• OFA confuses me - why the points for editing data files 3?

  Hello
  
  I met lately about this statement:
  
  Table D-7 shows a hierarchical mapping of files of a compliant installation OFA sample with two directories of Oracle base and two databases. The database files are spread over three mount points, / U02, /u03 and /u04.
  
  
  
  of http://docs.oracle.com/html/B10811_05/app_ofa.htm
  
  My question is:
  Why three mount points (/ u02, /u03 and /u04) for the data files? Don' understant this.
  is it not better to store all the data files in a mount point?

  Although separate mount points don't necessarily mean that they are mounted on different tables, or readers, what examples are involving. Systems are often configured in this way for a number of reasons such as performance or recovery (ie. multiplexing of your recovery logs, or by placing data files for certain tablespaces on their own tables or units). The documentation is illustrating how be OFA compliant in this scenario.

• How can I add data file to an existing table on Oracle RAC ASM with no OMF? Thank you!

  How can I add data file to an existing table on Oracle RAC ASM with no OMF? Thank you!

  Hello

  So I guess you have some files in ASM, see your first existing file structure

  Select file_name

  from dba_data_files;

  and to add to an existing table, the example below (even if you're better sticking with OMFs!)-is that what you are looking for?

  SQL > create tablespace TEST1

  2 datafile '+ DATA' size 1 M;

  Created tablespace.

  SQL > select file_name in dba_data_files;

• A SCN for the entire database and the different SNA for the data files?

  DB Version: 11 g
  
  I always thought that there is a unique SCN for the database as a whole.
  A quote from the link below as
  When a control point is completed, Oracle stores the RCS individually in the control for each data file file
  http://www.dbapool.com/articles/1029200701.html
  
  
  What does that mean? There is a SNA for the entire database, and there are individual SCN for each data files?

  Well, unfortunately, the article says more bad than good things. Or if I can't call them wrong, they are rather confusing and rather than clear things for the reader, its making them appear to look more confused.

  First things, YVERT is used for read consistency (CR) mechanism and the backbone of the notion of Multiversioning. The control point is the mechanism to help that recovery is decided. Contrary to what said article, not any kind of checkpoints update both the data file and the control file, and also, there is not a type of them as well. In addition, the article says that the LAST_CHECKPOOINT is set to NULL, while its actually set to the infinity since it is not possible to detect the moment when the database is opened, that the last issue of control over the file would be. In the case of complete control point, this number is saved and is also associated with the toa Controlfile own database leader at the next startup. If this is not the case, there is an inconsistency in the stop_checkpoint of the data file and the stop_checkpoint reocrded in the control file, leading to a recovery of the instance.

  There are several types of control points. Similarly, there are several types of SNA as well. Without going into the details of these, IMO, the article simply means that when the control point write over a file passes, oracle updates the file checkpoint on it and this is recorded in the Controlifle. as well.

• Enter the value for the data files:

  Hi all
  I use 10.2.0.1.0

  now what I hv value to enter? or how to calculate the value.
  
  
  Thank you

  Honey says:
  Yes I know its 'AND' but when I using the '&' then oracle asked me of ' enter the values of the data files: "k".
  Please try first, then the calculation of the value.
  It can be a variable binding value.
  If you find the answer please suggest steps

  Simple words, the "DROP TABLESPACE" command does not support '&' character. & is a substitution of placeholder for SQL variable * more.

  Even if you provide the value for the "data files" prompt, the command does not work as it would lead to "drop tablespace including contents tsname *"details of your file *.

• How to move data files from drive C to drive E in MS SQL Server 2005 used for hyperion

  Hi all

  We have installed Hyperion with MS SQL Server 2005. Hyperion 11.1.1.3 works well.

  But in the SQL server data files will register in C drive only. But we have to back up the files in drive E.

  I used the Attach and Detach method to move files from C drive to E drive.

  After that, I am reconfiguring the EPM system. but I get errors in the configuration.

  Now I get the planning of database failed when Confiuring planning.

  Configuration of data source interface has failed in the Configuration of EPMA.

  Please suggest the best way to make this scenario.

  
  

  Thank you

  Why do you need to reconfigure after that move data files, if it is done properly it should be without data loss.

• How to select a data file of a folder for Sqlldr during execution

  Dear all

  I use the client to Database 11g Rel.2 on windows 2012 server with database 10g Rel.2 on another server.

  I get text files pipe-sign separated from a third-party software in a specific folder on my client machine.

  This 3rd party software exports data files after every 30 minutes with the naming convention of names like "Filename-Date (YYYYMMDD) _Time (HH24MI)" like this:

  TestData-20150408_0935

  TestData-20150408_0905

  TestData-20150408_0835

  ....

  and so on...

