Oracle 10g database backup & recovery

Hi,
How can i take backup of our oracle 10g database by copy its physical database file and how can i restore them from these files.
is any Strategy other then RMAN??
Regards

Can you afford to shutdown the database? If yes, do a cold backup.
1. Do a clean "shutdown immediate"
2. Copy All the Datafiles, Controlfile, Redo Log Files, Spfile/Init files using Operating System command to a required location
When you want to recover
Just copy the files back to the original destinations and statup the database. But ou hav eto know that if you copied your file by 11:00 on 25/08/06. And you loose your database on 27/08/06, you can only recover back to 25/08/06.
If you cannot afford to shut down your database or loose data, best to run your database in Archivelog Mode. Schedule and use RMAN to do a hot backup at specified time automatically. The advantage is that you do not have to shutdown your database to get a consistent backup like teh cold backup.

How to get the oracle 10g database backup.

Hi,
i have installed oracle 10g.i need to get the back up of db.
i have search so many sites.i didn't get much information.
some guys tells we go to installed directory in that run"RAMNS".
i am following in the process.after run the rams which commands
i have to used to get the db back up.
C:\Oracle\app\oracle\product\10.2.0\server\BIN\RAMNS
RAMNS>...(here is the prob which commands i have to used)
i have seen another way solution is you can use "imp" and "exp" present in BIN to take back up.(how to follow this)
please help me,

Would suggest you read the docs on backup, restore. if you cannot restore you db, you are in trouble. read it and understand it well.
Summary:
For 10g, you have rman, imp/exp and datapump import/export (replaces imp/exp).
For very simple backups where you have windows you can shut down, run a cold backup. shutdown the database, copy the database files, and startup. i also take copies of the current pfile and anything else important to restore the database with. we copy the files to a dedicated backup file system, which go to tap, e.
That will give you a simple option to restore.
For prod databases, you typically want archive mode on which means you can run hot or online backups. just remember you have to have the archive logs generated during the hot backup. you now also have the ability to do a point in time restore.
Exp or datapump exp can be used for metadata exports, full exports or partial (schema, table, etc) as needed. i typically run a cold or hot plus an export for redundacy and restore options, but db size will change how you back things up.
You can find plenty of scripts to automate these. just understand how the scripts work and understand the process itself. if not, you will have trouble restoring when it is needed the most.
Rman is also a good option with the latest releases.

Can cold backup be taken for ASM managed oracle 10g databases

Can cold backup be taken for ASM managed oracle 10g databases
Pls help

do we still need to take cold backupYou need to take backup. Hot or cold depends on how your DB is running (archivelog or not).
Will we have file permisions for copyng Use RMAN and don't worry about that.

Exporting of files in oracle 10g database

hey friends,
I installed Oracle 10g Database server on Windows XP,when i tried to take the backup through "Export to Files".I got this error.
I have added Administrator in "Login as Batch JOb" and has given administrator along with the password in host credentials.
I explain the procedure.I Login as Sys as SysOper as Oracle does not allow to take backup as sysdba.
I created the job and also given the right path for the backup but some how it fails then i check the log and i find the following output.
Output Log

