Backup / Export database

What are the different purposes of "Backup" and "Export" database in Oracle DBMS ???
And about the meaning, they are same or different ???
Thanks !
Carollynn.

As I can see it, an export does not really give you the same possibilities as a backup (although I see the block verification iusse, I use dbverify regularily).
The export can be used in two ways. Re-import single tables if e.g. a user wrote wrong data into it. But beware of referential integrity. Then you can import the whole schema/database into a NEW database and you will have a copy of your database at the time the export was taken. You have to make sure, CONSISTENT=Y is set and that, as a general precaution, nobody is connected to the database itself. Otherwise, you might set yourself up for data integrity problems.
Full (hot) backups allow to repair the current instance to a certain point in time. You do not change the instance, you repair it. If done right, you can bring your database back to the point of failure time. Also, you can repair singe tablespaces, ... .
We use both exports for creating copies of databases (e.g. for testing) and for migration from e.g. Oracle 7.3.3 to 8.1.5.
Taking daily hot backups is our main backup mechanism.

Backup and database export fails

Now that I've got the database up and running, I'd like to export and/or backup the database. After relaying (I've got a German version of Oracle, so I have to guess what the original terminology might be) the job, it is listed as 'unsucccessful' in the job history. The error code is "VNI-2015 Fehler in der Berechtigungspr|fung" (meaning 'error in authorization check'). The preferred ID-data should be the correct ones.
Helpless again,
Claus.

Greg,
You need to push planning application into maintenance mode or stop planning server -- to stop users logging/entering data through forms
If you have single planning app or all apps can go down during nightly process then just stop planning server by calling stopplanning.cmd( not sure about file name)
after you nightly process is done call startplanning.cmd
If you have multiple applications and only a subset of them needs to be under maintenance mode
then you need to change few values in your application Relational repository ( its not recommended by Oracle)
LOGIN_LEVEL='0' - For all Users
LOGIN_LEVEL='2' - For Administrators
you need to change Login_level value to '2' to move app into maintenance mode..
this link will give you a better idea http://www.orahyplabs.com/2011/02/place-planning-under-maintenance-mode.html
just add above mentioned steps based on your requirement

1005000 &1005029 Essbase Error - MaxL Export database

Hi, I'm trying to export data in a MaxL command called by a Perl program (automated batch process) using the following command: export database StgAll.StgAll level0 data in columns to data_file 'H:/Export_folder_server09/StgALL_export_server.txtThe Perl program is called from the server 04 and it export a database on the server 09. The ?H:/Export_folder_server09/? directory is mapped ?network driver? on the server 04. I get the following Error message: Executing [export database StgAll.StgAll level0 data in columns to data_file 'H:/Export_folder_server09/StgALL_export_server.txt']... 1005029 - Parallel export enabled: Number of export threads [1] 1005000 - Ascii Backup: Failed to open [H:/Export_folder_server09/StgALL_export_server.txt]. 9 - Essbase error encountered: [GetProcessState] [1005000] 51 - MaxL execution failedWhat am I doing wrong?Someone can help me ?Thanks in advance, Manon

I'm not certain if thi sis your problem, but I believe it has something to do with the way you are using / marks in your directory path.Take a look at this excerpt from the MaxL tech doc. I hope this helps you.Use of backslashesIgnored unless preceded by another backslash (the escape character). Must use single quotation marks around the token containing the two backslashes.Example: create or replace group 'R\\D';Result: Group R\D is created.Example (Windows): export database sample.basic using report_file 'Essbase\\App\\Sample\\Basic\\asym.rep' to data_file 'c:\\home\\month2.rpt'; Result: The Windows file paths are interpreted correctly as Essbase\App\Sample\Basic\asym.rep and c:\home\month2.rpt.

Backup the database without shuting down the database

Hello All,
Just want to ask if any one can tell me if it is possible to backup the database without shutting it down
When can you do so if it is possible?

A hot (or on-line) backup is a backup performed while the database is open and available for use (read and write activity). Except for Oracle exports, one can only do on-line backups when the database is ARCHIVELOG mode.

How can I export database incremental?

I want export database for backup.
how can i export database incremental?

What Oracle version are you using ?
The following is from 8.1.7 documentation about INCTYPE parameter :
Incremental, Cumulative, and Complete Exports
Important: Incremental, cumulative, and complete Exports are obsolete features that will be phased out in a subsequent release. You should begin now to migrate to Oracle's Backup and Recovery Manager for database backups.

Import & export database

hi
iam a vovice user & working on tables can you tell me detailed solution that how can i export database from my computer & how can i import that database on another computer

Hi...
i am a vovice user & working on tables can you tell me detailed solution that how can i export database from my computer & how can i import that database on another computerThere are lots of documents available on this topic.FOr any oracle related document you can go to [http://tahiti.oracle.com/].
What is the oracle version you are using.If on 10g or above use expdp.
Export can be done
1. Object level 2. Schema level 3. Full 4.Tablespace level
I would prefer instead of taking a full export backup and importing it into another database, take the export of the required application schemas and import it into the target database.