  I tested and successfully imported data using Sqlldr to my client computer in the database, but only with a specific name like "testdata".

  I don't know how to import the last file generated with the Date last time.

  You people can give me a solution to handle this situation?

  Thanks in advance.

  Again, this has nothing to do with Oracle. Can't you see it's not variable environment, latest is empty. Output shows clearly part of batch D:\export\%latest% file in translates into D:\export\

• Prepare disks for ASM (data files and FRA)

  I intend to place data files on a disc 1 (sd1) and disk2 (PSD) when the backup of files (FRA) on disk3 (SDC). Here's how I'd do:
  
  For data files
  Disk1 is divided into a single primary partition (with native Linux what ID 83 not formatted system)
  Disk2 is also divided into a single primary partition (with native Linux ID 83 system not formatted)
  
  oracleasm createdisk vol1/dev/sda1
  oracleasm createdisk vol2/dev/sdb1
  
  CREATE DISKGROUP DATA EXTERNAL vol1, vol2 REDUNDANCY;
  
  
  For backup FRA
  
  Disk3 is partitioned into four primary partitions: / Boot (ext3), / (ext3), swap (swap) and /u01 (ext3)
  
  The FRA will be put under the/U01 and then attend the ASM:
  
  oracleasm vol3/dev/sdc4 createdisk
  CREATE DISKGROUP DATA EXTERNAL vol3 REDUNDANCY;
  
  Now, the problem. (1) the/U01 has already be formatted in ext3; (2) Oracle (DBMS) software will also be place under/U01
  
  It will be a problem?
  
  
  Otherwise, I can put FRA on the same drive as the data files, i.e. on disk1 and disk2. In this case, I need to partition the disk 1 in two primary parititions sda1 and sda2 (native Linux system ID 83 not formatted), one for data files and another for FRA (do the same for disk2). The downside is that the data file and the file recovery will be on the same hard drive.
  
  
  Please offer some suggestions.
  
  
  Thank you
  
  Scott
  
  PS: in the environment of production, all the disc 1, 2 and 3 will be on hardware RAID 1.

  RAID 1 will protect you only a device failure. It won't protect you partition, the file damage system or user errors; It will be in the image of the errors and problems like any other data.

  So what happens if you delete by mistake / U01 or some other accident happens and you loose that partition? With your current setup, you will lose everything and will not be able to restore or recover the database. Put tablespaces FRA and DB on the same physical device is certainly a very bad idea, whether or not it is a RAID.

  ASM is not a software RAID 1 mirror. It ensures redundancy of data based on file extensions and knows about files of Oracle database, which is a very good thing. You probably do not want to specify 'external redundancy.

  In a production system, you'll certainly want to mux the critical data and to store the DB controlfiles, redo logs and finally archivelogs on media separate physically in order to avoid the single point of failures wherever possible. You can use partitions and volumes in ASM, but they should be separate physical drives, otherwise you will bypass the ASM data redundancy. You must also have a solid strategy for RMAN backup. The FRA is supposed to store backupsets RMAN, copies of the image, the important archivelogs and multiplexes of the copies of the database files and should therefore always on a separate physical disk.

  Unless you simply play, I strongly suggest that review you your current configuration.

• during an update lots of my profile folder has been put in a folder on the desktop marked the old data. How to restore this data file

  During a bet to update, automatic update of windows has started and some how much my profile data has been removed and stored in a file on the desktop. There is a simple and easy way to restore this folder from the current firefox?

  You can use the contents of the Old Firefox Data folder to "roll back" the refresh, but this involves several steps. It's probably even faster than the recovery of individual files and load those into your new profile.

  Check in the folder 'Old data Firefox' update adds a folder with a random semi name on your desktop. If there is only one, that probably has your old settings and Add-ons. If there is more than one, you'll want to work with one who has been updated recently.

  Once you have identified the profile folder, that you want to restore, here is my "old profile resurrection suggested procedure:

  Overview

  Here are the steps described in more detail below:

  1. Create a new Firefox profile
  2. Delete all of this profile folder
  3. Copy in all of the old profile folder

  Create a new profile for Firefox (Windows)

  Exit Firefox completely and start up in the Profile Manager by pasting the following in the Windows search, or the Run dialog box by pressing ENTER:

  firefox.exe -P
  

  Note: any time want to switch profiles, exit Firefox and return to this dialog box.

  Click on the button create a profile, give it a name like OldSettings and skip the option to change the location of the folder. Select the new profile from the dialog box, and then start Firefox.

