ASM files and backups
We are setting up new machines with the intent to eventually start using RAC so I am planning on using ASM. I was reading Oracle's "Automatic Storage Management Technical Best Pratices" and there is a statement that says "database backups of ASM files can only be performed with RMAN" . Our UNIX admins (as part of this project) purchased a product "HP Business Copy EVA" with the intent of using it to do Oracle backups very quick.
Does anyone have any experience with "HP Business Copy EVA" ?
Does anyone backup ASM files without using RMAN?
Can anyone explain why Oracle's paper makes this statement?
We are in the process of implementing a 10g RAC solution now. We started out using ASM and ran into a number of problems including some memory leaks on the ASM instance. We switched to OCFS and system has been running without a hitch for a month. Good thing here is all the old backup scripts function. Do not need to use RMAN if you really don't want to.

How to remove Database Files and Backup from ASM
Hi All,
Oracle Database 11.2.0.3
OEL 5.7
We have a host for restore purposes.
We execute monthly or quarterly restore operations to verify that I am able to restore a subset of the data in the given amount of time or to other purposes.
I have a automated script to Clone the Database, but to Clone Database we need remove the old database from ASM before start this operation. I want remove only Database files and keep the configuration (such as oratab/network/ocr and so on).
Question: There is a easy way to remove these files without connect on ASM or by using DBCA?
Appreciate any helps.user12028775 wrote:

Yes... there is a easy way. Use command DROP DATABASE.
Use the DROP DATABASE command to delete the target database and, if RMAN is connected to a recovery catalog, unregister it. RMAN removes all datafiles, online redo logs, and control files belonging to the target database. By default, RMAN prompts for confirmation.
Put this command on your script before clone your database:
RMAN> CONNECT TARGET SYS@test1
RMAN> STARTUP FORCE MOUNT
RMAN> SQL 'ALTER SYSTEM ENABLE RESTRICTED SESSION';
RMAN> DROP DATABASE INCLUDING BACKUPS NOPROMPT;Regards,

Store to file and backup at same time
Hello!
We have a very well working measurement software written in LabView. However we would like to backup the data files regularly. We want to be able to do this even during measurement and while the software is writing to the files. Now when we try to do so, we occasionally face "Error 5 occurred at Open/Create/Replace File" (in "Write To Spreadsheet File") because another software (backup, windows stuff, else...) accesses the files also. Now from my point of view this kind of concurring file access should not be a problem since LV is the only software writing to the files. There are 3 possible solutions I can think of:
delay the write (not feasible since you don't know how long to delay, e.g. how long the other software stays open)
queue the data and write it on next try (e.g. https://decibel.ni.com/content/docs/DOC-7212 - but again; how long to queue?)
the proper thing is; copy the file to a temporary one, edit the temporary, delete the original and move the temp. in this place
the last one should be the proper solution and also work on different OS since the copy/moving stuff should be atomic operations and thus safe in this context. However I implemented the solution and still have exactly the same problem but now in "Move File"... I am starting to doubt if it is possible to solve this issue at all and thus desparatly need help here! As I can see there is not lock or mutex on the file and no need for LV to raise an error (I think it is done as warning for future possible conflicts)... I assume it is some hidden/strange badly documented Windows API "feature" LV is using to detect those other accesses and it results in a behaviour I cannot change or fix - so what to do here...?
Thanks a lot in advance for any helpful suggestions or hints! Greetings

