SQL 7 to Oracle migration

Is there any information available on a strategy for designing a DB schema that will be initially deployed on SQL Server 7, but will eventually be scaled to an Oracle server? I want to know some pitfalls to avoid so that the eventual migration proceeds as smoothly as possible.
TIA,
Michael Chapman

Hi Michael,
We don't have such a document. If it's scalability you want then I would design with Oracle from the start. We have had a lot of people requesting the Workbench for SQL Server 7.0 migrations.

SQL to Oracle Migraton - Unable to create source model in Migration Workben

We are trying to use Oracle Migration Workbench utility to transfer data from SQL to Oracle. when we start creating the source model we get the following error :-
failed to load source model ora-01401 inserted value too large for column.. this is the error at the ss2k_syslogins table. this is a logical model creation from sql server db.
In case if this is a data issue with the syslogins table/view, is there any way to overcome this or whether we can do any settings at Workbench Level to overcome this..
Thanks in advance,
John.

I think I figured it out.
1 - I used the Migration Work Bench that came with the 9.2.0.1 client - BAD IDEA.
2 - I down loaded the OMWB (10.x) - GOOD IDEA. I also downloaded the plugins so that the versions would match each other. Get rid of any existance of the 'old' OMWB directory under the OracleHome, so as not to get confused.
3 - I realized that you just extract the OMWB.zip file to the C: drive like some third world DOS application, so it won't show up in under your start menu.**
**I find this kinda cheesy that the Oracle installer is not involved here to add it to the Oracle Configuration and Migration menu in start up. I suppose you can copy the unzipped struture over top of the existing clint directory structure, but still dumb.
3 - The other odd piece, you down load the plugin as a zip (and not a jar), BUT DON'T UNZIP IT!! Rather place it in the ..\plugins directory, underneath wherever you unzipped the OMWB, and RENAME IT with a .JAR extension (again don't unzip).
4 - Make a shortcut on your desktop to the omwb.bat file (from where ever you unzipped the OMWB product)
5 - Fire up that icon and the product will look at the new .JAR in the plugin folder and 'tada', you have OMWB with your specific database plugin available.
The new product didn't hang for me. Now I just need to figure out how port this into a shema name OF MY CHOSING, and not the generic OMWB_Login1 that it created.
I f anyone has info on that, let me know.... I think its in the destination creation (step two of the whole process).

Error when using Oracle Migration WorkBench (Sql Server 2k to Oracle 8i)

I'm trying to migrate a Sql Server 2k database to an Oracle 8i schema using OMWB. After using BCP to collect metadata information on the source database, I tried to capture the source data model and got a "Capture aborted" message on the progress screen (even though then it appears a dialog window reporting "0 errors and 0 warnings", funny!). Down there is the error log OMWB generated. After reading some posts, I changed some columns of the OMWB dictionary that holds the source database name, but still got the same error. If someone can enlighten me on this toppic, I'd greatly appreciated it.
Here's the error log of OMWB:

How to migrate my-sql into ORACLE!

I have this database running in my-sql. nOw i want to convert into ORACLE.Can anyone shed light on this please..does sql loader
support this?
Thanks in advance..your help will be much appreciated..
ashish

Do you want to migrate code or data?
If its code you'll probably have to do a manual rewrite. Sometimes there are utilities to convert code from one system to another, but some manual fixes are usually necessary even when these exist.
If its data there are copy utilities. As Satish pointed out you could use SQL*Developer, or possibly Oracle Migration Workbench

Sql LOader- Mysql Migration to Oracle

Hai all,
I am using Sql loader to migrate Mysql Database to Oracle 10g.
Almost all the migration is succesfully done but i have got stuck at one point. Since We know that in Mysql there is Null Date format is 0000:00:00 00:00 and when i am trying to load this date in oracle it says that cannot insert 0 in date.
Since In my mysql there is date combination of both regular dates and 0000:00:00 ..... so i want that what shoud i use in Sql*Loader that .When it seen the 0000:00:00 in date column it insert the date 1900:01:01 and when it sees the reglular date ..it simply insert in date .
Thanks and Regards!!
Pankaj

