Unsupport feature SQL exception ---JDK1.4 and oracle 10g driver

here there,
I got the unsupport feature SQLexeption, does anybody have any idea? JDK1.4 and oracle 10g driver should fully support JDBC 3.0. Am I right ?
Thank you very much
Avni
here is my snippet code,
Connection con = DriverManager.getConnection(url, user, password);
          DatabaseMetaData data = con.getMetaData();
          int jdbcVersion = data.getJDBCMajorVersion();
and here is the exception,
java.sql.SQLException: Unsupported feature

Avni,
Works for me with Oracle 10g database, "ojdbc14.jar" JDBC driver (latest version -- 10.2.0.1.0 -- downloaded from OTN) and JDK 1.4.2_07:
conn = ods.getConnection(); // Using 'OracleDataSource'
DatabaseMetaData dbmd = conn.getMetaData();
System.out.println("JDBC Major Version: " + dbmd.getJDBCMajorVersion());Above code prints out:
JDBC Major Version: 10Good Luck,
Avi.

Migration from of database and app from SQL server 2005 to Oracle 10g

Hello Every body,
Lately, I have been requested to migrate one inhouse developed hub application from SQL server 2005 to Oracle 10g. The objective is to move application and also the database to Oracel 10g.
Here is the current platform:
OS Win 2008 64 bit
JDK 1.4.2
JBoss 3.2.5
EJB 2.1
My question is what kind of issues you guys see in above upgrade. As far I know, Schema and Database migration can be done by Oracle workbench. Oracle 10g supports JDK 1.4. Oracle 10g also supports EJB 2.1.
Anything, I need to take into consideration or any risks or problems. I would like to list down all the risks, and accordingly, I am thinking of start the upgrade.
Thanks in advance.
Regards,
Zeeshan Qureshi

In general the Java/J2EE application needs work in the following categories:
1. Connection Settings: Use Oracle JDBC drivers, create new data sources, connection pools and what not. Disable AUTOCOMMIT for Oracle JDBC Connections.
2. For EJBs, you should regenerate the entity beans because some object names/column names might have changed in oracle.
3. Any custom SQL that is in use in the EJBs will have to be ported to Oracle just as you would do in stored procedures and other applications.
4. For Java front-ends, if you are using callouts to stored procedures and expecting result sets then they will require some changes. You need to modify the stored procedure call signature to include the REF CURSOR variables and process them.
5. Changes to any SQL Server specific database functions manipulating character/date data will be required.
6. CLOB/BLOB/XML apis are different across databases so if you are using those then focus on them as well.
7. Retreiving Auto/generated keys from database also may need changes from what I have seen.
Hope this helps..

Problem in Loading Data from SQL Server 2000 to Oracle 10g

Hi All,
I am a university student and using ODI for my final project on real-time data warehousing. I am trying to load data from MS SQL Server 2000 into Oracle 10g target table. Everything goes fine until I execute the interface for the initial load. When I choose the CKM Oracle(Create unique index on the I$ table) km, the following step fails:
21 - Integration - Prj_Dim_RegionInterface - Create Unique Index on flow table
Where Prj_Dim_Region is the name of my target table in Oracle.
The error message is:

I am using a surrogate key column in my target table alongwith the natural key. The natural key is populated by the primary key of my source table, but for the surrogate key, I have created a sequence in my oracle schema where the target table exists and have used the following code for mapping:
<%=snpRef.getObjectName( "L" , "SQ_PRJ_DIM_REGION" , "D" )%>.nextval
I have chosen to execute this code on target.
Among my attempts to solve this problem was to set Create Index option of the CKM Oracle(Create Index for the I$ Table) to No so that it wont create any index on the flow table. I also tried to use the simple CKM Oracle km . Both solutions allowed the interface to execute successfully without any errors, but the data was not loaded into the target table.
When I right-click on the Prj_Dim_Region data store and choose Data, it shows empty. Pressing the SQL button in this data store shows a dialog box " New Query" where I see this query:
select * from NOVELTYFURNITUREDW.PRJ_DIM_REGION
But when i press OK to run it, I get this error message:

Hi Cezar,
Can u plz help me with this scenario?
I have one Oracle data model with 19 source tables and one SQL Server data model with 10 target tables. I have created 10 interfaces which use JournalizedDataOnly on one of the tables in the interface; e.g in interface for DimCustomer target table, I have 2 tables, namely Customer and Address, but the journalizing filter appear only on Customer table and this option is disabled for Address automatically.
Now I want to create a package using OdiWaitForLog event detection. Is it possible to put all these 10 interfaces in just one package to populate the target tables? It works fine when I have only one interface and I use the name of one table in the interface for Table Name parameter of OdiWaitForLogData event, but when I try a comma seperated list of table names[Customer, Address] this error happens
java.sql.SQLException: ORA-00942: table or view does not exist
and if I use this method <%=odiRef.getObjectName("L","model_code","logical_schema","D")%>, I get this error
"-CDC_SET_NAME=Exception getObjectName("L", "model_code", "logical_schema", "D") : SnpLSchema.getLSchemaByName : SnpLschema does not exist" "
Please let me know how to make it work?
Do I need to create separate data models each including only those tables which appear in their corresponding interface and package? Or do I need to create multiple packages each with only one journalized interface to populate only one target table?
Thank you for your time in advance.
Regards,
Neel

How to block Sql Plus sessions in Oracle 10g

Hi,
I want to block all sql plus sessions in oracle 10g, as we have a application and we need each and every one to use this application not the sql plus session.
Kindly update us as soon as possible. and also thanks in advanced.

