Portals DB migration SQL Server to Oracle?

Hello, Can EP6 running on Win2000/SQLserver be migrated to Oracle database. I searched OSS but couldnt find any reference (https://websmp108.sap-ag.de/nw-epmig). If possible, what would be the steps involved. Any help would appreciated

John,
It is not possible to change the DB vendor during migration, using the migration tools, but
after upgrading EP 5.0 to EP 6.0 NW2004s on SR1 we can use the heterogeneous system copy to go from
SQL 2000 to Oracle 10g?
No cross platform (operating system) migration. Is this during migration using the migration tools
only? Or even after the EP 6.0 NW2004s on SR1 we can now then do both a DB switch and a platform swicth
(i.e. Windows/MS SQL 2000 to Unix/Oracle 10g?
Thanks.
James

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.

Hi Chocobo,
I put together a Quick Guide myself

Migration from SQL Server to Oracle issue

Hi,
While trying to migrate SQL Server to Oracle via Standard Migration method, I got stuck at the point where it says.....
To perform online capture, right-click the connection name in the Connections navigator and select Capture database-type (for example, Capture MySQL, Capture Microsoft Access, Capture Microsoft SQL Server, or Capture Sybase Adaptive Server).
The problem is that, I do not see this menu Capture Microsoft SQL Server. Looks like this is a bug SQL Developer 3, which does not shows option for Capture on right clicking the non-oracle database connection. In earlier release of SQL Developer 2.1.1, I can see the option of Catture...
Thanks,
Gyan

Gyan,
You are correct. The online help screen says -
<<<
Online Capture
To perform an online capture of the source database, you can have the capture performed automatically as part of the Quick Migrate option, or you can have it performed as a separate operation by right-clicking the connection name in the Connections navigator and selecting Capture product-name (for example, Capture MySQL, Capture Microsoft Access, Capture Microsoft SQL Server, or Capture Sybase Adaptive Server).
>>>
but this option does not show up.
I did some testing and was able to make the capture by following these steps -
- right click on the SQL*Server database in the Connections panel
- choose 'Migrate to Oracle'
- follow the menus until you get to 'Capture' screen where you should have the SQL*Server database to be migrated in the 'Selected Databases' panel
- then choose 'Finish' from the options at bottom of the screen.
- you should then have the capture scripts in the directory chosen earlier in the process.

Mike

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

Your process is trying to insert a NULL value into the ID column, which presumably cannot be NULL

Migration from SQL server to Oracle

Hi,
Has anybody done migration from the SQL server to Oracle? If so, what manual method do you recommend? I'm a new college grad and I would like to get your expertise, if you have done this in the past.
Thanks in advance!
Sho

It is some time back, so I do not remember the specifics. Oracle gives Oracle Migration Workbench for free. You can use it to convert all SQL tables and procedures etc to oracle. It is not that difficult. If there are no stored procedures etc, you can just extract the DDL and create the tables with minor changes to the script. You might need bcp-sqlloader/trasparent gateway etc copy the data.

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

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.

Migrating SQL Server DB to Oracle DB - probably EASY answer

I completed the tutorial on migrating SQL Server DB to Oracle. When I try on my own database, it all migrated well except anything containing a datetime. When I run the oracle_ctl.bat file and view any of the log files, I see Record 1: Rejected - Error on table DBO_RIVERSIDEDB_NCWCD_TEST.TS6HOUR_TAIN, column DATE_TIME.
ORA-01843: not a valid month. Do I need to change the first line of the file set NLS_DATE_FORMAT=Mon dd YYYY HH:mi:ssAM ? In the .dat file created from the unload_script.bat, the data starts out 1275<EOFD>2007-05-11 00:00:00.000<EOFD>74.900000000000006<EOFD><EOFD><EORD>1275<EOFD>. So my questions is about the date_format - is that the same for all SQL Server databases or do I need to enter something based on MY database? I am definitely a newbie so this is probably a super easy question. Thanks so much for any help!

Hello,
There are two different date format in SQL Server.
1] DateTime : 2010-08-03 12:48:15.170
2] SmallDateTime: 2010-08-03 12:48:00
Both the date will be inserted in Oracle Date column.
Is there any automated way to generate datamove script to tackle these differences? I've around 200 tables to be migrated and there may be many such cases.
The issue with Oracle SQL Developer setting i.e. Tools >Preferences> (Under) Migration> Data Move Option, there are two masks we can specify, one for Date Mask and other for Timestamp. How can I set both of these for converting data into Date, not in timestamp.
Below is my .CTL file, none of below fields are timestamp, but since incoming data in in timestamp format, it is applying timestamp mask and eventually failing to insert data into table
load data
infile '[PARTSORDER].dat'
"str '<EORD>'"
into table admin.PARTSORDER
fields terminated by '<EOFD>'
trailing nullcols
ORDERID ,
GenDate "TO_TIMESTAMP(:GenDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",
Status "DECODE(:Status, CHR(00), ' ', :Status)",
StatusBy ,
StatusDate "TO_TIMESTAMP(:StatusDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",
Approved ,
ApprovedBy ,
ApprovedDate "TO_TIMESTAMP(:ApprovedDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",
TrackingNumber "DECODE(:TrackingNumber, CHR(00), ' ', :TrackingNumber)",
SVOther "DECODE(:SVOther, CHR(00), ' ', :SVOther)",
ShippedVia "DECODE(:ShippedVia, CHR(00), ' ', :ShippedVia)",
ShippedBy "DECODE(:ShippedBy, CHR(00), ' ', :ShippedBy)",
ShippedDate "TO_TIMESTAMP(:ShippedDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",
CompletedBy "DECODE(:CompletedBy, CHR(00), ' ', :CompletedBy)",
CompletedDate "TO_TIMESTAMP(:CompletedDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",
ORDERType "DECODE(:ORDERType, CHR(00), ' ', :ORDERType)",
RMAID ,
RMANumber "DECODE(:RMANumber, CHR(00), ' ', :RMANumber)",
BackOrdered ,
XORDERID ,
PARTSORDERSENT "DECODE(:PARTSORDERSENT, CHR(00), ' ', :PARTSORDERSENT)",
SHIPMENTID "DECODE(:SHIPMENTID, CHR(00), ' ', :SHIPMENTID)"
Any help in this regard will be highly appreciated!

}hi,
Thanks i used your coding and it works well...
i also used other thing i inserting the queries and values in another schema with primary and foreign keys.. it works well..
but problem is i cannot retrieve the unique constraint and other check constraint..
i cannot insert it..
and also i cannot create table in order i create the original..
because the retrieve query s values display based on ascending order i want display query in creation time...
because when i foreign keys .. the references in available before i create the table..that means a(table name) followed b(table name) .. a(table name) has contain foreign key of b(table name) .. but b (table name) not yet to create .. is possible.. to retrieve based creation time...

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.
null

Hi,
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.
