Session Timezone differences between JDBC OCI and Thin drivers

Hi,
I was having a problem with a default on a DATE column of CURRENT_DATE with my Websphere/Oracle web application, when I discovered that the Thin JDBC driver behaves differently from the OCI JDBC driver in regards to the session timezone.
The Thin driver defaults the sesssion timezone to GMT (+0.00), but the OCI driver defaults to whatever the local OS timezone is (in my case GMT+12.00).
Can anyone tell me how why this difference is there how to correct the behaviour of the Thin driver?
I'm using the standard JDBC Connection class, not the OracleConnection object, and therefore cannot use the setSessionTimeZone method.
The only solution I can currently think of is to move the application over to the OCI driver, however, I'm wondering what else is different (ie we'll have to regression test the whole web app again!).
Any ideas?
Cheers,
Dunc

Well, regarding the time zone thing, it appears the following code will solve a lot of headaches...
((OracleConnection)conn).setSessionTimeZone
(TimeZone.getDefault().getID());
Still unknown why the OCI driver appears to do this automatically, while the thin driver does not.
If anyone knows the status of the memory leaks in the Linux OCI, please let me know.
Thanks,

Differences between jdbc connection and datasource connection

Hi all
What are the differences between javax.sql.datasource and java.sql.connection.
Is the datasource needed on in distributed databases or ??
In a distributed EJB enviornment, what happens if a component has a transctionattribute setting as SUPPORTS and tries to commit data - will the ejb container start a transaction though the setting is SUPPORTS.
Thanks in advance.

Hi all
What are the differences between javax.sql.datasource
and java.sql.connection.
Both are database connections. A connection is a handle to database. When you are directly creating a connection by calling Drivermanager.getConnection(..) , you are creating a connection by yourself and when closing close() on it, the link to database is lost. On the other hand when you get a connection from a datasource, when you call the close() on it, it will not close the link to database, but will return to a connection pool where it can be reused by some other classes. It is always better to use a connection pool because creating connections are expensive

You can create datasource to any databse local or remote.

hmmm..i am not sure. I think the container sets the commit and rollback points for it . so container will override database settings.

Whts the difference between call transaction and session

hi,
can u plz tell me the differnces between call transaction method in BDC and session method.
my doubt is even the call transaction method also can me scheduled using job scheduler then why do we need session method

Hi
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.

What's the difference between the LRU and NRU strategy for stateful session bean?

Hi,
Does anybody know the difference between the LRU and NRU strategy for
stateful session bean?
Thanks,
Levi

LRU makes the assumption that the bean that has been used a lot recently is
likely to be used again.
NRU simply removes the beans that have not been used for a stipulated amount
of time.
The algorithm for the LRU is much more complicated than the NRU. I think BEA
recommends LRU for better performance and NRU when you have memory
constraints.

Difference between maximum concurrency and batch mode in JDBC

Hi All,
Could som one tell me the difference between maximum concurrency and batch mode in receiver JDBC adapter?
Regards,
XIer

Hi,
The Max Concurrancy and Batch mode are used for performance tunning for JDBC adapter.
Max Concurrancy is possible upto 5 only. so even if you will be taking up 10 it will by-default take 5.
The number of records being processed depend on the size of each record. for e.g Per minit XI Is Processing 50 Records,It will Take lot of time to process all Records.
So if you set Max concurrancy as 5 then at time 5 messages will be processed simultaneously.
In Batch mode it will, collect the multiple SQL statements that will be created for records to be processed and processed at a time. It will improve performance considerably.
But Batch Mode is possible with only INSERT, UPDATE, DELETE etc.
The Stored procedures can be executed with max concurrency
Thus it completely depends that on the no of records to be processed at a time and volume of Mesasges.
Thanks

Is there a difference between Statement Cache and the statement handle!

Hello!
The OCI statement cache is !session! wide. When I have a sql statement that was used before, I can use this feature.
But what is the difference between this feature and my statement handle for a certain sql statement that I can store and reuse a second time?
My stored statement handle is already prepared and the placeholders are bound. The second time I only have to copy new values in the memory positions and do an execute and that's all.
Thank you in advance
Wolfgang

The underlying optimization is the same. When you re-execute a statement, you are reusing the metadata already available in the statement and the cursor already open on the server. If you know exactly the set of statements that you are going to execute repeatedly, you can maintain the cache on your own. (Yes, you save on doing the Bind/Define calls multiple times).
OCI Statement cache makes it transparent and the application does not need to keep the references/indexes to the relevant statements. Also once a cache size is set, least recently used statements get out of the cache when the cache is full and needs to accommodate more.
To optimize the bind/defines on the statements from the statement cache, you can use this feature:

Difference between connection pooling and simple connection

Anybody please tell me what is the Difference between connection pooling and simple connection and also where we define connection pooling and how.
Thanks
Please reply soon
amitindia

Creating and closing connection to the database is a relatively slow process. Equally connections use database resources so you can't just open as many as you want.
A connection pool maintains a number of open connections throughout the lifetime of the application. Instead of opening and closing the connections your application just "borrows" them from the pool when they're needed.
If the pool runs out of connections it will usually create new ones as needed until you reach some predefined upper limit.
A good connection pool will also manage connections which have failed for any reason, and report code which fails to return connections to the pool (ie connection leaks).
The number of connections created at startup is referred to as the "low water mark" and the maximum number that the pool will allow to be opened at any given time is the "high water mark". If no connections are available client code will generally block until one is released.
If by "defined" you mean where can you get a working implementation then your database or application server vendor is likely to provide one. Also the Apache Jakarta Commons includes [url http://jakarta.apache.org/commons/dbcp/]an implementation which you can use with any JDBC driver.

