i want to connect a DataBase(oracle) through Tomcat5.
pls tell me the steps how can i do this .or pls give me any link
thanks previously

The bottom line is. If you can't figure this part out on your own then you have no business doing any JDBC programming anyway. Think of it as a minimal competency test to make sure it's safe for you to proceed. It isn't safe yet.

Ihave a problem to make connection to database Oracle when I use a simple code of java

[b]How can i connect with database(oracle 9i) from form developer at runtim

Hi Friends,
My problem is as follows, please show me a way.
Let's asume, I have form (developed in 6i) which has database data block. Now, at form level a have assigned on_logon trigger and I have written the following PL/SQL statement in that trigger:
begin
null;
end;
So, when I run this form without connecting to database It does not prompt for a connection. Now I have button lebeled as "Connect" in this form, when user will click on it it will display a window having text boxes to enter user name, password and database name; once the user fill those text boxes and click on a button lebeled as "Ok" then the form runtime environment should be connected with database as per information provided by user. Here to mention that the user already been created, only the connection will be stablished. For example: I want to connect the form with database as "scott/tiger@oradata9i".
To do this, what PL/SQL command statement should i write in that "OK" button's "when_button_pressed" trigger?
If any of you know about this please help me.

Hi
I've answered this question already. If I understand you right, you can use 'LOGON' built-in of Forms. Take a look into documentation.

It could be that the SID and SID_NAME is wrong.
Check SID=tg4ingr and SID_NAME=tg4ingr instead of SID=ingres

Log unsuccessful attemps connecting to database+Oracle error

Hi,
I've a simple trigger to log all user's unsuccessful attempts to connect to a database for the oracle error:ora-1017( invalid username/password when trying to login)
CREATE TABLE connection_audit (
login_date DATE,
username VARCHAR2(30));
-- trigger to trap unsuccessful logons
CREATE OR REPLACE TRIGGER T_LOGON_FAILURES
AFTER SERVERERROR
ON DATABASE
BEGIN
IF (IS_SERVERERROR(1017)) THEN
INSERT INTO connection_audit
(login_date, username)
VALUES
(SYSDATE, 'ORA-1017');
END IF;
END T_LOGON_FAILURES;
Now, I would've to log the unsuccessful attempts due to whatever Oracle error, along with the oracle error.
Can someone help me with the code changes?
Thanks,
Bhagat

I've created a trigger which inserts a record into table SERVERERROR_LOG for
every server error.
CREATE OR REPLACE TRIGGER T_LOG_SERVER_ERRORS
AFTER SERVERERROR ON DATABASE
** Purpose: T_LOG_SERVER_ERRORS TRIGGER -- THE SERVERERROR TRIGGER TAKES EVERY SERVER ERROR GENERATED
** FROM ORACLE PL/SQL AND PLACES IT INTO AN ORACLE TABLE.
** BY CAPTURING THE USER ID AND THE TIME OF THE ERROR, THE ORACLE ADMINISTRATOR WOULD BE
** IMMEDIATELY BE NOTIFIED VIA E-MAIL WHENEVER A SERVER ERROR OCCURS.
DECLARE
ls_user varchar2(30);
ls_osuser varchar2(30);
ls_machine varchar2(64);
ls_process varchar2(9);
ls_program varchar2(48);
BEGIN
SELECT username,osuser,machine,process,program
INTO ls_user,ls_osuser,ls_machine,ls_process,ls_program
FROM V$SESSION
WHERE audsid=userenv('sessionid');
INSERT INTO SERVERERROR_LOG
VALUES(
dbms_standard.server_error(1),
localtimestamp,
ls_user,
ls_osuser,
ls_machine,
ls_process,
ls_program);
END;
And My procedure below queries the table and notifies the Oracle Admin by
E-mail for every server error.(P_NOTIFY_SERVER_ERR is the procedure which does the job of sending mail to Admin).
PROCEDURE P_SERVER_ERRORS
AS
** Purpose: PROCEDURE FOR CHECK FOR SERVER ERRORS .
** INVOKE THE PROCEDURE P_NOTIFY_SERVER_ERR,WHICH NOTIFIES THE ORACLE ADMIN
** EVERYTIME SERVER ERROR OCCURS.
CURSOR C_SERVERERROR_LOG
IS
SELECT * FROM SERVERERROR_LOG;
BEGIN
FOR lc_servererror_log IN c_servererror_log
LOOP
P_NOTIFY_SERVER_ERR(lc_servererror_log.error,
lc_servererror_log.error_dt_time,
lc_servererror_log.username,
lc_servererror_log.osuser,
lc_servererror_log.machine,
lc_servererror_log.process,
lc_servererror_log.program);
END LOOP;
END P_SERVER_ERRORS;
An Oracle job executes procedure P_SERVER_ERRORS once every 5 minutes.
Thanks every one for your valuable suggestion.

