What commands used for taking backup of oracle database using BR*Tools

Can somebody please help me urgently to know what are the commands used for taking backup of oracle database using BR TOOLS.Also specifythe commands in detail which can be used for taking backups of oracle database ,Online Redo log files in databse using BRBACK tool,Archiving of offline, redo log files using BRARCHIVE, and Restoring a Database using BRRESTORE tool Commands(Plese specify the commands with their Syntax used).Also specify the commands with their Syntax which are used for taking backup of oracle database(online,Offline redo log files) into Tapedrives using BRTOOLS commands.
Thanking You for helping (in advance).

Dear Ashish,
BRBACKUP / BRARCHIVE calls the operating system command to copy the files.
Simple approach to get the commands is as follows.
1. Set the BR_TRACE (as given in the SAP note 29321) and run the command for which you need to know the OS / SQL commands.
2. This will generate the log file with the trace information. This trace has the information of the commands used by the job you have run.
Hope this helps.

Madhukar

Difference in select for update of - in Oracle Database 10g and 11g

Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience):
DECLARE
  v_ename bonus.ename%TYPE;
BEGIN
  SELECT b.ename
    INTO v_ename
    FROM bonus b
    JOIN emp e ON b.ename = e.ename
    JOIN dept d ON d.deptno = e.deptno
   WHERE b.ename = 'Scott'
     FOR UPDATE OF b.ename;
END;
/While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

It seems that my question was answered here - http://stackoverflow.com/questions/2736426/difference-in-select-for-update-of-in-oracle-database-10g-and-11g

The behaviour seems like it really is a bug and can be avoided using non-ANSI syntax. (It makes me wonder why Oracle maintains two query languages while dumb me thinks that this is just a preprocessor matter and query engine could be the same).

Can i use "Oracle Database 12c: Performance Management and Tuning " training for getting certification on "Oracle Database 11g: Performance Tuning 1Z0-054"

i have taken "Oracle Database 12c: Performance Management and Tuning new" training from oracle university. Now i would like to get certified on "Oracle Database 11g: Performance Tuning 1Z0-054" exam. Is it possible ?

I essentially endorse and refer you to Matthews' and John's post above.
I would differ with slightly with Matthew because my guess is you would often be able to use like for like 12c training for an 11g certification ( I believe there are precedents). BEFORE ANYONE ASKS THE OTHER WAY DOESN'T HAPPEN.
.... but totally concur with Matthew you would ill advised to procede on that basis without one of:
- This being advertised as possible on the website : e.g. https://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=654&get_params=p_id:169 ... option 2 show courses.
- Confirmation from Brandye
- Confirmation from an Oracle Certification Support Web Ticket ( http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP )
... The more common (and in my opinion usually better) way would be get your 11g DBA OCP ( or higher first) and then take the 1z0-054. I am almost certain they will accept your 12c course for the 11g DBA OCP.
If you are choosing the route of not being a 11g (or 12c ) DBA OCP first but are on option 2 and relying on the course for certification then the issue is more in the balance and you are even more strongly advised to get confirmation before proceding (remember if the rules need to be changed for you only then any profit out of the exam is lost).
In general my understanding is Oracle would prefer to encourage people to train on the latest version of product that is available for training and will prefer to avoid restrictions which would cause you to train at a lower version. ( This is simply my guess at Oracle University Policy ... personal opinion only).
Having said all I have said I'd encourage you to go with the advice of the earlier two posts.

Step for performance tuning in oracle 10g

Reserving the sessions for a user in Oracle database

Hi,
Suppose the Oracle database is running in dedicated mode.
I want sys or abc user to have some sessions reserved for them.
This is because if there is heavy load on the system and all the sessions are used up then we can not connect to database to see what is happening inside.
However, if we have got some policy on the number of reserved sessions for a user then we can always log in as that user and see what is happening inside the database.
Consider any version of database, if you can get what I am asking then try answering it, else I can elaborate it further.
Please note that I do not want to change the server mode from Dedicated to Shared.
Any help will be appreciated.
Thank you.
--Harvey.

Hi Guys,
There has to be some way to achieve this. But your sugestions are correct to have a user connected always if we are going to face an issue.
Any ways if there is no other way to achive this then we can not do any thing, else Oracle come up with something.

Web Server Options for APEX Installation on Oracle Database 10g

Hi. We are installation a APEX on a test server that is running Oracle Database 10g 10.2.0.4.0. As I understand it there are two Web Server Options:
1) Oracle HTTP Server (Apache)
2) Oracle Application Express Listener
Do both of these work for Oracle Database 10g 10.2.0.4.0? I thought I remember reading somewhere that only the Oracle Application Express Listener would only work with database version 11 or higher.

Do both of these work for Oracle Database 10g 10.2.0.4.0?Yes.
I thought I remember reading somewhere that only the Oracle Application Express Listener would only work with database version 11 or higher. No, that restriction (with the exception of 10g XE) applies to the third web server option which you haven't mentioned: Embedded PL/SQL Gateway (EPG), as discussed in your previous thread: +{thread:id=2201975}+

Steps for cloning a RAC 10g database

I would like to clone our production RAC database into my development environment. Can anyone help me by providing the steps to follow? I could not find anything on Metalink. Thanks in advance for your help.

