Replication SQL Server 7 Database to Oracle 9i

Hi -
I'm new to Database Replication, what are the steps for database replication from a MS SQL Server 7 database to Oracle 9i? Eventually this SQL Server Database will be going to SQL Server 2000 are the steps different, if so what are they?
Thanks
Much

I do not what you mean with Replicate between SQL Server and Oracle. Perhaps you mean migrate from SQL Server to Oracle or to stablish a transparent gateway.
I am going to give you this reference:

Migrating SQL Server database to Oracle 8i - any known issues

Hi,
I am in the process of migrating SQL Server database to Oracle 8i for testing purpose.
When I do migrate SQL Server database to Oracle 8i, am I doing any harm to the exiting
SQL Server database? Would the users be able to use SQL Server database as usual?? Are
there any known issues in this regard?
Please reply.
Thanks.
Ramesh

Ramesh Hi Ramesh!
The Migration Workbench does not make any modifications to the SQL Server database. It only reads information from it. Your users should be able to use the SQL Server database as usual.
Please note however that if you migrate the data over to Oracle using the Migration Workbench and your users continue to enter/update data in the exiting SQL Server database then you may need to move all that data over again in order to have the most up to date data in the Oracle database.
thanks

Murray,
Apologies for referring to the 1.5 documentation but the 2.1 documentation still has the same information about creating a user to hold the repository.
You initially reported 2 problems -
1. Locating source plugin...failed
2. Checking multi-schema privileges...Privilege 'CREATE ROLE" is not granted with admin option.
For the first error have you installed the necessary JDBC driver ? I have just installed SQL*Developer 2.1 on a new laptop and could successfully connect following the documentation steps -
Oracle® SQL Developer
User’s Guide
Release 2.1
2.5.2 Before Migrating From Microsoft SQL Server or Sybase Adaptive Server
To configure a Microsoft SQL Server or Sybase Adaptive Server database for
migration:
1. Ensure that the source database is accessible by the Microsoft SQL Server or
Sybase Adaptive Server user that is used by SQL Developer for the source
connection. This user must be able to see any objects to be captured in the
Microsoft SQL Server or Sybase Adaptive Server database; objects that the user
cannot see are not captured. For example, if the user can execute a stored
procedure but does not have sufficient privileges to see the source code, the stored
procedure cannot be captured.
2. Ensure that you can connect to the Microsoft SQL Server or Sybase Adaptive
Server database from the system where you have installed SQL Developer.
3. Ensure that you have downloaded the JTDS JDBC driver from
http://jtds.sourceforge.net/.
4. In SQL Developer, if you have not already installed the JTDS driver using Check
for Updates (on the Help menu), do the following:
a. Click Tools, then Preferences, then Database, then Third Party JDBC Drivers.
b. Click Add Entry.
c. Select the jar file for the JTDS driver you downloaded from
http://jtds.sourceforge.net/.
d. Click OK.
========
The second error is again documented in the 2.1 documentation -
5.99 Privilege Warning for Migration
This dialog box is displayed if you click Verify in the Quick Migrate box and the
database user for the connection does not have all privileges necessary for a
multischema migration. For multischema migrations, this user must granted the
RESOURCE role with the ADMIN option; and this user must also be granted the
CREATE ROLE, CREATE USER, and ALTER ANY TRIGGER privileges, all with the
ADMIN option.
If you are performing a single-schema migration, you can ignore this warning.
=====
Which errors are you now seeing and which user was used to hold the repository ?
If you are using GRAINTEST for the repository then create it using this syntax -
CREATE USER GRAINTEST IDENTIFIED BY password <=== change password as necessary
DEFAULT TABLESPACE users TEMPORARY TABLESPACE temp; <=== change tablespaces as necessary
GRANT CONNECT, RESOURCE, CREATE VIEW, CREATE PUBLIC SYNONYM TO
GRAINTEST WITH ADMIN OPTION;
GRANT ALTER ANY ROLE, ALTER ANY SEQUENCE, ALTER ANY TABLE, ALTER TABLESPACE,
ALTER ANY TRIGGER, COMMENT ANY TABLE, CREATE ANY SEQUENCE, CREATE ANY TABLE,
CREATE ANY TRIGGER, CREATE ROLE, CREATE TABLESPACE, CREATE USER, DROP ANY
SEQUENCE, DROP ANY TABLE, DROP ANY TRIGGER, DROP TABLESPACE, DROP USER, DROP ANY
ROLE, GRANT ANY ROLE, INSERT ANY TABLE, SELECT ANY TABLE, UPDATE ANY TABLE TO
GRAINTEST with admin option ;
then when making the migration make sure the Oracle connection is to this user.
Please update the thread with the errors you get after following these steps.
Regards,
Mike

