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.

MS SQL to Oracle 8i Migration

Hi!
We need to migrate from MS SQL 7.0 to Oracle 8i.We are planning to use OMWB for this..
The database size is 40MB and 250 Tables.
The queries are mostly in VBScript.. Approxmately 20 SP and 700 Generated programs are need to be converted..
Can somebody suggest how i can estimate the man-hours required for this effort..
OR any other advice and pointers are appreciated.
Regards,

Thank you all, at the end, i have fixed the problem. It seems root cause of the problem is my regional settings.
I have completed to transfer my Sql schema to Oracle with errors. Migration Wizard gives errors in the stage of creating relations. It is something like that,
Failed to create foreign key: ORA-02298 Cannot validate - Parent keys cannot find
I have also tried to migrate my sql data but when the wizard finishes running, a large amount of my data is also lost.
Do you have any suggestions?
Thank you.

Frequently transfering databases between MS SQL and Oracle

Hello all,
I am looking for a solution to easily, efficiently and be able to migrate/transfer databases between MS SQL and Oracle frequently.
I need to be able to replicate a databases on Ms SQL and Oracle for testing purposes. I will need to do this on frequent basis - almost once a week.
Please suggest what would be the best way.
Thanks in advance.

Hi Justin,
You have guessed it right to a great extend. Yes dont actually need to develop, rather need to test an application that supports SQL and Oracle databases. Now when testing the application its obviously vital to create proper systematic test data. This usually takes a lot of time and effort from the testing team/team-member. So, yes what I need to do is create the test data on one database(may it be SQL or Oracle) and migrate/transfer the data into the database on another server( ie. SQL to Oracle or Oracle to SQL).
So,
Are you developing a product that works against both SQL Server and Oracle and trying to synchonize development efforts?Yes, thats correct to extend, I need to test an application against both the servers, as it supports both types of databases, and try to reduce the test setup efforts (literally double the amount) that go in after manual creating same data on each type of database.
Are you trying to replicate structural changes between systems?I am not 100% sure, what you mean by this. But whats important and enough for me is to replicate the data. It would not be a lot of work to run the scripts and create empty schema objects.
Are you trying to replicate data changes between systems? The fact that you're only doing this weekly suggests that you're not working in a traditional replication environment.Yes, again as I mentioned above. It would be sufficient for me to just get a copy of the initial dataset. And then replicating changes to it would not be that important. However, if I can achieve a solution to this, I can by all means create a new database on the one server (SQL or Oracle) and take the data-set of the most recent/correct changes and replicate it on the other type of server as and when needed.
No - this is not a traditional replicating environment. I say weekly, because it is usually once in a week or forthnight that someone from the team will need to spent time to manually copy the test-data onto the another type of server in order to run the same testcases on two types of servers.
How do you handle conflicts (i.e. if I modify a row in both systems, which modification wins)? This is not really a problem in my scenario, as I only need to be able to transfer the data across to the different server and forget about the two databases actually being in-sync.
I have also, looked at DTS for a possible solution on SQL, however it seems highly un-realistic, having to map somewhere like 250 tables from the a drop-down list, only because the two database servers use different cases to represent tables internals. So, table 'Table' in my application's SQL database is called 'TABLE' is my applications Oracle database. DTS is highly inefficient in dealing with this. Also, having 250 tables move makes this a bit of a pain.
Thank you Justin for your response; I highly appreciate your inputs.

URGENT: Migrating from SQL to Oracle results in very poor performance!

*** IMPORTANT, NEED YOUR HELP ***
Dear, I have a banking business solution from Windows/SQL Server 2000 to Sun Solaris/ORACLE 10g migrated. In the test environment everything was working fine. On the production system we have very poor DB performance. About 100 times slower than SQL Server 2000!
Environment at Customer Server Side:
Hardware: SUN Fire 4 CPU's, OS: Solaris 5.8, DB Oracle 8 and 10
Data Storage: Em2
DB access thru OCCI [Environment:OBJECT, Connection Pool, Create Connection]
Depending from older applications it's necessary to run ORACLE 8 as well on the same Server. Since we have running the new solution, which is using ORACLE 10, the listener for ORACLE 8 is frequently gone (or by someone killed?). The performance of the whole ORACLE 10 Environment is very poor. As a result of my analyse I figured out that the process to create a connection to the connection pool takes up to 14 seconds. Now I am wondering if it a problem to run different ORACLE versions on the same Server? The Customer has installed/created the new ORACLE 10 DB with the same user account (oracle) as the older version. To run the new solution we have to change the ORACLE environment settings manually. All hints/suggestions to solve this problem are welcome. Thanks in advance.
Anton

On the production system we have very poor DB performanceHave you identified the cause of the poor performance is not the queries and their plans being generated by the database?
Do you know if some of the queries appear to take more time than what it used to be on old system? Did you analyze such queries to see what might be the problem?
Are you running RBO or CBO?
if stats are generated, how are they generated and how often?
Did you see what autotrace and tkprof has to tell you about problem queries (if in fact such queries have been identified)?

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).

SQL 2005 to Oracle 10g migration

We are migrating from SQL 2005 on Windows to Oracle 10g on Linux. If any one has experience with this kind of migration please share the steps involved.
Also is it possible to migrate subset of data from SQL to Oracle or is migrating entire data/schema the only option?
Any help or direction in this is much appreciated.Thanks in advance

Hi spulyala,
There is no clear and simple way of doing this.
-The online data move migrates from one java connection/table to another java connection/table so you would need to have the source table already filtered.
-The offline data move dumps the information out of SQL Server one table at a time, a where clause may be able to be applied manually at this stage, and loads the data in using Oracle sqlldr.
Of course you can filter and manipulate the tables within SQLServer before migration, within Oracle after migration, and delete table representations from with the tool.

