Backup Oracle Database On 24x7 System

Dear Kamran
First sorry my English.
I am a beginner of oracle 10g and have a problem please help (Consult) me. If you are accept it
My problem is a :
Two oracle server with RAC (Clustering) and one external oracle server (BACKUP ORACLE SERVER) on the this network without RAC (Clustering) on the RHEL 4.7
How to synchronize third oracle server’s database with RAC oracle servers. Becouse of if RAC Oracle servers down or technical corruption change corrupted server.
Or other flexible solution tell me (how to do it)

you can make the third oracle server as a physical standby database to RAC setup. for more information, read oracle doc "Dataguard basics and administration" from http://tahiti.oracle.com
as other option, you can schedule a refresh job from RAC setup to third database server.

How to install two oracle database on one system

i want to install two oracle databases on single system how it is possible
how i can manager oracle home and is this possible to install two different version of oracle in single home or single system forexample oracle 9 and oracle 8 .
A.R

Hi,
yes, u can have more databases on a single machine and they can be of different versions.
You have to use and initialize the correct ORACLE_HOME to create the DB of the version U use.
For ex, u have 2 homes:
C:\Oracle\Ora817 8i home and C:\Oracle\ora920 9i home
Normally, using OFA, imagine that You want create 2 db, TEST_8I for 8i home and TEST_9I for the 9i home, You shold have:
C:\Oracle\Admin\TEST_8I\<<OFA DIRS>> and C:\Oracle\Oradata\TEST_8I for 8i DB adn C:\Oracle\Admin\TEST_9I\<<OFA DIRS>> and C:\Oracle\Oradata\TEST_9I for the 9i version.
It is important, when You create the DB, that u use the executables of C:\Oracle\Ora817\bin to create 8i db and C:\Oracle\Ora920\bin for the 9i one.
Then U can use the 9i listener to manage both instances
Hope this helps

How to backup Oracle Database Single Instance using RMAN

Folks,
Hello. I am using Oracle Database Server 11gR1 with Operating System Oracle Linux 5.10.
I understand how to backup database instance in SQL Server with Windows. But don't really understand how to backup database instance in Oracle with Linux.
I have done Cold backup and Hot backup for the database instance HRCS90 but both get the same error message.
Cold backup is below:
SQL> startup

While the database instance HRCS90 is startup, I do hot backup using the same commands and get the same error message with above cold backup.
My question is:
Can any folk tell me the specific steps (command by command) to backup a single database instance in Oracle using RMAN ?
Thanks.

Folks,
Hello. Thanks a lot for replying. My database instance named HRCS90 is going to be backed up. My backup directory is /backup_Database_Instance_HRCS90.
If database in open state, we must back up in archive log. If database in mount state but not open, we can back up in noarchive log.
I have tried to back up HRCS90 in archive and noarchive log when database in mount state but not open as below:
SQL>startup mount;
SQL>exit

RMAN>connect target;

Can't mount oracle database on linux system

This is same as previous posting just added
e-mail and username info fo forum posting.
I am not able to mount an Oracle database.
I am new to Oracle and am working on an Oracle8i installation on an
Intel Linux Suse 6.3 platform. I am using only one harddrive and am
not using the 4 mount points as mentioned for efficiecy purposes in
the Oracle documentation..I am using the installation cd from Oracle8i
for Linux Starter Kit by Oracle Press. If anyone has this book they
can refer to pages 41-44 for the examples I followed.
As sysdba in sqplplus using the STARTUP command I can not Mount the
database -step 2 of the 3 stage process (Start, Mount and Open the
database) of opening an Oracle database.
I show the errors I encountered when I did the first 2 of the 3 steps
in the step-by-step mode (STARTUP NOMOUNT pfile=, ALTER DATABASE
MOUNT) in the sqlplus session and alert log respectively with startup
nomount and alter database mount for this sqlplus session.
Additionally I show the init.ora file lines referring to control file
which seem to be referred to by the sqlplus error messages and the
alert.log file. Perhaps some can give me some advice as what I can try
to fix this problem.
At the end of this e-mail I added several questions I had in regard to the control
files. Any help is appreciated.
Well, here are the sqlplus session results and its alert.log file:

2) On page 100 in the book Oracle 8i A Beginners's
by Oracle Press mention is made of a
CREATE CONTROLFILE command that can under
circumstances be used to re-create a control-file.
but that is all that is said about it. Perhaps
you might know something more about it.
3) Would you recommend any good text for
Oracle DBA's, especially for the problem of the sort
that I am encountering?

It's probably not supported on RHEL5/Centos5/etc., but...
You can get the installer to function using the following steps:
- extract the cal_linux_*.tar.gz, and cd into the OracleCalendar_inst directory
In there is the actual installer, cal_linux.
- the cal_linux is shell script wrapped around some binary blobs. The installer's
problem is that Oracle is setting the LD_ASSUME_KERNEL=2.2.5 environment
variable, which is a mistake on RHEL5. You need to make it not set that variable,
but you need to do so in a way that the size of the shell script does not change at all,
and none of the binary blobs are impacted.
- the approach I took was
mv cal_linux cal_linux.BAK
sed -e 's/LD_ASSUME_KERNEL=2.2.5/LD_ASSUME_KERNEL= /g' < cal_linux.BAK > cal_linux
chmod a+rx cal_linux
cal_linux -i gui
Note: you must have exactly 5 spaces in the substitution part of the sed command, because you're replacing 5 characters (2.2.5), and the size of the shell script must not change.
If you do that, the installer should run (one warning from awk still) and you should be able to install the product.

