Oracle data migration

Hello,
1. What is the best way to migrate data from sqlserver 2008 to oracle 11g R2? We need to migrate 200 stored procedures written in sqlserver along with 5Tb of data.
2. Does Oracle 11gR2 with R language work on normal unix (Redhat 64bit machines) or this need seperate hardware appliance from oracle? Any links?

golden gate is a great product. Ive used GG to migrate from Sqlserver to oracle. Im not saying GG is the best product for this. Im just saying Ive used it and it works. Damn well

Here is my few doubts:
1. What is Oracle Staging?
2. How Oracle staging is useful for data migration?
3. I see few ETL tools for data migration such as Informatica, Ascential Datastage etc. but our requirement is how can we use oracle staging for data migration?
4. What are the benefits in using oracle staging for data migration?
Expecting your response of above queries.
Thanks,

Here is my few doubts:
1. What is Oracle Staging?It is where ODI creates temporary tables. It does the transformation and if required cleans the data aswell.
2. How Oracle staging is useful for data migration?ODI loads source data into temporary tables(staging) and applying all the required mappings, staging filters, joins and constraints. The staging area is a separate area in the RDBMS (a user/database) where Oracle Data Integrator creates its temporary objects and executes some of the rules (mapping, joins, final filters, aggregations etc.). When performing the operations this way, Oracle Data Integrator behaves like an E-LT as it first extracts and loads the temporary tables and then finishes the transformations in the target RDBMS.
3. I see few ETL tools for data migration such as Informatica, Ascential Datastage etc. but our requirement is how can we use oracle staging for data migration?
4. What are the benefits in using oracle staging for data migration?You can refer https://blogs.oracle.com/dataintegration/entry/designing_and_loading_your_own

Hi Zuhair,
If you give details of the problems you are still having then we should be able to get SQL*Developer to work.
However, if you don't want to use SQL*Developer then the following options are taken from note 393760.1 available in Metalink if you have access to that -
1. Use a gateway that supports the non-Oracle database or generic connectivity if a third party ODBC driver is available to do a -
'create Oracle_table as select from non_oracle_table@database_link'
for each table. You would then have to manually create all the other objects (views, indexes, stored procedurs etc) and permissions etc that existed in the non-Oracle database.
2. Use the SQL*Plus COPY command to copy data from the non-Oracle database to the
Oracle database using a gateway or generic connectivity. The syntax is as follows:
COPY FROM username/password@oracle_sid -
INSERT destination_oracle_table -
USING query;
The following example selects all rows from the EMP table in the non-Oracle database and
inserts them into the local Oracle EMP table:
COPY FROM SCOTT/TIGER@ora10 -
INSERT EMP -
USING SELECT * FROM SCOTT.EMP@gateway;
where "gateway" is the database link created for the gateway.
3. Load the non-Oracle data into flat files and use SQL*Loader to put the data into Oracle tables. Again manual
work is required for the other objects.
4. Contact the Oracle Product Technology Services (PTS) group for assistance. See the webpage -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
5. Use a third party migration tool. See -
http://www.oracle.com/technology/tech/migration/isv/third_party.html
6. Use JDBC to connect to the non-Oracle database and Java in the Oracle database. This method will work but it is not suppported by the JDBC team.
=========
The amount of work involved will depend on the number and size of Access tables that you want to migrate.

Mike

Hi VKMP,
As well as reading the documentation thoroughly the following note available in My Oracle Support may be useful -

URGENT - Data Migration - From Oracle BPEL 10.1.2.0 to current version

Anyone having any idea on the data migration appraoach to be followed from Oracle BPEL 10.1.2.0 to 10.1.3.3
If it supported?
I understand process migration is possible (I found it out in installation guide for 10.1.3.1) but there are no documents available for data migration approach (Or I am not able to get hold of any).

To workaround the problem, from the DataModel project, right-clicked Project Properties, selected Business Components: Options, unchecked Validate Objects during Compile, and the project compiled successfuly, yet the issue is to have my xml files valid.

Is there another option apart from export an import. We run a high transaction 24/7 database currently on 8i. With minimal downtime what will be my best option to migrate to 10g.
Is there a utility from oracle, like a log reader, which reads the transaction logs from 8i so we don't loose on any transactions during the migration process.
Current Sinerio:
Oracle 8i on Win2K - In production 24/7
Oracle 10g RAC on SLES10 - New
Oracle 10g is up and running, and the data from 8i is imported into 10g using (exp/imp). I just want to get the latest data from 8i to 10g server.
Any ideas?

