Which is the best Method for Restoring a Backup in a Secured manner?

Dear Legends,
I got a requirement/scenario to restore a backup of Oracle 11gR2 database. Imagine that I'm not aware of the database files and how the backup was taken by someone else. Now I would like to restore it, let me know how and securely the backup can be restored without disturbing the existing environment.
So for I have crossed the doc
1. "Introduction to Backup and Recovery"
2. Oracle Distilled
3. "www.myoracleworld.net - Installing 11GR2 on redhat 5U5 64-Bit"
Is there a valid restore document covering only RESTORE a Database using RMAN with oracle Docs?
My Understanding:
1. Using RMAN RESTORE command we can restore the database.
2. A Valid/Consistent backup should be available to restore database in any format which RMAN Understands.
3. Needed Backup files - SPFile, Control File and Data File
Please correct me if my understanding is wrong.
Questions:
1. What are the things I need to consider before restoring?
2. What are the Questions/Info that I need to gather ?
3. Need to Collect ASM Details if any?
Thanks,
Karthik

Hi,frank
thank you.I create my page as follows:
1.drag a view "roleInfo" as "search form" from datacontrol,iteartor is "roleinfoiterator",
2.drag the same view "roleinfo" as the result table and select "enable selection";in page definition add an iterator "roleinforesultiterator" and edit table to bind to "roleinforesultiterator"
3.drag opertion "delete" below "roleinfo" as a commandbutton "delete",edit the "delete" button to bind to "roleinforesultiterator"
4.add a command button "create" to create new record
The problem is :after I create a new record by press "create" and create new within another form,then commit and return to my search form,if I select a record in result table by tableselectone radio button and press "delete" button,sometimes it works fine,but sometimes,the wrong record was deleted.
thank you

What is the best method for backing up photos in IPhoto?

I have over 10,000 photos in IPhoto and am looking for the best method for doing a backup (or an archive?). I'm now using ICloud and it appears it's just photo streaming and does not have storage capability. External hard drive, copying to a DVD, other suggestions?

Most Simple Back Up
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex:
Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically. Examples of such apps: Chronosync or DejaVu . But are many others. Search on MacUpdate
My Routine
My Library lives on my iMac. It’s Backed up to two external hard disks every day. These disks are permanently attached to the iMac. These back ups run automatically. One is done by Time Machine, one is a bootable back up done by SuperDuper
It’s also backed up to a portable hard disk when ever new photos are added. This hard disk lives in my car. For security, this disk is password protected.
I have a second off-site back up at a relative’s house across town. That’s updated every 3 or 4 months.
My Photos are backed up online. There are many options: Flickr, Picasa, SmugMug etc. However, check the terms of your account carefully. While most sites have free uploading, you will often find that these uploads are limited in terms of the file size or the bandwidth you can use per month. For access that allows you to upload full size pics with no restrictions you may need to pay.
Every couple of months I test the back ups to make sure they are working correctly. It’s very easy to mis-configure a back up application, and the only way to protect against that is to do a trial restore.

Which are the best settings for exporting comps before edditing in Premiere Pro

Hello everyone!
As the title says, which are the best settings for exporting comps from AE to Pr.Pro and then edit them?
Let me explain: I have two comps in AE (intro and outro) and want to export them in Pr.Pro for edditing along with a fottage i shot.
When i render them the size of the files are huge (30 sec= 7GB).
Which is the best method (and settings) i can export the intro and outro to a 'normal' file size and then put them in Pr.Pro without loosing any quality??
[Comp settings: HDTV 1080 29.97 (1920x1080)]
AE and Premiere Pro both CS4