Oracle Databases and Storage Systems like HP EVA

Hi everybody,
are there generel advantages or disadvantages using such storage systems?
I would be happy if somebody could talk about his experience using such systems.
Is there better/less performance with Oracle Databases? Better/less Security for my Data instead of using a local raid 5/1+0 for example? Or anything else I should now before using such a storage system.
What type of storage are you using? What type of disks would be the best (scsi/fata) ?
Please talk with me a little bit about your experience with storage systems and Oracle Databases ;-)
Thank you

Greate to meet another DBA in forum.The big problem we will face is SQL Tune.
Nothing much Diffnt supporting SAP.SAP PRovided some ready made tools to monitor and to solve.Reg tuning still we can follow same methoda but with approval from SAP or by ref SAP notes.Which u can find at service market place.
You can find some PDfs in sap market place and sdn.Which are ex'ly for DBas.
Reg Growth rate you can have a look on sap transactions and there are some notes also.I dont think there is specific Book or Doc which will say Dos and donts.
Performance we used to follow same methoda as a Dbas with ref of sap notes and support for any side effects.
let me know if are in need of any specific info

Backup Oracle Database whilst online

Guys looking for some help, I have an Oracle database that must run 24hours a day but I need to be able to back this database up daily, from what I understand I have to make the database run in archive log mode to be able to perform a hot backup.
I have found out that currently my database is in noarchive log mode
Can someone help me with the commands to put the database is achivelog mode
Then can you help me with the command to backup the database using RMAN I have read some documentation do I need to just issue the backup database command or do I need to backup the archive logs files as well ?

Do you want to teach me lesson ? I'm working with Oracle database since 1988, and I'm using RMAN since version 8.0 (15 years ago, or so).
And please read the link I posted above.
1) ... At lease two redo logs destination is recommended so that one redolog destination is keep working while other is filled up or vice versa.
And you think I don't know that ? And that's not multiplexing.
2) Catalog database is optional but it is recommended.
It's absolutely not needed, and I consider it just and overhead (another database to manage and to synchronize).
3) You need to setup archivelog retention policy so that it cleans up from LOG destination after certain period of time.
You use DELETE INPUT option in your script, but it looks like you don't know what it means.
Please follow oracle documentation for best practice .
Again, are you teaching me lesson ? Oracle documentation is my bible.
Backup is very important for a DBA so you need to set up precisely so that you can recover the database during disaster
Backup is very important for a DBA ? What a news !! About disaster recovery, at your #1 you said "redo logs are very important to restore database" : or we mean something different for "disaster recovery", or you are totally wrong.

ShadowProtect to backup Oracle Databases

Hi to all
I would like to hear from anyone if you are using ShadowProtect to backup your Oracle databases.
What are your experiences and the pros and cons in using ShadowProtect as the one and only backup/recovery tools for Oracle databases?
Can the potential of ShadowProtect replaces the commonly use Oracle backup/recovery tools?
The reason why I raise this question is because my boss has the idea that ShadowProtect is THE best backup/recovery tools. Personally I don't think so, because there can be cases where we only need to recover the database and not the whole OS. Thus need to hear more from you guys.
Thanks.
Edited by: moslee on Mar 22, 2013 2:24 AM

Hey Moslee,
You should definitely be testing your Oracle database recovery plan quarterly. If you're not even testing it annually that would be what really scares me the most. Testing should show you what you can and cannot get out of your backup and recovery software. Everything else being equal, please please please test your backup and recovery plan and do it often.
As for ShadowProtect, one of the nice things about this backup solution is that it's an image-based backup which means that it will quiesce the Oracle database and transactions to get a good snapshot of your database. Then (because it's an image-based solution) you can recover the Oracle DB, OS, installed applications, running services, data, and etc to that specific recovery point. Another nice thing is that ShadowProtect can quickly virtualize a backup image as a VM using Oracle's VirtualBox, MS Hyper-V, VMware, Citrix ZenServer and/or RedHat's KVM. Over all ShadowProtect's a pretty powerful and easy to use Windows backup tool.
Oh, and ShadowProtect's integrated with Oracle's VirtualBox technology (it's called ShadowProtect VirtualBoot) which makes it SUPER easy to spin up a backup image as a VM and verify (read "TEST" in capital letters) whether you've got a solid backup of your Oracle DB. I'd hate to find out the day after the excrement/fan fiasco that my backups were unusable. Please test! (I'm cringing in my chair here.) Then let us know whether you agree with your boss.
Cheers!

