From SQL Server to Oracle 10g

Hi!!
My IT staff have been using SQL Server for quite a time and we have set up all our procedures under this platform, for example, our initial concern in this phase of the migration is: Under SQL Server we use templates that we use to import data into our tables in SQL Server DB, after uploading that data, we run some stored procedures and finally a view.
Is there any thing similar to a template under Oracle 10g?
I have been reading about the tools that 10g offers for data upload/download, but what about data files that doesn't have any field separator? All my fields have the same number of characters, that's why I use templates to import data on SQL Server.
Any ideas?
Best Regards,

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?

Reading milliseconds from Sql server into oracle 10g

Hi,
We have a very time sensitive pressing requirements to be addressed immediately.
We need to read the date time column from sql server 2008 into oracle 10g.
We have a dblink established between the two servers and have tried to use sql server and sql native client 10 driver to read the dates from sql into oracle.This we are able to do very successfully.
The issue is in reading milliseconds stored in sql server.The millisecond part comes in as 00000 from sqlserver to oracle.These milliseconds are needed to identlfy the unique records.
For instance
SQL SERVER Oracle
source_id source id
01/01/2012 6:30:35:456 01/01/2012 6:30:35:000000.
Im issuing my query through Toad via Oracle to remote sql server using a dblink which connects using HS ODBC connection to sql server 2008(remote).
We have no control over sql server Db as this is remote third party DB.We just have select access to their tables to bring into our own oracle DB.
Any insight or help will be much appreciated.

Hi,
Could you please send the following information -
- what version of HSODBC are you using ? Is it a 10.2 version ?
- what is the SQL*Server datatype of the column you are reading ?
- from Oracle could you issue -
describe sql_server_table@hsodbc
- what is the Oracle datatype shown for the column ?
Could you also run your tests using SQLPLUS instead of TOAD ? We don't support TOAD and need to know if the problem also happens when using SQLPLUS, to avoid it being a TOAD problem.
Also, 10.2 HSODBC is now desupported and you should be using the 11g Database Gateway for ODBC (DG4ODBC) which is a direct replacement for HSODBC. To use DG4ODBC your RDBMS needs to be at 10.2.0.4 or higher and DG4ODBC should be installed in a completely separate ORACLE_HOME from the existing 10.2 install.

How to import from sql server to oracle 10g

Hi,
I have given some file with no extention and the client told me that
it has two tables in it emp and dept. which he extracted from sql server.
Now I have the file with me.
I have a local oracle database .
Is it poosible to load that file into the oracle 10g database.
If possible please send me the details. If not please tell me the details reqd to do the things.
Thanks in Advance

Well, what format is the file in? If it is a text file you should be able to use SQL*Loader.
Can you view the file using (for example) Wordpad?
Or from the command line (ie in a DOS box) just say
TYPE myfileThen post the format for a few lines here, between and (use square brackets instead of curly)

Hello:
You could consider using Oracle Heterogeneous Services to do this. If your Oracle database is on a Windows platform the link below shows you how to make a connection to SqlServer from an Oracle database.

Migration from SQL server to Oracle 10g

Hi, I am new here,
I would like to ask how to use SQL developer MWB to migration SQL Server to Oracle?
I have go through the doc(s) like: getting start, user's guild, etc. and have following problems
(1), where should the SQL developer installed? in SQL Server side? Oracle side? or any PC with connection to the databases?
(2), do I need to get some plug-in(s) for MWB to work? If yes, which plug-in do I need and where are they?
Thank you very much.

Migrate Data action hanging migrating from sql server to Oracle 10g

Hi,
I am currently migrating a SQL Server 2005 db to Oracle 10g using SQL Developer 1.2.1. I have created the migration repository, captured the SQL Server db objects, and created the target schema. There are about 109 tables captured. During Data migration, however, the data move hangs. I have run the data move a couple of times now and it does not hang while migrating any particular table, but seems to be more to do with the length of time it is taking to migrate. Could this be an issue with SQL Server connections being lost? The SQL Server db is quite large. Row counts of 100k plus.

Probably. There is an offline option for migrating data under the migration menu. Generate Scripts for the data move using the appropriate converted model and u can export the data to bcp export files and load it with teh generated SQL Loader scripts.

One way replication from MS sql server to Oracle 10g

Hi,
We are using Sql server 2005 windows 2003 32 bit and Oracle 10g 10.2.0.3 on linux 64 bit
Is it possible to replcate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit?
If yes then what are the steps.
It will be one way replication from sql server to oracle.
Which option is best sql server dts or Oracle Stream replication to replicate table data?
Regards,

If you want to push data from SqlServer, then ODBC, Linked tables, DTS etc.
If you want to pull data from Oracle, then Heterogenous Services / Gateway.

Migration from MS SQL Server to Oracle 10g

Hi,
In our application, we are planning to refresh data every one hour from MS SQL Server to Oracle 10g. Can anyone tell me what approach can be followed?
Thanks & Regards,
Faizal MK

Hello,
migrations can be done with the Migration Workbench that is included in the SQL Developer: http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
But your question sounds more like a replication of data than a migration. Please read as a starter the following note in My Oracle Support (former Metalink):
Note 283700.1: How to replicate Data between Oracle and a Foreign Datasource
That note describes ways for the replication in both directions. Please let me know whether this is helpful for you.

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.

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

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

Related to migration of db from sql server to oracle 11 g

We're trying to migrate a Sql server managment studio database to Oracle 11g using SQL Developer 4.0. We can successfully connect to both Sql server managment studion 8.0 and Oracle 11g using the tool, as well as click through the Migration Wizard and start the migration.
This opens the Database Migration dialog box, which indicates the capture process starts normally. we get the following error:
ora :01440 : can not insert null into migrlog (id column) ,
\and then after some time , i get an error that migration failed
i am not getting the reason,I thing it may be due to reason that , I have table's column in my source db with more than 30 character.
If i am migrating one by one table . then it is not giving any error, and identifier name is getting shrink in 30 character. but i am not getting the view , stored procedure , indexes , and others
then what is the solution for that, somebody pls suggest any help?????????????

Pl do not post duplicates - related to migration of db from sql server to oracle 11 g
Continue the discussion in your original thread
The error message is explicitly clear
ora :01440 : can not insert null into migrlog (id column)
Your process is trying to insert a NULL value into the ID column, which presumably cannot be NULL

Any idea what is the problem ?

I'm having the same error message...But I'm connecting to a Oracle 8i DB......
I think this has to do with SP4 for SQL....I will test this tonight....

Migration from SQL Server to Oracle 8i

Hi,
what are the general issues to be considered when migrating a database from SQL server to Oracle 8i.
Is it documented on the web/ or any publication
Samit

What we did was to create the schema using migration work bench and then transfer the data using data junction
The main issues that you have to handle are
1) Data type issue, here problem comes converting chars to varchars as chars are padded and may not work in indexes, so you have to trim the afterwards, and if you have any image type data types in Sqlserver, you can use either lobs or long raw, it again depends upon your application, if you uses lobs you may have to recode your application
2) Sql statements, Oracle cannot understand Sqlserver sql statements, so you have to convert them all. Sqlserver allows two outerjoins to a table, Oracle does not, so you have to modify your functionality
3) Connections to the database. if you are using ODBC then use Oracle ODBC drivers and the latest ones, otherwise you may encounter memory leaks.
These are from the top of my head, if you have any specific problem I may be able to help.
Good luck

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.
