Insert data from SQL Server 2008 St.Ed to ORACLE 11gr2 St. Edition

Dear all,
I'm searching a solution for faster transmission of data of a db SQL Server (2008 St. edition) vs PROD db that is an ORACLE 11gr2 St. edition too.
Actually this operation spend 1,5 hours but I'd like cut this time because size of the data grow up in future and this time could be a serious problem ....
Looking on Oracle Enterprise Manager I've seen that main problem is about commit .. SQL Server every record insert into Oracle TBL generate a commit ... unfortunately I cannot insert when commit must be done ... If will be solved it probably may be solved situation ...
Thanks in advance for every idea.

REDO upgrade was done like first step because anyway it was too small.
Thanks for you answer and sorry again for delay !!!!
Thanks.
If you are depending on MS SQL server technology to do this, you are going to be stuck with the performance of that technology.
A few weeks ago we had a need to load institute a daily load of or DW from a MSSQL database. The MS-centric person responsible developed a procedure (using MS tools) that took 4.5 hours to load 1.2 million rows. I ran a session trace and the tkprof report revealed exactly what has already been described. Single row insert and commit. I knocked together a PL/SQL procedure that did a single INSERT .. (SELECT .. FROM TABLE@MSSQL). and it ran in 4 minutes. Using the Oracle transparent gateway for ODBC.

JDeveloper 11.1.1.2.0 - Panel Dashboard using Data from SQL Server 2008

Hi All,
I am using JDeveloper 11.1.1.2.0 and am trying to create a cross application dashboard. This dashboard would show 2 panel's of data from an Oracle Database (Already completed this) and two panel's of data from a SQL Server 2008 Database.
I have successfully installed a SQL Server 2008 database locally on my machine. I have downloaded the JDBC drivers from the Microsoft website and I have two JAR Files:
* sqljdbc.jar
* sqljdbc4.jar
I have created a SQL Server connection within the JDeveloper connections panel and I can successfully query my database.
I have created a New application module and set its connection to a JDBC connection with the credentials specified within the Connections tab. I then added the two JAR files as libraries to the Model project and
ran the Application Module tester. This succesfully shows some records.
Within the View Project I Created a new page and dropped the View Object on as a table. I then go to Run the page and get an error relating to the JDBC drivier not being found. I have read a few posts about adding it to Weblogic lib files and modifying the start up scripts but can anyone give me a definitive working solution? I also tried changing my Application Module to using a DataSource, but I also have the same problem within the Weblogic console (it cannot create a data source for SQL SERVER as it does not have the drivers).
Any help is greatly appreciated.
Thanks

Thanks for the responses.
I have edited C:\oracle\Middleware\wlserver_10.3\common\bin\commEnv.cmd to add the entries as follows...
set WEBLOGIC_CLASSPATH=%JAVA_HOME%\lib\tools.jar;%BEA_HOME%\utils\config\10.3\config-launch.jar;%WL_HOME%\server\lib\weblogic_sp.jar;%WL_HOME%\server\lib\weblogic.jar;%FEATURES_DIR%\weblogic.server.modules_10.3.2.0.jar;%WL_HOME%\server\lib\webservices.jar;%ANT_HOME%/lib/ant-all.jar;%ANT_CONTRIB%/lib/ant-contrib.jar;%WL_HOME%\server\lib\sqljdbc.jar;%WL_HOME%\server\lib\sqljdbc4.jar
You can now see the additional entries at the end of the classpath.
The Weblogic home is set as follows set WL_HOME=C:\oracle\Middleware\wlserver_10.3
I have placed the files in C:\oracle\Middleware\wlserver_10.3\server\lib
I restarted the server. Logged into the Weblogic console and tried to create a datasource with the Microsoft Drivers but still no luck. I gave the Oracle Microsoft Driver a go and it seemed to work! I'm guessing that there is a driver bundle in.

How to only migrate data from SQL Server 2008 to Oracle 11?