If you're rendering and exporting an intermediate video file to go from After Effects to any other piece of post-production software (such as Premiere Pro), you want to make sure that you're not losing any quality.
Most compression methods, which make movies smaller, also lose some of the image data---i.e., quality. There are a few compression methods that don't lose any image data; these are "lossless" codecs. These lossless codecs do decrease the size of a video file, but they're nowhere near as effective at decreasing size as the lossy codecs are. But file size isn't important when you're doing post-production work. Big files are a fact of life in post-production.
Examples of lossless codecs include the PNG codec and the Animation codec at the highest quality settings, both of which can be used in a QuickTime (.mov) container. I prefer the PNG codec; it's more efficient for photorealistic images, whereas Animation is more efficient for things like cartoons. There are lots of other lossless and nearly lossless codecs. A lot of people that do video editing like the Lagarith codec, but that is something that you'd have to go and get; it's not part of a standard CS5 or QuickTime installation.
See these FAQ entries for information about compression and why file sizes are big for losslessly encoded files:
"FAQ: Why is my output file huge...?"
"FAQ: What is the best format for rendering and exporting from After Effects?"
By the way, keep in mind that you don't always need to render and export an intermediate movie to go from After Effects to Premiere Pro. There are other ways to move data back and forth between these applications, including Dynamic Link. Which is best depends on the specific circumstance. See "Working with Premiere Pro and After Effects".

Which is the best iOS for iPhone 3G? I am currently on 3.1.3 !

Which is the best iOS for iPhone 3G?
Should i update it to the latest 4.2.1 or let it be on my current firmware 3.1.3?
I have heard that 3G is best on 3.1.3?
Comment?

If I may, I agree that version 3.1.3 is the best for the iPhone 3G, however, I am currently travelling in Europe and I have a SIM card from a local mobile company. I discovered the hard way that there is an option missing: Settings > General > Network > Cellular Data (on/off). This option is not present in iOS 3.1.3. So basically, you disable 3G but it is impossible to block EDGE, and your phone will automatically revert to it if 3G is not available, and you will occur cellular data fees anyway.
I am sure of what I am saying because with the local service I use, I have unlimited data for $4 per day, but it is debited as soon as I consume one byte of data, then it is free until midnight the same day. Event if I have set Enable 3G = off, Data Roaming = off, for two days in a row, I was still charged the $4 a day because the Cellular Data was not off!
I compared with my wife's iPhone 3GS with iOS 5.1, there is the three options, Enable 3G (on/off), Data Roaming (on/off), Cellular Data (on/off). The option to turn it off simply doesn't exists on iOS 3.1.3!
With some research, I found that it is possible to block it anyway if you change your APN (Access Point Name) to an invalid setting. The easiest way to do this is to connect to the Internet using WiFi, then access this web site with Safari: http://unlockit.co.nz/ (from your iPhone).
This online tool allows you to change your APN, it is very useful when you travel abroad and you use local SIMs. On the first screen press Continue, on the second screen press Custom APN to create an APN for a local mobile company, or press Disable Data (FakeAPN) to disable 3G and Edge for good. When creating a Custom APN, you will be asked to choose a Country and a Provider, then press Create Profile. Then, either way, press Install and "Install Now" or "Replace", then press Done. This will add two things to your phone: first, an app-like icon for quick access to the website http://unlockit.co.nz/, second, a new menu in Settings > General, labelled "Profile", that contains your new APN. Note that it is possible to add several profile information, and some may conflict with each other. Remove those you don't need. Don't remove them if you are not sure!
I hope this works for you!

What is the best method for writing Multicolumn List data to a text file?

I am trying to find the best method for writing the data from a multicolumn list to a text file. Say the list has 7 rows and 6 columns of data. I would like the final file to have the data resemble the Multicolumn List as closely as possible with or without column headers. A sample VI showing how to accomplish this would be greatly appreciated. I realize this is pretty basic stuff, but I can get the output to the file, but it comes out with duplicate data and I am on a time crunch hense my request for help.
Thank You,
Charlie

What is the best method for saving files off of the hard drive?

I would like to save music files and photos somewhere other than my hard drive (eg. CDs, DVDs, zip disks). What is the best method for doing this?

It rather depends on how paranoid you are
External hard drives protect you from hard disk trouble on your machine.
Optical media (CD's, DVD's) protect you from trouble with magnetic disks - such as external hard drives and the HD in your machine. Optical disks are thought to be more reliable that magnetic disks for long term storage.
Off site back-ups will protect you from fire or theft at your home or office.
How paranoid are you? Personally everything is backed up across three diferent external HD's. And maybe twice a year I burn a copy of my photos onto DVDs and they go to a relative's house across town.