My Experiences re: Migrating SQL Server Database to Oracle

I am using SQL Developer EA4 for thsi conversion, best attempt yet.
I had numerous problems with this conversion.
1. The wizard asked me to specify the new Oracle database; instead it just ignored this information and created an Oracle database similarly named as the SQL Server database. I also noticed a file name "Migration.out" was produced; it contained errors such as:
Error starting at line 3 in command:
CREATE USER Emulation IDENTIFIED BY Emulation DEFAULT TABLESPACE USERS TEMPORARY TABLESPACE TEMP
Error at Command Line:3 Column:36
Error report:
SQL Error: ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges" and
Error starting at line 4 in command:
GRANT CREATE SESSION, RESOURCE, CREATE VIEW, CREATE MATERIALIZED VIEW, CREATE SYNONYM,CREATE PUBLIC SYNONYM TO Emulation
Error report:
SQL Error: ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges" and
Error starting at line 7 in command:
CREATE USER dbo_COREv13 IDENTIFIED BY dbo_COREv13 DEFAULT TABLESPACE USERS TEMPORARY TABLESPACE TEMP
Error at Command Line:7 Column:38
Error report:
SQL Error: ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges" and
Error starting at line 8 in command:
GRANT CREATE SESSION, RESOURCE, CREATE VIEW, CREATE MATERIALIZED VIEW, CREATE SYNONYM TO dbo_COREv13
Error report:
SQL Error: ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges".
I followed all of the steps listed in the "Help" section re: Migrations but still ended up with these errors.
2. My schema consists of 1000+ tables; approximately 10 tables were NOT created. When I copied the SQL from Migration.sql making NO changes and pasted it into the new Oracle database it created without issues.
3. While the conversion is taking place, different objects (constraints, indexes, foreign keys, etc) are shown to be copied; their appears to be ordering of these items. Shouln't a dependancy tree be established, and object converted based on this?
4. Several tables, in my case about 250 tables did NOT get any data copied across. No reasons given.
5. A log of all activities should be produced for review and completeness.
6. I tried to use the "Migrate select tables" option but met with no success. Apparently, it makes an assumption that both the "source" and "target" databases wil be of the same type (ie both SQL Server or both Oracle); this does not make any sense to me since the point of the exercise is to migrate data from one database vendor to another. Obviously, different database vendors use differing datatypes for similar data (ie dates).
7. I noticed in the "Migration" sql that the "Connect" statements are not correct; they were missing the "instance name" portion.
8. Also, when I looked in the "MIGRATION" sql, I could not find any entries for the last step of the conversion - the movement of data from SQL Server to Oracle. Is this intentional or an oversight.
I dont want to appear negative on this Migration; I have used SQL Developer since it inception; in my opinion this is the best attempt to date.
Murray Sobol

