Oracle backup of more then 1-2 TB database

Hi all,
Can anybody suggest me how to take a backup of more than 1-2 tb of database.I know many people will recommend to use Rman, bit is slows down I/O and the rman takes aroung more than 30-40 hours to complete.So is there any solution, if yes, then how to take the backup and recover the same.Like anybody have any idea about SAN mirroring.

You can use RMAN options >
- Compression
- Parallel option < Channel configuration
- Rate option
- Duration option
- Block change tracking
- Incremental backups
So you save time, spaces and load of your system
Hope it helps!

Oracle RAC with more then two nodes?

Hello,
knows anybody a reference client project that use Oracle RAC with more then two nodes on a Linux environment?
Many thnaks!
Norman Bock

Hello Norman,
XioTech is a SAN company that has a project called "THE TENS". They configured and ran a 10 node RH Linux Oralce 9i RAC. I understand they want to see if 32 are possible. I am sure if you ask them, they would be happy to give you the details.

How to retrieve more then one record from database

I am doing a SELECT FROM WHERE SQL statement on a database which returns more then one record. I want to retrieve certain column values from the selected records. How do I do that? If only one record is returned, I know I can do a data operation with operation set to 'Get-Retrieve Values from Record' and Record to operate on set to 'Current-Use current record'. I need to find out how to configure to data operation window in the case more then one record is returned by the preceding SQL statement. Depending on the number of records returned, I can dynamically create array variables to store the 'to be retrieved' column values, just dont know how to retrieve them.
Any help will be greatly appreciated.
Thanks

I apologize for not being clear in explaining my problem, perhaps I should have posted an example. Anyways, I was able to figure out the solution. I was doing an 'Open SQL' statement which was selecting multiple records (rows) from a table in the dB. I was storing the number of records returned in a local variable. Then, I wanted to retrieve certain columns of all the selected rows (records). In the "Data operation", I was choosing the 'Record to operate on' as 'Current-Use Current Record'. Changing this field to 'Next-Fetch next record' fixed the problem. I then retrieved the values of those columns into a dynamically created array variable whose dimensions came from the local variable which stored the number of records returned in the SELECT SQL statement.
Thanks

Oracle RAC support more then one database

My company's requirement is to have multiple database, instead of multiple schemas in the same databsae. The only reason to have multiple database is to support different applications with different database versions. for eg. One application sitting in Oracle RAC with have version 10.02.0.0. and other applications will have 10.02.0.2.

You can have multiple instances on a node or multiple databases on one RAC cluster. However a more important factor that should be considered is to ensure that the servers are capable of handling the additional workload.
Also to consider is the software compatibilities between various versions of Oracle RDBMS, ASM and the Oracle Clusterware.

Taking more time(more then 12 hours) while syncing

I sync some music(about 340 MB) and pics (about 200 MB) to my new Ipad for the first time, and it was ok.
But when i connect my Ipad Second time to my laptop(running on Windows 8) it was syncing & taking backup for more then 12 hours but still it was not completed. Is there ny problem in My Ipad or in my Laptop or in Itunes.
Kindly help me,i bought my Ipad just 5 days before.

Hello,
Looks like you have a 1:M relationship from TableA to TableB, with a 1:1 back pointer from TableB to TableA. If triggering the 1:M relationship is causing you delays that you want to avoid there might be two quick ways I can see:
1) Don't map it. Leave the TableA->TableB 1:M unmapped, and instead just query for relationship when you do need it. This means you do not need to call tableA.addTableB(tableB), and instead only need to call tableB.setTableA(tableA), so that the TableB->TableA relation gets set. Might not be the best option, but it depends on your application's usage. It does allow you to potentially page the TableB results or add other query query performance options when you do need the data though.
2) You are currently using Lazy loading for the TableA->TableB relationship - if it is untriggered, don't bother calling tableA.addTableB(tableB), and instead only need to call tableB.setTableA(tableA). This of course requires using TopLink api to a) verify the collection is an IndirectCollection type, and b) that it is hasn't been triggered. If it has been triggered, you will still need to call tableA.addTableB(tableB), but it won't result in a query. Check out the oracle.toplink.indirection.IndirectContainer class and it's isInstantiated() method. This can cause problems though in highly concurrent environments, as other threads may have triggered the indirection before you commit your transaction, so that the A->B collection is not up to date - this might require refreshing the TableA if so.
Change tracking would probably be the best option to use here, and is described in the EclipseLink wiki:

Iphone backup (more then one)

ok i think my backup is corrupt,now i can delete it and make a new one then itunes will add to that one right? well thats what i think is corrupting my backup (when new info is added to current backup.. how do i tell itunes to make a new backup without me deleting the other one? thnx ....