Solved!
Go to Solution.I Think you must have missunderstood me; the problem is you cannot open and write to a file while another external program has it opened too with exclusive access. Consider following code:
If you open the file during the "Wait" (it is closed then because "Write to Spreadsheet" does open, write, close) e.g. with MS Word wich does an exclusive open (allowing exclusive access only) then during the next loop your program will crash with error 5.
The solution I mentioned is to open it first in LV an keep it open all the time:
which prevent e.g. MS Word to open it exclusively but read-only!
What you mentioned is regarding a backup - I considered this double write long before, but it is no good solution, beacuse e.g. the other drive might be a network drive and I don not want to handle absent drives - that's something the external backup tool should do. -
IPhoto file and backup strategy
I am new to iPhoto in last 9 months, but before I get in too deep, would love some advice about how I am structuring the library and about my backup strategy.
Spent many years on Windows where I would use a typical file Windows file structure. Broke my pics down into years, then events, then pics. Some pictures I would rename "Ella Bday 2006" and others are simply "jpeg-10006". When I moved to the Mac, I've started to use events "Ella Bday 2008" or else "Jan-Mar 2009". I've read that many prefer to create albums and not rely so much on the events. I am not there yet, but that's my next goal.
My questions are multiple. First, what is the best way to backup all this data so that if I crash, I can easily recreate? I backup the windows files in the same file structure as they existed on my HD, but with photos, events, albums, etc I am not sure the best way on the Mac.
I did import all the windows pics into iPhoto -- so now I have a single app for all photos dating back to 2004. I am not using Time Machine (remember I am a newbie) at the moment, and my initial plan is to back up each year to a separate DVD for off-site storage. Once this is done, I will look for a more permanent and recurring backup strategy - Time Machine I suppose - that will use an external HD.
Sorry if my post is convoluted, or if my questions are ignorant, but I was a lifetime Windows guy who is just exploring all the features/functions of Mac -- so any advice or redirection would be fantastic!
Thanks in advanceFirst, what is the best way to backup all this data so that if I crash, I can easily recreate?
Make a copy of the iPhoto Library in your Pictures Folder. That gets all the photos and database files which contain your organisation.
If you want to burn a copy of the Library to DVD use the Share => Burn command.
FWIW here's my back up system. I used to use DVDs but it was too tedious and a bit expensive too. Remember, if you burn, say 2005 to DVD ths year, you will be burning it again in a couple of years as DVDs to degrade over time.
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. For this job I use DejaVu because it makes a simple back up that is clear and can be tested easily without doing an full restore.
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. Personally I use SmugMug but there are many options including flickr. 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 will 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 restore.

Hi,
I have a timecapsule and would like to use it to 1)store files to be accessed anywhere on the net (im guessing this means using it with backtomymac?)
and 2) use it for the timemachine backups
These processes are each used by a different user (one wants backups and the other file access)
Is this possible and secure?You can do both..
Accessing from the Net is not as easy as it sounds.. but there is plenty of info around..
Starting here.
AirPort Disk - Remote Access (3 Methods)
You can backup your TM to the same TC.. but encrypt the backup otherwise anybody will be able to access it.. once encrypted they can still access it but they cannot read it. Nor can the person it belongs to if they forget the password.. so this is important to store the password in some secure way.. aware that without it you may as well have not even bothered. -
Can I automatically save a file and backup at the same time?
My financial files are held in the cloud which means time machine does not back them up. Is there a way I can automatically backup the files whenever I save them?
Anyone? Even if only to say it can't be done.

What is the best way to create additional storage AND backup a laptop, as well as the storage?
Beyond being seriously annoyed at an Apple Employee recommended we go the NAS route at an Apple Store no less—only to find it doesn't work for storage OR Time Machine backups of iPhoto (after spending weeks organizing/transferring date, outside of a good deal of coin)—we are now perplexed as how to set up/store based on our needs.
Goals
Create additional storage (iPhoto, iTunes, documents) for the family laptop
Accessible by anyone/device on the home network (iPad, mini iPad, iPhones, etc..)
Would prefer the ability to access this offsite as well
Backup of the laptop
Backup of the storage HD
Ensure we do not lose iPhoto libraries data/files
Here is what I am thinking—need to know if it will work.
Purchase two HDs
Plug them into my base station
Allocate one HD @2T for storage (additional iPhoto libraries, home movies, iTunes libraries, etc...)
Partition the second HD @3T to handle two Time Machine backups
(a) Time Machine of the laptop (up to 1T of backups)
(b) Time Machine of the first HD (up to 2T of backups) - Is this possible?
What I need to know is
Is it possible to partition a HD to Time Machine two backups from different sources—one being a HD?
If this is not a good solution—what is? I am pulling my hair out trying to figure out how to deal with a lot of data related to iPhoto due to the formatting limitations there.While most do not advocate mixing Time Machine backups with other files, I have 3 Time Capsules with files and backups on the same partition and have never had a problem despite doing it for many years. All 3 Time Capsule are set up as NAS devices.
One Time Capsule holds the Snow Leopard partition backup of two computers. The other two each have a backup of the Mountain Lion partition of two computers. Time Machine is set up to alternate between the devices, which it can now do. On these 2 Time Capsules is a copy of the iTunes Library and a copy of the iPhotos Library, which provides a backup for the two. Every so often I manually copy the new files from the primary iTunes/iPhotos library to the backup on the other Time Capsule.
If the computer is on, I can access the computer from my iPad and then access the hard drives and the files.
Hopefully, I have been able to make this clear. -
Control file and spfile auto backup backup is failing
Hello All,
I am using Oracle RAC 11gR2 with ASM. My database is 2 nodes RAC1 and RAC2.
I am taking RMAN database backups to ASM diskgroup (FRA) and to a Network File System mounted on both RAC1 and RAC2. I have this requirement to take backup also outside ASM.
I have set: CONFIGURE CONTROL FILE AUTOBACKUP ON;
I am runing the RMAN backup job from node 2 (RAC2)
I am facing the below error when taking a backup to the Network File system;

