  • Where all the redo/archive log volume come from?

    Hi,
    I have a database with a size of around 50G. Thats not very much, but the crazy thing is that this database has a redo log volume per day that is nearly equal the size of the database:

    Every 2 hours redo is backed up to tape.
    There are no significant batches, shaking and shuffling the data around all the time.
    Nearly all changes in this database is happening through user inputs.
    Database is 11gR2 on Redhat 5.6.

    I am afraid there is no easy and direct way to pull the answer from the data dictionary.
    But with some work, you can get to the bottom of this.
    This query shows you how much redo is used by the sessions in your system currently:
    select a.sid , a.value  from v$sesstat a,  v$statname b
    where a.statistic# = b.statistic#
    and b.name = 'redo size'Unfortunately, I am not aware of a AWR view (license required!) that corresponds to v$sesstat, so it would not be easy to look back and see which session generated the redo.
    One way is to troubleshoot the problem online, using a utility such as snapper- http://blog.tanelpoder.com/2010/03/22/oracle-session-snapper-v3-10/ . See which sessions generate most redo and see what SQL they are running at that time.
    The other way is to create your own “repository”. Sample V$SESSION, v$sesstat , v$statname and possibly V$SQL frequently (every few seconds) and record how much redo and what SQLs are running by each session. Once you gather enough data, look which sessions had the biggest “redo size” delta and what SQL were they running at that time.

  • Where are the archived log?

    I've set my server to archive mail logs every 7 days, but I cannot find where they are archived. I do not see anything other than the normal complement of log files in /var/log. Yes it has been more than a week. But where do they go and what are they called?

    It appears that you're assuming rather more around the word "archive" than exists here.
    The archives that you seek are (also) stored in the /var/log directory.
    The log files use the extension .log, and the log archive files use extensions such as .bz2 or .gz, and the associated data compression schemes.
    The following shell command:
    $ sudo find / -name ipfw -print
    will show you all files with the substring ipfw in the filename. Which will show you a few files here and there on your disk that are related to the firewall, including the man pages, and the /var/log directory.
    But no secret archives.
    Run some tests with the archive settings over a week or two, and watch what happens in the /var/log directory.

  • Why can't I delete Mail from my iPhone? it just allows me to Archive, and where do the archives go?

    Why can't I delete Mail from my iPhone? it just allows me to Archive, and where do the archives go?

    You'll have to go to your Settings -> Mail, Contacts, etc -> Email Account -> Advanced -> Deleted Mailbox
    Turn off Archive mode, Turn on Trash
    You can also put the phone in airplane mode to delete them real quick, but that's only a temporary fix.

  • Where is the binary data of this icon stored and retrieved from Application server?

    Hello guys,
    Today I observed one phenomenon and could not explain it per my knowledge.
    I have one url which points to an icon in application server:
    https://<host name>:44301/sap/public/bc/ur/nw5/themes/sap_corbu/common/libs/Icon/SuccessMessage.gif
    I could successfully open it via chrome:
    and after that I could see an entry in ICM server cache. Everything works perfectly.
    Then I tried to check this icon in mime browser in SE80. To my surprise, the folder /sap/public/bc/ur/nw5/themes is empty.
    However, the ICM cache shows that there is a subfolder called "sap_corbu" under "themes" folder. But why I cannot find it in mime browser?
    Then I write a report to retrieve the binary data of icon via CL_HTTP_CLIENT, and clear the ICM buffer via tcode SMICM.
    I expect this time some database table will be queried to load the content of the icon, since now the buffer is not available.
    To my surprise again, in SAT no database table is involved.
    So now I am confused: since I have already cleared the ICM server cache, where does the icon binary data come from when I run the report to access the icon?
    Best regards,
    Jerry

    Hello guys,
    one colleague today told me that there is a zip file "ur_mimes_nw7.zip" in MIME repository /PUBLIC/BC/UR/ur_mines_nw7.zip. I download it locally and unzip it and indeed find many theme folders including sap_corbu folder and its resource files. So I guess there must be some logic done in web application server which will unzip this archive file and put each theme folder to the corresponding folders in application server. I would assume those logic are done outside ABAP stack side, this is the reason I cannot find any hint of them in ABAP backend via tcode SAT even I clear both client and server side cache.
    Best regards,
    Jerry

  • Where is the Format Bar in 5.0?

    Where is the Format Bar in Pages 5.0?  It would also appear that some of the tools such as list styles that were formerly available are missing as well.

    You can archive (compress) Pages 5 after exporting all the files back to Pages '09.
    I suggest rating/reviewing Pages 5 in the App Store, to slowly hammer home the message to an Apple that is largely deaf to its users.
    Apple may be regretting its own reviewing system, as users tell it just how much they hate what it has done.

  • Where is the file that contains my contacts ?

    Hi ...  Where is the file that contains my contacts ?  I want to restore my contacts from a CrashPlan previous backup ?

