Question about the impact of a data file missing

Oracle Version: 10 gr 2


If a data file (not a data file belonging to the tablespace SYSTEM or any other data file associated with Oracle Internals) is lost, I can bring the database up somehow?

Keita,
What happens if I don't have a backup of the data file that is lost?

OK understood

If you do not have a backup of your database and that you have lost a data file, then you must re - create control file (which will contain the names of data inside files) without indicating lost data file name

You must create the controlfile creation script and remove the line of lost data file name and create a controlfile. After that, you should be able to open your database successfully

  • Questions about the collection of personalization data.

    I am currently working on a form which is presented as an xml file using a submit button by email.  There are several things that I wonder if you can customize and if so, how?

    1. Is it possible to have the calculated time field that is included in the exported data?
    2. IF SO... Is it possible to change the date/time calculated field to calculate when the e-mail button is clicked rather than when the form is started?
    3. Is it possible to have the file by e-mail named something other than * name * _data?  Maybe something that includes the date, or another domain specified for point more precisely what form it is?
    4. Finally, is it possible when you import data to import xml data into an Excel file which already has other data collected in it?

    Responses to the foregoing would be greatly appreciated!

    Thank you!

    Kayla

    Hey Kayla,

    Yes, most of it is possible.

    1: select the date/time field and go to object > tab. Liaison depending on the version of LC designer you have, you want the drop-down list of data binding to have 'Normal' or 'using the name '. This means that the value is exported to the XML file. If the drop-down list says "No data binding" or "None", the value will not be exported.

    2: the date/time field probably has the script initialization or docReady. That's fine, the date and time will be filled when the form is opened. In order to refresh the time at the time wherever the user submits the form, you must include the following line in the mouseDown event of the submit button.

    DateTimeField1.execEvent("initialize"); 
    

    This will trigger the DateTime field Initialize event and update the date / time just before submitting the form.

    3: it's tricker, the name of the XML file is set automatically to reflect the name of the file of the form. You can write the script to change the name of the file of form (and by extension the name of the XML file), however, this requires a function of trust in a separate javascript file. This JS file will have to be on all computers which would be used to access the form and to be honest not worth the (significant).

    4: adobe do a good job, if you are distributing your form via Acrobat.com. Additionally, Acrobat version 9 allows you to select the individual xml files and export them to an Excel spreadsheet (under the menu options). You can also compile returned forms by selecting the answer file and the individual xml files. I don't think that you will be able to export a new XML responses in an existing worksheet. Using Excel, you may be able to import the new XML into the existing file. If all else fails, I export the new xml to spreadsheet files, this open in Excel and copy the data back. Open the existing worksheet, and then copy the data back at the end of the table.

    Hope that helps,

  • A few questions about the use of a XML file to add text in a component defined in HTML TextArea

    I use AS2 in Flash CS3.

    I have a TextArea component in the scene that load its XML text and I was able to use the ul and li tags to create lists. However, when I try to include a nested list, he inserts just a line break between the nested list and the main list rather than he dash away. Is there a solution for this problem?

    Otherwise, how would I be able to add spaces nonbreaking in the XML so that they will be inside the TextArea element? I tried and & #160; without success. I've been searching the net for some help with this and find information about the change of the incorporation of xml file with a new entry for the non-breaking space of police and that has not worked either, which leaves me a bit confused.

    Flash does not support nested lists (as you know).  You can work around this limitation by using css and create your own styles of dash.  CSS have a property marginLeft, that you can use.

  • Question about the configuration of virtual computer file and the working VM location

    I noticed one of my virtual machines had two data warehouses listed under "Items" in the vSphere Client.

    After some research autour, I found the virtual machine files are in the correct data store, but the 'VM-configuration file' and 'Place of work VM' are in another data store.

    Can I combine all in the same database?   I'd rather have the config and the workplace on ma who has a lot of main storage.  For some reason, the configuration file and the location of work were created on a local storage on my host.

    Any suggestions?

    Thank you

    David Moore

    You can use Storage vMotion to migrate only the virtual machine configuration file to the desired location, just start the wizard of vMotion and storage step 'Select the data store', click Advanced, and you will see the option to select a new destination for the configuration file data store.

  • Question about the size of a DVD file made?

    Hi all

    I just finished my first home using Premiere Pro CS4 and Encore CS4 video. My source is a consumer HD camcorder. When I created the PP project, I chose the AVCHD format to keep the best possible quality. Yes Iimported files in PP, apply some transition effects and the title a bit. Then I sent the sequence again via dynamic links. When you create the project in again, I chose the Blu ray. I therefore created a menu and all the navigation, added a subtitle and background music. Initially, I wanted to created a DVD of my video to give the members of the family, so I'll drive created, select output DVD and make the video. Now, here's my problem: the created DVD folder is 7 GB, and my pictures are only 1h45min. I always thought that a single layer 4.7 GB could hold about 2 hours of video? My source in HD, but by selecting the DVD release, shouldn't she converted to SD and fit a 4.7 GB disc? What I am doing wrong?

