I have used oracle 9i (9.2.0.1) version , i want to take incremental backup for a particular user... is it possible? if yes what is the actual command please tell me.

exp user/pass PARFILE=exp.par
In the exp.par

64bit OS から32bit OSへのexp/imp

Solaris 64bit にある ORACLE 9.2 からエクスポート(expコマンド)したものを、
RHEL 32bit にある　ORACLE 11gにインポート(impコマンド)しようと考えています。
64bit→32bitのexp/impは可能なのでしょうか？

64bit、32bitは関係ないですが(10g同士ですが、本番64bitから開発用32bitへのexp/impはよくやります)、
ORACLEのバージョン不一致の方がいろいろ制約がありますよ。
ただし、impの場合、下位バージョンから上位バージョンへは特に問題がなかったはずです。キャラクタセットが
違う場合は合わせないとダメとかは普通にありますが。
（細かい点は調べればすぐわかると思います）。

Is incremental backup supported using expdp in oracle 10.1.0.2

Dear All,
I heard that incremental backup is not supported in expdp of oracle 10.1.0.2.Here we have a databse which is running in noarchivelog mode.We are not allowed to shutdown the database coz it's live one.......
Our database is growing daily by 1 gb.Current expdp backup is running upto 4 hrs.Size is laready 40gb.So Is there any way where I can take incremental backup?
Please suggest me the type of backup.I have one more quetion if we can use rman backup in noarchive log mode?
Thanks,
Kris

Exp/Imp In Oracle 10g client

Hi All,
I want to take one schema export from Oracle 10g Client. I am in new Oracle 10g.
In oracle 9i, we can using exp/imp command for Export and Import from Client itself.
I heard about in Oracle 10g, we can use Expdb/Impdb in Server only. Is there any possibility to take exp/imp in Client also.
Pls help me...
Cheers,

To add up to expdb from oracle client
NETWORK_LINK
Default: none
Purpose
Enables an export from a (source) database identified by a valid database link. The data from the source database instance is written to a dump file set on the connected database instance.
Syntax and Description
NETWORK_LINK=source_database_link
The NETWORK_LINK parameter initiates an export using a database link. This means that the system to which the expdp client is connected contacts the source database referenced by the source_database_link, retrieves data from it, and writes the data to a dump file set back on the connected system.
The source_database_link provided must be the name of a database link to an available database. If the database on that instance does not already have a database link, you or your DBA must create one. For more information about the CREATE DATABASE LINK statement, see Oracle Database SQL Reference.
If the source database is read-only, then the user on the source database must have a locally managed tablespace assigned as the default temporary tablespace. Otherwise, the job will fail. For further details about this, see the information about creating locally managed temporary tablespaces in the Oracle Database Administrator's Guide.
Restrictions
When the NETWORK_LINK parameter is used in conjunction with the TABLES parameter, only whole tables can be exported (not partitions of tables).
The only types of database links supported by Data Pump Export are: public, fixed-user, and connected-user. Current-user database links are not supported.
Example
The following is an example of using the NETWORK_LINK parameter. The source_database_link would be replaced with the name of a valid database link that must already exist.
expdp hr/hr DIRECTORY=dpump_dir1 NETWORK_LINK=source_database_linkDUMPFILE=network_export.dmp LOGFILE=network_export.log

Perform Incremental Backup in Oracle 8i

Hi all,
I would much appreciate if anyone can provide me steps to do incremental back up using oracle 8i.

1) Normally, when we're talking about backups, we're talking about physical backups, i.e. backups of a database. Exports can be useful additions to a proper backup strategy, but should not be used in place of proper physical backups.
2) You cannot do an incremental export in a useful fashion. There is an "incremental export" option which will export the entire contents of an entire table if a single row changes, which may be useful if you have a schema with lots of large, totally static tables, but that's pretty rare.

