Migration oracle database 8.1.7.3 to 10.2.0.2

Hi,
I have a problem to migrate my database in 8.1.7.3 to 10.2.0.2 on different database server because the size fo this database is 2200Gigas.
With RMAN or copy it's not possible because the database version are different.
The solution is the export/import but it's probably too long.
Anybody have a solution

The other solution is "Database Upgrade". Here are the basic steps whci you can perform for this:
1) Install oracle 8i (with same patchset as the old one) and oracle 10g on new server
2) Restore the RMAN backup of your 8i database on new server and start the database using 8i home.
3) Apply 8.1.7.4 patch on 8i DB
4) Either run DBUA or use manual update to update you 8i DB to 10g
Here is the doc for Database Upgrade process:

How can i migrate oracle database data to DB2 database

Hi
how can i migrate oracle database data to db2 database.
can anyone provide me solution.

BTW why do you want to migrate oracle database data to db2 database? Any specific project requirement like Parallel run with Oracle database (e.g data replication)? Or any other issues - Cost? Manageability? Availability? Business requirements?
Do you need to do a day-to-day data transfer or it is for permanent migration?

To back up a 32-bit Oracle home database:
Start SQL*Plus:
C:\> sqlplus /NOLOG
Connect to the database instance as SYSDBA:
SQL> CONNECT / AS SYSDBA;
Create a .trc file to use as a template to re-create the control files on the 64-bit computer:
SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
Shut down the database:
SQL> SHUTDOWN IMMEDIATE;
Perform a full offline backup of the database.

