How to convert oracle 9i database to mysql using JSP?

Dear friends,
I want to convert oracle 9i database to mysql using JSP technology. Does there anyone who have a hint or some web links about this task? I searched the internet and found all of them are not free and no source code. In fact, what I want to do is really simple, I just want to first, reading the oracle database table structure information and then create the exactly same table in mysql, and then copying all the data in oracle database table to mysql table. But I don�t know how to retrieve the oracle table structure using JDBC. And also I want to retrieve all the tables in the oracle database, so I can choose from them to convert to mysql. It seems that the structure in oracle usually have the tablespace information, I don�t know if I can create database in mysql using this tablespace information. And I don�t know where I can find the information about the functions in JDBC? For example, how to retrieve the table structure? Once I retrieve the table structure and create the exactly same table structure in mysql, then I can fetch all the data in oracle table to mysql table.
Any hint will be great appreciated!
Merry Christmas and Happy new year!
Sammy

Hi, beattris and rtg54,
thank you very much for your great help!
beattris, do you know if there is any such kind of tool free? I am a student and don't want to do commercial product, as you see, my work is very simple, in fact, just as you said, the most important of all is how to get the database structure from oracle schema? do you have any idea about this? or do you know any tool that is open source? so I can learn from it.
rtg54, I just want to convert the database from oracle to mysql, after that, I can use mysql database as storage instead of expensive oracle database. the problem is that I have some data stored in oracle database and the application is built on oracle, after the convertion, I can use mysql to provide data to jsp or servlet application. I will great appreciate if you can contact with mysql about this problem because I don't know how to contact with them.
thanks again and happy new year!
Sammy

How to insert a bean variable into MySql using jsp

Hi, I have a problem that I have been trying to work out for ages..unsuccessfully.
My web-site takes 2 inputs off a user...does a calculation on them and returns the result to the user.
I want to then use another jsp page that will take this result and insert it into a database...
My class code for this is :
public void updateRepmax(String userName, String repmax) throws SQLException, Exception{
     if(con != null){
     try{
     PreparedStatement update;
     update = con.prepareStatement("UPDATE repmax SET Benchpress = ?, WHERE Member_Name = ?");
     update.setString(1, repmax);
     update.setString(2, userName);
     update.execute();
     } catch(SQLException sqle){
     error = "SQLException: could not update repmax";
     throw new SQLException(error);
     catch(Exception e){
     error = "An exception occured while updating repmax";
     throw new Exception(error);
     } else {
     error = "Exception: connection to database was lost";
     throw new Exception(error);
My JSP is :
<%@page import="java.sql.*, placement.*"%>
<jsp:useBean id="conn" class="placement.DBConnect" />
<jsp:useBean id="query" class="placement.DBQuery" />
<jsp:useBean id="bpcalc" class="placement.repmaxBean" />
<jsp:useBean id="userin" class="placement.User" />
<html>
<head><title>Update Repmax</title></head>
<body>
<%
conn.connect();
     String repmax = bpcalc.getRepmax();
     String userName = userin.getUserName();
query.setCon(conn.getCon());
     query.updateRepmax();
conn.disconnect();
%>
     </body>
     </html>
The variable I am tryin to insert is repmax ,in the class that does the calculation the repmax is a double so I assume that is my first problem(how can this be changed to allow it to insert?)....any help you have to offer would be greatly appreciated...

Thanks for your reply sathishkb,
I am not actually receiving any error message,
The jsp page is processed and the code seems to be correct however the table in my mysql database is not updated.. my JDBC drivers are working correctly etc.
I expect that the problem is in my JSP page but dont know what it is
I have removed that comma in my update statement
I no longer have the problem of the variable being of type touble as I altered my other code to convert the variable from double to string
jsp is now:
<%@page contentType="text/html"%>
<%@page import="java.sql.*, placement.*"%>
<jsp:useBean id="conn" class="placement.DBConnect" />
<jsp:useBean id="update" class="placement.DBQuery" />
<jsp:useBean id="bpcalc" class="placement.repmaxBean" />
<jsp:useBean id="currentuser" class="placement.currentuserBean" />
<html>
<head><title>Insert Into Repmax</title></head>
<body>
<%
String repmax = bpcalc.repmax;
String userName =currentuser.name;
conn.connect();
     update.setCon(conn.getCon());
     update.updateRepmax(repmax,Username);
conn.disconnect();
%>
     </body>
     </html>
the segment of my bean code is :
public void updateRepmax(String repmax,String userName) throws SQLException, Exception{
     if(con != null){
     try{
     PreparedStatement update;
     update = con.prepareStatement("UPDATE repmax set Benchpress = ? WHERE Member_Name= ?");
     update.setString(1,repmax);
     update.setString(2,userName);
     update.execute();
     } catch(SQLException sqle){
     error = "SQLException: could not update employer";
     throw new SQLException(error);
     catch(Exception e){
     error = "An exception occured while updating employer";
     throw new Exception(error);
     } else {
     error = "Exception: connection to database was lost";
     throw new Exception(error);
}

How to convert Oracle charset database

I have a Oracle database which set charset "WE8ISO8859P1". how can I convert to "SJIS" charset that dont need create new database