    Thanks for your help.

    Bruno

    You can change the transcoding settings, by default the transcoding settings are automatic which is for the best possible quality. Right-click on the media in the project Panel, and then select settings for transcoding. Change settings for transcoding DVD NTSC DV high quality 4 MB VBR 2 pass for transcoding. You will be able to check the change in disk space on disk under building Board info after transcoding. If there are still more than you must try with 4 MB or of poor quality.

  • Question about the migration of mass of files and permissions

    Hello

    I'm moving 2TBs of files from one external hard drive to another, but every time that I try to do a file mass transfer from one day to the next it eventually fail due to permissions for some files. I looked at the files on that he objected and I read and write permissions on them, as you would expect.

    What can I do to fix this?

    Try to run repair permissions and ACLs on your record. A repair permissions with disk utility does not have anything in your folder. Boot from your recovery partition now command-keys R in the menu utilities launch Terminal. In the Terminal, type: resetpassword , then press return.  (Note: you won't be reset password)

    Click the icon for the hard drive of your Mac at the top. In the drop down menu below, select your home folder. At the bottom of the window restore Home Directory Permissions and ACLs. Then, click on the Reset button. When the prompt returns to the command line, you can leave out Terminal.

  • Question about the opening of JavaScript (.js) files in Windows Explorer...

    Hello.

    I write web pages with external JavaScript files.

    When I right click on a file in Windows Explorer .js, I get a choice when selecting menu "open with...". » :

    -Microsoft (R) Windows Based Script Host

    -Microsoft Visual Studio

    -Notepad

    Nothing happens if I select the first. What is the first listed selection? Is this something that should have come with Vista?

    What to keep in mind, is that JavaScript is coded in the web pages, for example in HTML format.

    Go to a web page, right click on the white space and choose View Source and you will see the words such as JavaScript and function. If you look at the coding of the function, you should be able to recognize the commands.

    Good luck with the coding.

  • Question about the display of what log file mapped in LogFilter agent

    Hello

    LogFilter agent allows you to have up to 4 different log files (and paths) to match strings in the list.

    Is there a way to make a rule that kicks in when there is a match of logFilter - to have access to what filepath had the match?

    So, for example if I have;

    /path1/server.log

    /path3/server.log

    and if the rule that fires when the logFilter has a match, I would like it to show which of the 2 filepaths contained the game.

    Thank you

    "mark".

    Hi Mark,

    The default LogFilter rule creates an alarm that contains the path to the log file of the execution of the variable of severity level "text".

    This script uses "entry.get("LogName")" to extract the name of the log file, which is displayed in the Message field of alarm and the alarm dialog box as well as the text that triggered the alarm:

    Kind regards

  • I have a simple question about the meta-data.

    Hello. It is a simple question about the meta-data. How can I get the video bitrate of a flv or mp4 (video playing via NetStream file) file

    right now I have this:

    Code
    var netClient:Object = new Object();
    netClient.onMetaData = function(meta:Object)
    {
    for (var in meta props) {}
    trace (props + ":" + meta [props]);
    }
    MovieClip (root) .durations = meta.duration;
    trace (MovieClip (root) .durations);
    };
    NS.client = netClient;

    And my output is:

    audiocodecid: m4as
    aacaot: 2
    Width: 960
    AudioChannels: 2

    As you can see, there is nothing of video bitrate.

    I know that the video bitrate of my videos, but then I have to manually type each number of bitrate into my flash project, and it would be such a fuss when I have a lot of videos. Would be nice if flash can detect the video bitrate.

    It's for my online portfolio.

    Why you divide by 8?  If you want to convert bytes into bits, multiply by 8.

  • A few questions about the use of data and Cliq

    I have the cliq, however I chose to not get 3G (so I bought full fare). So I have a few questions about the phone and the use of 3G / 2 G/Edge:

    1 - is possible to disable completely the 2G / 3 G/Edge? I know you can switch between them, but are anyway just tell the phone to stop using them altogether since I'm not subbed to the service?

    2. when the update takes place, I guess we'll have to reconnect motoblur and etc, but if I don't have 3 G will I have motoblur connection problems after the update? Or he keeps the latest wifi settings so that it would connect to wifi to connect. When I first got my phone it was not a problem b/c I had 3G for the first month.

    I hope that makes sense, thanks!

    To stop all the data, I would like to download an application called APNDroid. He cut them all down. When you log on to blur you have 3G or WIFI doe this without getting a timeout error. During the process of setting up your Blur account, you can press the menu button and set up your wifi to work, this will connect you to Blur and your phone will be connected to the blur. If I were you I would be rethinking to do a data plan since you are really losing out on most of your main features of phones. It's your choice, however.

  • OCP: Question about the critical files on control and collision

    Hello

    I am currently a student at OCP certification exam 1z0-053.