Informix 7.x to Oracle 9i Data migration

Hi All,
I'm in the process of migrating the data from Informix 7.X databse to Oracle 9i. I need to migrate data from selected columns and selected tables only from the informix schema.The data migration deals with Huge volumes[ Around 50GB ] of data.
I need some help regarding
1. I'm thinking to use Informix Unload Option for data unloading and SQL * loader for loading the data into the database. Is there any other better way.
2. how to deal with the memory issues during migration process.
Regards
Gaurav

Hi,
Thanks a ton for the prompt response.
I'm elploring the usage of Migration Workbench for the migration.But yet don't know the correct way to use it.
I need some inputs and material to refer from this end.
Apart from that Regarding memory :
As I'm dealing with 50GB of data
1) I want to foresee any problems which i might encounter during the migration process.
2) Any oracle specific parameters I need to setup to rule out any memory related migration failures.
3) How can i do the migration in the quickest way?
Kindly do the needful.

Data Migration from MS Excel Sheet to Oracle 9i Database

Can anyone please help me to perform a data migration from MS excel sheet to Oracle 9i Database. I have an excel sheet from which i need to move data to the database. One of the columns in the sheet posseses multiple new line characters, and which causes a problem while migrating data with the help of SQL Loader. I would like to know whether any utility is available to migrate data directly from MS Excel sheet to the database, or it would he really helpfull for me , if anyone provide me with an alternate solution.

I think Christian's suggestion will work for easily and quickly.
1) create table link of Oracle target table in MS Office's ACCESS thru ODBC;
2) from Access screen, you may easily dump the excel data into the linked table.
This is very easy and feasible ways. Don't bother to find other ways. The other ways will need you to clear the unwanted carriage return signs first.

Migrating Oracle data to SQL

I am receiving the following error message when attempting to migrate Oracle data to SQL Server 2008. The migration tool being used is SSIS 2008 wizard. Only a few table objects are impacted by this migration.
Thank you in advance for your assistance.
ERROR:
Data Flow Task: OLE DB Destination [1]: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.

Sorry, but we can't help you. This is a forum for Migrations from Foreign Databases (like SQL Server) to Oracle, using the Oracle SQL Developer Migration Workbench.
SSIS is a Microsoft product, and your migration is going the other direction, so you need to ask in Microsoft forums.
I just googled for "Cannot retrieve the column code page info from the OLE DB provider", and there were several hits in MSDN.

Oracle 9i to11g data migration

Hi,
Could you please suggest the best method (Tool) to export data (Data migration) from Oracle 9i to 11g
Thanks,
Bhaskar

Pl indicate which exact versions of Linux - are the source and target servers the same or different ? If they are the same, use DBUA to upgrade. If they are different, shut down the database on the source, copy over all of the database files to the target, then perform a manual upgrade on the target.

H/W & Data migration form AS 400/DB2 V5 R4 to Unix/Linux and Oracle

We are considering migration of huge data(in Terabytes) from AS 400/DB2 V5 R4 to Unix/Linux and Oracle.
We are changing operating system and data base also..Please advise if R98403 can be used to move data in terabytes.
I understand Oracle work bench does not support V5 R4.
I would like to know pointers on possible tools and approach for the migration.
Thanks
Las

Hi,
May I know the reason for this huge change? As most of the current setups of E1 are on AS00 only. Then also if you are planning to migrate your hardware and data from DB2/OS400 to Orcle and Unix/Linux you can consider below options for data migration:
1) R98403 and R98403A are best approach for this type of migration it may consule some extra time but accurate..! As no other tools like Oracle Workbench can
provide 100% accuracy.
2) Archive data size if possible with the help of BA team and work on some purging this will help you to great level.
3) If you decide to go live on new setup please consider going live module wise as a specific module data can be moved fast, and if BA team can specify some specific tables only getting hit for module trasection they can develop TC reports for specific data to be migrated and can save your time instead of copying entire data set again at go live.
Good Luck..!
Thanks,

Invoking EBusiness Suite APIs from Oracle Data Integrator

Hi,
I am using ODI as the data migration tool to load data from oracle legacy application to ebiz.
Is there any knowledge module available to call oracle Ebusiness APIs?
Thanks in advance.
-Santanu

Thanks for your response.
In eBusiness we have either open interface table & concurrent program or API. IKM which you have referred those are used for open interface and concurrent program. How to handle APIs where there is no open interface table. For example AR_RECEIPT_API_PUB.CREATE_CASH which is an API and there is no open inetrface table for this.
Cheers,
Santanu

CrystalReports error in XI 3.1 with Oracle Data Source

Having trouble running Crystal Reports with Oracle data source off XI 3.1 SP3. Reports hang through CMC or InfoView. Have no trouble on identical environment (presumably) with the same reports. Basically this happened after migration.
Report can be run on designer on the server box (suggesting the connection is good) however once uploaded to CMS, it hangs with error. This is not about an specific report only reports with Oracle Data source (Oracle client already installed and connection established)
Any comments appreciated.

Thank you for your reply.
Seems like a re-boot resolved the problem.

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.