Understand the concept Karl, but a layered defense seldom works in the IP world. If I manage to get through the firewall, then how can you prevent me access, at IP level, at any other ISO stack layer? If you manage to get through, then your firewall policies could just be too weak :) at least you must have some kind of an IDS infrastructure in place..
what I mean is, you can have infinite number of threats.. and this will be part of your Risk Analysis. Determining all possible threats to the assets, what are being protected and their associated value, and predicting the rate of occurrence.... with all of these you could probably come up with contingency plans and incident response.. And most of all, you should not ignore the fact that people are creative, ingenious, and curious, and they'll prove this to you by testing your security implementations. So you'll have to periodically evaluate your security.. that's why there are audits.. Also, you must balance Security, Performance, Usability, and your Budget.
Yes, you can argue that if the entire firewall goes down (thus no IP defense), then something like DBV (or even denying IPs in sqlnet) can provide some defense. But is that not then a case of too little too late? It's better too little too late, than no protection at all... Imagine if there's no DBV, or if you have not implemented the concept of "Least Privilege"? or if the backups and exports are not encrypted? That would be more devastating.. that's the importance of database security options and features in providing "defense in depth"
I question just what purpose and how effective IP packet security is at higher layers. It can never substitute doing this instead at firewall level. Well, it's not all about network security. All facets must be considered and the inter-relationships should be understand. Like the core information security and access management, physical and personnel security, training them, etc... And all of these are equally important in providing a secure ecosystem
As for security that relies on the client to pass secure data (like executable name or o/s user name)... all this can easily be spoofed. Even if the app and Oracle driver are somehow digitally signed and these signatures can be verified on the server side, we only need to look at Vista to see how secure this really would be. Microsoft attempted to encrypt every single h/w and s/w layer from the physical DVD track to the pixel on the monitor.. and this was defeated. And this was done as o/s kernel level. It is less complex to hack at driver level and even trivial to do it at application level.Security is about risk management. Blocking SQL*Plus does not negate the risk of SQL from the wild being run on a production server. For example, the client is a VB client using ODBC. It is easy to create a proxy that accepts the ODBC connection from the VB client and proxy the OCI packets to the real Oracle server. Now you have a man-in-the-middle than can inspect every single SQL call made to Oracle, and inject any PL/SQL or SQL code it wants.
Security is far beyond writing a login trigger to deny SQL*Plus sessions and calling that a defense. >
Yes I agree with you. That's why there are independent organizations and regulating bodies that provides security best practices, to give us a headstart on comming up of strong security policies.
And one of my favorites is the one provided by IASE (sponsored by Defense Information Systems Agency) where there's lot of content regarding hardening and policies

General question on SQL Server 2000 to Oracle 10g

Hello all,
I just have a general question on migration from SQL Server 2000 to Oracle 10g using SQL Developer.
How does it migrate Users with proper privileges from SQL Server to Oracle? Follow the interface steps? Or should the users be created on destination Oracle side?
Thank you.

Hi,
It depends which type of migration you are making.
For a 'Standard' migration when you migrate data a 'create user' statement is created as part of the migration and you will see this in the generated code.
If you are using the 'Quick' migration option then you need to create the Oracle user or use an existing user to receive the data.
Your best option is to review the documentation available from -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
or directly from -
http://download.oracle.com/docs/cd/E12151_01/index.htm
and then get back with specific questions if this does not give you the information you need.
Review the chapter -

Move data from sql server v8 to oracle 10g

I just got urgent projects to migrate the data from MS SQL server 2000 to oracle 10g. The following are requirements:
Source data/table: MS sql server 2k (version 8) on MS 2000 machine.
Destination Data/table: oracle 10g (10.1.0.4) on Redhat version 3.
Total number of tables: < 10 tables and < 1000 rows each tables.
This is only one time data extraction. No periodically data extraction need.
Questions:
What connect method I should use? (odbc or jdbc)
What if I have image datatype?
Thanks in advance.

Use the Oracle Migration Workbench.
http://www.oracle.com/technology/tech/migration/workbench/index.html
I think IMAGE will be migrated to BLOB by default.