According to our requirement, We need to only migrate data from a SQL Server database to an existed
Oracle database user.
1) I tried to do it with SQL Developer 3.0.04 Migration Wizard, But find an issue.
My SQL Server database name is SCDS41P2, and my Oracle database user name is CDS41P2;
When I used SQL Developer to do offline move data by Migration Wizard, I found all oracle user
name in movedata files which gotten by run Migration Wizard
is dbo_SCDS41P2. If the Oracle user name is not the same as my existed Oracle user name,
the data can't be moved to my existed Oracle user when I run oracle_ctl.bat in command line window.
So I had to modify the Oracle user name in all movedata files, but it's difficult to modify them because there are many tables in
databases. So could you please tell me how to get the movedata files which the oracle user name in them is my
expected Oracle user name?
2) I also tried to use the 'copy to Oracle' function to copy the SQL Server database tables data
to the existed Oracle database user. When clicked 'copy to Oracle', I selected 'Include Data' and 'Replace' option
But I found some tables can't be copied, the error info is as below:
Table SPSSCMOR_CONTROLTABLE Failed. Message: ORA-00955: name is already used by an existing object
Could you please tell me how to deal with this kind of error?
Thanks!

Hi,
Thanks for you replying. But the 'copy to oracle' function still can't be work well. I will give some info about the table. I also search 'SPSSCMOR_CONTROLTABLE' in the target schema, and only find one object. So why say 'name is already used by an existing object'? Could you please give me some advice? Thanks!

Best way to push change data from sql server to windows/web application

i apologized that i do not know should i ask this question in this forum or not.
i have win apps which will load all data initially from db and display through grid but from the next time when any data will change in db or any data will be inserted newly in db then only change or newly inserted data need to be pushed from db side to
my win apps. now only sql dependency class is coming to my mind but there is a problem regarding sql dependency class that it notify client but do not say which data is updated or inserted.
so i am looking for best guidance and easy way to achieve my task. what will be the best way to push data from sql server to win or web client.
there is two issue
1) how to determine data change or data insert. i guess that can be handle by trigger
2) next tough part is how very easily push those data from sql server end to win apps end.
so looking for expert guide. thanks

Hello,
Yes, you can create DML trigger on INSERT and UPDATE to get the changed data into a temp table. And then query the temp table from application.
If you are use SQL Server 2008 or later version, you can also try to use
Change data capture, which
can track insert, update, and delete activity that is applied to a SQL Server table and store the changed values on the Change Table.

How to delete the Folder from sql server 2008

Hi all,
I was trying to delete the folder from sql server 2008 with the below script
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @cmd VARCHAR(8000)
DECLARE @folderName VARCHAR(256) -- filename for backup
SET @folderName = + (CONVERT(varchar(10), GETDATE()-7, 112)) -- 7 days back date folder name
SET @path = 'I:\Backup_Test\' + @folderName -- Folder path
SET @cmd = 'del ' + @path -- Delete
EXEC master..xp_cmdshell @cmd
--Print @cmd
This is not working it was asking the Confirmation (I:\Backup_Test\20100629\*, Are you sure (Y/N)? ) what will i do to the delete the folder.
Thanks,
Prasad R.

I would notice   you that T-SQL does not play well to do things like that. Do not you want using .net language to delete folders?
Old method is
declare @HR int, @CFOLDER varchar(255),@FSO int
    set @CFOLDER='D:\folder\'
    EXEC @HR = sp_OACreate 'Scripting.FileSystemObject', @FSO OUT
    EXEC @HR = sp_OAMethod @FSO, null, 'DeleteFolder', @CFOLDER
Now regarding to your second question please examine xp_fileexist system stored procedure
CREATE FUNCTION dbo.fn_file_exists(@filename VARCHAR(300))
RETURNS INT
AS
BEGIN
DECLARE @file_exists AS INT
EXEC master..xp_fileexist @filename, @file_exists OUTPUT
RETURN @file_exists
END
GO
-- test
SELECT dbo.fn_file_exists('c:\a.txt')

Error while exporting data from sql server to excel

Hi,
I am trying to export data from sql server to excel.
The query that I used is s follows
INSERT INTO OPENROWSET( 'Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C:\Folder1\abc.xls','select * from [Sheet1$A1:IV65000]')
select
column1,column2.... from Table1
I get the following error message while doing so..
String or binary data would be truncated.
The statement has been terminated.
One of the column's holds data more than 225 characters.
What is the way to correct this, i want the whole data of the colum in the excel sheet.