Hi,
The decode command I mwntioned means
if :date = 0000:00:00 00:00
then
to_date('1900:01:01','YYYY:MM:DD')
else
to_date( <give your date format> )
end
Change your command to
publishtodate "decode(:publishtodate, '0000:00:00 00:00', to_date('1900:01:01','YYYY:MM:DD'), to_date(:publishtodate,'YYYY/MM/DD' ) )"
The last bit (i.e. to_date(:publishtodate,'YYYY/MM/DD' ) ) is the else part, which will load the actual date data.
Here you have to give the format of dates of your MySql generated data.
Whats the format of date data? I guess, its not just YYYY/MM/DD, there must be time component (as the error text says).
If the dates are like "2007/05/21 23:45", then give the format "YYYY/MM/DD HH24:MI" or else follow your format.
Cheers

Tools for migrating data (documents) from MS SQL to Oracle

Hi,
Please let me know if there any tools available for migrating documents from one database like MS SQL to Oracle. Currently our documents are stored in MS SQL and we are planning to implement KM for document management with Oracle as the database.
Regards,
Suresh

The old manual style still works - create the scripts for the migration objects, then use search & replace to rename the schema for all affected objects and finally run the SQL script to create them in the Oracle database.

MS-sql to Oracle 9i Migration

We have planned to use Oracle migration work bench for migrating data from MS-SQL server to Oracle 9i for one of our clients. I would like to know in Oracle migration work bench, Is it possible to save the mappings done once and re-use the same for next migartion. i.e I want to configure all the source and destination database,tables etc.. deatils and save the same and want to re-use the same.
Pleas throw some light on this.
Regards
Sadique.

Sadigue,
The Workbench uses an underlying repository, so all the choices you make are saved. However the primary usage of the tool, is one off migration, not continous migration. If you want to rerun multiple times, you should probably generate the offline schema and data migration scripts.

Hi,
Does anyone know that can Oracle Migration Workbench 2.0.2.0.0
be used to migrate SQL 7.0 to Oracle 8i? or the version
2.0.2.0.0 can be only used for Oracle 9i?
I failed to install Oracle Migration Workbench 2.0.2.0.0 onto my

Migrating from SQL to Oracle 9i on Linux

Hello
I need to know where can I find information on migrating database from
SQL to Oracle - 9i on Linux.
Are there any tools available for this.
Thanks & Regards
Prakash
[email protected]

Prakash,
At the moment we recommend running the Oracle Migration Workbench on Microsoft Windows and connecting to the Oracle 9i server by Oracle networking (sql*net). We apologise for any inconvenience this might cause. The released Oracle Migration Workbench for linux is an old version and the current version on Microsoft Windows is much improved. I am not clear what you mean by SQL, the workbench supports migration from products by Sybase, Microsoft, Informix, IBM and MySQL, see the support and plugin download web pages for database product names and version numbers, of the databases to be migrated from.
I hope that helps,
Turloch

ODBC errors for Oracle Migration Workbench and SQL Server 2000 on Windows

Hi all-
I setup a new ODBC connection for the Oracle 10g Migration Workbench to MS SQL Server 2000 on Windows XP and keep getting the following errors when I try to
either test the new ODBC connection to MS SQL Server 2000 for use with the Oracle Migration Workbench tool. Goal is to fix these errors so that I can migrate our test SQL Server 2000 databases to Oracle 10g.
Current configuration
- Oracle 10.1 Migration Workbench
- Oracle 10g Database (target)
- MS SQL Server 2000 (source database)
-Windows XP
-ODBC 3.85.1117 driver for Windows XP with SQL Server and Oracle
Errors:
I. When I test the ODBC connection:
Microsoft SQL Server ODBC Driver Version 03.85.1117
Running connectivity tests...
Attempting connection
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Specified SQL server not found.
TESTS FAILED!
Now here is what has me totally confused:
I can use the command line ISQL to access the database on the server and IP is all correct and port is available. So I can access the SQL Server database fine it is when I try to setup ODBC that it gives me problems.
Any tips how to get this ODBC working?
Thanks
Ben Prusinski

