Copy Data SQL Server to Oracle

Hello Gurus,
I need to migrate a data i.e only1 table from sql server to oracle 9.2.0.1.0. I've created system DSN connection also, but not working. I've tried all methods of destination like
1. Oracle Provider for OLE DB.
2. Microsoft ODBC Driver for Oracle.
But not able to get data into Oracle Table.
SQL Server gives message data transferred to Oracle.
But when queried, no rows selected.
Response required.
Thanks

Show data from sql server to oracle db

Hi,
I am using oracle 10g R1 on windows 2003 platform. On one machine database 10gR1 is running and on other machine sql server is running. I want to retrieve some data from sql server to oracle database. Please tell me how I can show data from sql server to oracle db.
Thanks

To make heterogeneous connection with oracle:
1.First make an ODBC connection, make entry in System DSN(to create a data source)
2.Make an entry in tnsnames.ora
3.Make an entry in listener.ora under SID_LIST_LISTENER
4.Make an entry in file named init<HS>.ora file located "oracle_base\oracle_home\db\hs\admin"
5.Restart the listener
e.g:
1. create a odbc system dsn named like 'sqlserver'
2. sqlserver= (DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp) (HOST=xx.xx.xx.xx) (PORT=1521))
(CONNECT_DATA = (SERVICE_NAME=sqlserver))
(HS = OK)
3. (SID_DESC = (SID_NAME = sqlserver) (ORACLE_HOME = oracle_base\oracle_home\db) (PROGRAM = hsodbc) )
4.Create a file named initsqlserver.ora and make the following entry:
HS_FDS_CONNECT_INFO = sqlserver
Alternatively, you can copy the file named inithsodbc.ora and rename it to initsqlserver.ora
and edit as HS_FDS_CONNECT_INFO = sqlserver
5. lsnrctl reload listener_name

How to replicate data from MS SQL Server to Oracle

Hi,
Can someone please help me on how to replicate data from MS SQL Server to Oracle 8i database.

Dear,
I'm a student.
I do simple replication on Oracle 8.0.5 successfully. (one master site and one snapshot site). I only use the SQL*Plus and Schema Manager to do.
But when I do advance replication (multimaster replication) I meet many problem. So I don't get the result.
Do you show me the technology to do that ?
Thanks !

How to extract incremental data from SQL server to oracle tables in ODI

HI All,
In my ODI sql server is install.My Source is in SQL server and my target is in Oracle.
I need to create a interface mapping where i need to extract incremental data from sql server to oracle.
There is a datetime(with Timestamp) field in sql server .I need to pull incremental data based on dateime.
Example = tablename.DateTime > (select '1-jan-11' from dual) .....i am using this query but its not woking.the error is Invalid object name"dual".
We are not going to use Incremental in IKM and LKM.
Request you to please provide any suggestion ASAP.
Thanks,
Lony

You can do that via Variable.
In the interface mapping create a filter on Tablename.DateTime
and put the condition like this
Tablename.DateTime BETWEEN #VAR and in the variable use this query in refreshing tab with oracle schema
SELECT max(start_time)||' AND '||max(END_TIME)+1 from audit_table where ETL_JOB_CODE = '20'In the package call the above variable in refresh mode and then interface.
This way you will pass from the query between and condition date and pass to interface so that SQL Server fetches the data between those too range.
Note:- You might need to tweak the date format so that SQL Server can understand.
Hope this helps.

TRANSFER DATA FROM MS-SQL SERVER TO ORACLE

hello everybody
can anyone tell me how 2 transfer or convert data from ms-sql server to oracle
is there any utility
if yes let me know .
thanks in advance

There are various options depending on how much data we're talking about, where you want the program logic, whether it's a one-time migration, etc.
Among the options
- Use SQL Server's DTS
- BCP the data from SQL Server into flat files and use SQL*Loader to load it
- Create a database link using Heterogeneous Services and Generic Connectivity to extract data from SQL Server
- Use the Oracle Migration Workbench, which is now integrated into SQL Developer
- Use an ETL tool like Oracle Warehouse Builder

Faster way to migrate data from SQL Server to Oracle 10g

We have to migrate data from SQL Server to Oracle 10 g.
One particular table on SQL Server has records around 1.25 millions.
We tried moving data using DTS package, but looks it will take hours with current speed of 300 records/minute.
This table has TEXT column, which has XML strings stored. I am not sure, if this is the reason for slow migration.
Would you please suggest better options to migrate it faster?
Thanks in advance !!!

Have you tried Migration work bench?

Transfering Data from SQL Server 2 Oracle

Hellow All,
Even the subject is not here, but i'm trying to transfere data from SQL Server to Oracle 8 (8.0.6) .. using the Wizard that ships with MS SQL Server. All Connections (ODBC or OLE DB) are alright, but still have problems in moving Data .. and Failure.
Failure in Data Movement and not in Table structures.
I have tried using most of the Valid and consistent ODBC and OLE Providers from Microsoft & From Oracle... but still have problems.
Even The Oracle Migration Assitiant from Access 97 dose not work properly.
Any commenets please ???

Anil,
OMWB has an inbuilt collision manager, that will check for conflicting words and aptly replaces them with an alternative word.
OMWB also allows users to change these words once you finish performing capture. In this particular case, when you capture the view with the name 'rule', you can go to the oracle model in omwb and change the name to "rule1" or anything that is desirable, preferably those words that do not conflict with the oracle d/b's reserved words.