1016: Could not connect to database - Oracle returned ORA-00257: archiver e

Dear buddies,
Receiving the above stated error.
Removed my old arch files to a different drive and now still getting the error.
How can I go about this.
Please advice.
Thanks!
Note: I am using Oracle 10g on a Windows platform
Edited by: user645399 on Jul 26, 2012 6:36 PM

After 1000+ posts you must understand that 10g is not a version number but a marketing label. This is what the error message says,
ORA-00257: archiver error. Connect internal only, until freed.
Cause: The archiver process received an error while trying to archive a redo log. If the problem is not resolved soon, the database will stop executing transactions. The most likely cause of this message is the destination device is out of space to store the redo log file.
Action: Check the archiver trace file for a detailed description of the problem. Also, verify that the device specified in the initialization parameter archive_log_dest is set up properly for archiving.If you have merely deleted the files using the o/s command, it won't update the Control File that those files are not available any more and the space mapped by them must be released. So you must use the RMAN's command crosscheck to confirm the deletion and mark the file's status as expired and then you would have to issue delete expired . Other than this, the only option would be to add more space to the destination where you are storing the archive logs.

How to connect access database through oracle sql prompt

i want to connect access database via oracle , i am trying to import all the data in Access table into oracle table how it is possible .
A.R

The simplest way, if You have already created tables in Oracle DB, is to open the Access MDB, link Oracle tables via ODBC and build a query to append rows reading from Access tables to Oracle tables.
Hope this helps

Hi Sushma
Ask your system Admin for servername,portnumber of database server
Connection conn=null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn =DriverManager.getConnection ("jdbc:oracle:thin:@<servername>:<portnumber>:DB","uname", "pwd");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from <tablename>"); // select statment
while(rs.next())
IXXElement nodeConnection=wdContext.createXXElement(); //creating a node to store the data from oracle
nodeConnection.setYY(rs.getInt("YY")); // setting the values into input fields
nodeConnection.setAA(rs.getInt("AA"));
nodeConnection.setBB(rs.getInt("BB"));
wdContext.nodeXX().addElement(nodeConnection); // adding the node
catch(Exception ex)
finally
try
conn.close(); // closing the connection

How to connect 10g database through Enterprise manager???

Hi All,
I want to connect the database through Enterprise manager.
My database is on 10g. Version is 10.1
Please tell me the procedure to connect the database through E.M.
Thanks and Regards,
Prathamesh.

Are you thinking of the Enterprise Manager supplied with Oracle9i? If yes - it doesn't work quite that way ... and the 9i java OEM is not compatible.
Use the enterprise manager supplied with the 10g database, called the dbconsole (look for a service or start it using 'emctl start dbconsole') and access it using http://{localhost}:5500/em
If that doesn't satisfy you, load the updated version of the OEM 9i java standalone from the 10g client disk.

No connection to an oracle database

Hello
I have installed database Rel. 2. JDevelopper 9.0.3.2 with BI Beans 9.0.3.6.
Additionally I installed the warehouse builder 9.2.0.2.8.
After I created a repository, a runtime repository and a target schema, I wanted to connect to my Oracle Database. But in the second window when you create a connector I can't choose a database. I can only mark unspecified...
Does anybody know why???
Damian

Yes I tried to use OWB.
I looked at OTN Documentation
(Oracle9i Warehouse Builder Installation and Configuration Guide)
So I installed OWB Design Time with the Installer, then I
installed the Design Repository using the Repository
Assistant. In addition I performed the OWB Server Side installation using Oracle Universal Installer. Then I installed a Runtime Repository, a Runtime Access User and a Warehouse Builder Target Schema.
After this installation I started the OWB Client and connected as Repository User. I received the make a ODBC Connection. But I want also make a connection to my local oracle database within a connector...
Now in this Printscreen (http://home.datacomm.ch/crettaz/printscreen.jpg) I can't choose my database. I have do configure more things?