That's crappy, but your right it verywell could be my phone. setting up as new is kinda what I'm trying to avoid. That's what I had to do last time when all my Info was wrong after the first restore, that was a restore from backup and it was corrupt so I restored as new. I got lots of data, logins, and app creds.it'll take forever to put all that back in the phone. My phone is fine now but that don't last forever, if I remember correctly in previous Versions of iTunes, u could have more then one backup.
Seeing how I already restored as new and not from backup I don't even kno if the current backup is corrupt but I would like choice of two backups.
Thnx for your input wjosten

Oracle Data Miner - one project (workflow) more then one user ?

Hi,
Is it possible to have more then one DM user working on one DM project / workflow?
Example I have DMUSER1 and DMUSER2
DMUSER1 created project and some workflow. I need DMUSER2 to be able to modify that same workflow if possible simultaneously.
Something like in OWB where we can use more than one user on creating mappings.
How is that possible?.
Regards
Kreso

Hi Attila,
You can find the transform package at the following link:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e16760/d_dmtran.htm#i1013223
The ODM mining algorithms use techniques that are not exposed.
However, there are a lot of features in the db that are available to you to build your own.
As for an optimization package, I know there are some internal implementations but I am not aware of one in the db that is exposed.
Thanks, Mark

HOW DO I USE MORE THEN ONE ITUNES WITH MY IPHONE WITHOUT ERASING MY MUSIC?

I have two different laptops with iTunes on it. I use both of them but my iPhone only works with one iTunes. I plug it into the computer and it says that my iPhone cannot use more then one iTunes. Is there a way I can use both or no?
YES I AM CLICKING MANUELLY ADD SONGS TO MY iPhone.
I just bought my iPhone about a week or so ago.
Please help ASAP.

I clone my library to a portable drive using SyncToy 2.1, a free tool from MS. I run this both at home & work so that I essentially have three identical copies of my library for backup redundacy, any of which I can use to update my iPods and my iPhone. I use iTunes Folder Watch occasionaly in case I've managed to download, for example, a podcast at one location but overwrite the library with a newer copy updated at the other. It can be done but you need to take considerable care...

Time machine is trying to back up more then the drive has on it

I'm doing an intial backup on a fresh Time Machine drive ... my computer has 1.66TB of files there are no external drives etc selected. Time Machine wants to back up 1.98TB !!!! It wants MORE then the drive has on it !!!!!
How is this possible ... Crazy stuff !

Time Machine will require about 200 TB of free space.
Unfortunately, a new 2 TB drive will not have exactly 2 TB of free space. so that is where the problem is arising.
Wow.. that is a lot of space.. LOL!!
It is confusing now with the change from v5 utility which recorded capacity in binary bytes to the v6 utility which records digital bytes.
So the same drive looks different on both. But the computer is going to always use binary bytes.
Older v5 utility.. shows capacity. 2.7TB. That is standard binary value for a 3TB drive. Always sold with numbers as inflated as possible.. ie digital bytes..
c
So the available is shown under the partition correctly.
In v6 utility.
We discover the disk has more free space than the v5 utility says when it is formatted... and empty.
The confusion caused by using digital bytes.

Set more then 3 values in link

Hello,
i am using oracle 10g apex 3.2.
I created a interactive report,with shows 5 columns in page 1.
Now 2nd column i made it as link.
On clicking that link it goes to page 3.
When i click the link i want to set few items of page 3 with page 1 values.
But in the column link(report attributes) of the interactive report i could see only 3 items can be set.
What to do if i need to set more then 3 values?
For More info on what i am doing---------
Page 3 is having a form whose values i need to fill from page 1.A user need to click the link i.e. col2 on page 1 and then it goes to page 3 and could be able to see some values in the form of page 3 already filled.I want to send total 6 values.
Thanks
Swapna

Hi,
Option 1>>>
When you click link on interactive report , send the primary key to page 3 which contains the form.
In page 3 add a on load , before header process which will populate the other items based on the primary key value..
Option 2>>>
You can enter comma separated item names / values in the link tab of interactive report..
eg. Name Field you can P1_ITEM1 , P1_ITEM2 , P1_ITEM3 and in value field you can enter the corresponding values eg.. #field1# , #field2# , #field3#

Shijesh

Hello why cant we store more then 25,000 songs that have been uploaded in the Icloud from my cd's

Hello why cant we store more then 25,000 songs that have been uploaded in the Icloud from my cd's, I'm a DJ and the purpose of getting the Icloud was not only for backup but to have access to all my music and this 25,000 song limit is not acceptable for me. I also upgraded my icloud drive to 200gb in hope that this would help, did it? I dont know as of yet, I just did it any thoughts out there??

Is ORACLE slower on Windows then on Linux ?

Hi,
I'm suppose to choose the platform for Oracle .... Linux or Windows 2008 Server ...
Ones we've installed Oracle on Windows 2003 Server and it was really slower like 200-300% ..... we did simple default install
Does anyone know if this is a fact that Oracle will run slower on Windows platform then on any other ? Any experiance with that ? If we are talking about 5-10% then this is ok and I'll stick with windows ...
Cause I know how to deal with windows much more then how to deal with Linux admin, install and other stuff ...
Thank you...

