past 10 years approximately. All along, I have been doing the typical LCP and SP upgrades way back from legacy systems until now (ECC 5.0 / BW 3.5). We have recently upgraded our BW 3.5 to BI 7.01 and also created a dual stack (we never had Java stack before for BW). This is my situation. Below are my questions. Any guidance would be highly appreciated.
1. Do we still have the SP Stack upgrades within Ehp 1? Or, has it been revamped completely and there is no more SP upgrades and we only need to do EhP upgrades? In this case, if I have to upgrade from Netweaver 7.01, is my only option upgrading to 7.02?
2. Is there a place where I can start to catchup with the whole EhP concept? I would like to know the maintenance life cycle and the impact on our environment.
3. Are there any specific upgrade guides that will guide me in transitioning from the typical SP upgrade methodology to EhP upgrade methodology. Also, I would like to know how did you transition (learning curve) from someone who had been with typical SP upgrade for a long time and how did you adopt yourself to the new path (like what guides did you use, what links did you follow, etc)
NOTE: I have heard the EhP upgrades are similar to release upgrades and I have done handful of release upgrades.
Thank you so much in advance.

Yes we do have both option available. Either we can go for SP upgrade or we can go with EHP upgrade.

I'm trying to understand the difference between Photoshop Elements and Lightroom software.

Does one have things the other does not?

Hi,
Lightroom is to manage photos and produce derivative images without ever modifying an original file. Its processing functionality has a narrow feature-set covering the most common needs of professional photographers whereas Elements is a simpler yet powerful photo manipulation tool. Elements is designed to satisfy the needs of photo enthusiasts who like to manipulate images.
You can also go through the thread to understand the basic difference between PSE and Lightroom.
Check if this helps.
Thanks,

Anyone who has the src of JavaTM Look and Feel Design (second edition)?

Anyone who has the src of JavaTM Look and Feel Design (second edition)? It would be really appreciated to let me know.
Thanks -

My bad, my post was unclear.
I wasn't sure what you meant by src. You clarified that point.
By (re)reading parts of the online text book, I realized that it's quite outdated. They really should issue a more up-to-date version.

Help with understanding the Home Folder plus User Accounts

I just got the IMac (replacing an ageing...that is an understatement...Grape iMac from long ago) and this is my first go at the OSX. My previous iMac had OS9.2
I am having a problem understanding the Home folder and the Users to a point. The concepts are fine, it is the changing of names that is the problem. When I first started the iMac and went through the set-up and finally looked at the file structure, there was the Home Folder with a name, which i guess was pre-entered during set-up since I did not enter it (lets call it JOE). There was also 1 User, JOE with all the iLife folders. Since I did not like the name, i went to the Systems Preferences, into Accounts and found that JOE is an Admin. So, I changed the name to, lets say BILL, who still is an Admin. I also changed some settings and made BILL the auto log account. OK so far I am happy. I go back to the HD and find that now there are 2 users (folders), BILL and JOE, and that the Home Folder is still named JOE butall the iLife files are now under BILL.
So I went and also renamed the Home Folder to BILL, so everything looks fine. But when I restarted the iMac latter it lost all the settings (mouse, etc.) This is really getting confusing.
Here is what I want to do (after some reasearch):
I want to change the Short Name (JOE) but so far I have read that you can not do that. Where did this name come from (basically my first initial and my last name) because I don't want my Home Folder to be named that. I found somewhere that the only way to do that is an Erase and Install. I am willing to do that since I have a backup of all the iLife files on an external disk anyways and I have not put anything new yet.
Can someone enlighten me as to what would be the best course of action....this Short Name thing is frustrating.
iMac 20" 2.33MHz Mac OS X (10.4.9)

Welcome To Discussions kapklo!
First you need to sort out the extra Home folder issue, that was created by changing the Short Names.
The info in one or more of the articles linked to below, will help you with that.
Return to Default Desktop, Apparent "Loss" of Home Directory
My home folder and desktop are different than before
Recover from renaming your Home folder, authored by Dr Smoke
Then you can change the Short Name using this Change Short Name The Easy Way.
Or you could do an Erase & Install, making sure you enter your preferred Short Name, during the setup process.