So basically I tried to back up my itunes library to my external hard drive and when I followed the instructions and then went to play a song it said Orginal file cannot be found. It said that for all of the songs. I'm not sure how to fix what I did, I already tried consolidating and all of that stuff and it didn't locate the files. I'm guessing that I somehow deleted the original songs along the way. I synced my iPhone without knowing what I did and surprisingly all of the music is still on my phone. So now that I've completely screwed up my iTunes account, I need to know how to get all my music back onto my iTunes account and have that library only on my external hard drive, not my computer. Everything looks fine on my iTunes besides the fact that it cannot locate the files but what I'm afraid of is me syncing and backing up my iPhone and then being left with no music because it syncs to the empty songs. How can I fix this? and if I can't fix my iTunes library is there anyway for me to still be able to backup my iphone and all the music on it, without erasing my music?
Well I'm not sure if I correctly backed up my itunes library because when trying to open itunes from that back up it keeps saying original file not found. Okay this is going to sound confusing but bear with me. I "backed up" my itunes, meaning I just dragged and dropped the iTunes folder into my external hardrive, and then I changed the destination on iTunes to open from my external hardrive. It was working fine when I did that, however I did that just on my own, I didn't know about consolidating the files or any of that so I hadn't done that before copying the folder to my external hard drive. I can't remember but I'm pretty sure I deleted the iTunes folder after I had copied it to my external hardrive. So I did that and it was working fine, I was able to open my itunes with my external hardrive. BUT yesterday I thought that I hadn't done it correctly because I didn't consolidate the files and all that, so I wanted to be more thorough and do that, I followed the steps to do that but when I did that I think it got all the files from my computer and not from my external hard drive so it basically didn't find anything on my computer because I had deleted them. And like an idiot, I replaced the iTunes folder on my external hard drive (the one I did correctly the first time), with the one I did wrong. So I believe I pretty much deleted all the music files from both my external hard drive and my computer. Please correct me if I'm wrong?
I believe getting all my music back on my itunes is a lost cause. BUT I still have all my songs and stuff on my iPhone. My question is, if I plug my phone into my computer and sync it, will it erase all my songs from my phone? A little more info, my iTunes still has the names and stuff of all my songs, they just can't be played because the files are missing, my iPhone doesn't need to erase and sync when I plug in my phone because it's already synced to my computer. What I'm afraid of is when I plug in my phone to backup and sync, will it erase my music because it can't find the files on my computer or external hard drive anymore? Or will it just leave the songs because they're already there (on my phone) and only sync the new songs that I've downloaded? I just need to know is my iTunes still going to be functional as far as me being able to backup my phone?
I have a lot of songs purchased from iTunes but a lot (like 60%) are from CDs that I no longer have. So re-downloading my music would only account for 40% of my library. -
I'm concerned that my iMac, purchased 5 years ago, is about the crash and I can't back up my files and programs to an external hard drive via Time Machine because the computer freezes after only a couple hundred MB and gets nowhere near the required amount.
How can I save these files and programs if the computer hard drive fails or has to be replaced without the backup being able to be done? I need to do something quickly, but I'm not sure what I can or should be doing.Get an external hard drive, some good ones that I like are the OWC, http://www.macsales.com Mercury Elite Pro drives...they are very good and reasonably priced.
Get the drive, connect via USB or FireWire, then use Disk Utility to format the new drive as Mac OS X Extended (Journaled), and then use Disk Utility to Restore the current drive to the new drive. Restore actually clones the drive so you will have a bootable backup on the external drive.
After you have formatted and named the external drive, click Restore in the main Disk Utility window, drag the name of the old hard drive to the Source box, and drag the name of the new external drive to the Destination box. DU will make an exact clone of the internal drive on the external drive.
That clone will be a complete backup of the operating system and all of your data.
You can test it by restarting the iMac and hold the Option key. That will give you a grey screen showing all bootable drives. Just click the external drive, then click the upward pointing arrow under it and the iMac will boot from that drive. -
I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work.
^^ that's the main problem. Here's the full history.
I bought a new 13" i5 MBP, early 2011 edition. I had an old white Macbook 2.14 ghz core2duo on Snow Leopard. I attempted to port over my time machine backup, but encountered problems in that my User was inaccessible from the new computer after the import finished, and I had to go in and change the root password, etc, and for some reason or another, I couldn't install any programs at all from that administrator's account. By "couldn't" I mean I could install them, but upon installation they would never boot. So, I took it to the apple store and did a clean install from the most up to date Lion OSX. Then, I created a brand new admin account, instead of trying to import the old one, and things seemed great. Then, I just imported my old files from the TM backup, but not any system settings, permissions, or user data. Just my Docs, pics, vids, apps, and itunes stuff.
Here's where things get weird again. I imported this stuff under the name "old", but all of these folders have a red negative sign on them, marking them as restricted. So, from my main admin account, I cannot even peruse these folders. Since I didn't import user data, I can't sign in to the "old" account to change permissions. I already tried to change the permissions from system preferences, but that didn't change anything. And now, for whatever reason, of all the apps that were imported then, MS Office is the only set of apps that does not work. When I click on it, it just says there was a problem and asks if I'd like to send a report to apple. I tried reinstalling it to no avail. I'm an English student, so i really need access to Word. Can anyone help? The Apple store is a major detour for me and would like to fix this issue myself.Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.) -
The last few days I have been constantly saving my file. A couple of hours ago I renamed the file and then reopened my file a little while later, but the most recent work wasn't saved even though I'm sure I saved it before closing. What can I do? Also, when I have tried to email it to myself as a backup, the fields aren't populated when I open it up. Fyi, I have the free subscription.
Hi Constance,
As i understand your changes in the pdf were not saved...Are you still facing this issue?