Restore Tablespace incremental backup is not work as after reimage oracle

TheTablespace incremental backup Restore is not work as after reimage the oracle database or restore tablespace in standby machine(another machine) is not working .its working in the same machine without reimage .after reimage not working please clarify me ,
I need the solution as soon as please reply as soon as .
Commnads used:
This is the step is followed but i am getting backup or control file not found error.Its works i the application server is not reimaged ;
please give your valuable suggestion .
Product Used:oracle 11g in linux environmnet
1)Before taking backup get SCN number for restore.
Command applied: Select current_scn from v$database;
2)running Full backup of database
Command applied:
configure controlfile autobackup on;
backup database plus archivelog;
CROSSCHECK BACKUP;
exit;
3)Running level 0 incremental backup
Before taking backup get SCN number for restore.
Command applied:
BACKUP AS COMPRESSED BACKUPSET INCREMENTAL LEVEL 0 TAG ='WEEKLY' TABLESPACE TEST;

please calrfiy my following question:
1. After reimage(reinstall oracle database with application ).The aboove scenario is not working
2. After fullbackup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/) to repository because daily cleanup script will keep the data as sysdate -1 .
For fullbacckup we are currently copying entire (flash_recovery_area/dbname) database folder to repoistory.
3. after incremental backup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/..) to repository because daily cleanup script will keep the data as sysdate -1
For incremenatl backup currently we are copying (flash_recovery_area/dbname/backupset/<currentdate> and flash_recovery_area/dbname/autobackup/<currentdate>) folder to repoistory.
4.During restore we are copy entire things from repository to flash_recovery_area finaly apply the above mentioned restore command.
Tabelspace incremenatl restore is possible after reimage application server(fresh database)/another server with same database(standby machine) ....?
If we missing something in backup side please clarify me how to retore the tablespace incremental / level 0 tablespacae after reinstallion of server/another standby server.
Any information please let me know .I need the solution as soon as please reply as soon as .

Migrate oracle 9207 DB 8 TB size frm Solaris to AIX?dont want Exp/Imp

Hi Guys,PLz help
I want migrate 8TB oracle database from Solaris 8 to AIX 5.
In my last post on the same topic I was told to refer Metalink notes
291024.1,Note:77523.1,Note:277650.1
acc to these notes 'EXPORT/IMPORT IS THE ONLY OPTION TO MIGRATE FROM SOLARIS TO AIX'.
I was not convinced as In http://dba.ipbhost.com/index.php?showtopic=9523
I read
"As both solaris and AIX are UNIX O/S, cloning the DB is also possible from source box to target box"
Also
whats the role of "If the endianness is the same"??????
Can you guys plz comment on this again.....as I'm really confused because exp/imp of 8TB
is going to take half of my life :)
PLz tell in any other option in 9.2.0.7?If we have
Thanx

You can do
SELECT PLATFORM_NAME, ENDIAN_FORMAT
FROM V$TRANSPORTABLE_PLATFORMto check endianness of different platform.
-- Note, the view is only on 10g and above.
datafiles from different endian format can't be directly copied over and use. On 10g you have option to use RMAN convert endianness.
with that said, since Solaris and AIX are all big engianness. That means you can directly copy datafiles over and clone database without using exp/imp.
this article has a list of how to clone

Oracle incremental backup too slow

Hello All,
Oracle 9.2.0.7
Windows 2003 server
Database size around 200 GB.
Daily archive generation may be around 40. Archive log size 200 MB.
We have implemented the below backup strategy
1. weekly once full incremental level 0 backup(differential).
2. Daily incremental level 1 backup(differential).
Daily incremental backup size will be around 1 GB.
Now we are facing a problem because of the incremental backup. The incremental backup is taking more than 1 hour time to complete. So we are not able to run it in the production time.its a 24/7 production database.
Please advice how to reduce the incremental backup time ?
Is there any options like what we have in 10g Block change tracking. please advice..
TIA,

