Insert data from oracle to sql server
we have running R12.1.1 .
our company wants to deploy some CRM Application with sql server database. Continuously we have to insert data ( some fields from some tables of Order Management module ) from ORACLE -----------> SQL Server
My Questions are :
1. What are possible methods to insert data from ORACLE -----------------> SQL Server ?
2. What are pros and cons of each method ?
3. What is performance over load of each method ?
PLease share your valuable knowledge / ideas / suggestions
thanks
What is a maximal latency for data changed in Oracle come into MS SQL?
this data will be updated in CRM after 24 hours.Does it mean that data replicated from Oracle will be updated in MS SQL and should be replicated back?
i want to know more details about these APIs etc and middle layer.what API? In MS SQL you can use Linked server and write SQLs that select from Oracle tables via that linked server and insert/update/delete into MS SQL. You can organize these SQLs into T-SQL procedures and run them in jobs.
Also you can use MS SQL replication, snapshot or transactional, which is ugly because it places triggers on Oracle tables. I doubt that this will be approved by app vendor.
Also you can use Oracle Streams via Transparent Gateway for MS SQL, which will be quite heavy solution.
Also, if real-time replication is needed, you can use "middle layer" Oracle Golden Gate, which may be quite pricy for 30 tables.
Also, if real-time replication is needed, you can use 3-rd party middle layer like DataCurrents or others.

Inserting Data from Oracle to SQL Server on the Real Time Basis.
Hi Everyone,
I need to insert data from Oracle to SQL Server on the Real Time basis, we have to fetch data from oracle approx 20 tables, and each table has more than 30 Fields. I need to fetch data in every 15 mins.
I have created a job using SQL SERVER Agent by writing insert queries for all the tables with conditions that no rows will be inserted which is already in SQL. note that this job is taking only 1 min to execute.
But in this way our SQL Server getting hanged and it giving problems to other application running in the SQL SERVER.
So i m requesting all of you that what is the best way to insert huge amount of data on the real time basis.
Thanx in Advance.1) Create Linked server
2) insert data using openquery and set job in sql agent
3) run job after 15 minutes -
Inserting data from Oracle to SQL Server 2008
Hi All,
I am using oracle 9.2.0.7 and SQL server 2008 in windows server 2003 operating system.
My requirment is like below.
1) I would liek to insert data from the Oracle database to SQL Server.
For the above requirement we have created the ODBC, then configure the listener file, tns file, and created the db link. This part is working fine as I am able to select the data from the SQL Server.
But when I am inserting the record from the oracle database to the SQL Server I am getting the error, (ORA-00904) Here oracle can not identified the column name.
My insert statement is like below.
insert into test@SQLTEST (name, fullname)
values ('Oracle', 'Oracle server data');
Test is the SQL server table name and sqltest is the db link name.
If I am select the data
select * from test@SQLTEST from Oralce I am getting the data properly.
Thanks,
SUN

Pulling data from oracle into sql server 2005
hi,
these days i am working on sql server 2005 on windows server 2008 64 bit.
and oracle 10g on 32 bit unix.
my problem is that when i am pulling data from oracle into sql server it shows me about *500-700 entries less*.
why this is happening? is it because 32 bit to 64bit? or is it because of different os?Akki,
are you using snapshot or replication from MSSQL? I am doing the same thing, hope to share your experience.
I am using import/export from MGT studio and pull some data from Oracle database, I am working on how to update the changes on these tables pulled from Oracle.

Migrating data from oracle to sql server
I have two databases(Oracle and Sql Server) in my company.
I want to migrate some data on daily basis from Oracle to Sql Server.
what are the best methodologies used to perform this task?
Can we schedule this task on daily basis?
please help me guysSalma,
First and foremost, you need to understand that there are architectural difference between Oracle and SQL Server (with the major one being the difference between Oracle's PL/SQL and Microsoft's Transact-SQL) thus, it will not be an easy task to migrate data from Oracle Database to SQL Server. As far as the use of tools is concerned, you can utilize the following tools (third party tools not recommended) to achieve this:
Microsoft SQL Server Migration Assistant (Oracle to SQL)
http://www.microsoft.com/sqlserver/2005/en/us/migration-oracle.aspx
Oracle SQL Developer Migration Workbench (SQL to Oracle)
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
But before proceeding with anything, I would recommend you to read through the following post as it lists down the primary compatibility resources and migration guidelines:
Migrating from Oracle to SQL Server

Hope this helps.

