Data migration from oracle 8i to 10g

hi
i want to move data from oracle 8i to 10g. I just want to move data, and nothing else. Tables with the same names and fields are already in 10g. every thing is already there in 10g except data.
tell me some hints and solutions so that i can use imp and exp to move the data from 8i to 10g without any data loss and in a secure way.
thanks

there is another point that oracle 10g also contain some data. and tables and field names are same in 10g as in 8i. if i use "imp full=y" then is there any chance of data loss that is already in 10g? and are there any chances that data file are overwritten? tell me the risks and solutions.

Data Movement from Oracle 8i to 10g

hi
i want to move data from old system (oracle 8i) to new system (oracle 10g). database architecture for both systems is different. there are 12 tables in old system and 37 tables in new system. i want to use exp and imp utilities. new system in oracle 10g also contains so many records. i want to move data rightly and also want to secure data in oracle 10g. can i use exp and imp for it. if there are some other ways then plz write me. plz also write the precautions and considertaions that i have for using exp and imp.
cheers

Since these are two different architectures, and I understand two different OS' then the only available choice is to use export/import. The number of tables doesn't seem to be problematic.
From your other thread, Re: data movement from 8i to 10g , you stated some concert about sys' objects, don't deal with them, just import your production schema objects.

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.

Data migration from Oracle to MS SQL using SSIS

Hi friends,
I know this question must have been asked by many who are beginners to SSIS like me about migrating data from oracle database to sql server database but i still would like to raise this query again.
I have table called tbl_employee_oracle in oracle database from where i need to retrive the latest records(eg. latest record of each employee) from the table and populate the result into the sql server database table which is tbl_employee_sqlserver
using ssis.
The logic i thought of doing this is as below;
1. Retrive all employees records from oracle database table.
2. Dump these records into a temporary table(will have same table structure as in oracle database) in sql server.
3. Creating a stored procedure in sql server which will contain logic to select the most recent records from this temporary table.
4. Populate this result set into the final table of sql server.
Please suggest me if working on this logic is worth and any alternate logic to accomplish this task.

There are many opitons, but choose among for your scenario
1. If your employee table is small with less than a few hundreds of record, you want to choose SCD Type 1 if not preserving histoy, incase of preserving history of records choose SCD2,
2. If you have less than few millions of records you can choose look up to direct unmatched records to insert into Sql Server Destination and direct matched records could be updated using OLEDB Destination or Try Merge Left outer Join
transform.
3. If you have several millions of records, you may want to use your above method.
4. Configuring to use CDC could be last option where there are large volumes of updates and inserts every few min to hours. But I'm not sure if this option can be set in Oracle Source.
Please mark this post as answer if it resolves your Problem. You may even mark it as helpful. Thanks

Data MIgration from Oracle to SQL Server 2005

HI Gurus,
Kindly please advice me how to migrate Data from oracle to MS SQL Server or Vice Versa.
I came to know about 2 methods:
1) Using SQL Developer
2) USing ODBC.
KIndly let me know which method is better. I am in confusion about both option
Kindly advice over the same
Thanks

Usually such questions asked and answered on forums of a target system. In this case on MS SQL forums.
But I will answer.
You should create a LINKED SERVER in MS SQL that connects to Oracle.
Then issue couple of SELECT * INTO <TARGET_TABLE> FROM <ORACLE LINKED SERVER>..<SRC SCHEMA>.<SRC TABLE>.
Install Oracle Client and OLE DB driver on SQL Server machine.
Also, Oracle is case sensitive by default. MS SQL is case insensitive by default. If there are primary/unique keys that have mixed case values in Oracle, then in MS SQL you need to set case sensitive collation for them.
PS. If you need not only migrate data one time, but also to have a real time replication during an application transition period, you can take a look on heterogeneous replication solutions like Golden Gates or DataCurrents.

What are the Issues in Migration from oracle 8i to oracle 10g

Hi,
Can you let me know what are the issues that i face when i migrate from oracle 8i to oracle 10g. I will be very thankful if you give me a list of issues that you face while migrating from 8i to 10g

In addition to Max's reply, you must be aware that you have to test your applications agains 10g database before you actually upgrade the database.
If you use CBO, it may produce different execution plans for one query when you run it in 8i and 10g. This may affect your application performances, which you don't like to happen.
Also you have to decide how much downtime you can afford during the migration. Can you afford some downtime and how much? If you can't than this makes the situation more complicated.
How big is your database? You may end up only with simple export/import solution using export import utility.
The bottom line is, whatever you decide, you must test your applications running against 10g database before you actually upgrade your database.

