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.

Best Practices for deployment of Oracle 10g database.

Hello ,
Is anyone aware of a whitepaper/ document that talks about best pratices in deploying a database on Oracle 10g and configuration of the database to utilize all the features available in 10g ( eg. ADDM , reports setup etc )
Thanking you in Advance.
Cheers..rCube

Appreciate the input Jaffer. Thanks.
However I was referring to a Best Practices whitepaper like the one existing for Data Guard & MAA available at the follwogng url : - http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm
Is there something available along the same lines ?

Oracle 10g database as Resource manager and heuristic transaction decision

Hi,
I have read in documents about distributed tarnsaction that resource manager like oracle databasecthat are involved in distributed transaction can take heuristic decision(unilateral decision) and can either rollback or commit the transaction associated with itself without having confirmation from the transaction manager.
I want to know how a resource manager take this unilateral decision and can we set this as parameter either in resource manager or in application server.
Thanks in advance

Hi,
Following are some links to documents.
Handling Heuristic Completions
http://edocs.bea.com/wls/docs81/ConsoleHelp/jta.html
A heuristic completion (or heuristic decision) occurs when a resource makes a unilateral decision during the completion stage of a distributed transaction to commit or rollback updates. This can leave distributed data in an indeterminate state. Network failures or resource timeouts are possible causes for heuristic completion. In the event of an heuristic completion, one of the following heuristic outcome exceptions may be thrown:
HeuristicRollback—one resource participating in a transaction decided to autonomously rollback its work, even though it agreed to prepare itself and wait for a commit decision. If the Transaction Manager decided to commit the transaction, the resource's heuristic rollback decision was incorrect, and might lead to an inconsistent outcome since other branches of the transaction were committed.
HeuristicCommit—one resource participating in a transaction decided to autonomously commit its work, even though it agreed to prepare itself and wait for a commit decision. If the Transaction Manager decided to rollback the transaction, the resource's heuristic commit decision was incorrect, and might lead to an inconsistent outcome since other branches of the transaction were rolled back.
HeuristicMixed—the Transaction Manager is aware that a transaction resulted in a mixed outcome, where some participating resources committed and some rolled back. The underlying cause was most likely heuristic rollback or heuristic commit decisions made by one or more of the participating resources.
2. Understanding EJB Transaction
http://www2.sys-con.com/itsg/virtualcd/Java/archives/0504/tyagi/index.html
Unilateral Decisions
The transaction manager allows certain heuristic or speculative decisions to be made based on the state of all participating resources in a transaction and the underlying two-phase commit protocol. A heuristic decision occurs when one of the resources in the transaction unilaterally decides to commit or roll back the transaction without permission from the transaction manager
3. Oracle® Containers for J2EE
http://download.oracle.com/docs/cd/B31017_01/web.1013/b28958.pdf
Heuristics
To achieve consensus, two-phase commit is a blocking protocol. This means that, if a coordinator fails before delivering the final phase messages, the participants must remain blocked, holding onto resources. Modern transaction systems add heuristics to two-phase commit, which allows such participants to make unilateral decisions about whether they will commit or rollback. If a participant makes a choice that turns out to be different from the one taken by other participants, then non-atomic behavior occurs.
I got this problem while trying to do a distributed J2EE tarnsaction with two XA (one MQ and other Oracle 10g database XA) and one non-xa (oracle 10g database). According to above docs a resource manager can decide tarnsaction final state unilaterally and that can result in unatomic transaction.
Do oracle also make such decision and if yes then on what ground it takes decision? Can we change this according to our requirement either always rollback/commit anywhere as parameter setting?
Thanks

Can we install oracle 10g database on Windows Vista Home Edition?

Can we install oracle 10g database on Windows Vista Home Edition?

You didn't specify which Oracle10 Edition.
In the case of SE/SE one/EE, with a paid license Supported has a mean impact on production environments with paid licenses, since you wouldn't run on an unsupported platform facing the risk of being left without technical support from Oracle in case of an emerging issue.
For the XE Edition, this is not a certified combination, since the only certified editions are the Business, Enterprise, and the Ultimate editions, but you can try it, you don't have nothing to loose, supported, certified vs. unsupported in this case makes no difference since this XE is not supported either way (no patchsets, no bug fixes, no technical support from metalink), just an AS IS free software.
On the license agreement terms displayed when you download the XE software it states:
"No Technical Support
Our technical support organization will not provide technical support, phone support, or updates to you for the programs licensed under this agreement."
and
"THE PROGRAMS ARE PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND. WE FURTHER DISCLAIM ALL WARRANTIES, EXPRESS AND IMPLIED, INCLUDING WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE."
In case someone would be able to win a trial against oracle due to damage from the use of this software, the amount paid at maximum is 1,000.00 USD, not enough to even pay the lawyer's lunches.
For the XE users the primary source of 'kind of support' is the oracle forums, either the installation forum, the general database or the specialized XE forum.
Of course if this is for your own personal use for learning and testing and there are no third parties you could damage by doing this and if you don't have a paid license for this installation you may try it, but don't expect the Enterprise Manager to behave as defined by the manual, most of it won't work since the Home Edition doesn't have the privileges required for EM to work.
If this is your personal computer and when you bought it the computer provider installed from factory Home Edition, and if you want something to work there, you can try to install a Virtual Machine and install Oracle 10g on a supported guest OS.