Find out all oracle databases on the system

hi
i want to list all the oracle databases existing on the system.Not all the table list but the database list for Oracle.
Can anyone help in this matter. I would be thankful.
trushant

Assuming you really mean databases (as distinguished by different SIDs or service names), I don't think there's any way to that with JDBC; you have to know the name of the database before you can connect to it.
If you mean the list of all schemas (which are called databases in other database products) then you can inspect the ALL_TABLES table:
SELECT DISTINCT OWNER
FROM ALL_TABLES;This won't list all schemas, but it will list all schemas that the connecting user has access to (if there's a table in the schema); users with DBA privileges see everything, of course. You could also look at the ALL_USERS table.
If neither of those answer the question you're asking, please clarify what you mean.

Just started supporting Oracle Databases for SAP Systems

Hello Guys/Girls,
I am working as oracle dba for the past 7 years, but this is the first time, I got an opportunity to adminster databases supporting SAP systems. I am doing search on SAP Network, and gathered information on BRTOOLS, SAPGUI etc., but could not find the details what I am looking for like, database objects growth rate, sap-oracle database performance specific details, as a oracle dba what are the DOs&DONTs etc., After made a lot of search on google, I found a book from O'Reilly, but that book covers older SAP, and Oracle versions. Our Client uses oracle 9i, and 10g primarily.
I am confident as a Oracle DBA supporting non-sap systems, but not SAPsystems. Is any one of you pls., suggest me or provide me some guide lines in terms of Database Management.
Appreciate your time!

Alert mail configuration for backup / Oracle database

Hello All,
I am trying to configure alert mail for successful backup in the system and i have did with most of the configurations. The steps are as follows:
Configured mail in 000 client and also assigned mail id for a user
Configured the method CCMS_OnAlert_Email_V2 (set the parameters and its auto reaction method)
Configured the nodes CCMS Monitor templates -> Database -> Oracle -> Backup / restore -> backup status -> last brbackup run and last successful complete backup with the method CCMS_OnAlert_Email_V2 as mentioned in the SAP note 176492
And after these configurations we receive the mail successfuly. However there are few issues which i would like to get corrected / clarified. Whenever a backup is started i am receiving a mail stating that brbackup has been started and whenever a backup fails i am receving mail stating brbackup is failed with some return code. But i am not receiving any mail after successful completion of backup. Am i missing any configuraions here? Is this the standard one and other configurations required for mail on successful backup? Please suggest
Regards,
Anandh

When should a message trigger an alert?
1.Always (at every message): The Alert Monitor triggers a alert with the corresponding message value for every message.
2.Message value (color) has changed: The Alert Monitor only triggers an alert if the alert color of a reported message changes. For example, an alert is triggered if a red message follows a yellow message.
3.The message sent has changed: The Alert Monitor only triggers an alert if the color or severity of a message changes or if a new message is sent.
4.Never: The Alert Monitor does not trigger any alerts.
As your requirement, I would suggest it to be set to "Always"
Please let us know how it works.

I want to do cold backup of 10g database. Do I need to shutdown Oracle Application server and listeners before doing cold backup and start them again after backup done.

for taking cold backup then its better to shutdown the apps server as well
database.I would recommend to you whenver you are going to take cold
backup for db then its better for you to take apps cold backup too if
the cold backup goes after you applied any patch ,within E-Biz tech the
patch activity affect apps files too.

How to backup oracle database in C# application

Hi,
Could anyone please tell me about a full script that will backup my Oracle XE "Express" database. I have user schema and it has tables with data and I want to backup them. I hope someone tell me how. I want to do it inside a button so it can be easy for me to just press on button and it will continue its job. Thank you very much for your help.
Any method is appreciated from you. So I just need the way that I can do it. In Oracle forms I used to use exp but in C# I don't how.

ok
Even this is ODBC forum, you could check for $ORACLE_HOME/bin/Backup.bat ... analize that script. You could call it from c# with Process Class, and process.startinfo.

OS crush without backup Oracle Database (DB 9i)

Dear All Experts,
My Oracle DB is installed on Window Enterprise 2003R2, all installation files of DB keep in another partition (driver D:) beside OS partition (C:).
Now, My OS crushes, I want to reinstall a new OS and recover all DB files back. is it possible?
Please kindly give advice for this.
Thanks and regards,
Heng

Yes, you should be able to recover your database.
You need to reinstall the Oracle 9i software to the same patch level as it was earlier. When doing the install, choose to not create the database -- because you already have one. After the installation (and applying patches), use ORADIM to create the OracleService.
You need to restore the database parameter file (initSID.ora or spfileSID.ora) from a backup. The entry for control_files would reference the existing control files. Thereafter, Oracle would read the list of datafiles from the controlfiles.

Can I use DB13C for central backup scheduling of MaxDB and Oracle databases

Hello,
we have installed Solution Manager 7.0 on Windows with MaxDB. We want to use DB13C to schedule and Monitor our database backups. We have 8 systems with Oracle Database and 7 systems with MaxDB database, 1 DB2 and 1 MS-SQL Server . Due to QAS issues we can´t migrate to one database system. Is there a possibility to handle all database systems from our Solution Manager ?
Thank you
Heiko

You can use DBACOCKPIT for that purpose. Import the systems from the SLD.
