• DB always upward after losing a data file

  DB version: 10 gr 2
  OPERATING SYSTEM: AIX 6.0
  
  To test a scenario of recovery, I backed up the entire database and deleted the users01.dbf data file. I thought that the PB will crash. There can be no.

  select file_name, tablespace_name from dba_data_files where tablespace_name='USERS'; 

  which showed that exitsts file! I tried a few insertions, updates and REMOVE with commit. They all work! You can even create table instructions worked.
  
  Then from
  But deleted data file accessible data
  and
  Removed datafile always online?
  I got to know that he is the expected behavior in UNIX environments.
  
  My questions:
  
  Question1.
  After a fall users01.dbf file, I had done several LMD with COMMITs and CFDS. where the process of Dbwriter wrote these changes when there was a control point?
  
  
  Question 2.
  Database became aware of the missing data file only when I put the datfile offline and then tried to put online.

  SQL> alter database datafile 'u07/data/oraqa215/users01.dbf' offline;
  
  Database altered.        
  
  
  SQL> alter database datafile 'u07/data/oraqa215/users01.dbf' online;
  alter database datafile 'u07/data/oraqa215/users01.dbf' online
  *
  ERROR at line 1:
  ORA-01157: cannot identify/lock data file 4 - see DBWR trace file
  ORA-01110: data file 4:'u07/data/oraqa215/users01.dbf' 

  Why is the DB still even after DB learned that users01.dbf was absent?

  Some important points in my opinion:

  Terminology: Apparently, you do not "drop" the file with a SQL command. Instead, you removed it with an OS command, which is a major difference. Select on v$ datafile and DBA_DATA_FILES will always show the file still being included in the database -has nothing to do with handles still open etc but is normal behavior.

  Availability: The instance not crushed after your deletion - what is very good and no reason to complain. Your users will appreciate that, especially those who do not need the tablespace, associated with this file. If DML is going through, it will record the vectors of change in online newspapers, used later in the recovery process to find all the transactions are committed. In other words: you will lose any committed transactions ins spite of your deletion of the file. Again, it is very good and no reason to complain.

• How can I get the music in iTunes? After saving my iPhone on a new hard drive, how to make music in iTunes?

  I'm trying to get songs from my iPhone to my macbook pro ' after saving my iPhone on a new hard drive, I want to put these songs on iTunes

  Your i-device was not designed for unique storage of your media. It is not a backup unit and transfer of media has been planned with you keep a master copy of your media on a computer that is itself saved separately against loss.  To use a device with a different configuration, you pass the old library from a computer or a backup directly in the new configuration, not the device to the library. Synchronization of media isn't a way, computer to the device, update the contents of the device to the content on the computer, update or restore the content on a computer. The exception is iTunes Store purchases that can be transferred to a computer.

  Redownload or transfer your iTunes Store purchases an iPhone, iPad or iPod to computer - https://support.apple.com/en-us/HT201267 - 'this feature only works for content purchased from the iTunes Store. From iOS9 is more apps that now need to be re-downloaded directly from the store.

  To transfer other items from an i-device to a computer, you will need to use third-party commercial software.  See this document in turingtest2: recover your iTunes library from your iPod or device iOS - https://discussions.apple.com/docs/DOC-3991 even this method can fully recover what you originally had in the library. For example, in order to save space during synchronization if you had converted music files at a lower rate, or photos at a lower resolution, it is these lower quality files that will pick you up.

  If you subscribe to the Apple music, titles that are not part of the content that you have purchased or downloaded may not be transferred and must be downloaded directly from iCloud.

• After Vista update cannot find the external hard drive, AutoPlay does not work, and new unusable disk appears under my computer

  After Vista update cannot find the external hard drive, AutoPlay does not work, and new unusable disk appears under my computer. Also I can't 'manage' my computer because I do not have "permissions". I tried a fix he 45071 and it did nothing.

  Applications, (Norton and McAfee) (including free evaluation versions are notorious for not not upgrade (or uninstalling) itself.) If NIS has been installed for 3 years, you have NIS update at least once and maybe twice (e.g., NIS 2009 > NIS 2010 > NIS 2011).

  [You may want to print these instructions for reference offline. If a step said to reboot, reboot.]

