ETL from SQL server 7 to Oracle 8i

I am working on a project which needs constant (daily or weekly) data extraction from SQL server db to Oracle 8i db. The data come from 11 tables, and some logic needs to apply before extraction to make sure only certain set of data is extracted.
Here are a few options that we can think of:
1. Using Oracle Migration Work Bench
2. Using Access as middle layer to do SQLServer--Access--Oracle
3. Write TSQL at SQLServer 7 and push data to Oracle (but our team don't have TSQL skills)
Do anyone has any insight into this issue? I would really appreciate if you can help out!

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

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.

Planning db from SQL server to Oracle

Hi Friends
We are planning to upgrade our Hyperion Environment from 9.3.3 to 11.1.2.2. and we are going from SQL server to Oracle as our RDBMS.
If we are changing DBMS, do we have to rebuild total application or is there any easy method to migrate from sql server to Oracle
Please suggest
Thanks

Thank you so much John
Just to make sure i got it correct
1. Export from 9.3.3 to 11.1.2.2 using LCM
2. Delete the planning application
3. Update oracle data source on 11 point to Oracle
4.Again use LCM to export planning app from 9.3.3 to 11.1.2.2
Please suggest if i am wrong
Thanks
No you would upgrade the planning application using the upgrade wizard in 11.1.2.2, once the application has been upgrade you can use LCM to export the full application, then delete, re-point data source, import using LCM.
Cheers

Migration of table from sql server to oracle

Hi,
I had to export few tables from SQL Server to Oracle. After the migration, I am checking to see all the tables in Oracle that have been migrated from Sql Server. I am executing select * from tab; and am seeing all the the tables (including those have been exported) from the output list of tables. However, when I am doing a select * from x; where x is one of the few tables that have been migrated, it says table or view does not exist. This is the problem with all other migrated tables. Any help is appreciated in advance. Thanks.

Try select * from "x"

Migrating from SQL Server to Oracle 8i

Hi all :),
I am trying to migrate from SQL Server to Oracle 9i.
I am using the Migration Workbench.
Everything goes fine during Capturing phase, but while
creating Oracle model the Workbench just hangs at
"Mapping Tablespaces" for over three hours.
(not exactly hangs in the sense that it responds to mouse
events and I can abort the ongoing activity ...)
What should I do ? Should I let it go on and see what
happens.
I follow each and every step as mentioned in the
documentation ... but obviously I am doing something
wrong. Any pointers ???
However ... if I try to migrate to Personal Oracle 8 ...
the migration goes fine from start to end ... just that
the SQL Server triggers aren't successfully migrated.

You may want to start by downloading the Oracle Migration Workbench. That generally does a reasonable job in moving the tables, stored procedures, etc. from SQL Server to Oracle. If your VB code is database agnostic, it should continue to work without any more intervention. Realistically, however, you'll rpobably have to at least tweak a few things that don't work the same way in the old ODBC/ OLE DB provider and the new one.
The hard part of migrations like this is that you may need to revisit some of your architectural decisions if you want Oracle to perform well. There are plenty of things that one does in SQL Server (i.e. frequent commits) to improve performance that have the opposite affect in Oracle. Identifying and fixing these sorts of things tends to be the largest part of a migration like this. Unfortunately, I don't know of a resource that talks addresses all the possible gotchas here.

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?

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

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.

Srinivas

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,
