can any one provide all the necessary information for linking 2 different oracle databases and retriving data for jsp web application.
In one of my new web application i need to retrive data from 2 different oracle database's and show a report.
At present ,the application is using linked tables for Ms-Access.
I need to migrate the application from Access,StandAlone application to Oracle,Web application .

Oracle database administrators tend to be control freaks, especially in financial institutions where security is paramount.
In general, they will supply you with a database, but require you to supply all the DDL scripts to create tables, indexes, views etc.
So a certain amount of manual installation will always be required.
Typically you would supply the SQL scripts, and a detailled installation document too.

How to create a oracle database by java code?

how to create a oracle database by java code?
please give some ways then that way's code

I'm not sure what you mean with "database". Do you mean an Oracle instance or an Oracle user/schema (probably the latter, because that's the equivalent to a MS SQL Database).
Creating an instance is definitely not possible from within Java. To create a new user this should be possible, as this can be done with SQL:
GRANT connect,resource TO <newuser> IDENTIFIED BY <password>;
I'm always cautious with questions like this. In 90% of the cases there is something wrong with the initial design. Creating a database shouldn't be something the application is doing.

How to connect Oracle database through Microsoft ODBC?

My ODBC Configuration:
DSN name is :db
Username : india
Server :db.world
Now, i am trying to connect with oracle database through SQL*plus or TOAD.
But, it is giving the following error.
ORA-03121: no interface driver connected - function not performed
Database version : 9.2.0.1.0
Operating System : Microsoft Windows XP
ODBC Version : 2.575.1117.00
I am trying to connect with the database like this:
Username : india
Password : india
Database : ODBC:db
Can i connect like this otherwise whether i need install any other supporting driver?

Now, i am trying to connect with oracle database
through SQL*plus or TOAD.
But, it is giving the following error.
ORA-03121: no interface driver connected -
function not performed
I am trying to connect with the database like this:
Username : india
Password : india
Database : ODBC:db
As already stated, you can not use the DSN in SQL*Plus (nor TOAD, afaik)!
I can reproduce the error message with the following:
C:\>sqlplus a/b@ODBC:c
SQL*Plus: Release 11.1.0.6.0 - Production on Mon Aug 4 21:34:58 2008
Copyright (c) 1982, 2007, Oracle. All rights reserved.
ERROR:
ORA-03121: no interface driver connected - function not performedLooking up the message, it says:
Cause: A SQL*Net version 1 prefix was erroneously used in the connect string
Looks like this has nothing to do with your DSN - it is more a matter of not using a proper connection string.
If 'Test Connection' works then you should probably proceed to work with Crystal Reports, using the DSN in question.
However, you should note that the old MS ODBC driver for Oracle was designed for OCI 7 (and for databases 7.x-8.x) and is now considered obsolete by both MS and Oracle.
Deprecated MDAC components and MS KB Article 244661.
Use the Oracle ODBC driver included with a supported Client version instead.
Edit:
Clarifying and adding references.

How to connect oracle database with JAVA

how to connect oracle database with JAVA....
using j2sdk and Jcreator . which connector to use .. what are the code for that ..

PLEASE .... Ask in an Oracle Java forum.
And read the documentaiton. There is a whole document devoted to doing that. http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/toc.htm has examples.
PLEASE ... do not ask product questions in a forum which clearly has a title saying it is devoted to assisting with download problems.

Java App connection to an Oracle Database through Oracle Stored Procedure

My team's access to its Databases (Oracle only) is restricted to access through Oracle Stored Procedures that are part of the Oracle Database. So, in my Java App I need to call the Stored Procedure that will give me the access to the table that I need, declare the right parameters and execute the command. The Stored Procedure will then hand me the data I need.
I am finding support on the web for creating Stored Procedures in Java, but that is not what I need.
Can anyone post here a class that addresses this, or point me to a link that will shed some light on it?
Thanks

I am looking for Java code that will do what this .NET code below does (connects to a database and writes data to the table through an Oracle stored procedure that is part of the Oracle Database.)
So learn Java, learn JDBC and translate the requirements; don't attempt to translate the code as the platforms are too different.
From a quick glance it looks like a JDBC CallableStatement can do the job.

Sending Long Raw Data to Oracle database through Stored Procedure

Hi,
I am trying to push data to Oracle 9i database through Stored Procedure via thin driver. It is going smoothly upto 29411 bytes. But it is not accepting for 53843 bytes and giving following error :
java.sql.SQLException: Data size bigger than max size for this type: 53843
Is it thin driver limitation? Can I solve it by using OCI driver? Or is there any other approach?
I tried creating connection pool in weblogic 7.0 through OCI driver. But I am not able to configure it. Is there any special way of configuration.
Quick response will be greatly appreciated.
Thanks

It happens to me. But I am using CMP of Weblogic 7. If you write your own jdbc code, the following link may be helpful.

