How to migrate EP6 32bit oracle 9.2.0.7 to 64bit oracle 10.2.x on Windows

Dear contributors,
I have to perform a hardware change for several EP 6.0 SP19 Systems. The idea is to replace the 32 bit hardware with 64 bit, the OS will change from Windows 2003 32bit to 64 bit, the DB is Oracle 9.2.0.7 and will be Oracle 10.2.x 64 bit.
I found a note for ABAP based systems: SAP Note 932722 - Upgrade to Oracle 10.2 during a database copy, but I'm not sure I can use this for JAVA as well.
Is there anybody out there that has performed such an operation and is willing to elaborate on the subject?
I'll be most grateful.
Regards,
Marcel.

Hi,
we asked our basis consultant about a similar project last week.
The way to go is :
Upgrade your 32 bit database to 10.2.0.2 32bit.
On a new server, install Windows x64 and Oracle 10.2.0.2 x64.
Then, do a heterogenous system copy.

How to migrate data fSQL server 2005 Tables with image column To ORACLE 11g

Hi ....
I am in the middle of migrating our database from sqlserver 2005 version to ORACLE 11g instance, and i'm facing a problem when trying to load data into one of the oracle table which has blob column and some more. The data file was extracted from sql server 2005 table which has image column and some more. All other columns are sinking with the migration as expected but the image column is not getting loaded into oralce blob.
I tried loading data using sqlloader.
Is there any other way to migrate data directly between these two versions of database?. Pls help...

Welcome to the forum,
Hi,
To link Oracle with SQL Server follow this steps:
1-Install Oracle ODBC drivers on the server (your local Oracle database) that will access the remote SQL Server database using the database link.
2. Setup the ODBC connection on the local Oracle database using the Windows ODBC Data Source Administrator
3. Test the ODBC drivers to ensure that connectivity is made to the SQL Server database.
4. Ensure that your global_names parameter is set to False.
5. Configure the Oracle Heterogeneous services by creating an initodbc.ora file within the Oracle database.
7. Modify the Listener.ora file.
SID_NAME is the DSN for the remote database.
ORACLE_HOME is the actual Oracle home file path.
PROGRAM tells Oracle to use heterogeneous services.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME=Cas30C) -- Enter the DSN on this line
(ORACLE_HOME = c:\oracle10gdb) -- Enter your Oracle home on this line
(PROGRAM = hsodbc) ) )
8. Modify the Tnsnames.ora file. This is the Oracle database installation accessed by the users to connect to the ODBC drivers
(DESCRIPTION=
(ADDRESS_LIST=
(Address=(PROTOCOL=TCP)
(HOST=
-- (Server x)
(PORT=1521))) -- Enter the port on which the server x Oracle installation
-- is listening
(CONNECT_DATA=(SID=Cas30c)) - Enter the DSN name
(HS=OK) -- Enter this value. It tells Oracle to use hetergeneous services
9. Reload the listener on local Oracle database
10. Create a database link on the local Oracle installation that accesses the heterogeneous connection, which, in turn, connect to SQL Server.
11. Run a SQL Server Select statement from the Oracle installation using the database link
Thanks

How to migrate Oracle 9i(32 bit) to oracle 10g(64 bit) DB with ASM

How to migrate Oracle 9i(32 bit) to oracle 10g(64 bit) DB with ASM on SAME platform RHEL4.0

I think Werner is suggesting you ask your question in the appropriate forum.
Go up 2 levels (to Community Discussion Forum) and look for the Database category. It's not that difficult to find, and you will be discussing the question with people who actually care about that kind of question.
The people who read and interact in this forum do so to discuss Documentation questions. Specifically questions about how to improve the documentaiton.