Help needed in understanding the concept of hierarchical queries

I really need help in this matter. I have a flafile containing about 4000 rows. It is from my supplier, it's structure is as follows:
create table Flatfile
(Pgroup varchar2(30),
Pclass varchar2(30),
Manufacturer varchar2(30),
Article varchar2(30),
Price Number(6,2));
Insert into Flatfile Values
('Application Software','Database Software','Oracle','Oracle 10G',115);
Insert into Flatfile Values
('Application Software','Database Software','Microsoft','MS SQL Server 2000',200);
Insert into Flatfile Values
('Application Software','Spreadsheet Software','Microsoft','Excel',100);
Insert into Flatfile Values
('Monitor','15"','Acer','Acer 15"" TFT superscreen',199);
Insert into Flatfile Values
('Monitor','15"','Sony','Sony R1500 flat',225);
Insert into Flatfile Values
('Monitor','17"','Philips','Philips Flatscreen',250);
Insert into Flatfile Values
('Monitor','19"','Viewsonic','Viewsonic PLasma Monitor',275);
Insert into Flatfile Values
('Processor','AMD','AMD','FX-55',600);
Insert into Flatfile Values
('Processor','Intel','Intel','P4 3 GHZ',399);
My goal is to make a hierarchical query with the start with and connect by clauses. From what I have read is that I need to normalize the data of the flatfile.
How do I achieve a table which I can query so that the query will represent the hierarchy that exists. Namely
Pgroup
++Pclasse
Application Software
++Database Software
++Spreadsheet Software
So a 2-level hierarchy. I'd like to understand this simple concept first. I built on the knowledge that I gain. So the questions are:
1.What do I need to do to make the table so that I can use a hierarchical query on it?
2. How should the query syntax be?
3. Is it also possible to get the data in the hierarchical query sorted asec?
I would only like to use the simple structures of the start with and connect by clauses first. I've read there are some new additions to 10G. The problem with the examples used by the tutorials is that the tables are already made so that they are suitable for hierarchical queries. I hope to understand it by this example. And take it a step further.
Sincerely,
Pete

Primarily hierarchy query serves to process tree-like structures which RDBMS simulates using through parent-child relation, often in a single table (see famoust
EMP table where employee can have the manager who is an employee at the same time).
In your case it could look like:

As for the ordering question you can use siblings ordering:
SQL> select decode(level,1,pclass,' ' || pclass), Manufacturer from flatfile
2 start with pgroup is null
3 connect by prior pclass = pgroup
4 order siblings by 1 desc
5 /

I need help understanding the concept of Java...

Hello, this is my first post. I'm new to Java as well as programming, and I;m really having problems understanding the whole concept of classes, methods, arguments, parameters, constructors and so forth....can someone please explain this in baby terms....like a class is a big box and a method is something inside the box, or out!!!
thanks

Hi,
It looks you know nothing about programming. :)
Java is a very nice and easy programming language.
The best for you is to start programming to read a book
"Thinking in Java", Bruce Eckel. You can find it on the internet or download it from www.BruceEckel.com, or find it on www.filesearch.ru. This book will give you everything about Java. And then take any book what you like and go ahead. Practice, Practice and Practice!
Good luck!

The concept of http persistent and non-persistent

pls somebody explain me the concept of "keepalive type http".
when and where configure the persistent and non-persistent? not clear from the doc that HTTP-head, HTTP-get, classA and classB.
Thanks in advance.

Persistent will use HTTP version 1.1 while non-persistent will use version 1.0.
Use non-persistent only if your server does not support http version 1.1.
HTTP method HEAD or GET is selected with the command 'keepalive method'.
A head does not require the server to send us the content of the requested file, but simply an acknowledgement that the file is available.
The GET will request the complete file from the server and the CSS will verify that the content did not change compare to first GET request.
Again, I would recommend the default - head, unless you believe somebody could corrupt the content of your website.

Gilles.

Understanding the correct use of FromOrderComponets and ToOrderComponents

Hi all
Someone could help me understand the difference, and in what case I must use fromOrderComponets and in what case i must use toOrderComponents.
In the Decomposition Rules.
I've done multiple orchestrations to own cartridges, by multiple products, and I've never needed to use the expression toOrderComponents, because we've always used FromOrdercomponents.
any explanation is helpful,
Best Regards
David A Leon H

Hi Leon,
In the Design Studio Help, please refer to "Working with Decomposition Rules" inorder to understand Decomposition Rules.
Property Correlation is used while setting a dependency in the Product Specification. This is where FromOrderComponent & ToOrderComponent both are extensively used. For more information, please refer help section for the following.
1)About Order Item Dependencies
2)Orchestration Dependency Editor Order Item Dependencies Tab