Retrieve data from a synonym in oracle database through db connect

Hi Everyone,
I have created certain synonym for some tables in oracle. I want to retrieve data from it through db connect but where through source system and then selecting database tables, only tables and views are available.
Synonyms are not available to create data sources and retrieve the data from it. Why is it so. Is this a limitation of db connect.
Can anyone please let me know about it.
Thanks,
Joshua.

Hi,
You want to import data from an external Oracle database into your BW 3.X. To do this, you can connect the external database to the BW 3.X release as a source system using the external database connect. BW 3.X here represents BW 3.0, BW 3.1 and BW 3.5 because in other (DB relevant) parts, all 3 versions are based on the same source code.
General information
The above function allows you to load data from an external Oracle database (not a BW database) into your BW 3.0 system.
There may also be constellations which cannot be used directly through the DB Connect access. However, it should be possible to find an adequate, customer-specific solution for most of these scenarios.
In such situations, the resulting work falls into the area of Consulting and cannot be handled via Support.
Successful implementation of a connection requires corresponding expertise and experience in the use of the source database in the areas:
                - Tools
                - SQL syntax
                - DB-specific functions
Corresponding knowledge of the source application is also required to ensure that semantically relevant data arrives in the BW system.
Procedure
You should execute the following steps to connect the source system (Q) to the BW system (BW):
Installing the client software on an BW application server
                     Of course, you only need to install the client software if you are using BW with a non-Oracle database.
                     Use the Oracle setup program on the database CD (runInstaller on Unix) to start the OracleInstaller. Follow the program instructions and the DB installation instructions to install the Oracle Client software on BW.
Testing connection setup from BW to Q
                     After you install the client software on BW, try to set up a connection from BW to the server on Q. You may need to adjust the tnsnames.ora or sqlnet.ora files for this, to introduce the Oracle systems (to which contact should be made) to BW. You can test the connection by executing the command "tnsping QDB" on BW to check whether the client has established contact to the QDB database on the Q system.
Creating a separate U user in Q
                     We recommend that you create a separate U user in Q for connection to BW. This means that authorization and administration questions can be solved centrally.
Displaying data sources in Q for the U user
                     To provide U data for users other than U, you can create views on other user tables as user U:
                     CREATE OR REPLACE VIEW viewname AS
                       SELECT * FROM QDB.tablename
                     You may have to grant SELECT privileges to user U in the QDB schema:
                        GRANT select ON QDB.tablename TO U
                     Of course, you can also restrict or reformat data in the view arrangement (for example, change from internal date format into the SAP date format). JOIN operations using several tables are also available.
                     !!! Synonyms do not yet work!!!
                     Synonyms that you can create as described below are another option for providing a complete table for the user U:
                       CREATE SYNONYM synoname FOR QDB.tablename
                     !!! Synonyms do not (yet) work!!!
                     After you have displayed the require data for user U, you can simply use
                       SELECT * FROM <view or table>
                     on the Q system to check which data is returned.
                     You can now open a link to Q as user U in the BW system with SQLPLUS and check, using the same SELECT, whether this data is also seen in the Oracle client. If this is not the case, there is probably a connection problem.
Creating a connection from BW to Q in BW
Including data sources of user U user in Q in BW.
Solution
Supported BW, Basis and BW 3.0B database versions, Basis 6.20 Support Package 2 (or higher)