    To do this, I bought the all-in-one fixed Oracle Press (http://www.mcgrawhill.ca/professional/products/9780071629188/)

    During his studies, I would like to test, to prove things and simulate the operation to get more familiar as possible with important concepts.

    The study guide covers the fact that when a critical file is damaged or lost, the proceedings will end. The critical files listed are: all copies of the controlfile, a data file that belongs to the SYSTEM table, a data file which is part of the current tablespace undo.

    As said here's the quote:

    Some of the files are important. Damage to a critical file means that the database instance will end if it is open and cannot be reopened until the damage is repaired.

    [...]

    Practically the moment where that the damage occurs, the instance will end. As always, first reaction of the DBA to an instance crashed should be to attempt a start. It will fail in NOMOUNT mode, with an error message appropriate. The alert log will show what controlfile copy is missing and also - in the section list of parameters to initialize default - controlfile how many copies there are actually is and where they are.

    A self-test at the end of the chapter, it is:

    1. loss of these files will cause a database open failed? (Choose all good answers.)

    A. a controlfile multiplex

    B. A multiplexed log file online

    C. a multiplexed log file archive

    D. an undo tablespace datafile asset

    E. a tablespace temporary assets tempfile

    F. Since the SYSAUX tablespace data file

    G. a file of data space of SYSTEM tables

    H. a data file containing the user's critical data

    [...]

    Answer:

    1. A, D and G. damage to any copy controlfile put an end to the proceedings, as damage to critical tablespaces: SYSTEM and break current tablespace.

    So, under the 11.2.0.3 when I delete or corrupt a control file copy, the instance is not crashing and the database continue to work. Alerts log is only regularly notifynig controlfile missing:

    Fri Aug 30 10:16:02 2013

    Errors in the /u01/app/oracle/diag/rdbms/ocp1/ocp1/trace/ocp1_m000_26767.trc file:

    ORA-00210: could not open the specified control file

    ORA-00202: control file: ' / u01/app/oracle/oradata/ocp1/control03.ctl'

    ORA-27041: could not open the file

    Linux-x86_64 error: 2: no such file or directory

    Additional information: 3

    I'm not really knowledge.

    I have to stick to what is said in the book or the experienced facts?

    Thank you

    Bruno

    The information contained in the Guide of the exam are not correct as written.  The Oracle instance would end on the loss of a single control file.  Oracle documentation on the management of the control files is here:

    Management of control files

    It says: "If a control file is damaged due to a disk failure, the associated instance should be stopped. Once the drive is repaired, damaged control file can be restored using the intact copy of the control of the other disk file and the instance can be restarted. »

    "Stop" means that the instance has become unstable.  Unstable case act differently depending on the situation this way, the book is not (cannot) document the specific behavior that may occur.  While the loss of a control file means that the DBA should be abandoned to the instance, it is a very different thing from the instance to the destination of its own.

    The ultimate source is always the Oracle documentation. I checked the page of errata for this book to McGraw-Hill.  I only see an extra.  Submit this to them and get your name on the page as a contributor.

  • Recently bought a laptop computer; A few questions about the offer Upgrade to Windows 8

    I have a few questions about the Upgrade of Windows 8 offer for new computers.  I recently bought a Toshiba Satellite S855-S5268 of amazon.com, which came with Windows 7 Home Premium.  Toshiba already has a beta version of drivers and utilities for Windows 8 for the S855 on their Web site.

    (1) I bought my laptop in July of this year, and I've not yet registered for 8 Windows Upgrade offer with Microsoft.  Am I still eligible to receive the upgrade, if I sign up soon?
    (2) if I buy the upgrade through this offer, I'll be able to download an ISO file so I can burn the installation media, or do I need to upgrade to Windows 7?
    (3) if I will be able to burn the installation media, I'll be able to erase my hard drive and do a clean install of Windows 8 (which I'd rather do, I have a lot of backups of my data).  I am aware that I would probably need to provide my product key Windows 7 Home Premium 64-bit OEM during the new installation, because it is an upgrade and not a full version; This isn't a big deal, because my Windows 7 Home Premium 64-bit OEM product key is stuck at the bottom of my laptop.
    (4) my current copy of Windows 7 is activated by seeing my BIOS (I have a traditional BIOS, not a UEFI).  If I had to switch to Windows 8 and decide then I'd rather back in Windows 7, for example, a few months later, I'll be able to do that (I burned recovery of Windows 7 with the Toshiba utility disks, which I did), and Windows 7 will continue to activate by seeing my BIOS, even after the installation (and later remove) Windows 8?

    Yes and there are better ways to reinstall Windows 8 without using the installation disc, you can use the reset and refresh.
     
     

    These steps will take you through refreshing your PC:

    · Press the Windows key + C on your keyboard to show the charms (if you use a touch screen: touch the right edge of your screen and drag your finger to the left)

    · Click settings

    · Click change PC settings

    · Click general in the left column

    · Under refresh your PC without affecting your files, click Start

    Then follow the instructions that will be provided on-screen to cool your PC.