Differences between oracle 10gr2 and 11gr2 warehouse bulider

Hi All,
Could you please let me know the main differences between Oracle 10gr2 and Oracle 11gR2 warehouse builder.
Also , it would be great if anyone point me to the document where i can see the major differences.
Thanks,
Naveen.

Hi Naveen,
The major difference between OWB10gR2 and 11gR2 is the target RDBMS.
In 10gR2 you have to use ORACLE as your target RDBMS (unless you are going for DB Gateways, that is a complete different story).
Where as in 11gR2 allows you to use any RDBMS as your target system . This is achieved by Code-Template mapping.
All is needed is that proper jdbc driver for the target system.
Also 11gR2 supports OBIEE RPD creation and etc.

Question about main difference between Java bean and Java class in JSP

Hi All,
I am new to Java Bean and wonder what is the main difference to use a Bean or an Object in the jsp. I have search on the forum and find some post also asking the question but still answer my doubt. Indeed, what is the real advantage of using bean in jsp.
Let me give an example to illustrate my question:
<code>
<%@ page errorPage="errorpage.jsp" %>
<%@ page import="ShoppingCart" %>

<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
<html>
<head><title>Shopping Cart</title></head>
<body bgcolor="#FFFFFF">
Your cart's ID is: <%=cart.getId()%>.
</body>
<html>
</code>
In the above code, I can also create a object of ShoppingCart by new operator then get the id at the following way.
<code>
<%
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
%>
</code>
Now my question is what is the difference between the two method? As in my mind, a normal class can also have it setter and getter methods for its properties. But someone may say that, there is a scope="session", which can be declared in an normal object. It may be a point but it can be easily solved but putting the object in session by "session.setAttribute("cart", cart)".
I have been searching on this issue on the internet for a long time and most of them just say someting like "persistance of state", "bean follow some conventions of naming", "bean must implement ser" and so on. All of above can be solved by other means, for example, a normal class can also follow the convention. I am really get confused with it, and really want to know what is the main point(s) of using the java bean.
Any help will be highly apprecaited. Thanks!!!
Best Regards,
Alex

Hi All,
I am new to Java Bean and wonder what is the main
difference to use a Bean or an Object in the jsp. The first thing to realize is that JavaBeans are just Plain Old Java Objects (POJOs) that follow a specific set of semantics (get/set methods, etc...). So what is the difference between a Bean and an Object? Nothing.
<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
In the above code, I can also create a object of
ShoppingCart by new operator then get the id at the
following way.
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
...Sure you could. And if the Cart was in a package (it has to be) you also need to put an import statement in. Oh, and to make sure the object is accessable in the same scope, you have to put it into the PageContext scope. And to totally equal, you first check to see if that object already exists in scope. So to get the equivalant of this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart"/>Then your scriptlet looks like this:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = pageContext.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    pageContext.setAttribute("cart", cart);
%>So it is a lot more work.
As in my mind, a normal class can also
have it setter and getter methods for its properties.True ... See below.
But someone may say that, there is a scope="session",
which can be declared in an normal object.As long as the object is serializeable, yes.
It may be
a point but it can be easily solved but putting the
object in session by "session.setAttribute("cart",
cart)".Possible, but if the object isn't serializable it can be unsafe. As the point I mentioned above, the useBean tag allows you to check if the bean exists already, and use that, or make a new one if it does not yet exist in one line. A lot easier than the code you need to use otherwise.
I have been searching on this issue on the internet
for a long time and most of them just say someting
like "persistance of state", "bean follow some
conventions of naming", "bean must implement ser" and
so on. Right, that would go along the lines of the definition of what a JavaBean is.
All of above can be solved by other means, for
example, a normal class can also follow the
convention. And if it does - then it is a JavaBean! A JavaBean is any Object whose class definition would include all of the following:
1) A public, no-argument constructor
2) Implements Serializeable
3) Properties are revealed through public mutator methods (void return type, start with 'set' have a single Object parameter list) and public accessor methods (Object return type, void parameter list, begin with 'get').
4) Contain any necessary event handling methods. Depending on the purpose of the bean, you may include event handlers for when the properties change.
I am really get confused with it, and
really want to know what is the main point(s) of
using the java bean.JavaBeans are normal objects that follow these conventions. Because they do, then you can access them through simplified means. For example, One way of having an object in session that contains data I want to print our might be:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    session.setAttribute("cart", cart);
%>Then later where I want to print a total:
<% out.print(cart.getTotal() %>Or, if the cart is a JavaBean I could do this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session"/>
Then later on:
<jsp:getProperty name="cart" property="total"/>
Or perhaps I want to set some properties on the object that I get off of the URL's parameter group. I could do this:
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    cart.setCreditCard(request.getParameter("creditCard"));
    cart.setFirstName(request.getParameter("firstName"));
    cart.setLastName(request.getParameter("lastName"));
    cart.setBillingAddress1(request.getParameter("billingAddress1"));
    cart.setBillingAddress2(request.getParameter("billingAddress2"));
    cart.setZipCode(request.getParameter("zipCode"));
    cart.setRegion(request.getParameter("region"));
    cart.setCountry(request.getParameter("country"));
    pageContext.setAttribute("cart", cart);
    session.setAttribute("cart", cart);
}Or you could use:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session">
<jsp:setProperty name="cart" property="*"/>
</jsp:useBean>The second seems easier to me.
It also allows you to use your objects in more varied cases - for example, JSTL (the standard tag libraries) and EL (expression language) only work with JavaBeans (objects that follow the JavaBeans conventions) because they expect objects to have the no-arg constuctor, and properties accessed/changed via getXXX and setXXX methods.