Hi Charles,
Installing a virus scanner on the server, especially if it is permitted to scan program and data files used by Oracle.Ha, that a good one! That the FIRST thing I check!
Also, I've seen high demand screensavers (fractals) clobber Oracle performance . . .
Oracle on Windows uses a thread modelThat's actually one of the few "positives" about running Oracle on Windows . . .
rather than providing a performance comparison between Linux and Windows.Fine, try here:
www.dba-oracle.com/oracle_tips_linux_oracle.htm
"Roby Sherman performed an exhaustive study of the speed of Oracle on Linux and Microsoft Windows using identical hardware. Sherman currently works for Qwest Communications in the data technologies group of IT architecture and transversal services. He is a recognized expert in designing, delivering, tuning, and troubleshooting n-tier systems and technology architecture components of various size and complexity based on Oracle RDBMS technology.
Sherman concludes that Linux was over 30% faster:
"From perspective of performance, RedHat Linux 7.2 demonstrated an average performance advantage of 38.4 percent higher RDBMS throughput than a similarly configured Windows 2000 Server in a variety of operational scenarios." Sherman also notes: "Another point of contention was Window's lack of consistency between many database administrative functions (e.g., automated startup, shutdown, service creation, scripting) compared to what DBAs are already used to in many mainstream UNIX environments (e.g., Solaris and HP-UX)."
Mr. Burleson's comments seem to be out of line. No, I'm right on the money.
*I've seen enough companies get burned by Windows (unplanned outages, data corruption) to speak with confidence.*
Bottom line, it's malfeasence to recommend any OS platform for a production database application that has an unsavory history.
It does not take a genius to figure out that an OS with this kind of history should not be used with any data that you care about:
- "blue screen of death"
- legandary security vulnerabilities
- memory leaks you could drive a truck through
- Patching weekly
- The world's most incompetant tech support
I'm not alone in this opinion:
thetendjee.wordpress.com/2007/01/22/oracle-10202-sucks-on-windows/
www.google.com/search?&q=%22windows+sucksMr. Burleson,
Good point on the screen saver.
Comparing Windows 2000, released in March 2000, with Red Hat 7.2 which was released in ... sorry, forgot the date, but I put in a couple servers running that release of Linux into service in 2001. I was kind of hoping that you would have an article which pits Windows 3.1 against the original Linux release. :-)
You might be happy to know that things have changed significantly since Windows 3.1, and also significantly since Windows 2000. There were many improvements in Windows 2003 over Windows 2000 (I happened to read a couple large books on the subject of Windows 2003 Server a couple years ago). This page contains a couple links that you may want to browse:

Windows sucks... I have heard that the Microsoft Windows operating system is on barcode scanners, phones, and even car navigation systems. I had no idea that vacuums also utilized Windows, thanks for the heads-up:

Regarding blue screen of death, those are rather rare with versions of Windows since the release of Windows 2000. The last blue screen that I saw on a server happened when an ECC memory module started experiencing multiple hardware bit errors which could not be corrected by the ECC memory logic. The server hardware forced the blue screen to prevent data corruption. The previous blue screen? A Windows NT 4.0 Server (circa 1996) when a new RAID controller was added to the server.
Regarding legandary security vulnerabilities, well I don't think that it quite qualifies as legendary. However, given the wide usage of Windows (particularly by people just starting to learn to use computers), there will very definitely be more security issues to contend with - Windows often offers a larger attack surface than other operating systems. Yes, there have been many security problems over the years.
Regarding memory leaks you could drive a truck through, I have to say that in a server environment I have not experienced that problem. On a desktop environment, I would say that it is typically the fault of poorly written applications which cause the memory leaks. Windows will often clean up after the poorly written applications when they are closed.
Regarding patching weekly, yes there are typically frequent security and bug fixes released for the Windows platform, but I suggest that if someone is patching weekly on a server, there is probably a larger problem to be addressed.
Regarding the world's most incompetant tech support, I am not sure that I follow your logic:

No definitions were found for incompetant.
Suggestions:
- Make sure all words are spelled correctly.
- Search the Web for documents that contain 'incompetant'"
As previously stated, consideration should be given to the operating system which is most familiar to the OP.

SAP & Oracle Backup Integration

Hi,
Have Oracle 10g as backend for database & Legato Backup Software has been installed on the server. Could anyone please let me know that if i use DB13 for taking online & offline backups how would it integrate with the Legato Backup Software & is there any special licences required for integration with SAP. Hoping to get a reply soon...

Hi
For Oracle Backups the preferred backup method is RMAN. I suggest you read docs for more information. Try focusing on incremental backups as you suggested space constraints.