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
Raj

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 setup management server in oracle 10g database

guys,
i've installed oracle 10g database into my machine. but i don know how to setup the management server (for scheduling owb10g process flows). unlike 9idb, we have an option emca to setup the management server. if anyone of u knows abt it, please help me. do i need to install the grid control just to have the scheduling mechanism? please advice.

Well, it depends heavily on what operating system you're using, what mail server you're trying to install, your network topology, etc. Realistically, this is a question that is probably better asked in a forum for whatever mail server you're trying to install...

What I can do with the free download version of Oracle 10g?

I'm new to Oracle. What can/can't do with the free download of Oracle 10g Release 2? What is the difference between Oracle 10g Release 2 and Express edition?

Express Edition has limits on the number of CPUs it'll utilize (it essentially forces itself to run single-threaded), amount of RAM it'll utilize and amount of data it will store. It is missing many of the higher level security and maintenance features you would find if you wanted to be highly available.
The downloadable version of Enterprise Edition is missing none of these, however the license states that you can only use the that version for development purposes.
I suspect you can also use the downloadable version to educate yourself on how the various features work, but it doesn't specifically say that in the license and I'm not a license expert.

Where i can fing chancges log of Oracle 10g database

Hi.
I need changes history of Oracle 10g database. Where i can find this?
Thanks.

I think you are asking "how do I set up and look at audits"
Best to ask in a Database forum. This forum is for discussing problems with Oracle Software Download (and Oracle has several hundred different software)

Can anyone suggest shud i go for Caompaq or Acer?
Which processor will best handle Oracle 10G database? Inter Core Duo or AMD Turion?
Thanks,

Hi,
I am not sure about "hosting a serveice means". i will be installing Oracle discoverer administrator and optionally pl/sql developer.
I remember that we had installed oracle10g on my friends AMD desktop....and that had killed the performance like crazy.It must have something to do with the configuration of instance. I have at least two desktops running AMD and it works perfectly fine.
>
The laptop i m buying is *250 GB HDD, 2 GB RAM and windows vista*.As Nicolas has rightly pointed out in his post, which version of Vista is this? Remember that Vista Home edition is not supported by Oracle. You might get the things to run but you cannot guarantee the stability.
The only thing i m confused bout is whther i shud go for AMD or Inter core processor.
In this case, this would be a matter of personal choice. Both processors are at par with each other (now I am not going into the details of architecture and other things).

Accessing and Managing RAC 10g database with 9i OEM

can i Access and Manage RAC 10g database with 9i OEM? If yes How?

9i EM can 'see' a 10g database and perform some basic functions (rsp. all what is known to 9i). But it cannot manage any 10g functionality , because it doesn't know it. So such a constellation doesn't make really sense. On the other hand 10g EM can manage 8i,9i and 10g databases.

Configuring Filesystem Free Disks for ASM ? Can you use free space for ASM

Is there a way to dedicate the available disk space for ASM in order to create a database under ASM?
I was hoping that I would not have to reinstall the Linux OS Enterprise 5 (Red Hat). So I de-installed my 2-node RAC environment, installed the ASM required RPMs for Red Hat linux Enterperise 5 and then proceeded to reinstall 11g Clusterware and set "Configure Automatic Storage Management (ASM)".
Did I miss something? THanks

Thank you.
I have 3 VM-Oracle guests running Oracle 11g. When I've used NFS as share that worked fine, however I was not using ASM. I know wish to get smart about ASM implementation.
Server1(rac1) Linux E5 64bit
Server2(rac2) Linux E5 64bit
Server3(asm) Linux E5 64bit (I created four partitions
./oracleasm createdisk DATDISK /dev/xvda10 OK
./oracleasm createdisk VOTDISK /dev/xvda11 OK
./oracleasm createdisk OCRDISK /dev/xvda12 OK
./oracleasm createdisk OFRDISK /dev/xvda13 OK
On Node1 and Node 2
./oracleasm scandisk
Scanning the system for Oracle ASMLib disks: OK
After this should I or how do you make a partition shared? Could I used NFS? so that I can proceed with the RAC install and then create database .

How to remove archive log files from ASM managed 11g R2 database?

Greetings
Did you check RMAN,
RMAN>show all;
CONFIGURE RETENTION POLICY . . . .
CONFIGURE ARCHIVELOG DELETION POLICY TO [CLEAR | NONE | APPLIED ON STANDBY];
DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;
DELETE NOPROMPT ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-10';
This will be part of your RMAN Backup scripts/process
