Migrate SQL Server 7.0 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
The Migration Workbench copys the information it requires from the source database and stores it in the Migration Workbench Repository, which is separate from the Source database. So, to answer your question, yes, the users can continue to use the SQL Server database. The data move may cause some system performance degradation. It may also be an idea to replicate the SQL Server database, in case any complication should arise.
Hope this helps

Migrating SQL Server 7.0 to Oracle 8i in Different Operating Systems
I am migrating SQL Server 7.0 Databases on NT to Oracle 8i on Sun 2.6. Is there is any other way other then Migration Workbench.
If Mig Workbench is OK. What are the steps to do Migration.
nullHi,
You can perform this action with the Oracle Migration Workbench. Just install the Workbench on the same machine as your SQL Server database.
You can then configure the workbench to point to the oracle database on your Sun machine.
You can use the Oracle database on your Sun machine for both your destination database (the database to which you migrate your SQL Server schema and data) and workbench repository.
In order to do this you will need to configure a tnsnames.ora entry. The tool that will do this configuration for you should be started up at the end of the workbench installation. It is a fairly straightfoward process.
You then need to create a user in your oracle database that will store the workbench repository.
Once you have comleted these steps you will be able to migrate SQL Server on NT to Oracle on Sun.
It is exactly the same process as migrating to Oracle on NT except you are pointing the Workbench to Oracle on a Sun box.

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

Migration SQL Server 6.5 to Oracle 8.0.5
I am migrating from SQL Server 6.5 to Oracle 8.0.5 using
migration Workbench Ver. 1.2.2. The stored procedures are not
migrated properly where temporary tables are used to store the
intermediate results of a query on SQL Server 6.5 side. I want
to look at the coding to create a temporary table with sessionid
as part of table to make it unique for the session and the user
on the oracle side using DBMS_SQL package. Any body can give me
the coding ?

I have used the correct option and the Migration Workbench is
not creating the DDL statements correctly for the creation of
table. Whatever may be the problem I want use DBMS_SQL for
creation of unique table names with session id as part of the
table name. I need a sample script to use session id as part of
table name and to vary the name of the table dynamically in
DBMS_SQL. It is not accepting the variable name for table name
in create table statement.

Migrating SQL Server 6.5 to Oracle 8
Hi,
I am currently converting some stored procedures from SQL Server 6.5 to Oracle 8 (PL/SQL). I am having trouble converting some nested sql statements such as the following to work in Oracle.
Example :
SELECT antall=COUNT(*), ulest=(SELECT ulest=COUNT(*) FROM soknad s, annonse
a WHERE a.kundeid=13817 AND s.annonseid=a.id and lest != '1') FROM soknad s,
annonse a WHERE a.kundeid=13817 AND s.annonseid=a.id
The Select is first getting a count on the two tables for a particular id, the second field in the statement has a nested select which does a similar count but has a further condition on it.
It could be done using two SELECT statements like this -
SELECT COUNT(*) AS antall
FROM soknad s, annonse a
WHERE a.kundeid = 13817
AND s.annonseid = a.id
SELECT COUNT(*)
FROM soknad s, annonse a
WHERE a.kundeid=13817
AND s.annonseid=a.id
AND lest != '1'
which may be workable but I would like to keep it as similar to the original as much as possible.
Any ideas would be great!
Thanks,
BradI have since found out subqueries in the select list are not supported by Oracle.

Migration SQL Server 7.0 to Oracle 8i
Hi,
I am trying to migrate a SQL Server 7.0 database to Oracle 8i using the latest version of the Migration Workbench tool. The source model is normally generated (I see my tables and other objects) but nothing is generated in the Oracle Model... What would be an explanation for this issue and how could I fix it ?
Thanks in advance.
FabienLooks like the capture has gone OK but have you gone through the mapping phase?