You can't.
You can successfully convert an Oracle database's charset without database recreation if and only if 1) the original charset is a strict subset of the final charset (the letters in the set) and 2) the codepoints (the numbers that encode the letters) in the original charset don't change in the final charset and 3) all of the data in the database actually is encoded in the original charset (or at least is correctly encoded in the final charset). This is because this type of conversion is accomplished by simply slapping a new charest lable on the database as a whole; none of the binary values in the data get looked at, much less touched. If you "convert" a database and all three are not true, then some or all of your string data becomes complete and utter garbage.
For WE8ISO8859P1 to SJIS, both 1) and 2) are false.
3) becomes an issue because of what Oracle calls an optimization and I call a stupidity; when a database recieves string data from a client that asserts it's using the same charset, nothing checks that the data passed is actually in that charset; thus is it's trivially easy to get 8-bit data in a 7-bit US7ASCII database; it will read and write correctly until the day you try to convert to a superset of US7ASCII, such as UTF8. Then WHAM! Data corruption.
Oracle customers with support contracts can get a lot of documentation about character set conversions from the Metalink support site. Oracle also strongly recommends that customers file a support request for conversions (although someone who reads all the docs and understands character encoding and the NLS settings can muddle through on their own). Oracle also has lot of free documentation about globalization and character sets on the OTN site, which just requires a registration, but I'm not sure the nitty gritty details are there.
For non-subset conversions, the way to do it is to export the data, create a new database and import the data. Conversion to the new encoding will occur on import.
There is a utility, CSSCAN, that can be used to prepare for a conversion. It will scan the database for strings that will have difficulty converting.
Besides the possible issue of data that is outside of the original charset, it will also check for data that will be truncated on conversion. By default, the size specification of a VARCHAR2 in Oracle is the number of bytes; when a character is converted, it may expand the number of bytes that it requires, for example when switching form a 7 or 8 bit encoding to a 16 bit encoding. If enough characters in a value are expanded, the data exceeds the size of the column and is truncated or dropped (I forget). Recent Oracle versions lets you change from having the DB count size in bytes to counting size in characters; I don't yet know if this plays nice with imports with character set conversion (I'll know in a few months).

How to convert oracle timestamp to java timestamp

Hi,
I need to convert oracle timestamp that i got from oracle database to java timestamp.I tried to use getTimestamp() to get timestamp value from oracle, but am getting NumberFormatException.
Could any of suggest how to convert oracle timestamp to java timestamp.

Thanks jverd ,
then my code will be like:
String oracleTS="11-MAR-05 11.19.20.625 AM";
// am looking for yyyy-MM-dd HH:mm:ss format
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd
HH:mm:ss");
Timestamp javaTimestamp=Timestamp.valueOf(oracleTS);
System.out.println("javaTimestamp----->>
"+javaTimestamp);
ving java.lang.NumberFormatException: For input
string: "MAR"Well, the SimpleDateFormat has to actually match the format you're trying to parse, for one thing. Then you have to actually USE the SDF, which you didn't.
You really haven't made it clear what you're trying to do, and it doesn't appear that you bothered to study the links I provided.
DateFormat df = new SimpleDateFormat("dd-MMM-yy HH.mm.ss.SSS aa");
Date date = df.parse(oracleTS);
Timestamp ts = new Timestamp(date.getTime());

How to convert logical standby database to Physical Standby Database

Hi,
Does anyone know how to convert logical standby database(10.2.0.3) to Physical Standby Database(10.2.0.3)? Is this possible? If so,please give me steps for it.
Thanks.
Regards,
RJ.

I don't believe this to be possible. One of the steps invloved in the creation of a logical standby is the following:
ALTER DATABASE OPEN RESETLOGS;
This makes the logical standby a different incarnation of the db from the primary.
A physical standby is a binary copy of a primary db, a logical standby is a completely seperate db that just happens to get sql statements applied to it that are generated from a primary db, but is open read/write.
One avenue, though would be if you had flashback database enabled and you flashed back all the way to when the db was a physical standby and then rolled forward with the archived redo logs.
It's somewhat unlikely you are in that situation, but that is a possibility.
Indeed the 11g snapshot standby does this sort of thing:

How to convert Oracle reports previewer output into delimited file.

How to convert Oracle reports previewer output into delimited file if the report has more than 1000 pages.
I tried with previewer option File --> Generate to file --> Delimited file, but the report engine is crashing.Not generating .TXT file.
I observed that this option is not working for more than 400 pages.
I am using Oracle reports 6i version.
Plz suggest me to generate .TXT file from Report previewer.

You can specify a delimiter (a character or string of characters) to separate the data (boilerplate or field objects) in your report output in either of the following ways:
On the command line using the DELIMITER keyword.
In the Delimited Output dialog box or DelimitedData Output dialog box (displayed with File > Generate to File > Delimited or File > Generate to File > DelimitedData) in Reports Builder.

There is no automatic way to do this in JDeveloper. I know there are some Oracle Partners offering forms to java conversion, I don't know how much of their tools are automated and done with JDeveloper. With JDeveloper+ADF you basically rewriting the Forms application from scratch (and using ADF is helpful during this process).

How to install oracle 'sample' database?

hi
i want to know how to install the oracle sample database.i am using oracle 9i installed in win XP pro.I have already installed an empty database named 'orcl.world' by following the steps given in 'oracle by example' link http://otn.oracle.com/obe/paa/index.html/
But its empty and i wanted to install the sample database provided by oracle in order to start practising PL/SQL.
thanks!

I'm assuming you want to install the sample schemas since you already installed the database. The standard install includes these sample schemas, but if you're sure you don't have them, you can take a look at this link which will walk you through the steps http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96539/installa.htm#4371