Migration from SQL Server 2005 to Oracle 10g

Dear buddies,
I need to migrate my tables with data from SQL Server 2005 to Oracle 10g. How can I do it in the best possible way?
Please guide me.
Nith

Nith,
I doubt if there is one best practice that can cover all cases of migrating data from sql server to Oracle. l generally find various factors case-by-case that make me chose one approach over the other. Without considering the business case and environment specific factors, some of the things I would like to know would be: The data types of the tables columns, table sizes, number of tables and if this is a one time process or a recurring process.
One of the easiest (some times rather pesky) process would be:
-Dump source data (Sql Server data) into flat files, csv or any preferred format
-Setup a set of staging set of tables in the destination DB (Oracle in your case). You can setup the stage tables to enforce data-types, value sets and even some level of integrity constraints or any data logic or what ever you would like to filter out. Load the flat file data into a set of Oracle stage tables (Sql*Loader would be a good candidate)
-You can always move data from these stage tables to you application tables
You can script this whole process to run as batch or on demand or how ever you would like.
I am sure you can google and find a bunch of proprietary as well as open source tools to do the same with little to a lot of work.
good luck!

Migration from SQL SERVER 2008 to Oracle 10g issues.

Hi ,
I'm trying to migrate from SQL Server 2008 to Oracle 10g and I end up with some issues that I wanted to ask some info about it.
First, I was following a tutorial
http://st-curriculum.oracle.com/obe/db/hol08/sqldev_migration/mssqlserver/migrate_microsoft_sqlserver_otn.htm
and and in the last version of Oracle SQL developer I downloaded, I didn't find the Load Database Capture Script Output option.
My first question is how can I either add this option or is there a new way to load the capture script ?
Then I use the migration wizard and after following everything, I had the migration complete message from the application.
When I tried to open my connectionss, it tells me version 11.2 is required. Does that mean that Oracle SQL developper 3 only
do the migration for oracle 11g? And if I tried the previous versions, it doesn't support SQL server 2008.
What do I do in this case ?
Thanks !

Thank you for your reply.
After using the wizard and made the offline migration script, in the Migration projects window I made a move data to the oracle connection I previously made and after when I tried to reopen the connection, I couldn't.
Well I didn't retry it yet to see if I'll have the same behavior but basically this is what I think I did. When I tried to open the connection I made, it says, Oracle 11.2 is required.
Now, I just generate target from the convert model and it says migration complete but how do I test it and I do I go to oracle and see change ?
Do I had to create a special user in SQL Server to log to it first ? How do I logon to it ?

Migrate tables from Ms SQL Server 20005 to Oracle 10g

Hi all,
I am trying to migrate 10 table from Ms SQL Server 2005 to Oracle 10g. I started creating a SSIS package to transfer them but it always fail when it tries to create the tables.
Questions:
- Is there any other way to import Ms SQL Server 2005 tables to Oracle
- also I need to create a scirp that will update these tables periodically
any ideas?
Thanks

YingKuan is right. jsut to expound a little further. This will also allow you to have have scripts which you can run again and again or even schedule them regularly too.

Trying to migrate SQL Server 2000 to Oracle 10g.

Hi.
I´m trying to migrate from Sql Server 2000 to Oracle 10g and I got some troubles.
I have connected both databases with my Oracle Sql Server, after that I went to the Menu--> Migrate--> Fast Migration and then fill all the steps necesary.
I can see the repository`s table at the oracle schema but after that the Sql Developer hang at the point "capture". I let the tool work for 2 hours and nothing to do. It´s not a hughe db so could be done faster.
May I miss something?.
Thanks.

Hi
I also have similar issue when trying to migrate from MS SQL 2005 to oracle 10g.
I use the SQL Developer Version 2.1.0.63.
First, I tried to use 'Quick Migration' then it created repository then stop there with error message
"Error ocurred during capture: ORA-01400: cannot insert NULL into ("DDHCOWNER"."MD_PROJECTS"."ID")"
Then, try manual way to capture SQL server, but some how it doesn't work. It just refresh IDE and stop.
Before this activity, I tried to migrate MS SQL 2005 using 'Quick Migration' and it works. But this time I have to do it on another DB then this happened.
So I re-try the previous connection then encountered the same to all.
Thus, please kindly help to advice how to solve this problem.
Thank you so much.

Our Java application is built with java 1.4 version and oracle 10g

Our Java application is built with java 1.4 version and oracle 10g version database, is it possible to upgrade oracle database to 11g?

is it possible to upgrade
Yes. SE and the other editions have a migration/upgrade utility, not seeing any mention of that program in the XE license docs. To upgrade to 11gR2 from 10g, the 10g instance must be at patch 10.2.0.2 or higher.
So if you're a GUI dba, might be out of luck. But the the XE install has the catalog upgrade scripts that need to be run, there is a MOS note explaining the manual upgrade steps.
Or set up a brand new 11g database instance and datapump your user schema(s) from the 10g instance to the new 11g instance. The database doesn't care what java version you're using, it just does what its told with the data. DDL, DCL, DML ... its not much different. Quite a few new features in 11g.
But if you're after JVMs that piece is not supported with XE.