Migrate sql server dump file to Oracle database on a network
I have a sql server dump file provided to me by DBA's. I have to migrate this dump file to Oracle database on a network. Please suggest me the steps to do this.

regardless of the tool/technique you use, those bits have to get from machine running sqlserver to the machine running Oracle. Either over the network (through the firewall) or via 'sneakernet.' What, exactly, are the firewall constraints?
If the export is a simple text file (character delimited fields? fixed length fields?) and only 100 records ... Migration Workbench may be overkill, perhaps a simple sqlldr job. But you still have to get the bits from 'there' to 'here'.
============================================================================
BTW, it would be really helpful if you would go to your profile and give yourself a recognizable name. It doesn't have to be your real name, just something that looks like a real name. Who says my name is really Ed Stevens? But at least when people see that on a message they have a recognizable identity. Unlike the system generated name of 'ed0f625b-6857-4956-9b66-da280b7cf3a2', which is like going to the pub with a bag over your head. -
Error migrating SQL Server 2000 database to Oracle.
Hi,
I am new in SQL Developer.
I read most of the help manuals available on the net.
I am able to create connections to both SQL Server and Oracle database.
I am also able to create the migration repository on the Oracle database.
SQL server connection - TestSQL
Oracle database connection - TestOracle
Migration Repository - Migration_Repository.
Here is the problem am facing:
When I start Migrate to Oracle wizard, by right clicking the TestSQL database, I followed all the required steps and enter the necessary information. -
It starts creating the project - say, TEST but after that it gave the following error:
Migration actions have failed. Check the migration report for more details. : ORA-01400: cannot insert null into ("MIGRATIONS"."MD_PROJECT_ID").
Please help.Thanks for your reply.
You are correct, there were some permission missing on the migration repository user.
I have given permissions and it worked fine.
but I can say that required permission mentioned in other posts and blogs on the Internet are not sufficient.
One has to provide more admin priviligies to this user. -

Migrating SQL server 6.5 to Oracle
Does anyone know if SQL seveloper 1.5.5 work with SQL Server 6.5? i have been trying set it up, but i get the following error every time when trying to connect to the 6.5 SQL Server:
Status: I/O Error: Stream 0 attempting to read when no request has been sent
BTW, i do not hav ethe option to upgrade the SQL Server at thi stime
Any help would be greatly appreciated.
Thanks in advanceHi Jacques,
Just to be clear.
SQL Server 6.5 is not supported by SQL Developer or the old OMWB.
The only supported version of SQL Server, is 7,2000 and 2005 which are supported by SQL Developer.
Having said that
The old OMWB can be downloaded here
http://www.oracle.com/technology/software/tech/migration/workbench/index.html
And the old (unsupported) SQL Server 6.5 plugin can be found here
http://download.oracle.com/otn/nt/omwb/101040/SQLServer6.jar

Migrating SQL Server SSIS package to Oracle
Dear All,
We are using Microsoft SQL server 2005 in our application, we have two separate Server instances where one instance synchronize data from other server table using SQL Server SSIS package. What can be the counterpart of this functionality in Oracle. I have looked into materialized views but in my case the target table will have more columns than the base table, and the query used to get data from base table will extract some values from one of the BLOB type column of base table and then populate target table multiple columns.
Kindly suggest me any solution.
Best Regards

Migrating SQL Server development skills to Oracle
Hi all,
I've been working with SQL Server in a development capacity for about 7 years now. I'm no specialist, but I'm comfortable in it and am conversant in SQL Server terminology. I need to pick up similar development skills in Oracle. I don't need to know a lot about DBA stuff, perhaps just a few considerations for performance tuning. I won't be "switching" to Oracle, but rather picking up those skills and working on both platforms for the forseeable future.
What I'm looking for is a book/white paper/website which gives me, as quickly as possible, a direct comparison between SQL Server and Oracle. Some of the things I might want to know are (in order):
- Syntax differences between T-SQL and PL-SQL
- T-SQL functions and equivalent Oracle/PL-SQL functions
- Connection and setup methods (for one, I believe everything in Oracle resides in schemas generally under a single database?)
- An overview of the reasons people would use Oracle rather than SQL Server
Can anyone recommend a book in this regard? Failing that, can anyone recommend a book on Oracle which is, hopefully, more on the concise side and includes a function reference?