My iMac just crashed, and I had some documents open in Pages that were unsaved. Is there a temporary file or backup file that I can access as on a PC? (I have just looked in Timemachine which I had operating, but it did not seem to have any temp files in it at all - not sure what it would be useful for then).
Any suggestions?Question asked and answered several times.
If you didn't save, nothing is recoverable.
iWork apps don't create temp files so, as far as you on't save something, Time Machine can't archive it.

I have an external hard drive that was formatted by a PC and has files and directories copied to it etc. I want to use it on my IMAC for backup. I see it on my my IMAC . I can open files etc. But I can't seem to write to it nor can I delete current content. I don't care if I lose current content. How do I initialize it for use with the MAC?
You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:
http://www.macupdate.com/app/mac/24481/ntfs-3g
If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.) -
How can I get back a pages file and its backup if I did not save them to my documents?
Hallo community!
My mac got stock on a website because of a java update so I was forced to shut down the computer using the on-botton. Upon restarting my work on Pages I clicked on the file I was working on so as to open both the file and pages but the file wouldnt open. I checked if I had also saved the file on my documents to try to restart it from there. But this file comes originally from a USB which I dont have at this moment although I could kee on working on this file without the usb. The file is not my documents yet it shows on the last files-list of pages.
I cant open this file anymore, maybe because I did not save it to my files. Although this is strange because I even named another file I worked on along this first document. Enfin, the first file even has a backup according to the list but the backup wont open either. I don't know how to get this file back I am in big trouble If I dont get to open it soon! I hope somebody can help me. Anyone knows a trick or something!?What version of Pages?
It sounds like it may be damaged.
You do not have to save to Documents.