G.7.2 Migrating an Oracle Database 10g Release 1 (10.1) Database
To migrate an Oracle Database 10g Release 1 (10.1) database for 32-bit Windows to an Oracle Database 10g Release 1 (10.1) database for 64-bit Windows:
Install Oracle Database 10g Release 1 (10.1) for 64-bit Windows.
See Also:
Oracle Database Installation Guide for Windows
Create the new Oracle Database 10g Release 1 (10.1) service at the command prompt:
C:\> ORADIM -NEW -SID SID [-INTPWD PASSWORD ]-MAXUSERS USERS
-STARTMODE AUTO -PFILE ORACLE_HOME\DATABASE\INITSID.ORA
The following table provides more information on the values you must supply.
Parameter      Description
SID     SID of the database you are upgrading
PASSWORD     Password for the new Oracle Database 10g Release 1 (10.1) for 64-bit Windows database. This is the password for the user connected with SYSDBA privileges. The -INTPWD option is not required. If you do not specify it, then operating system authentication is used, and no password is required.
USERS     Maximum number of users who can be granted SYSDBA and SYSOPER privileges
ORACLE_HOME     Oracle home directory. Ensure that you specify the full path name with the -PFILE option, including drive letter of the Oracle home directory.
Copy the 32-bit datafiles to the new 64-bit Oracle home.
Copy the 32-bit configuration files to the 64-bit Oracle home.
If your 32-bit initialization parameter file has an IFILE (include file) entry, then copy the file specified by the IFILE entry to the 64-bit Oracle home and edit the IFILE entry in the initialization parameter file to point to its new location.
If you have a password file that resides in the 32-bit Oracle home, then copy the password file to the 64-bit Oracle home. The default 32-bit password file is located in ORACLE_BASE\ORACLE_HOME\database\pwdSID.ora., where SID is your Oracle instance ID.
In the 64-bit Oracle home, add the _SYSTEM_TRIG_ENABLED = false parameter to the ORACLE_HOME\database\ORACLE_SID \init.ora file before changing the word size.
Remove this parameter from the initialization file after the word size change is complete.
See Also:
Oracle Database Upgrade Guide for more information on changing word size
Go to the 64-bit ORACLE_HOME\rdbms\admin directory from the command prompt.
Start SQL*Plus:
C:\> sqlplus /NOLOG
Connect to the database instance as SYSDBA:
SQL> CONNECT / AS SYSDBA;
Re-create the 64-bit control files using the CREATE CONTROLFILE command. Edit the trace file created in "Backing Up a 32-Bit Oracle Database" to change the paths to the datafiles, log files and control files to point to the Oracle home on the 64-bit computer. This creates the new control file in ORACLE_HOME\database.
Here is an example of a database named "orcl32" on a 32-bit computer migrating to "orcl64" on a 64-bit computer:
CREATE CONTROLFILE REUSE DATABASE "T1" NORESETLOGS NOARCHIVELOG
    MAXLOGFILES 32
    MAXLOGMEMBERS 2
    MAXDATAFILES 32
    MAXINSTANCES 16
    MAXLOGHISTORY 1815
LOGFILE
    GROUP 1 'C:\oracle\product\10.1.0\oradata\orcl64\REDO03.LOG' SIZE 1M,
    # was   'C:\oracle\product\10.1.0\oradata\orcl32\...LOG'
    # on the 32-bit computer
    GROUP 2 'C:\oracle\product\10.1.0\oradata\orcl64\REDO02.LOG' SIZE 1M,
    GROUP 3 'C:\oracle\product\10.1.0\oradata\orcl64\REDO01.LOG' SIZE 1M
DATAFILE
   'C:\oracle\product\10.1.0\oradata\orcl64\SYSTEM01.DBF',
    # was 'C:\oracle\product\10.1.0\oradata\orcl32\...DBF'
    # on the 32-bit computer
   'C:\oracle\product\10.1.0\oradata\orcl64\RBS01.DBF',
   'C:\oracle\product\10.1.0\oradata\orcl64\USERS01.DBF',
   'C:\oracle\product\10.1.0\oradata\orcl64\TEMP01.DBF',
   'C:\oracle\product\10.1.0\oradata\orcl64\TOOLS01.DBF',
   'C:\oracle\product\10.1.0\oradata\orcl64\INDX01.DBF',
   'C:\oracle\product\10.1.0\oradata\orcl64\DR01.DBF'
CHARACTER SET WE8ISO8859P1;
Alter the init file from the 32-bit computer to include the new control file generated in the preceding step.
Start the database in RESTRICT mode:
SQL> STARTUP RESTRICT;
You might need to use the PFILE option to specify the location of your initialization parameter file.
Set the system to spool results to a log file for later verification of success. For example:
SQL> SPOOL catoutw.log
Enter the following command to view the output of the script on-screen:
SQL> SET ECHO ON;
Recompile existing PL/SQL modules in the format required by the 64-bit Oracle9i database:
SQL> @utlirp.sql;
Turn off the spooling of script results to the log file:
SQL> SPOOL OFF;
Check the spool file and verify that the packages and procedures compiled successfully. Correct any problems you find in this file.
If you were viewing the output of catoutw.log on-screen, disable viewing now:
SQL> SET ECHO OFF;
Exit the RESTRICT database mode:
SQL> ALTER SYSTEM DISABLE RESTRICTED SESSION;
The word size of the 64-bit Oracle Database 10g Release 1 (10.1) database is changed. You can open the database for normal use.This is from the link

Migrate oracle database to Microsoft sql server 2005

Hi All,
I have to migrate production oracle database to Microsoft sql server 2005. Below are the details:
Oracle database version: 8.1.7.4
Platform : Aix
Kindly help me out

Well, the traditional way would be to dump out all your data from Oracle tables as comma delimited flat files and import into SQL server. Plenty of examples online, like this is one by Mark Powell: http://www.jlcomp.demon.co.uk/faq/flatfile.html
Or if you have the budget you could think about buying a data mapping tool like File-Aid
As mentioned by another poster, you will still need to figure out how to replace all your triggers, stored procedures, etc on your new platform of course.

Migrate oracle database to Amazon web services

Has anyone migrated an existing oracle database 11g or higher to the AWS Amazon web services ?
I don't believe we can use AWS's RDS Oracle service so we would have to customize it.
We are presently on a linux server and use Oracle Flexible Arch.
How do you tell/set AWS to replicate the file names and directory that oracle would use?
Appreciate any tips or documents that you can point me to.

Hi,

Migrating oracle databases to dbaas

here is a database environment with around 2700 oracle databases, we want to migrate 50 % of these database to DbaaS, what would be cost benefits, adavantages ? can I get some independent case studies apart from oracle supplied ones ? you help would be appreciated. thank you

Every single cloud vendor out there, selling whatever as a service, have failed to provide a 24x7 solution. All of them have had outage.
Even more worrisome, is these clouds being hacked - which makes your business data vulnerable. And there have been numerous hacks involving very large data sets being stolen. It is foolish to think that a cloud-based solution is 100% secure.
I would think twice about DBaaS on public clouds.
As for Oracle's DBaaS solution - that would be Exadata Database Machine. One of its major selling points is the consolidation of databases.