Doc ID: Note:10767.1
Subject: How to perform FULL System Export/Imports
Type: BULLETIN
Status: PUBLISHED
Content Type: TEXT/X-HTML
Creation Date: 18-APR-1994
Last Revision Date: 30-AUG-2002
Purpose
This article highlights some important points to consider when performing
a Full System Export and Import.
Scope and Application
It is intended to assist users performing FULL System Exports and Imports.
A Full System Export and Import is a useful way to replicate or clean up
a database. Please note the following guidelines when performing a Full
System Export and Import:
1. When performing the import, ensure you are pointing at the correct
instance. Always check values for the SID and two task driver before
proceeding.
*Note: On Unix systems, just entering a sub-shell, such as using
C-shell, can change the database that the import would work
against.
2. When possible, it is advisable to take a physical copy of the
exported database and the database you intend to import into before
starting the import. This ensures any mistakes are reversible.
3. NEVER run a FULL SYSTEM IMPORT on a machine that has more than one
database UNLESS you are 100% sure all tablespaces have been
pre-created. A full import will create any undefined tablespaces
using the same datafile names as the exported database. There are
situations where this is very dangerous:
-> If the datafiles belong to ANY other database, they will be
CORRUPTED. This is especially true if the exported database is
on the same machine, because its datafiles will be re-used by
the database you are importing into.
-> If the datafiles have names that clash with existing operating
system files.
4. When exporting, it is advisable to also produce a report showing
information you may need before / after the import:
-> List the tablespaces and datafiles
-> List the rollback segments
-> List a count, by user, of each object type such as tables,
indexes, etc.
This enables you to ensure that tablespaces have been pre-created
and to check the success of the import after it is complete.
5. If you are creating a completely new database from an export, remember
to create an extra rollback segment in SYSTEM, and make this available
in the init.ora file before proceeding with the import.
6. There are some versions of export that do not retain sequence numbers
correctly. It is advisable to select next_value for each sequence
after the export so that these can be checked after import.
Following these guidelines will help you to avoid major problems.

Subject: How To Copy an Oracle Database To Another Machine
Type: HOWTO
Status: PUBLISHED
Content Type: TEXT/X-HTML
Creation Date: 12-OCT-2001
Last Revision Date: 01-OCT-2003
goal: How to copy an Oracle database to another machine
fact: Oracle Server - Enterprise Edition
fix:
Pre-requisites: The copy is between 2 machines, both have to be on the same OS
and have to have exactly the same database version installed.
1. Make sure the database you want to copy was closed with a SHUTDOWN IMMEDIATE,
SHUTDOWN NORMAL or SHUTDOWN TRANSACTIONAL.
2. Copy init.ora and control files to create instance and be able to go in
mount mode. Check the init.ora for the locations where the controlfiles have
to be, if those locations are not valid on the machine put the control files on
different places and adjust the init.ora accordingly.
3.a. Copy the datafiles (all of them).
b. Copy the redo-logfiles (all of them).
4.a. (Unix only) Set the environment variables:
ORACLE_SID - set to the database name you wish to create
ORACLE_HOME - set to full pathname of the Oracle system home directory
PATH - needs to include $ORACLE_HOME/bin
b. (NT/2000 only) Do 'set ORACLE_SID=<SID>'
Use oradim to create the service for the instance. For more information
on oradim please refer to (the part that refers to creating a new instance):
Note:68720.1 Creating a new 7.3, 8.0, 8.1 Instance/Database
5. Use servermanager (check the name to use for your version of oracle) or
sqlplus (version 9i and above) to startup the database in mount mode.
Do
CONNECT INTERNAL/<PASSWORD>
then
STARTUP MOUNT
Then do a rename of the copied datafiles if they are not in the same path as on
the other machine. For all the files that are in the result of the query:
SELECT NAME FROM V$DATAFILE;
do
ALTER DATABASE RENAME FILE '<oldfullpath>\<filename>' to <
newfullpath>\<filename>';
6. Query the datadictionary for the old location of the redolog files using:
SELECT MEMBER FROM V$LOGFILE;
If the new place is not the same as the old do:
ALTER DATABASE RENAME FILE '<oldfullpath>\<redologfilename>' to &
lt;newfullpath>\<redologfilename>';
7. Now open the database:
ALTER DATBASE OPEN;

Restore and recover Oracle 10g database from tape.

I have a very basic question for restore and recover Oracle 10g database. Our envirnment settings are:
Oracle 10g on Unix, daily database and archivelog backup to Vista NetBackup server. Retention policy is 2. Old backup files are copied from NetBackup server to the tape for record keeping.
I want to restore a database to a point in time. Because our retention policy is setup to 2. The backup files I need have been copied to the tape. So I should ask SYSTEM ADMIN to copy the backup files back to NetBackup server disk or I can ask him to copy backup files to the Unix server that host my Oracle 10g database. Then I can use Rman to do restore and recover. Is this doable? I know normal procedure is to copy backup files I need back to NetBackup server disk, not directly back to database server. Please put your comments here as early as better. I do appreciate your kind help.