Step by Step EXP / IMP database from Oracle 9i to Oracle 11g

Please help on the captioned where I did the below
1. Use EXP to export the database from a Oracle9i database (O9_DB) OLD_Windows2003_SERVER
2. Install the Oracle 11g (default service name is ORCL) to a new Windows 2003 server and use the IMP to import the O9_DB, however, I need to create the same physical path as the OLD_Windows2003_SERVER (e.g E:\Oralce_9i\Ordata\) in order to complete the IMP
3. I can launch the SQL Developer and obtain the records count of evey tables being imported
However, is there any best / proper way to do the EXP/IMP, the ideal outcome would be
1. Create a new namespace say (OLDDB) which same as the Oracle9i database name so maybe I don't need to modify much on the application side to point to the new database ?
2. IMP the OLDDB to the new namespace OLDDB
Thanks in advance

Hello,
If you create the new Database on a new Server, you could keep the same name for the Database.
To switch from the old Database to the new one, you'll have to change the hostname on the "tnsnames.ora" or in any configuration file which define the database connexion.
About the best way to do the Export/Import, you may have some details on the link below:
http://download.oracle.com/docs/cd/E11882_01/server.112/e10819/expimp.htm#i262317
Else, why do you intend to stay on a Windows 2003 Server, why not moving to Windows 2008 ?
NB: Oracle *11.1* is certified on Windows 2008 and Oracle *11.2* is certified on Windows 2008 R2.
Hope this help.
Best regards,
Jean-Valentin

Full Database Exp & Imp

Hi,
I am trying to Exp & Imp a full database. I am working on Oracle 9i & 10g on Solaris 9. I am not using Data Pump. Can anyone please help me with the following:
1. I am performing the full export using SYSTEM user.
1.a Does a Full export include (or backups up) the DATA DICTIONARY of the database?
1.b Does a Full export include the backup of SYS and SYSTEM objects?
I am using the following command to export
exp system/system@testdb file=$HOME/testdbfullexp.dmp full=y statistics=none
I have tried importing the FULL export to another database and i did see that SYS and SYSTEM objects were also being imported ( got some errors regarding constraints and inconsistencies).
I would like to ask like what are the ideal steps to follow to copy a database from DB1 to DB2 using EXP and IMP
Any information will be of a great help
Thanks,
Harris.

1 a) No, as the data dictionary will be automagicall recreated by implicit SQL.
This means any non dictionary objects under SYS will be lost
1 b) as above. SYSTEM however is a normal user.
any %SYS user will NOT be exported (CTXSYS, MDSYS, etc)
On import of SYSTEM there will be always errors, as SYSTEM is non-empty after initial database creation.

Refresh using exp/imp

Hi All,
I need to refresh one of my development database using exp/imp utility,i did refreshing using the copy datafiles but new to this ,i have gone thru this forum and did some search on google too but the part that am not getting is suppose my development db already created with same tablespaces name and size and containes every schema as that of source and has data in it which is refreshed earlier, so do i need to wipe out everything and do it right from scratch(create db,tablespace,users) or just wipe out tables and import with (ignore=Y) .Any feedback would be apperciated.
Thanks

Hi,
 
>> do i need to wipe out everything and do it right from
scratch(create db,tablespace,users)
 
Well you have choices, and you can do whatever you want,
but there are some “best practices”. I’m assuming that you are copying your
PROD database into DEV (a great practice to have a full-sized production system
the TEST and DEV):
 
- You can restore PROD into TEST using RMAN.
 
- You can use the
<a style="color: blue; text-decoration: underline; text-underline: single" href="http://download-east.oracle.com/docs/html/B16227_02/oui7_cloning.htm">
Oracle Universal Installer</a> to clone a database.
 
- You can “<a style="color: blue; text-decoration: underline; text-underline: single" href="oracle_tips_db_copy.htm">clone
the whole database</a>”, moving the current datafiles and recreating the
instance
 
- You can export from PROD, truncate the tables in DEV
(after a backup) and import IGNORE=Y. This can be very slow, especially for a
large database. However, there are some

tips to speed-up imports</a>.