I haven't had great luck with the INSERT INTO OPENROWSET method. Can you try one of the many samples from one of these 3 links?

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 ?

Import data from SQL Server to Oracle

I have created a dblink in oracle to access the SQL database. I am able to run queries through the dblink and it works fine. I have created a test table on Oracle Server to import the data. The field named "description" has CLOB data type. The corresponding datatype on SQL Server is varchar(7000).
When I insert the data from SQL Server, it completes successfully without any error but it truncates the data on CLOB field.
If I run the select query in SQLPlus I can see the entire description.
Select "description" from sql_view@dblink;
-- the above works fine.
CREATE table test
(description CLOB);
INSERT INTO TEST
Select "description" from sql_view@dblink;
-- this works but it truncates the data after 256 characters
My question is, how to get the data from SQL Server without truncating characters.
Thanks in advance,
Gopal

I hear the same from other friend that sql server truncated the leading zeros from the id column.
I really don't have a solution for this but you can try the work around. Export the data to flat file and upload in oracle using SQL loader, as this would be much faster and efficient.

i have to upload data with some conditions.
not allowed to install oracle client on sql server for link server. i can get data in csv file
which will be the best possible way
1) using Db link on oracle server
2) get data into csv file and load using SQL loader
3) get data into csv and load using external table
4) using tool - sql developer
Thanx,

Have trouble query after creating a linked server from SQL Server 2008 to EXCEL 2007

I created a linked server from SQL Server 2008 Management Studio Express to an EXCEL 2007 workbook using:
sp_addlinkedserver @server='LSERVER_EX0', @srvproduct='EXCELDATA', @provider='Microsoft.ACE.OLEDB.12.0', @datasrc='C:\Temp\abc.xlsx', @provstr='EXCEL 12.0'
The linked server LSERVER_EX0 was created, but I cannot see any table(excel sheet), and when i ran the following to query tables,
sp_tables_ex 'LSERVER_EX0'
I got:Cannot obtain the schema rowset "DBSCHEMA_TABLES" for OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "LSERVER_EX0". The provider supports the interface, but returns a failure code when it is used.
Any hint why?
on another note, i was able to import the EXCEL sheets using the Import and Export Data wizard, but i cannot control the column data type and size in this way.

Open management studio, goto "Server Objects"->"Linked Servers"->Providers, select the provider you use, right click it and in provider options, check "Allow inprocess".

Loading data from SQL server to Oracle database

i want to create one table in oracle db from table in sql server. Table is huge it got 97,456,789 records.
I created db link (HS) in oracle database which is pointing to sql server. i can select that table from oracle thru db link.
select * from "dbo"."t1@dblink;
i fired below create table.
create table t2 nologging parallel (degree=3) as select * from "dbo"."t1@dblink;
and its taking long time.... but its running...
is there any alternate method to do this and and populate table in oracle db faster.
Please advise. thanks.

is there any alternate method to do this and and populate table in oracle db faster.Part of the performance overhead is pulling that data from SQL-Server to Oracle across the network link between them. This can be sped up by compressing the data first - and then transferring that across the network.
For example: using +bcp+ to export the data on the SQL-Server box to a CSV file, compress/zip the file, scp/sftp the file to Oracle, and then unzipping it there. Parallel and direct load processing can now be done using SQL*Loader to load the CSV into Oracle.
If this is a Linux/Unix base system, then the unzip/decompress process can be run in parallel with the SQL*Loader process by creating a pipe between the two - where the unzip process writes uncompressed data into the pipe and SQL*Loader reads and loads data as it becomes available via the pipe.
Alternatively, you can do you own PQ processing. Let's say the data is date ranged. You can create a procedure on Oracle that looks something like this:
{code}
create or replace procedure CopyDay( day date ) is
begin
insert /*+ append */ into local_tab select * from remote_tab@remotedb where col_day = day;
-- add logging info, commit, etc.
end;
{code}
You can now start 10 or more of these for different days and run it in the background using DBMS_JOB.