Hi Murray,
Thanks for this feedback.
There is a lot of questions here, I think some of it boils down to misunderstandings, which we should clarify in the doc.
Hopefully Ill get a video of a migration online soon as well.
But here is a brief break down.
*1.*
"The wizard asked me to specify the new Oracle database; instead it just ignored this information and created an Oracle database similarly named as the SQL Server database."
So this relates to Step 7 of the Migration Wizard. Where you can select the target connection.
SQL Developer doesn't ignore the Target Connection you selected, It just uses it to connect to the target database , not the target schema.
SQL Developer generates a new target schema for the migrated objects. It standard approach is not to generate objects directly into an existing Schema.
The Target Connection is used to create all the migrated objects (including new Oracle Schemas) in your target oracle database. So you should choose an Oracle Target Connection which has enough privileges to create new Schemas and Objects.
But as you have found, it doesn't generate the migrate objects , like tables, ... , directly into your chosen Target Connection.
From the errors you encountered it doesn't sound like the Target Connection (and the underling Oracle Schema) doesn't have the privileges to create other Schemas.
If you use something like a connection to the SYSTEM schema on your target database, it should run OK.
It wont create any objects in SYSTEM, rather it will use SYSTEM privileges to create a new schema (ex: dbo_Northwind) and populate it.
You don't have to use SYSTEM, but you do need a schema with enough privileges to create other schemas.
That is the straight forward way. But if you really need to generate into an existing schema the following steps can be taken.
a)rename the schema under the Converted Database Objects
b)Right click "Converted Databases Objects" and choose generate. it will kick off the Migration Wizard in the correct place
*2.*
My schema consists of 1000+ tables; approximately 10 tables were NOT created. When I copied the SQL from Migration.sql making NO changes and pasted it into the new Oracle database it created without issues.
When you say Migration.sql , is the entire generation file , which can be found in your <outputspecified>/generated/<projectname.modelname>.sql ?
When your say "pasted it into the new Oracle database" , are you running it in SQL Developers SQL Worksheet using the Target Connection.
Basically your migration is all out of shape once the target Schemas are not created. So the above issues (insufficient privileges) has to be resolved first.
Please post back if it is still an issue.
*3.*
While the conversion is taking place, different objects (constraints, indexes, foreign keys, etc) are shown to be copied; their appears to be ordering of these items. Shouln't a dependancy tree be established, and object converted based on this?
Objects are converted in a particular order and their dependencies are persisted so that they can be generated in the correct order.
Are you seeing an issue?
*4.*
Several tables, in my case about 250 tables did NOT get any data copied across. No reasons given.
I'm surprised any tables were populated with data due to the target schema not being created.
The online data move is pretty simple and it does not report or recover very well from issues.
If you are having difficulties once item 1. is resolved, please post an example of the source table and I will give it a go.
For better control of the data move with much more powerful tweaking, error handling, reporting and performance try the offline data move.
SQL Developer can created a suite of scripts which use SQL Servers BCP tool to dump out the data to dat files, and Oracle SQL*Loader tool to insert the data in the dat file into Oracle.
*5.*
A log of all activities should be produced for review and completeness.
The output/generated/<projectname.modelname>.out provides the output of running the generation script.
The migration reports http://dermotoneill.blogspot.com/2010/11/migration-reports-30.html outline what happens during the migration.
Apart from online data move issues, is there any other data missing?
*6.*
I tried to use the "Migrate select tables" option but met with no success. Apparently, it makes an assumption that both the "source" and "target" databases wil be of the same type (ie both SQL Server or both Oracle); this does not make any sense to me since the point of the exercise is to migrate data from one database vendor to another. Obviously, different database vendors use differing datatypes for similar data (ie dates).
Do you mean "Copy To Oracle" ? This option is intended to migrate tables from non Oracle databases like SQL Server to Oracle.
Can you give more details on what issue you are seeing.
*7.*
I noticed in the "Migration" sql that the "Connect" statements are not correct; they were missing the "instance name" portion.
The generation script is meant to be run using SQL Developers SQL Worksheet. I think you only get this "instance name" issue if running from SQL*Plus.
Can you confirm
8. Also, when I looked in the "MIGRATION" sql, I could not find any entries for the last step of the conversion - the movement of data from SQL Server to Oracle. Is this intentional or an oversight.
The online data move is performed separately from creating the objects. It is not script based, it uses JDBC to pump the data from the source database to the target database.
In summary , I would
a) Create a connection to your Target database using your SYSTEM schema
b) Right click on your "Converted Database Objects" and choose "Generate Target"
c) Choose your new "System" connection as the Target Connection
d) Follow the Migration Wizard to the end.
You will end up with a new target Schema and the migrated objects in it.
Check the .out file to see the errors
and the migration reports http://dermotoneill.blogspot.com/2010/11/migration-reports-30.html

How to import sql server database into oracle

Hi,
i have a backup of database(complete) from sql server, Is there any way to import that backup database into oracle environment.
Please let me know the process
Thanks
Naren$

No. You cannot simply import binary data files from a 3rd party database directly into Oracle.
You can use bcp on SQL-Server to unload the data to CSV and then use Oracle's SQL*Loader to load it.
You can run a SQL-Server database instance and an Oracle database instance, and use a heterogeneous database link from Oracle (working via ODBC) to connect to SQL-Server - and use SQL statements to pull object definitions and data from SQL-Server into Oracle.