Migrate oracle database 9i to 11g

Hi,
i am in charge for migrating existing oracle 9i running on windows server 2003 to windows server 2008 with oracle 11g,, could you please advise me on the procedures needed to accomplish that.
Any help would be highly appreciated.
Basem

Hi Basem,
It is advisable to upgrade latest oracle version 11.2.0.3
The minimum required 9i version to 11.2.0.3 is 9.2.0.8
In case db version is less than 9.2.0.8, upgrade db to 9.2.0.8 using patch number 4547809
11.2.0.3 patch set is a full release. There is no need to install 11.2.0.1 software
First refer the upgrade path from below document
Oracle Database Upgrade Path Reference List (Doc ID 730365.1)
Note 419550.1 : Different Upgrade Methods For Upgrading Your Database
Note 837570.1 : Complete Checklist for Manual Upgrades to 11gR2
Note 870814.1 : Complete checklist to upgrade the database to 11gR2 using DBUA

startup the database as is (on drive e:\) and issue :
sqlplus / as sysdba
SQL> create pfile from spfile;you can then locate the pfile under $ORACLE_HOME/database, the name of the pfile will be init<SID>.ora
1. Copy the pfile to the new ORACLE_HOME on d:\
2. Change the ORACLE_HOME using SET ORACLE_HOME=<NEW HOME ON D:\>, from cmd window.
3. shutdown the instance.
4. copy the datafiles to there new location on D:\ (including the control files)
5. edit the PFILE and specify the new control files location (under D:\)
5. startup exclusive mount pfile=<Point to current PFILE>
4. Change datafiles names ;
alter database rename file '<OLD FILE PATH>' to '<NEW FILE PATH>';You can find the current location of the datafiles using :

Migrate Oracle Database between Exadata.

ways to migrate databases from one Exadata to other Exadata server.

Exact migration method applicable for your scenario will depends on many factors, DB size,available downtime, no downtime, source and target DB versions etc. Please do share the details around exact requirements. In general you can either go for logical migration or physical migration.
Logical migration methods-
1. Export import using data pump
2. Create table as select (CTAS)
3. Golden Gate etc.
Physical migration methods-
1. RMAN backup restore
2. Data Guard
3. ASM rebalance etc.
I would recommend to go thru following whitepaper to get more details. This talks about migration to exadata but most of the methods remain same even in exadata to exadata migration. In exa to exa migration, you get the benefit of connecting thru InfiniBand or using ZFS storage for quick sharing of backups etc. Moreover you don't need to worry about endian conversion.

High I/O wait observed in Linux based Oracle Database Server

Hi,
We have just migrated Oracle Database from Solaris Server to Linux VM [ESX] server.
We have observed that there is high I/O wait issues while database query is running on Linux VM, which was ideally zero in case of Solaris. The same Database was running with no i/o wait on solaris physical server.
In the same ref.I would like to below points.
- Recommendations for running Oracle on VM based Linux.
- Recommendations from ESX Host side
Please suggest.

The same Database was running with no i/o wait on solaris physical server.What did you expect? A virtualised I/O subsystem to respond and perform like a real one?
That would a very unrealistic expectation. And as comparisons go, as sensible as comparing the taste of an apple with the odour of the colour blue.
Forget about comparisons. Only marketing, sales and the idiot believe the cr@p that introducing several s/w layers between the the target (e.g. sector on spinning rust) and the destination (e.g. Oracle) makea the path between target and destination, faster.
To optimise the virtualised target, you need to make the path as short as possible. If your virtual disk is for example a file on a cooked file system on the host, then you are introducing the host's complete I/O layer for accessing that virtual drive. If your virtual disk is an actual (raw) partition or drive on the host, then path is faster - passing through the host kernel as direct I/O and bypassing the host's cache and file system drivers.
I suggest that when you setup your virtualised environment, you do proper stress testing of the various configurations of a virtualised I/O subsystem, using something like fio.