How to migrate data from oracle 9i database to new machine 11gr2 RAC ASM

Hi Expert
I need your expertise to advise me what is the best method to move data from oracle 9i database to new machine running oracle 11r2 RAC database with ASM.
Currently my production server running on HPUX ORACLE 9I database with normal file system. My new server is running SUN SOLARIS SPACR 64 bit ORACLE 11gr2 RAC with ASM. What is best method to move data over so it will be consistent. Any guide can refer.
Regard
William

Hi William,
See the note in metalink Migration of Oracle Database Instances Across OS Platforms [ID 733205.1] to saw the Endian Format of your OS. If is the same you can use the RMAN to convert the database to another OS, if not the only option is using export/import (Transportable Tablespaces).
To upgrade from 9i to 11g, see the note 837570.1 - Complete Checklist for Manual Upgrades to 11gR2.
To migrate your FS to ASM the only way is using RMAN, so see the note - How to move a datafile from a file system to ASM [ID 390274.1].
Hope this help you.
Best Regards,
Ruben Morais

How to migrate the data in AS/400 to Oracle

I have a customer, they plan to migrate their data from AS/400 DB2 V5R3,V6R1 to Oracle 11g. Since the source system is in production, they can only halt for 48 hours,
which way is the fastest?
ORACLE workbench can only support to IBM DB2/400 V4R3 and V4R5, must we export the data from AS400 to ASCII then sql load to Oracle, the user data size is about 3T?
even get the initial data, how to capture the increased data? Oracle GoldenGate 11g can't access AS400 as source.

Hello,
An option would be to use the Database Gateway for DRDA. With this tool, all the data in the iSeries machine will be seen like an Oracle Table.
You will be able to run statements like :
INSERT INTO <Oracle_table> SELECT <col1, col2.....> FROM <iSeries_table>@AS400
or even like
CREATE TABLE <oracle_table> AS SELECT * FROM <iSeries_table>@AS400
The Database Gateway for DRDA is more an integration tool than a migration tool. You will be able to access live data on the AS/400 like this data was in Oracle
table(s). You can even modify the AS/400 data (insert, update, delete) from Oracle. This can avoid to have to do a one-time migration.
The Database Gateway for DRDA documentation is available at http://download.oracle.com/docs/cd/E11882_01/gateways.112/e12014/toc.htm

Oracle 10g XE migrate from 32bit to 64bit becomes slower

Oracle 10g XE migrate from 32bit to 64bit becomes slower
Currently we have a database using Oracle 10g XE R2
(Oracle Database 10g Express Edition Release 10.2.0.1.0)
on a linux 32bit server.
And recently we did migrate it to another 64bit linux server.
But found after migration is it running slower at 64bit server (~ 25% slower)
1. We would wonder any tuning is required on 64bit server?
Besides, as I know Oracle XE only using single core CPU for processing.
On 32bit linux the CPU is Intel(R) Xeon(R) CPU E31235 @ 3.20GHz
On 64bit linux the CPU is Intel(R) Xeon(R) CPU E5-2470 v2 @ 2.40GHz
2. Would the CPU clock speed on a single core also made the 64bit Oracle slower?
Thanks a lot.

32 or 64 bit normally won't cause much performance difference as long as you can't use > 4GB RAM
Please note that XE can use only 1 core and 1GB memory.
According to benchmarks, Single Thread Rating of the 2 CPU really differ by around 25%. Quite consistent with your observation.
Of course, IO (i.e., disk) speed is also an important factor.

How to Migrate Oracle Forms 10g 9.0.4 to 10.1.2

Hi I would like to find information on what is necessary to do in order to migrate Forms 10g 9.0.4 to 10.1.2.
Do I need to use Oracle Migration assistant ?
Is it enough only compile forms ?
Where I find documentation on how to execute this migration. I am only find documentatio to migrate from 6i to 10g, but I need documentation to migrate from Forms 10g 9.0.4 to 10.1.2.

Hi,
Thank you for the answer about Oracle forms.
Now I would like ask another question but this time for Oracle Application Server. As we have Oracle forms 10g 9.0.4 we also use the Application Server with this same version.
Do you have any recommendations on how to Migrate the Oracle Application Server from 10g 9.0.4 to 10.1.2 ?
Thank you .

Migrating oracle 11.2.0.1.0 32bit to oracle 11.2.0.1.0 64bit on windows

Hi experts,
Please tell me steps to Migrate Oracle 11.2.0.1.0 32bit to 11.2.0.1.0 64bit on Microsoft Windows.(i.e. from Microsoft windows server 2003 SP2 to Microsoft windows 2008R2 SP1)
I am thinking to do the same via data-pump. Please provide me the necessary steps to do the same.