1. Jing Jin. If you had READ the post you would have seen that installing later versions is NOT an option.
2. Not supported does NOT mean does NOT work, as Balmukund pointed out in the referenced thread. The site that this databases supports is using ASP which is also NOT supported by Microsoft. As it turns out Balmukund's solution actually turns
out to be the correct solution. I installed SS2K and its Service pack 4 on the machine last night. Good answer Balmukund. as we say in the Navy, "BRAVO ZULU!!" which means "WELL DONE!!
3. Tom Li I just posted the question less than 48 hours ago. My last post was less than 24 hours ago. I think I have the right to be given the opportunity to determine whether a reply is the answer or not. I understand you don't like unanswered
posts sitting around for weeks, months or years. (I don't like it either as I have a few that are still unanswered after several years.) But you should not be showing replies as answers before I even get a chance to see them, much less try them out.
You should also not be showing replies as answers which don't address the criteria of the question. I specifically stated that I had to install SS2K. I went on to state, "And before anyone asks I need to install this version because that is what
the customer is using and I need to duplicate their databases." So the correct answer, if in fact SS2K did not work on Windows 7, would have been a virtual machine answer, as suggested on the thread Balmukund referenced. So before you mark a reply
as an answer read the question.

SQLServer to oracle migration. Issue with table having image data.

Hi,
I am using the SQL Developer version 1.5.0.53 Build MAIN-53.38. I am trying to migrate from sql server database to oracle. Sql server database version is 2005 and oracle database version is 10g (10.1.0.2 and 10.2.0.3). Both Oracle and Sql server databases are on windows-xp.
Everything (including data) migrated well except for the one table having blob (oracle) and image(sqlserver). I am getting the following error in sql developer while migrating data for the blob from sql server to oracle.
Data Move information:Rows : 497 Errors: 10278
Commit failed: Closed Connection
Must be logged on to server
[POCRepository].[td].[REPOSITORY] Closed Connection
Io exception: Software caused connection abort: socket write error

No more data to read from socket
[POCRepository].[td].[REPOSITORY] No more data to read from socket
Inserting ' ' into column td_POCRepository.REPOSITORY.RP_DATA (Row number 498)
I have created sqldeveloper.cmd file as suggested in other threads and I am using the same java provided with SQL Developer 1.5.0.53.
The database alertsid.log shows the following error messages for this activity.
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [0x34EF9E5] [] [] [] []
ORA-00600: internal error code, arguments: [kghasp1], [0x5F3B718], [], [], [], [], [], []
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [0x34EF9E5] [] [] [] []
The error ORA-00600[kghasp1] refers to the problem with heap memory. I also restarted the database and tried the data migration for only this table but with the same error.
I tried it on both 10g release1 and 10g release 2.
Can someone please help me in resolving this issue.
Thanks
Raghavendra

Hi Raghavendra,
Are you saying the Microsoft SQL Server bcp dump of image data failed? It has been tested, it results in a hex dump rather than a binary dump, hence the clob to blob, and hextoraw workaround.
What are the version numbers and what is the reproducible test case?
-Turloch
Note that the clob to blob process is automated:
Tools->preferences->Migration->Generation Options->General Options->Generate Stored Procedure for Migrate Blobs Offline
From Help:
Generate Stored Procedure for Migrate Blobs Offline: Causes a stored procedure named CLOBtoBLOB_sqldeveloper (with execute access granted to public) to be created if the schema contains a BLOB (binary large object); this procedure is automatically called if you perform an offline capture. If this option is not checked, you will need to use the manual workaround described in Populating the Destination Database Using the Data Files. (After the offline capture, you can delete the CLOBtoBLOB_sqldeveloper procedure or remove execute access from public.)