  1. download the Norton Removal Tool, save it to your desktop: ftp://ftp.symantec.com/public/english_us_canada/removal_tools/Norton_Removal_Tool.exe

  2. close all open applications (that is, anything with an icon on the taskbar).

  3. After completing some you have a copy of your handy product key, uninstall all Norton software (including LiveUpdate and everything Norton Add ons) viaControl Panel | Programs | Uninstall a program (or Control Panel |) Programs and features, if you are using the classic view).

  4 IMPORTANT! -Online activate Windows Firewall immediately after the restart.

  NB: Now you're "working without a net": no to ANYTHING else online (e.g., navigation, reading e-mail, chat) until you have completed step #7 below!

  5. right click on the file that you saved in step #1 above, and then select run as administrator.  DO TAP not your keyboard until the race ends, then restart.

  6. do a clean install of NIS 2011 (using your product ID, if need be) & reboot. CF. http://www.symantec.com/norton/support/kb/web_view.jsp?wv_type=public_web&docurl=20080514162318EN

  NOTE: Do NOT activate or install additional modules of Norton (for example, Norton Anti-Phishing) immediately.

  7. manually and repeatedly run LiveUpdate (Norton) until you get a prompt "no update more".

• Restore files using external hard drive

  I have an external hard drive which has my files my desktop which is Windows 7.  This office has crashed and I need to put the files on my laptop that is Windows 8. Is this possible?

  Hi Julie,.

  Thanks for posting your query in Microsoft Community.

  Yes, you certainly can restore all of your files from external HDD (HARD drive) to Windows 8 regardless of the version of Windows that we put them on earlier. If you have some backup software, you can restore the files using your favorite backup provided by the external HARD disk manufacturer software. If the data contain documents, images, or other media files, you can directly move files in the HARD drive files external to the library folders in Windows.

  Hope this information is useful. Let us know if you need more help, we will be happy to help you.

  My laptop is running out of space so I need to transfer the games mainly from my laptop on an external hard drive.   What are the steps to achieve this?

  Go to computer stores, get an external hard drive of 1 TB capacity. Ask for one that you can just simply copy and paste to transfer files.

  I have a. Digital WD Elements. 1 TB vapacity. It works very well. No action of fancy, complicated to transfer, just copy and paste or drag and drop files.

  I also use it to make Sysytem Image backup.

• Displacement of Vm data store on a hard drive and restore at a later date

  Hello

  I'm working on a newly created virtual environment that is used to create areas of base to be used in demonstrations for new businesses.

  We have run out of disk space but need to urgently create new servers for a new demo. I would like to delete some exisinting VM from the data store on the hard drive of a computer in my office and then put them at the time where we have increased the disk space for the data store.

  Please can anyone provide me with some step by step insturctions how to move the virtual machine on the store data and on my machines, and then the process to get back them.

  Versions of the software appear in the attached file.

  Thank you

  Andy

  There are several ways to achieve your goal.

  In my opinion, the simplest is to use the browser of data store in the vSpere Client and download the VMs/folders.

• Help! I need to extract audio from a video to an audio file in my HARD drive

  Hello

  I have a project that needs to me mastered (the audio part at least), and I need to extract the audio parts of my sequence in 'physical' files on my HARD drive, so I can load my project (with these separate audio files) on another computer where the control will be done... but I can't do it! .. is there anyway I can do this?

  Help, please!

  Thanks in advance...

  Al

  You can select an avi clip and right click, then choose Edit in Soundbooth. This creates a wav audio file in the clip, with the same name as the video clip with "extract" added automatically.

  Also, it replaces the audio in the sequence with the extracted file, but does not change the original item.

• Restore a specific full backup of data file to a new location

  Hello
  
  I have a test instance (10.2.0.4). I took a full backup of the database and has fallen to a data file.
  
  Now, I created an auxiliary Instance where I restored the controlfile since the full backup to help:
  
  RMAN > run {}

  Restore controlfile to ' / home/rtest/aux/control01.ctl';
  }
  
  Now, what is the procedure to restore the deleted data file in ' / home/rtest/aux/***.dbf';
  
  Help, please.
  
  Thanks in advance.
  
  Kind regards.

  You can 'Transport' the Tablespace containing the datafile after completing the Point in time of recovery on the auxiliary.

  All data in the tablespace must be made up - for example, you can't FKs referencing tables in other storage spaces.