Please put your comments here as early as better. I do appreciate your kind help.For sure it is double work, To copy backup files on UNIX host.
Are you using catalog or nocatalog?
If the backup information is out of retention, Catalog them again also in netbackup.
So that you can able to restore database directly without copying those files to host.

Error starting up Oracle 10g database.

Hi,
(I had shutdown my database by "shutdown abort")
Now i'm getting the following error while trying to startup Oracle 10g database version :- 10.2.0.1.0.
SQL> startup nomount
ORA-07345: The datafile name must not contain the string '..'.
I get the same error even for startup/ startup mount
currently i'm using only pfile for startup as there is no spfile in dbs directory.

Hi Kuljeet,
This is a very strange error, i know, controlfile contains are not read in "no mount" state of database... still i'm getting the error.
The contents of my pfile are as follows :-

Hi All,
I am trying to face some problem to install oracle 10g database on windows 2003 server with service pack 2. Once I start to installation it give me an error "Error in writing to directory 'c:\documents and settings\administrator\local settings\temp\orainstall2004xxx'. Please ensure that this directory is writable and has at least 45MB of disk space. Installation cannot continue"
I double-insured that there is enough disk-space and I am also in the Administrators-Group.
Please guide me for the above problem although I have done oracle 9i database installation with the same configuration.

Installation of Oracle 10g Database on Windows Vista Home Basic

Hi All,
I'm confused about the possibility of installing Oracle 10g Database Server in Windows Home Basic Operating System with Service Pack 1. Please help me out with a confirmation.
Thanks in advance
Prasanth

Hi Prasanth
Yes that should be possible but is it a production database or just a test database.
you can always control that in metalink if it is supported, I don't believe it is.
Read that documentation to perform the installation.

I did this right after I restarted my computer.
When I use the Enterprise Manager at:

I get for ORCL:

Seems that I can never get the database started properly?! When I press the Startup/Shutdown button I get:

This is the correct current database status, although it doesnot match the current status in the sitemap page
What does this mean? Do you think this may contain the clue to the answer to this problem?
When I restart the Database I get the same status: unavailable.
I need your help to resolve this problem. The alternative is to revert back to Oracle 9i DB Server. Thank you in advance.

We are getting ¿ stored into our Oracle 10g database (Microsoft fault)

We are getting ¿ stored into our Oracle 10g database that is using WE8ISO8859P1 character set.
Problem is caused by the following:
Microsoft released software (in particularly MS Word) before considering any ANSI or ISO standard (although they claimed so).
At that time of pioneering graphical interface - they were the standard. Since then things changed. Microsoft initially targeted US marked, however very soon they wanted to expanded to Europe. For that they needed to get standardized character set instead of one initially being in use. Microsoft re-mapped character set in newer applications using Windows-1252 character set which is compatible with ISO-8851-1 (we are using in our Java Web applications). That cleared obstacles to forward on European market, where extended characters are necessary (like in French, Dutch, German languages...)
What happened with the initial character codes before Microsoft agreed with ISO to standardize characters? Well - Nothing.
So what are the consequences of that?
If we are using Microsoft Word document in conjunction with one of the oldest character set (universe) the ice-age character mapping is still there. So when we "cut and paste" the content to another application, characters sets are not mapped anymore. Especially French language "is sensitive to this" The Microsoft character set in Word decimally coded 146 ( ' ) is very often used in French.
Therefore if the text is generated in MS Word using old character mapping (universe) which we do, and using method of "cutting and paste" we are mismatching character set interpreted by other, newer applications.
Initially in the MS words (apostrophe) ' had code 191; then later after implementing Windows 1252 character set being moved to code 146 in accordance to ISO. Well ISO threat character coded 191 as ¿. So if you are using MS Word universe character set, ' looks like ' but in newer applications or ISO compatible applications it looks like ¿.
Can anyone provide me with periodically cleanup routines that replace garbled characters entered by Microsoft applications into Oracle database ?
Thanks
Brendon