Hi Friends ....Difference between SAP memory and ABAP memory

Hi Friends,
I faced a interview and they ask this question
What is the difference between SAP Memory and ABAP memory..

conti
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens.
ABAP Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
A simple example of ABAP memory is using the EXPORT/IMPORT statements.
Here in this program, I get the data, export it to memory,
clear out the internal table in my progam, then reimport the data into it and write out the data.
You probably wounldn't do this in a normal program,
but this is how you can pass data from program a to program b when A Submits program B.
report zxy_0002 .
data: it001 type table of t001 with header line.
select * into table it001 from t001.
export it001 = it001 to memory id 'ZXY_TEST'.
clear it001. refresh it001.
import it001 = it001 from memory id 'ZXY_TEST'.
loop at it001.
write:/ it001-bukrs, it001-butxt.
endloop.
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access.
You can use SAP memory either to pass data from one program to another within a session,
or to pass data from one session to another.
Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters).
These parameters can be set either for a particular user
or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement.
The most frequent use of SPA/GPA parameters is to fill input fields on screens
ABAP/4 Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access
using the EXPORT and IMPORT statements.
Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling,
the data needs to be placed in ABAP memory before the call is made.
The internal session of the called program then replaces that of the calling program.
The program called can then read from the ABAP memory.
If control is then returned to the program which made the initial call, the same process operates in reverse.
SAP memory
The SAP memory, otherwise known as the global memory,
is available to a user during the entire duration of a terminal session.
Its contents are retained across transaction boundaries as well as external and internal sessions.
The SET PARAMETER and GET PARAMETER statements allow you to write to, or read from, the SAP memory.
ABAP/4 memory
The contents of the ABAP/4 memory are retained only during the lifetime of an external session
(see also Organization of Modularization Units).
You can retain or pass data across internal sessions.
The EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow you to write data to, or read data from, the ABAP memory.

Difference between DB CPU and DB Time

Hi,
What is the difference between DB CPU and DB TIME in AWR report?
Br,
Raj

Hi,
Thanks for your valuable reply.
1,DB CPU is time spent on CPU. It means only ACTIVELY working on CPU. WAIT TIME is not includeed.
In 10 Minute interval with four CPU, Is the Maximum DB CPU 40 Minutes?
2,I read the below document about DB time. http://www.perfvision.com/docs/JB_AAS.pdf
I unable to understand at page 6.
It says that DB Time = Includes CPU Time + IO Time + Wait Time
I understand about Wait time.
CPU also involved to do I/O Time? Is it RIGHT?.Hence, Why did seperate CPU Time and I/O time in the document?What is the purpose of it?
Is it possbile to further divided the CPU TIME ? Like parse etc.....Which view provide it?
3,If you had four sessions actively working or actively waiting 100% of the time in that 10 minute period, then your DB time would be 40 minutes.
In a given interval,Where can i find NON Idle wait time in AWR?
Plese help me out it
Br,
Raj

a user is a schema and schema is a user. but when this applies to the user that he become a schema, only if he has got some objects. so we can say while creating the user which dosent contain any objects called simple user account but afterwords when he has got an objects then we can say its a schema as the above user has shown you through the exampleIt is just word-play. There is nothing in like a 'status' indicator to say "USER_A is just a user but USER_B has become a schema". Many people use the terms "user" and "schema" interchangeably, and some very good DBAs will insist this is correct. I don't disagree with them even though I usually try to make the distinction.
In a typical application, all of the objects (tables, procedures, etc) that implement the app will be owned by a "application schema owner" - a user which exists for the sole purpose of owning the schema. Said user will have no privileges at all .. especially not CREATE SESSION. Except for possible maintenance activity no one ever actually connects as this user. User accounts are then given to actual humans who connect with their own accounts. The accounts have the necessary system and object privileges granted to them - via a role. One could also create a special account (let's call it APP_ADMIN) that is used for maintenance and batch operations within the application.