      Oracle 8.1 (or higher, see below)
Possible problems
- Synonyms do not (yet) work!
Up to now, only tables and views have been used as data sources for the DB Connect from the R3 Basis. As soon as synonyms are also used in the Basis, you will be able to convert created views (or even replicated tables) to synonyms as a workaround.
With Basis 6.40 at the earliest, therefore as of BW 3.5, you will also be able to use synonyms. Until then, the following will help:
CREATE VIEW <view_on_synonym> AS SELECT * FROM <synonym>
- The source DB must have at least the release version of the BW DB.
Oracle only ensures the support of client-server links if the version of the client is not higher than that of the server. So if BW has Oracle version 8.1 and, as in the case of Dbconnect, is run as a client against the server of the source database, the source database must have at least release Oracle 8.1 or higher.
Of course, you have the option to install the Oracle client software of a lower version and then use this for the DB connect. This is also the procedure used to work with a DB connect on external databases of other vendors.
Furthermore, the implementation of the DBconnect function in BW uses SAP Basis functions. Specifications of Oracle 8.1 database catalogs are used here. The source database must therefore have at least Version 8.1.
- Oracle Client Software Version
If you want to connect from an Oracle BW DB to an Oracle source DB, for the DB connect you naturally use the client software that you already installed on each application server.
If you want to connect from a non-Oracle BW DB to an Oracle source DB, check item 3 of note 521230 to see which Oracle client software version is released with your BW R3 kernel and use this version.
- Date and time fields in Oracle and their conversion into SAP-compatible column formats
Example with a DATE field:
Since a SAP table does not have a DATE field (date values are NUMC(8) and time specifications are NUMC(6)), we will use the Oracle DBA_TABLES system table as an example.
    SQL> desc dba_tables;
The Oracle DBA_TABLES system table has a LAST_ANALYZED field. This is a DATE type field and is recognized as a date field of 7 characters by DBA_CONNECT. However, the import does not work because the DATE is a 7-byte conglomerate of "...century, year, month, date, hour, minute and second." (extract from the Oracle documentation).
To make this DATE field legible for DB connect, you must use the TO_CHAR function in a VIEW. This should display the following examples:
SQL> select LAST_ANALYZED from dba_tables
      where table_name like 'RS%' and rownum < 10 ;
The formatting used here is the default used implicitly by SQLPLUS.
SQL> select to_char(LAST_ANALYZED,'YYYYMMDD') as dat from dba_tables where table_name like 'RS%' and rownum < 10 ;
The result now has the SAP compatible format YYYYMMDD and should be loaded correctly by the DB connect as a date.
SQL> select to_char(LAST_ANALYZED,'HH24MISS') as tim from dba_tables where table_name like 'RS%' and rownum < 10 ;
The result now has the SAP compatible format HHMMSS and should be loaded correctly by the DB connect as a time.
You can use the following example for more detailed experiments:
SQL> select to_char(
       TO_DATE('03-FEB-2001 04:05:06','DD-MON-YYYY HH24:MI:SS'),
       'YY-MM-DD HH24-MI-SS') as datim from dual;
with the result:
DATIM
01-02-03 04-05-06
When you create a VIEW and use the TO_CHAR function (or other functions), you should easily be able to avoid problems with the interpretation of date/time specifications (and other reformatting).
Details about the functions and the formats are contained in the Oracle documentation.
- Special characters
A words that contain special characters can only be imported correctly if the code pages in BW and in the source system are identical. If the code pages are not the same, DB Connect can be used if the characters to be imported appear under the first 127 characters of the character set.
The use of multibyte code pages in the source system for saving data using character sets with more than 256 characters (Kanji, Katakana, Hiragana, Korean, Chinese, Tagalog, Khmer, Arabic, Cherokee, and so on) can cause the characters to become corrupt.
For questions concerning the code pages, also refer to the FAQ note 606359 and question/answer 19 that appears there.