IBM DB2 to Oracle Database Migration Using SQL Developer

Hi,
We are doing migration of the whole database from IBM DB2 8.2 which is running in WINDOWS to Oracle 11g Database in LINUX.
As part of pre-requisites we have installed the Oracle SQL Developer 4.0.1 (4.0.1.14.48) in Linux Server with JDK 1.7. Also Established a connection with Oracle Database.
Questions:
1) How can we enable the Third Party Database Connectivity in SQL Developer?
I have copied the files db2jcc.jar and db2jcc_license_cu.jar from the IBM DB2 (Windows) to Oracle (Linux)
2) Will these JAR files are universal drivers? will these jar files will support in Linux platform?
3) I got a DB2 full privileged schema name "assistdba", Shall i create a new user with the same name "assistdba" in the Oracle Database & grant DBA Privillege? (This is for Repository Creation)
4) We have around 35GB of data in DB2, shall i proceed with ONLINE CAPTURE during the migration?
5) Do you have any approx. estimation of Time to migrate a 35 GB of data?
6) In-case of any issue during the migration activity, shall i get an support from Oracle Team (We have a Valid Support ID)?
7) What are all the necessary Test Cases to confirm the status of VALID Migration?
Request you to share the relevant metalink documents!!!
Kindly guide me in-order to go-ahead with the successful migration.
Thanks in Advance!!!

Hi Klaus,
Continued with the above posts - Now we are doing another database migration from IBM DB2 to Oracle, which is very less of data (Eg: 20 Tables & 22 Indexes).
As like previous database migration, we have done the pre-requirement steps.
DB Using SQL Developer
Created Migration Repository
Connected with the created User in SQL Developer
Captured the Source Database
Converted Captured Model to Oracle
Before Translation Phase we have clicked on the "Proceed Summary"

We have seen only "Missing" in the chart, also we couldn't have any option to trace it in Log file.
Only after the status is VALID, we can proceed with the Translation & Migration PHASE.
Kindly help us how to approach this issue now.

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.

This needs the user to have access on all_objects view and it will limit the result upto the numbers of objects returned by the all_objects view.

SQL 2000 to Oracle 8i Migration

Does anyone have any idea about migrating MS SQL 2000 stored procedures to Oracle8i? What kind of conversion does it do? What are the restrictions? Can anyone throw some light as to where I can get the documentation etc?
Alternatively, MS SQL 7.0 to Oracle8i stored procedures conversion documentation will also be helpful?
Are there any issues with this conversion product?
Thanks

hi Kevin,
For the benefit of some other people I would just like to complete the thread. We have exchanged some e-mails already. The following approach may help some other people.
We hope to start work on a SQL Server 2000 plugin towards the end of the claendar year and it should only take us 2 months to complete at most. At present we are scoping this effort out.
We may actually start development earlier.
One alternative that may work for some people is to downgrade their SS2000 schema to SS7.0, migrate that using the workbench. Then generate the BCP and SQL Loader scripts to migrate the data from the SS2000 database.
However, if you have taken advantage of SS2000 specific functions then the Workbench may not be able to handle these specific features.

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

Migration of Oracle 8i PL/SQL to Oracle 9i PL/SQL

Hi,
Can anybody help me giving information about mandatory requirements to migrate from 8i to 9i. Also please let me know if any documents related to that for PL/SQL and PRO * C migration from 8i to 9i.
Thanks with Regards,
Guru

Are there any issues that you are facing?
If your software was well tuned and working fine under Oracle8i, you may just be able to port it right into Oracle9i without any issues.
Ofcourse, If may also depend upon how the Oracle9i instance and database has been setup by the DBA.

Oracle Database Migration Assistant for Unicode (DMU) is now available!

Oracle Database Migration Assistant for Unicode (DMU) is a next-generation GUI migration tool to help you migrate your databases to the Unicode character set. It is free for customers with database support contracts. The DMU is built on the same GUI platform as SQL Developer and JDeveloper. It uses dedicated RDBMS functionality to scan and convert a database to AL32UTF8 (or to the deprecated UTF8, if needed for some reasons). For existing AL32UTF8 and UTF8 databases, it provides a validation mode to check if data is really encoded in UTF-8. Learn more about the tool on its OTN pages.
There is a new Database Migration Assistant for Unicode. We encourage you to post all questions related to the tool and to the database character set migration process in general to that forum.
Thanks,
The DMU Development Team

HI there!
7.6.03 ? Why do you use outdated software for your migration.
At least use 7.6.06 or 7.7.07 !
About the performance topic - well, you've to figure out what the database is waiting for.
Activate time measurement, activate the DBanalyzer with a short snapshot interval (say 120 or 60 seconds) and check what warnings you get.
Also you should use the parameter check to make sure that you don't run into any setup-induced bottlenecks.
Apart from these very basic prerequisites for the analysis of this issue, you may want to check
SAP Note 1464560 FAQ: R3load on MaxDB
Maybe you can use some of the performance features available in the current R3load versions.
regards,
Lars
p.s.
open a support message if you're not able to do the performance analysis yourself.