Convert Sql server database into oracle

hi friends
i have a very smal database of sql server containing 8 tables
i want to convert my databse into oracle plz tell me in detail coz i dont know any thing about it.
plz help me
take care
bye

If the amount of data is small, you might look into Microsoft Data Transformation Services (DTS), which comes with SQL Server. This provides an easy to use GUI for mapping data between two sources.
A few warnings:
- If you let DTS create your Oracle tables, beware that that table / column names may be created as case-sensitive and data types may not be what you expect
- If you are transferring a lot of data (e.g. millions of rows), performance will be terrible.

How to replicate a SQL Server database to Oracle?

I want to create an Oracle database. I have an existing SQL database. I have created an sql file of the SQL database. Should I just run this file from the sql prompt? Do I need to create a service id for the new database and then run the sql file? Also please can anyone tell me how different is this task in Oracle 8i and Personal Oracle? I have not worked on Personal Oracle before but I have worked extensively on Oracle 8i. What has to be done to create a database in Personal Oracle? Thanks a lot.

Hi,
Take a look at the main [ SQL Developer page on OTN|http://www.oracle.com/technology/products/database/sql_developer/index.html]. There is a link you should find useful, it's the Getting Started link under the Migration section. This explains how to download and setup the drivers you need to correct to non-Oracle databases. There are also links to online demonstrations on how to create connections to these databases. See how you go with that material.
It should help.

SQL Server database (read-only mode) in Oracle SQL Developer

Hello,
I connected SQL server database with Oracle SQL Developer 3.2.10.09, everything looks good except i can only browse data, i cannot change data in tables cannot insert new or delete rows. Query is also disabled (i got message: Query Builder is not supported for this connection type.) I used Third Party JDBC Drivers - jtds-1.2.6.jar as my connection to SQL server. Is there a way to change data in tables?
Thank you.

AFAIK editing table data in the grid is only possible with an Oracle database. On MS SQL you'll have to use update statements in the worksheet.
Hope that helps,

The hardware can be changed if needed. Can you please suggest the best approach ?
Thanks,

Hi Naveen,
We would like to migrate our Siebel database from Sql Server 2005 to Oracle 11g RAC. Can you suggest the best way to do that ?You will need much more which suggestions.
You will need a Siebel professional which has done this type of migration. Migrating the Database is not a task so hard, after migrating your environment should be functional and healthy it is usually the task problematic.
The hardware can be changed if needed. Can you please suggest the best approach ?We can recommend the minimum recommended, but this documentation already does, you need to do a analysis on your environment and ask a vendor Siebel tell the which is recommended for you and how to find the best "number" for you, in your case is very hard because everything changes.

Migrating DB from SQL Server (Windows) to Oracle (Unix)

I wish to migrate a SQL Server 2000 database on a Windows environment to an Oracle database on a Unix environment.
Are there any issues with using the Oracle Migration Workbench to migrate a SQL Server database to Oracle between different operating systems?
Thanks in advance.

Hi!
After trying to migrate only a copule of schemas from sqlserver, my solution appeared by itself. It seems that something goes wrong if you migrate only selected users, so I build up a test instance in windows, made the workbench repository on it, and ran a full migration from all the users to this test environment.
After this it was nice, cause I made an exp from the squema I wanted and imported it on production environment.
PD: Migration logs only raised java related problems. I got quite crazy realizing what jdbc version I had, but it wasn't the problem.
By the way, if you try to run sqlloader scripts, be careful with language issues, cause I had to reverse data loading because incorrect typos or so.
Thanks a lot for your help.

Converting Access application after migrating SQL Server database

I have used migration workbench to migrate an access database and application. I now have sql server databases with access applications that need to be migrated. How can I convert the access applications that currently use sql server as a database? I don't see that migration workbench considers this combination.

If you have and Access/SQL Server combination. then download the SQL server plugin appropriate to your version of SQL server. Go ahead and migrate the SQL Server database to Oracle. Once this is done, then update your access application so your link tables point to your newly migrated Oracle database.