We were able to do the same thing with Oracle Application Server and Oracle WebLogic Server. I cannot remember how different the processes were, but it seems like they were very similar. I am going to give you the instructions on how we implemented a "Read PDF" procedure on the WebLogic Server. If you are still on the Application Server you may have to do some Google searches, but it all boils down to the mod_plsql DAD Configuration file.
Our PDF was located in a table with the following structure:
CASE_DOCUMENTS
   (id_document                    NUMBER NOT NULL,
    doc_blob                       BLOB,
    note                           VARCHAR2(240),
    created_by                     VARCHAR2(20) NOT NULL,

    filename                       VARCHAR2(100) NOT NULL)Based on that table structure we created a procedure named READ_PDF which you will reference below in the dads.conf file below:
CREATE or REPLACE procedure read_pdf (p_id_document IN number)
is
view_file     blob;
BEGIN
select doc_blob
    into view_file
    from case_documents
   where id_document = p_id_document;
OWA_UTIL.MIME_HEADER ('APPLICATION/PDF', FALSE);
HTP.P ('CONTENT-LENGTH: ' || DBMS_LOB.GETLENGTH (view_file));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (view_file);
END;
GRANT EXECUTE ON read_pdf TO financial_user_role -- Name of role to execute
/Basically, you are passing in one parameter and that is the primary key for your table. You are selecting the pdf stored in a BLOB for that primary key. The commands below that allow the pdf to open up so you can view it – we got this off some search we did a few years ago.
Now, you need to add logic to your Oracle Form that will call the procedure above, but the URL is based on the dads.conf file that we will set up below… Anyway, we created a button on the form module with a label of "View". In the WHEN-BUTTON-PRESSED trigger the logic looks like this:
-- The View logic uses the DAD (Database Access Descriptors) method to view a .pdf file from the form.
-- The DAD was created on WebLogic Server with the name findadgen. This allows an http request be made
-- to the database.
declare
v_file          varchar2(400);
v_success       boolean;
ret_val         number;
v_http_link     varchar2(400);
begin
-- The format of the link is as follows: hostname:port/pls/DAD_name/procedure_name
v_http_link := 'http://finas03:8888/pls/findadgen/read_pdf?p_id_document=' || :case_documents.id_document;
web.show_document(v_http_link, '_BLANK');
end;The name of our WebLogic Server is "finas03" so that is what is listed in the URL. The "findadgen" is the name of the <Location> in the dads.conf file below, the "read_pdf" is the name of the procedure we created above, the "p_id_document=" is the IN parameter listed in the READ_PDF procedure created above, and the ":case_documents.id_document" is the reference to the primary key in our Oracle Form.
For WebLogic, you can either go through Enterprise Manager (directions below) or update the dads.conf file on the filesystem directly (if you update the dads.conf file directly then skip to step 4 and ignore step 5):
1.     Enterprise Manager -> Web Tier -> ohs1
2.     Oracle HTTP Server (pull-down) – Administration – Advance Configuration
3.     Select File – dads.conf
4.     Add something similar:
# ============================================================================
#                     mod_plsql DAD Configuration File
# ============================================================================
# 1. Please refer to dads.README for a description of this file
# ============================================================================
# Note: This file should typically be included in your plsql.conf file with
# the "include" directive.
# Hint: You can look at some sample DADs in the dads.README file
# ============================================================================
<Location /pls/findadgen>
    SetHandler pls_handler
    Order allow,deny
    Allow from All
    AllowOverride None
    PlsqlDatabaseUsername financial
    PlsqlDatabasePassword sdo_3#d1
    PlsqlDatabaseConnectString ffindbTNSFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8ISO8859P1
    PlsqlAuthenticationMode Basic
    PlsqlDefaultPage read_pdf
</Location>You are adding the <Location> section to your dads.conf file. The "finddadgen" is the name that you will reference in a change you fill make to your Oracle Form. The "financial" is the Schema, the "sdo_3#d1" is the password for that Schema, the "ffindb" is the database that the stored procedure is located on, and the "read_pdf" is a stored procedure you will have to create in order to read the pdf.
5.     Press the "Apply" Button
6.     Obfuscate the DAD password by running the dadTool.pl script located in $ORACLE_HOME/bin (This was done on Unix on our server with the following commands):
$> LD_LIBRARY_PATH=$ORACLE_HOME/lib;export LD_LIBRARY_PATH
$> cd $ORACLE_HOME/bin
$> perl dadTool.pl -f /u01/app/oracle/middleware/asinst_1/config/OHS/ohs1/mod_plsql/dads.conf
7.     Restart the Oracle HTTP Server using Fusion Middleware Control:
Enterprise Manager -> Web Tier -> ohs1
Oracle HTTP Server – Control – Shutdown
Oracle HTTP Server – Control – Start Up
If you followed the instructions above, you should have created a stored procedure, added logic to your Oracle form to reference that stored procedure, and created an entry in the dads.conf file. Once you move the form onto the server and you restart the HTTP Service, you should be able to view a pdf that is stored in a table directly from your Oracle Form.

Go to System Administration
-> System Configuration
-> System Landscape
-> select a Folder where you want to store your system object
-> right click -> New System
-> in the wizard, select JDBC System
-> enter values
-> edit
Then fill in the correct values as stated here:
http://help.sap.com/saphelp_nw04/helpdata/en/84/d5df3df2ad685ae10000000a11405a/frameset.htm
Then assign an Alias and enter some usermapping data for the system.
You then can use the ConnectorService to get a native sql connection and fire statements. I'm sure you can find some examples here.

Connecting Oracle DataBase through WebDynpro

Hi,
I created a Dynamic table, now I should display the data from Oracle Database. I tried in many various ways to connect to database, but the data is not retrieving.
Can u explain the reasons and give necessary coding to retrieve the data.
Its very very urgent.

Hi
I think you can do using the APIs provided by SAP.
Check this link
JDBC Reference
or
Try connectinc using lookup.
try{
InitialContext ctx=new InitialContext();
javax.sql.DataSource ds=(javax.sql.DataSource)ctx.lookup("jdbc/SAPJ2EDB");
java.sql.Connection con=ds.getConnection();
java.sql.Statement stmt=con.createStatement();
con.close();
catch(Exception e)
wdComponentAPI.getMessageManager().reportException("Exception "+e,true);
Check this thread moreuseful.