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

MIgration from Oracle 9.2.4.0 to Oracle 10g Release 2 (10.2.0.1.0)

Hello
We are planning to upgrade and migrate from Oracle 9 to Oracle 10. ( both version on windows)
Would be of great help if I could avail the below information.
Most of the Instance are more than 50 gig
1 Should use a EXP / IMP or Should use DBUA ( prefer a safe method )
2.IF DBUA used any idea how much time it should take .
3.Any other method for upgrade.
We are currently in an analysis phase , we do have some instance that are already 10g but were created from scratch.
Thanks for all your help in advance
Cheers

Most of the Instance are more than 50 gig
1 Should use a EXP / IMP or Should use DBUA ( prefer
a safe method )Use DBUA , it is safer then exp/imp
2.IF DBUA used any idea how much time it should take
It depend on database , machine etc. it should not take more then 2-3 Hr
3.Any other method for upgrade.
I always use manual method and feel manual upgrade is safest.

Migration from Oracle 9i database to 10g in ECC5

Hi Experts,
We are planning to move our production system which is currently running ECC5 on AIX OS and Oracle 9i database to AIX OS and Oracle 10g database.
Some doubts regarding the above procedure:
1)Is there any possibility of SAP system migration from Oracle 9i to Oracle 10g. If yes, do we need to perform any addinitional steps for that?
2)If the above condition is OK, then what type of system copy should we need to follow: Homogeneous or Heterogeneous? Heterogeneous system copy is ususally done incase of system copy involving different databases. Does that apply for differnt versions too like Oracle 9i and 10g?
Any response is highly appreciated.
Regards,
Sanjay

If i'm using the dbua then the above issue will be solved by dbua itself?Well, DBUA will only perform a sanity check on your current release and if it doesn't pass it will fail. In other words DBUA will not upgrade your 9i release to the proper compatible release that you have to do before upgrading to 10R2.
Personally I never used DBUA, I always prefer manual upgrades, DBUA is good for you bcz it will not allow you to miss any step while upgrading.
What is the size of the database which you are going to upgrade?

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.

Live migration from oracle 8.0.3.0.0 to oracle 10g

Hello everyone,
I have Oracle 8.0.3.0.0 running on Windows NT platform. I wish to migrate from Oracle 8.0.3.0.0 to Oracle 10g. And I wish to do it without shutting down my Oracle 8 server. Sort of live migration. Since transaction rate is very high. And putting down the server would mean hanging up whole work. Is it possible. If yes what all hardware and software requirements are there? Or Import and Export is the only option,
In anticipation of your guidlines,

Durgesh,
 No, you cannot migrate directly from 8.0.3 to 10g (either 10gR1 and 10gR2). Read the upgrade guide which concern your target 10g release :
 Oracle Database Upgrade Guide 10g Release 2 (10.2)
 Oracle Database Upgrade Guide 10g Release 1 (10.1)

Hotkey (Ctrl+B) is not working after migration from Forms 6i to 10g

Dear Gurus,
Need your help regarding the following problem:
After migrating from Forms 6i to 10g (Rel 2), Ctrl+B (used to list the blocks in a form) hotkey is not working anymore (all other hotkeys are working fine). I've checked my FMRWEB.RES and it contains an entry for Ctrl+B:
66 : 2 : "Ctrl+B" : 70 : "Block Menu"
Additional Information:
OS: AIX
NLS_LANG = UTF8
fmrweb_utf8.res also contains the same text for Ctrl+B as above.
I tried to reproduce it on my Windows Machine (with NLS_LANG set to AMERICAN_AMERICA.WE8ISO8859P1) and its not working as well. I don't have right to put move files on AIX server but i can try anything (on my local system) suggested by the Oracle gurus.
Best Regards,

Dear Gerd,
"are you sure, that it is the hotkey"
Yes, i am dead sure. Since:
(1) It was working fine in forms 6i
(2) If you run a form and select Help => Keys, you will see Ctrl+B on the top of list
The problem is its not taking into account the keys which i am defining in the file (although i am following the same procedure detailed on metalink.oracle.com).

Awaiting for best possible solution.
Thanks in advance.

the 3rd party tool is ETL , you can use ETL tool and the prepare the load files then you can use LSMW method to upload the data to SAP.

Regarding database migration from Oracle to MS SQL

Hi All,
In my application, the existing database is oracle. we need to migrate from Oracle db to MS SQL.
We need procedure is as below
1.export data from Oracle and keep it in a file.(.dmp)
2.Import data to MS SQL from the exported oracle file.
and vice versa from MS SQL to Oracle.
my question is- is it possible to import .bmp (oracle export data) into MS SQL.
Please clarify me.

There are couple of options to get data from Oracle to MS SQL.
The simplest is to create a linked server in MS SQL that points to Oracle and copy data with a query like select * into my_mssqlTable from oracle.schema.table; via the linked server.
Some data types will not be supported.
That is for one time copy.
If you need a close to real time replication you can use MS replication (I would not recommend because it creates triggers on Oracle tables), or you can use GoldenGate or DataCurrents or other replication products.