I did the same few days back you can get a lot of help from http://idevelopment.info/ go to RMAN 10g and then Duplicating a Database using RMAN - (UNIX / Linux)
however I would give some of the steps
1. Take a full database backup of your Database using RMAN and catalog database, make sure you include current controlfile.
2. Create a new pfile from the original database pfile or spfile as the case may be.
3. comment out all RAC specific parameters such taht you can use the new pfile to start the database in single instance mode.
4. create a new sid for the new database and start the database in nomount mode using the edited pfile.
5. now connect to RMAN using your present database as target the new database as auxiliary and catalog database.
6. execute the duplicate database command.
7. You may need to do dbfilename convert if your directory structure is not same as of the original database, this is true for ASM too.
8. After the RMAN session ends control file should have been restored at the specified location in the edited pfile.
===
in case OMF is being used
9. shutdown the database (it can be in shutdown mode already).
10. Check the name of the controlfile and provide the name in the pfile.
====
11. start the database in single instance mode it should start.
12. now shutdown the database and uncomment the RAC specifiv parametors, please chek entries of REMOTE LISTENER etc.
13. register the database and instances with the CRS using srvctl
14. start the database with srvctl

Long Term Storage ideas for Data in an Oracle Database

We have data that we no longer need access to and want to archive it on tapes for long term storage.
We want to save the data using datapump or rman from time to time and and store the exports/backups on tapes. The issue we don't want to face in the future is , if Oracle deprecates the methodology we used to save the data in 2012, we no longer have a way to retrieve the data into a database 10 years from now.
This may sound crazy, but hear me out. Before datapump existed everyone was using vanilla exp to export the data. Now we have datapump as exp's upgrade and we have rman too. What if in 2012 we took an export using datapump or a backup using rman and save it off on a tape. 10 years go by and in 2022 management wants to look at the 2012 data. Lets say by this time Oracle's mothodology changes and they have a much more efficient/robust export/backup method. One way for us to keep the old backups up to date is to import the data back before the method we used in 2012 is deprecated and then export/backup the data using the new method to keep the exports/tapes in sync with then current technology.
My question is, what methods of saving large amounts of data do you recommend/use to save data to a tape so that you don't have to worry about changing times.
An idea I heard is to save the data as insert statements. This would work for most of the data except for blobs.
Any help would be appreciated.
Thanks in advance.

Won't an intelligent compression algorithm take care of a lot of the overhead for that?
>
That's certainly a valid point to make and one that the OP can test. And because the duplicated metadata is identical and in the same physical row location there may be compression algorithms that can reduce it to just one set.
There were two points I was trying to make.
1. Don't just save the data - save the metadata also.
2. The metadata for each row will be the same so if you use an INSERT format that duplicates it for every row you are potentially wasting a lot of space.
Your other point was probably more important than these or anything previously mentioned.
>
perform restores of the entire database every couple of years or so to make sure that your
database isn't degrading
>
Regardless of the format and media used to backup the data it is important to verify the integrity of the backup periodically.
There are a lot of ways to do this. One way is a simple MD5 (or other) checksum of data at some level of granularity and then periodically read the data and confirm you still get the same checksum.
In my opinion the more generic the format that the data is saved in the better the odds that you can recover the data later no matter how technology may have changed.

Typical resolution logic for client connection request (Oracle Database 11g)

Salam, hello everyone, I would know the process that oracle follows to connect a client to a database (local or remote connection) via this command : connect username/password[@connect_identifier].
Can someone help me with that?

The first decision is whether the connect request includes a connection string or not. Examples:
This does,
connect [email protected]
An this doesn't,
connect /
Your question regarding "LOCAL env var" I think is referring to client environment variables? They are tested with decisions for TNS_ADMIN,ORACLE_SID, and ORACLE_HOME at several points. Remember that the client process may be running on a remote machine, or on the server machine from the same Oracle Home as the instance or different.
That should give you a good start. If it doesn't, post your email and I'll send you a full description. The usual route for contacting authors is through the publisher, but we can short-circuit the process here.
Don't worry about Mr Bakker thinking that we do not understand SQL*Net. He has not seen any context, and his constructive criticism is based in incomplete data. You will soon understand SQL*Net better than most.
Please remove the diagram.

path d:\jdk\lib;d:\jdk\bin;c:\windows\command;C:\temp\BIN;c:\temp\jdbc\lib\classes111.zipYou've added classes111.zip to your PATH, not your CLASSPATH.
Add it to your CLASSPATH using:

What are the space requirements for creation of a Oracle database.

Hi,
How much space do we require to create a database, say the data
size is 2GB.., is there any estimate like the space should be 3
times or 4 times of the data size..?
Regards,
G. Rajakumar.

It really depends on how you set up your tables. Storage
parameters, block size, etc etc.

Needed steps for installing oracle 10R2 on windows server 2003

Hi to All,
Can anybody give me steps for how to install oracle 10R2 on windows 2003 server in production environment and what is the preinstallation task and postinstallation task.
Thanks and Regards
Mohd Khaja

There is one pre-requisite that is missing from the documentation - ensuring that the administration team is adequately trained.
Since you are asking this question, I wonder whether your team is properly prepared for, and aware of, the possible nuances or changes from default that might be relevant to your environment.
For example, is your team familiar with the concept of Flashback Recovery Area and how it may fit, or conflict with, your production needs? Use of RMAN? Location of Oracle software Inventory and implications in your OS-level backup? How to configure both the software and the database to meet your Service Level Agreement requirements.
The referenced document is an excellent first step, as it asks some of the questions. If you are serious about production stability, you want to go through that as well as get appropriate level of expertise in your shop.