Changing platforms requires the database be re-built and / or the data moved using one of the following methods:
Export / Import to include the use of Datapump facilities. All versions support Export/Import but for Datapump 10.1.0.2 or higher is required
Transportable Tablespaces 10G or Later
RMAN Convert Database functions. 10G or Later
Streams Replication
Create Table As Select (CTAS)
Dataguard Heterogeneous Primary and Physical Standbys
Oracle Golden Gate

How to migrate sybase esql files(.cp files) to oracle pro*c files(.pc files

I need to migrate sybase esql files(.cp files, c file with sybase embedded sql) to Oracle pro*c files (.pc files, c file with oracle embedded sql) , could anyone let me know whether there are any tools for this or the process how to migrate.
Thanks in advance.

I don't think there are any commercially available tools that can do this particular type of conversion. Your best bet is to re-write the app or try something like this: http://linux.windows9download.net/go/3-153300-0-download.html (open ESQL) that supports multiple databases. I don't know how good it is or if it will work with latest versions of Oracle so no guarantees. Our old migration workbench used to convert the Informix eSQL C programs to Pro*C but no Sybase esql c.

I have a simple customer registration website (on top of 8.1.7 DB using oracle jdbc thin driver) as follow:
It is all under c:\weblogic\myserver\public_html\jsp\
(Which is the document root)
12 html files under c:\weblogic\myserver\public_html\jsp\

It there any how to steps to import it and be working- into Jdeveloper and deploy it against oc4j that I downloaded as a web server. I searched and contacted friends even at oracle and reached dead end.
Is there a migration from bea to oracle 9i that exist and that is tried and found to be working?
If so what are the details that makes it successfull all the way?
Can all those files be maintained in JDeveloper 3.2.3 or 9 keeping -your recommended- directory sturcture?
What are steps to setup the web server?
So that we may better diagnose DOWNLOAD problems, please provide the following information.
- Server name
- Filename
- Date/Time
- Browser + Version I.E 5.5
- O/S + Version Windows 200 Proffessional SP2
*** Because of JDeveloper ***
*** However please recommend any web server on HP or Sun ***
- Error Msg N/A
- Oracle 8.1.7 with thin JDBC driver

There are two ways of doing this:
a) You do a system copy using R3load
This will give you a "free" reoganization because the tables will be loaded into the database as if you were doing a new installation. The disadvantage is, that it takes more time and good planning.
b) you do a system copy using backup/restore together with the database upgrade
This is a fast way to get your system upgraded and if something goes wrong you can still use the old system. Check
Note 932722 - Upgrade to Oracle 10.2 during a database copy
this is a note for Windows but you can adapt it to be used on Unix/HP-UX too.
And just as a remark:
The "free" support for Oracle 10g is ending next year in June (see Note 1339724 - Oracle 10.2 Extended Support free until July 31, 2011) - after that you have to buy additional support if you want to continue to run 10g. If you run now a migration/upgrade project, why not upgrade directly to 11g?

How to migrate MySQL stored procedure to Oracle

Hi All,
I migrated mysql 5.1.42-enterprise-gpl-advanced DB to oracle using sqldeveloper 3.1.07 tool.
DB objects migrated successfully except Stored Procedures.
I verified .sql and Out files.. Capture process not captured stored procedures SQL.
Could you please suggest, where I can verify exact error or how to fix this issue.
Thanks in advance.

Hi,
The SQL*Developer version you are using is an old one and you should use the latest version available from this link -
Oracle SQL Developer
However, even the v4 version does not support the migration of MySQL stored procedures as shown in this link -
http://www.oracle.com/technetwork/developer-tools/sql-developer/supportedmigplatforms-086703.html
You will have to manually convert the MySQL stored procedures to an Oracle format, as even the 'Scratch Editor' under 'Tools - Migration' - does not have an option for MySQL conversion.
The documentation has details of the difference between MySQL and Oracle stored procedures -
Oracle® SQL Developer Supplementary Information for MySQL Migrations
in the chapter Triggers and Stored Procedures