DAG - Backup failing on 1 DB only with error - The Microsoft Exchange Replication service VSS Writer instance ID failed with error code 80070020 when preparing for a backup of database 'DB012'

Hi Board,
i´ve search across the board, technet and symantec sites but did not found a hint about my problem.
we drive a 2 node DAG (Location1-Ex1-mb1
Location2-exc1-mb1), on SP2 RU4 patchlevel with 40 Databases.
Since some time the backup of one - and only one DB - is failing with these events, logged on the Mailboxserver on which the passive DB is hosted.

Symatec suggests within http://www.symantec.com/business/support/index?page=content&id=TECH184095
to restart the MS Exchange Replication Service – BUT the mentioned eventID
8229 isn´t present on any of the both Mailboxservers.
The affected Database is active on Location2-Exc1-Mb1 Server and in an overall healthy state. I found during my research, that below Location2-Exc1-Mb1 Server, there are not removed shadow copies present!
This confuses me, since all Backups are normally taken from the passive copy of a Database.
So my questions to the board are:
* Does anyone is facing similar issues?
* Can someone explain why snapshots are present on the Mailboxserver hosting the Active Database, whilst the errors are logged on the passive one?
-          * Does someone know the conditions, why shadows copies remain and
aren´t removed in a proper manner?
What can cause the circumstance, that only 1 DB is facing such issues?
Any suggestion is welcome!

Hi Lenora,
I´ve encreases VSS / Exchange Backup Log levels to expert, before starting
those things i´ve all tried now:
- Backup from passive DB (forced within Symantec Backup Exec)
- Backup from active DB (forced within Symantec Backup Exec)
- Backup from passive DB without GRT enabled (forced within Symantec Backup Exec)
- Backup from active DB without GRT enabled(forced within Symantec Backup Exec)
All those attempts failed.
But brought some more details - the backup against the active DB states, that there is still a backup in progress and therefore this backup is cancelled by VSS.
The Solution was, that i´ve needed to restart the Exchange Replication Service on the Mailbox Server hosting the passive DB.
Backups are working again on all DBs!
THX for your replys.
Best regards
Markus

How to take backup of database on external hard disk

Hi Team,
We have a server with three instances SOX,GRC and SM2. We have attached
a external hard disk to take backup of database. While taking backup of
any database it gives error as attached. We can take backup of
transaction log on server's disk but not on external disk. Kindly have
a look on attached error and advice us.We are taking backup at sql
server level.
version: SQL SERVER 2005 64 bit
Regards,
Digambar

Hi Markus,
>You can´t backup a 210 GB database on a 200 GB disk...
We learn a lot every day on these Expert Forums !
In fact, it could even be possible if it's the database enveloppe which is 210 GB and the actual data is less than 200 GB !
I dare to hope that it's not a production system which is backed up with an external disk...
Regards,
Olivier

I got error when I export database ORACLE 9i from solaris 9.

Export database in quiet mode

I'm trying to export database (or part of it) via exp utility. Exp utility should be called from command file or from another process (on windows). If something goes wrong (for example user name or password is not correct) exp pauses it's execution and trying to ask user what to do (for example enter valid user name). This is the problem. I want that exp just finish it's execution without asking any input from user. It is possible at all?
I have read exp's documentation and not found any command line keys which could run exp in non-interactive mode.

My export command follows:
D:\Users\ender>C:\Oracle\Ora102g\bin\exp.exe hr/hr@ORCL102G FULL=Y FILE='D:\Users\ender\My Documents
\hr.dmp' LOG='D:\Users\ender\My Documents\hr.log'

How to backup a database in noarchivelog

My database is in NOARCHIVELOG.
I can open rman
which command can i use to backup my database in this mode.
is there anything i need to configure before it backups in this mode.

why you dont need to turn on the archivelog?
CONFIGURE RETENTION POLICY TO REDUNDANCY 1
how many days back you are responsible to revert back the database?Someday It may be asked to you restore the some days before dataabase backup, before that raising the question ,raise the question to mangment personnel how many days back will i be responsible to restore the database,if they give you 7 days then make sure yours disk space can accomodate 7 days backup if not then ask them to arrange space for disk if they give alternate tape cartrdige then tell them that x hours will take to restore the database in disaster recovery scenario cause tape cartridge data restoration takes time.
No archive mode is yours decision then before doing it aware managment personnel that i can only restored the last good backup data,good backup does not mean last backup,last backup may be corrupt ,last good backup is the backup which you can restore then you will be able to restore only till last good backup,with archived enabled you will have chance to recover till before crash but with no archivelog there is only one option recovery till last good backup.

So the said package of Sys has issues. Is this database being upgraded recently and thus is having some invalid packages?

Urgent- Exporting database tables

Hi There,
I am using Oracle 8.0.6. I want export a table from one server to another.(both are unix machines). How can I do it?
Thanx in advance

If a table is samll, then I would recommend you to create a dblink between them and use copy command to copy the table from one db to another.
Export:
exp system/password file=exp.dmp log=exp.dmp tables=username.table_name direct=y statistics=none

Do you have same user exists in both databases? Do you have same tablespaces exists on both databases?