Error while converting schema from oracle to SQL server
Hello,
I am getting following error while converting schema from oracle to SQL server using SSMA.
I get Errors 1-3 while migrating procedures and error 4 while migrating a table.
1- O2SS0050: Conversion of identifier 'SYSDATE' is not supported.
2- O2SS0050: Conversion of identifier 'to_date(VARCHAR2, CHAR)' is not supported.
3- O2SS0050: Conversion of identifier 'regexp_replace(VARCHAR2, CHAR)' is not supported.
4- O2SS0486: <Primary key name> constraint is disabled in Oracle and cannot be converted because SQL Server does not support disabling of primary or unique constraint.
Please suggest.
Thanks.The exact statement in oracle side which causing this error (O2SS0050:
Conversion of identifier 'to_date(VARCHAR2, CHAR)' is not supported.) is below:
dStartDate:= to_date(sStartDate,'MON-YYYY');
Statement causing error O2SS0050:
Conversion of identifier 'regexp_replace(VARCHAR2, CHAR)' is not supported is below.
nCount2:= length(regexp_replace(sDataRow,'[^,]'));
So there is no statement which is using to_date(VARCHAR2,
CHAR) and regexp_replace(VARCHAR2, CHAR) in as such. 'MON-YYYY' and '[^,]'
are CHAR values hence SSMA is unable to convert it from varchar2 to char.
Regarding SYSDATE issue, you mean to put below code in target(SQL) side in SSMA ?
dDate date := sysdate;
Thanks. -

whether it will support Hetrogeneous Services?
How to know whether a database supports HS or not?

Creating Database Link from Oracle to SQL Server
I am trying to create a database link from Oracle to SQL Server, and the documentation is about as clear as mud to me. Can anyone send me clear instructions on exactly what I need to do? What needs to be in tnsnames.ora and listener.ora files? Is there anything other than those two files that needs to be set up? Do I set up an ODBC connection? Anything else? I want to execute queries against a SQL Server database and load data into Oracle database.
Thanks so much,
SusanThese are the instructions from an old document I created. The steps are same for SQL Server and Sybase. Hope it helps.
The 9i Transparent Gateway Software is in Oracle Software CD -> oracle9i database -> Custom -> Oracle Transparent Gateways
The gateway can be installed on the same machine as the Oracle database or
on the Sybase server or on a third machine as a stand-alone.
We have installed the gateway software in one of oracle database
servers in a separate oracle home.
These are the steps involved in configuring a gateway to a Sybase database
1. Install Sybase client and Gateway software on the Gateway Server
2. Configure <initsidfile> in the Gateway Server's <gatewayhome>
/u00/app/oracle/product/9.2.0/tg4sybs/admin/init<gatewaysid>.ora
Sybase server and database information is required for this step.
eg: HS_FDS_CONNECT_INFO=USTRUD01.uwd
3. Add an entry in listener.ora in <listnenerhome>
(/u00/app/oracle/product/9.0.1/network/admin/listener.ora) for the <gatewaysid>
4. Edit the tnsnames file (/u00/app/oracle/product/9.0.1/network/admin/tnsnames.ora)
to add an entry <tnsalias> for the <gatewaysid>
5. Create a database link to the Sybase database in the oracle database.
The steps for creating the database link are
a. create a login oracle_tgw in the sybase server
b. add the user to the sybase database with the necessary privilege on the tables
c. create the database link in the required oracle database using the command
"create public database link <dblinkname> connect to oracle_tgw identified by password using 'tnsalias'; "
6. Restart the gateway listener. -
How to insert Data from a function on server A into a table on Server B.
Hi,
I have a function which is like this
DECLARE @oldmax bigint, @newmax bigint
SELECT @oldmax = max(exportTimestamp) FROM EXPORT_TIMESTAMPS
IF @oldmax IS NULL
SET @oldmax = 0
SELECT * FROM ServerA.TableA.fnExportTrafficTS(@oldmax) ORDER BY storeID, TrafDate
SELECT @newmax = max(timestamp) FROM TRAFFIC t
IF @newmax > @oldmax
INSERT INTO EXPORT_TIMESTAMPS
VALUES(@newmax, GETDATE())
And now i need to insert the data coming out of this function into ServerB Table B
And the column names and everything coming out of the function is the same columns in Table B.So, no need to worry there.
I have never worked with inserting data from function through linked server.
Can someone please help me with this?
Thanks,
SujithWell, first of all, your table structure doesn't match the structure of returned table by your table-valued function.
This is what table valued function returns:
[storeID] varchar(32) default('noRefID'),
[TrafDate] [datetime] default(NULL),
[QtyTraffic] [float] default(0)
And this is what your table structure is:
[tUTL_JobLogging_Key] [int] NOT NULL,
[StoreId] [varchar](10) NULL,
[TrafDate] [datetime] NULL,
[Visits] [numeric](8, 2) NULL
Apart from different size for the StoreID and using float vs. numeric and different name for the last column, there is one extra column in your table.
So, this is the first problem you need to correct.
Also, please post how exactly you're calling your procedure? E.g. the procedure has 2 parameters, but the values of them are not used as you're calculating them in the code. So, I assume they should not be parameters for the procedure.

Creation of database link from oracle to sql server 2000
Hi
I need to create a database link from oracle to sql server 2000.Assuming your Oracle database is running on Windows, you can set up a database link using ODBC using Heterogeneous Services and Generic Connectivity, but there are some functional limitations (i.e. no two-phase commits). If you can live with those limitations but aren't on Windows, you can generally purchase an ODBC driver for your operating system that will connect to SQL Server through someone like DataDirect and still use Generic Connectivity. If you cannot live with those limitations, you can purchase one of Oracle's Transparent Gateway products (though this can get somewhat pricey).
What version of Oracle are you on?
What operating system(s) are you using?
What are you going to use the database link for?