Replicating data from SQL Server to Oracle

I like to know whether it is possible to Replicate data from SQL Server to Oracle and vice-versa.
My present application is using SQL server and very recently we migrated to Oracle. As the usage of SQL Server is more, I like to replicate the data being entered into SQL Server into Oracle also.

You can also use SQL Server replication right out of the box to replicate data to Oracle. In Enterprise Manager, configure an OLE-DB or ODBC subscriber with the Oracle credentials, and then just create a standard push subscription to the newly configured Oracle subscriber. Note that you need to click the advanced checkbox on the subscription wizard to see the heterogeneous datasource as a subscriber.
Good luck,

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.

vhiware wrote:

and its taking long time.... but its running...I doubt that parallel processing will be used as this is unique to Oracle (using rowid ranges typically) and not SQL-Server.
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.

How to merge data from SQL server to Oracle Database

Dear Expert,
I am having problem with SQL server with Oracle.
Problem: I want to merge table records from SQL server to Oracle Table. Which License free tool I can use to achive the goals.
If I able to make a free DB link from Oracle to SQL server , then we can select table and will be able to update.
Right now I have made a DB link from SQL server to Oracle, Using that I can see the records from oracle database but I can't update them.
Thanks,

Migration from SQL server to Oracle

Hi,
Has anybody done migration from the SQL server to Oracle? If so, what manual method do you recommend? I'm a new college grad and I would like to get your expertise, if you have done this in the past.
Thanks in advance!
Sho

It is some time back, so I do not remember the specifics. Oracle gives Oracle Migration Workbench for free. You can use it to convert all SQL tables and procedures etc to oracle. It is not that difficult. If there are no stored procedures etc, you can just extract the DDL and create the tables with minor changes to the script. You might need bcp-sqlloader/trasparent gateway etc copy the data.

Database independant ETL in ODI for SQL Server and Oracle

Hi,
We have a requirement to create ETL which can be run for both SQL Server and Oracle.
We have some tables to be filled from operational database to data warehouse using business requirement.Our goal is to create code which should be database independant.
We will provide all DB details at the start of execution and it will code for as per provided details.
The same can be achieved by Talend.
I wanted to know if same can be achieved in ODI.
Any pointers regarding this would be helpful.
Thanks,
Mahesh

A quick trick: Provide one more value at the start of execution. It is something like a flag. For example db_flag. It can be either 'O' or 'S'.
Open both oracle and sql server KM. Copy one of the KM code to other KM and put an if condition to check the flag.
if (#DB_FLAG.equalsTo("O")){
Oracle code goes here...........
}else{
SQL Server code goes here...........
Its a pure KM customization.

Problem with migrating data (SQL Server 2k offline data capture)

Hi there,
I try to migrate a SQL Server 2000 database to Oracle 10g (R2) using offline data capture. I following the online Tutorial “Migrate from Microsoft SQL Server to Oracle Database 10g Using Oracle Migration Workbench” and everything seems OK until “Migrating the tablespaces, users and user tables to the destination database” http://www.oracle.com/technology/obe/10gr2_db_vmware/develop/omwb/omwb.htm#t5. I have two errors on 2 (out of 85 ) tables saying “ Failed to create default for Table :
ORA-00907: missing right parenthesis”. I checked the column/table names and they seems OK. I don’t understand why I got these errors. However, when I checked the ‘SA’ Schema in Oracle Enterprise Manager Console, I can see all the tables (including the two problem ones).
I then carry on to the next step and tried to migrate data to the destination database (http://www.oracle.com/technology/obe/10gr2_db_vmware/develop/omwb/omwb.htm#t6) I am now stuck on step 5. “…copy the files from c:\omwb\data_files to the c:\omwb\Omwb\sqlloader_scripts\SQLServer2K\<timestamp>\Oracle directory…” I cannot find the ‘c:\omwb\data_files’ directory, in fact, I don’t have a directory called ‘data_files’ on my machine. I noticed the ‘c:\omwb\Omwb\sqlloader_scripts\SQLServer2K\<timestamp>\Oracle’ directory contains the all the 85 [tableName].ctl files (plus two other files: ‘sql_load_script’ and ‘sql_load_script.sh’). From the screenshots online, ‘c:\omwb\data_files’ seems contains files with the same name as the [tableName]. Therefore, I did a search with [tableName] but cannot find any apart from the [tableName].ctl file in the ‘c:\omwb\Omwb\sqlloader_scripts\SQLServer2K\<timestamp>\Oracle’ directory. What should I do next?
OS: windows 2003 with SP1
Oracle: 10g Release 2
SQL Server 2000
Any help would be extremely appreciated.
Helen

Helen,
Sorry, I am new here. Could you please tell me (or point me to the related documents about) how to output the Oracle model as a script?Action-> Generate Migration Scripts
And what do you mean by ‘The default conversion may have failed’? Do you mean data type mapping? I went through all the columns and tables and checked the data types in the Oracle model already. The processing for the default for a table column could have something the basic workbench default parser cannot handle.
I hope you are finding the workbench to be a productive aid to migration.

Depending on the version of the database you have, you could use transportable tablespaces.