Error after Oracle Migration from DMTS into LMTS

Hello ,
I'm sorry, I posted my question again from ABAP General into this forum ABAP Dictionary. I think that here someone can help me in order to proceed with my job in the Development and in production system.
We are using SAP R/3 4.6C, with SAP kernel 2271, Oracle 9.2.0.5 and HP-UX 11.23
I did the Oracle migration from dictionary into locally managed tablespaces on the QTS system (and before that the same migration on a separate system as a copy from production):
1. export data and index tablespace with Oracle export command (exp: for PSAPCLUD and PSAPCLUI)
2. import into file for creation of indexes
3. Drop the data and corresponding index tablesspace with brtools - brspace
4. recreate the tablespaces with sapdba or with sqlplus (using the ddl scripts created before dropping the tablespaces) - - I think is my problem
5. import the data with Oracle import command
6. import the indexes from the previously created sql file
7. check optimizer statistics, analyze and next extents
But there is one problem.
Because I have also used the sapdba and ddl sql for recreating the tablespaces, I didn't specify the SAP data class for the newly created tablespace.
And in the tables TAORA, IAORA and DDART (what is very unclear for me) 3 rows missing for the USER1, TEMP and ??? data class.
If you try to import some transport in the corresponding tablespace which data class is missing an error ocur.
I have read the Note 646681 - Reorganizing tables with BRSPACE, and I saw the part: If the <reorg_tsp> tablespace contains any of the following tables: SDBAH,SDBAD,DBAML,DBATL,MLICHECK,TGORA,IGORA,TSORA,TAORA, IAORA,SVERS,DD02L,DD09L,DDNTT,DDART,DARTT or SAPLIKEY (SAPLIKEY is only available in NetWeaver 2004s or higher), then you should move them to the tablespace <aux_tsp> by online reorganization using BRSPACE:
brspace -f tbreorg -t <table_list> -n <aux_tsp>
Do you have the same problem?
Do you know how I can solve the problem now after the hole migration was done?
How can I dedicate tablespace data class?
Is it enought to just enter the same rows into the TAORA, IAORA and DDART?
Thanks,
Many regards,
Ruzica

Apparently you are trying to mix 32-bit code and 64-bit code. You must ensure that the 32-bit or 64-bit option is used consistently on every command, compiling and linking. The form of the option can depend on the version of the C compiler you are using, and whether you are on an x86 or sparc system. Consult the Pro*C and C compiler documentation.

Sql Developer MSSql Migration, Online data move, image to long raw mapping

Hello,
my task is to migrate a MSSql Server Database to Oracle 10.2.0.4 with SQL Developer Version 2.1.1.64
and JTDS JDBC Driver oracle.sqldeveloper.thirdparty.drivers.sqlserver 11.1.1.58.17.
Capture, convert and online data move works except data mapping from MSSql image to Oracle long raw dataype.
I need to map MsSql image to oracle blob, to achieve online data move!
is Sql Developer online migration MsSql image to oracle long raw possible?
I know that long raw is outdated, but i'm dba and not responsible for the software part.
What options should i try? offline data move? can MS Bulk Copy Program export image data and SQL*Loader import into long raw?
Any experience or tipp?
Thanks
Michael

Hi user12132314 ,
I do not see any 'long raw' options on our current SQLServer 2005 data type mapping. (Raw is a separate 2000 byte data type).
The usual route for SQLDeveloper is to go to Blob.
Online - this is simple & automated.
Offline - this actually goes via hex output in bcp to sqlldr, read in as CLOB which is then encoded to blob. (This is automated)
(Online 'Copy to Oracle' option, right click on table, may be of use if advanced features not included in the select such as defaults are not required, it copies over a select * from table, including blobs)
To move you from blob to long raw after migration can be done (easily enough if Oracle database >=10g so the stream does not have to be in smaller 'chunks')
http://asktom.oracle.com/pls/asktom/f?p=100:11:3938270166267830::::P11_QUESTION_ID:702825000306
I can look into this if you want to go down this route.
Note however that long raw has drawbacks and blob is preferred, see
Oracle® Database SQL Language Reference
11g Release 2 (11.2)
Part Number E17118-04
Data Types
LONG Data Type
for example one restriction is:
A table can contain only one LONG column.