    It's worth a try anyway, in the worst case = an error from Contacts being unable to read the database, you can simply delete the restored files again.
    In such case, or even as a first step, you may try to use the "Import..." procedure by pointing to a *.abcddb database file from your backup.
    Hint: Before system upgrades presenting me with new versions of Contacts or Calendar, I always backup my databases separately as well per "Export..." in archive format. No trouble so far.

  • Where is the audio track in a dvdproj file?

    I have a number of old iDVD projects stored on hard disc that I need to convert to a useable format.  I've been able to find the MPEG compressed video files by right-clicking on the .dvdproj bundle and opening the Contents/Resources/MPEG.nobackup folder, but the files have no audio track.  Where is the audio track stored?

    Unless you've created an archive iDVD project file the audio is only linked to the project from wherever you kept the files when creating the project.

  • (261936172) Q general Where are the Web Service source files?

    Q <general> Where are the source files for a Web Service created
    with WebLogic Workshop stored? How do I deploy the Web Service
    on a different WebLogic Server? Is there a way to bundle the
    Web Service project files manually to distribute them?
    Is there a way to configure the directory where Workshop stores
    the files?
    ANSWER: (by Adam Fitzgerald, [email protected]) The .jws files are stored
    in the project folder. This can be located on a local system, although by default
    they are in c:\bea\wlserver700b\sample\workshop\applications. The Web Service
    structure is understood by WLS 7.0 so by archiving the appropriate folder you
    can transfer the Web Service in its entirety from one deployment to another.

  • How to correct the corrupted archive log files?

    Friends,
    Our restore method is cloning type.
    today i fired this statement(this is one is usually do for the restore) "recover database until cancel using backup controlfile"
    i have 60 files in the archive folder.
    it executs only 50 files when it comes to 51st file it came out and says could not copy the file.
    is that particular file is corrupted?
    or is there any restriction in copying no of archivelog files? i mean only 60 files like that.....
    suppose if the archive file is corrupted how can i correct it?
    thanks
    sathyguy

    Now, this is the error message....
    ORA-00310: archived log contains sequence 17480; sequence 17481 required
    ORA-00334 archived log; '/archive2/OURDB/archive/ar0000017481.arc'i googled....and find out.....
    ORA-00310 archived log contains sequence string; sequence string required
    Cause: The archived log is out of sequence, probably because it is corrupted or
    the wrong redo log file name was specified during recovery.
    Action: Specify the correct redo log file and then retry the operation.so...from the above error messages.....i think the particular archive file(17481) is corrupted. now can i correct this corrupted archive file.
    According to the above action, it says to specify the correct redo log file. if the file is not corrupted then where should i specify the redo log file's path?
    thanks

  • Where is the location of isight photo for new osx account?

    Hi all - my first post....
    When a new account is created and the (inbuilt) isight camera is used to take a login photo, where on the OS is that photo stored and in what format?
    Sorry if it's basic, but I've searched high and low for ages...
    David
    intel laptop   Mac OS X (10.4.9)  

    Welcome to Apple Discussions, David
    While your question may be basic, the answer is not so simple.
    Yours is actually a question about how OS X works rather than iSight.
    See Niel's Nov, 2006, response to Bernhard VonZastrow1's question in:
    http://discussions.apple.com/click.jspa?searchID=-1&messageID=3532758
    Because this old post has been archived and will be removed from view before this topic is, I quote Niel's response here for the record:
    The login picture can be anywhere on the hard disk; to find its current location, open the NetInfo Manager in the /Applications/Utilities/ folder, and check the picture property for your user account.
    To find this property for a system other than the one currently used to start up the computer, open the Terminal application in the /Applications/Utilities/ folder and run the following command:
    sudo nicl -raw '/Volumes/volumename/private/var/db/netinfo/local.nidb' -read users/username/
    This command will prompt you for your administrator password; nothing will appear in the Terminal window while it is being typed. Look for the picture line in the output to find the path.
    (17705)
    If Niel's response answers your question, please let us know, but wait for Niel to post here so you can credit him with the "Solved" points he deserves.
    If you need more help of info about this topic, you might want to post in Tiger Forums > Administration, Accounts & Login Discussions. Niel and other very smart folks will help you with your OS X questions there.

  • HT2500 Where are the files of past mail kept in the Mail program.

    I want to do an additional backup of my email on Mail.  Where are the files of stored past mails kept?  In the same Mail.app?
    Thanks
    Gil

    Hi Gil,
    On Mail...
    First Quit Mail, then I'd backup these two Mail folders, by right clicking on them in the Finder, then choose Archive/Compress.
    Users/YourUserName/Library/Mail
    Users/YourUserName/Library/Mail Downloads
    (Could be a different folder here if you chose such in Mail Prefs)
    Right click on that Mail folder, choose archive, you'll get everything in the folder, and the folder itself in a file called Mail.zip, move it to a safe place, same for the Mail Downloads folder... only the plist is separate.
    /Users/YourUserName/Library/Preferences/com.apple.mail.plist