I meant RECORDS instead of REGISTERS.Maybe that is where you are going wrong, records are for putting on turntables.

What is the best method for transferring iTunes library from PC to iMac?

Did I just answer this in another post for you?

Quick answer if you let iTunes manage your music: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Start iTunes with the option (shift on Windows) key held down and guide it to the new location of the library.

What's the best method for a nav menu with image rollover for all visitors?

Hi.
First, thanks for reading this.
What's the best method for a nav menu with image rollovers for all visitors, including PDAs? I've used JavaScript rollovers for years because the majority of my customers' visitors use some version of IE (past 7.0) but I'm building a new site that has to display properly for the widest range of visitors imaginable. (I also know that I need to use a more modern method for everyone and this is my excuse to start).
Finally, using images is critical. I apologize ahead of time to anyone I offend, but I have never seen a nav menu without images that doesn't look just plain terrible.
Thanks.

If you want the best menus possible for Dreamweaver look no further than Project Seven:
http://projectseven.com/
They have all kinds of menus and other extensions available for purchase. Easy to use and they work as advertised. I personally use Pop Menu Magic and Tab Panel magic myself. I could go on and on, but I guarantee that if others respond they will echo the same sentiment for Project Seven.

HT1229 what is the best method for using a iphoto with an external hard drive for greater capacity?

what is the best method for using a iphoto with an external hard drive for greater capacity?

Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

What is the best app for storing all passwords in a secure area? osx snow leopard

What is the best app for storing all passwords in a secure area? osx snow leopard

Keychain is nice, but I prefer to use 1Password. It's got a nice user interface, and does what I need. It stores passwords, notes, identitiy info, credit card info, application registration numbers, saves hardware information such as your router settings, and more. It also has a secure password generator. There's an extension that keeps a button in the browser toolbar for Safari, etc., so you can submit your info (password, credit card) with the click of a button, and without having to type the information in through the website you are visiting. It also pays attention when you are signing in to a website, and asks you if you want to save the login to 1Password. Once you get them all entered, it's a big timesaver.

Anyone have any idea which is the best application for taking notes and essay writting?

im starting my first year of university and i was wondering what would the best application for taking notes on be? and also whats the easiest, most reliable and effective way to transfer documents off the ipad? Any thoughts on printing aswell?
will be appreciating all the help i can get!

You're going to get as many answers to that question as there are people to answer it. You don't state if you want to take handwritten notes or if you will be typing. For handwritten notes, I really like Noteshelf. It has lots of export options, my favorite being to Evernote (which you might want to look into as well for storage). For typing notes, I'd go with Pages, Documents to Go or QuickOffice. For working with PDFs, I like PDF Expert.
I've recently heard good things about Note Anytime. It is free for a limited time, so it'st probably worth downloading to try out.

What is the best method for moving iTune Libraries from Old to New Computer

Hello,
Thanks in advance for any assistance you may offer.
My Sony Vaio Desktop recently died and untimely death, so I just purchased an HP Notebook. I was trying to wait out the release of the possible update of the Macbook line. However the old computer didn't agree. This HP will tie me over till a new release.
I've been doing weekly backups for over 3 years with a backup drive from Western Digital. At this point I just want to transfer my music in iTunes and applications from the App store that are loaded on to my iPod Touch into the new computer and then reauthorize and sync.
My question is what's the best method. Oh another problem I'm having includes the latest iPhone & iPod Touch software problem of 3rd party apps not working along with the vanishing of my music on the Touch.
Any guidance would be much appreciated.

Open up a fresh copy of iTunes. Point iTunes in the direction of your Western Digital Harddrive. Import Folders.
1. New Copy
2. Edit -> Preferences -> Advanced -> General -> Change -> <the address of the iTunes library on WD>
3. File -> Add Folder to Library -> <Select iTunes folder on WD>
Always keep a backup of your iTunes Library file and the iTunes XML Document. If you have those, then it might be just as simple as copying those to your iTunes file folder. If you are not sure where they are, then do a search for iTunes.xml.