  Open the new profile folder in Windows Explorer

  Firefox in the new profile should look like a new installation of the plant. Open the troubleshooting information page by using either:

  • button "3-bar" menu > "?" button > troubleshooting information
  • Menu help > troubleshooting information
  • type or paste everything: in the address bar and press Enter

  In the first table, click on the view file"" button. Firefox will launch your new profile folder in Windows Explorer.

  This folder open, switch back to Firefox and get out by using either:

  • "3-bar" menu button > button "power".
  • (menu bar) File > Exit

  Firefox is closed, the profile folder must be front and Center, or you can activate it by using the taskbar.

  Copy old data instead of new

  In this new profile folder you just popped open - NOT the one on your desktop - select all content (you can use Ctrl + a) and delete (you can press Delete on the keyboard).

  Leave this window open, open or switch to your folder of old data of Firefox. Consult your old profile folder. At this level, you should see a folder named bookmarkbackups among other things.

  Select all (Ctrl + a) and copy (or right-click > copy or Ctrl + c).

  Switch to the empty profile folder in another window and paste (or right-click > paste or Ctrl + v). This may take a few minutes because some files are large.

  Launch Firefox

  Firefox should start in this 'new' profile with the old resurrected profile data. Success?

• Defining the new path for the data files for restoring using the VALUE of NEWNAME FOR DATABASE

  Today, I had to do a restore RMAN to a new server and I came across the post following RTO on the VALUE of NEWNAME FOR DATABASE

  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -----------| Holy Cow |-----------------------------
  
  
  So I had to rename each file as below
  

  $ mv 1 /fnup/hwrc/oradata/spikey/system01.dbf
  $ mv 2 /fnup/hwrc/oradata/spikey/sysaux01.dbf
  $ mv 3 /fnup/hwrc/oradata/spikey/undotbs01.dbf

  I would have been better in execution of the order for each data below file

  SET NEWNAME FOR DATAFILE

  Now, I think, there is no advantage in using NEWNAME SET of DATABASE to. Only the disadvantages. I did anything wrong above?

  Martin;

  On the issue of the VALUE of NEWNAME FOR DATABASE, you must specify at least one of the first three of the following substitution variables to avoid collisions of names: %b f % U. see semantic entry for TO 'filename' for a description of the possible substitution variables.

  You use %f

  %b
  
  Specifies the filename without the fully qualified directory path. For example, the datafile name /oradata/prod/financial.dbf is transformed to financial.dbf. This variable enables you to preserve the names of the datafiles while you move them to different directory. During backup, it can be used for the creation of image copies. The variable cannot be used for OMF datafiles or backup sets.
  
  %f
  
  Specifies the absolute file number of the datafile for which the new name is generated. For example, if datafile 2 is duplicated, then %f generates the value 2.
  
  %U
  
  Specifies a system-generated unique filename. The name is in the following format: data-D-%d_id-%I_TS-%N_FNO-%f. The %d variable specifies the database name. For example, a possible name might be data-D-prod_id-22398754_TS-users_FNO-7.

• Convention of file name for the *.dat files

  My colleague gave me several *.dat files created by LabView.  They have names like Data2_11119_40866.dat.   I think that the strings (11119 and 40866) could contain information about the time covered in the file.   If so, this information would be useful for me in the treatment of the data.

  Can you please point me to a reference that explains the naming of *.dat files mode in LabView?   As you can tell, I am not a user!

  Names of files are created by the programmer. It would be best to ask them what are the meanings of the names.

• How to remove the .dat files

  Hi all

  I recently updated my Surface Pro and I noticed that during the update, there is a Windows.Old folder that contain data from before the update. However, when I tried to remove this folder as the update seems to be normal, I am unable to remove 6 boring. DAT files that remain. The. DAT are associated with an app called Kno manual and some are associated with Studyblue.com that allows me to generate and store the flashcards online.

  6 of these files have file names that are ridiculously long with weird symbols two SS in the midst O...

  Whenever I try to delete these files, I get an error saying "file names are too long for the destination folder. You can shorten the file name and try again, or try a location with a shorter path. »

  I'm unable to rename these files, send them to any location or compress them, basically, I can't do anything with these files and I can't delete the entire folder Window.Old.

  Is there a way to delete these items?]]

  Thanks in advance

  Well, after a lot of research I thought it

  Forget the noise on the Unlocker download, FIleAssasin, ETC..

  Best way to do this is through the command prompt.

  Open cmd prompt, type:

  DEL/p/f/s/a "C:\Windows.old\*".

  And viola, it has deleted the. DAT files and I was able to manually delete the Window.old folder.
