Some files are deleted in the runtime suddenly

Hi all,
I have a strange situation here.
I have a server/client application.
Sometimes I encountered some of files were deleted after I ran the application.
They can be jar files, class files, or property files - no pattern at all -.
I use the Windows Platform (FAT32 file systsem) and JRE1.3.1.
I checked trash can folder after some were gone, but I could not find any from there.
Any clues?
Thank you.

Files only wind up in the trash can if the application that deleted them was coded to send them there...so in general most files never see the trashcan unless you use Explorer to do so.
If I were you I would double check my code carefully.

  • Offline redolog file are delete in Oracle 11

    Hi
    We recently upgrade our Oracle release from Oracle 10.2.0.2 to Oracle Database 11g Release 2.
    I was running the process to table compression with BRSPACE 7.20  using the command:
    brspace -u / -p /oracle/LUK/112_64/dbs/reorgEXCL.tab -f tbreorg -a reorg -o SAPR3 -s PSAPLUK -t allsel -n PSAPLUKCOMP -c ctab u2013SCT
    The process finish ok but I have a problem with Offline redolog, it are generated succesfully but it are delete after a short time, it disappear from the filesystem, I donot understand this behavior, the delete of archive log is not a deliberate configuration.
    If I execute the archive log backup I allways obtain a lot of warnings with redolog file not found:
    Offline redolog file '/oracle/XXX/saparch/XXXarch1_11155_666372933.dbf' not found
    After compression process the Offline redologs files are being delete too.
    I need to know the reason for this behavior, may be a wrong parameter in our database?
    It is a normal situation with Oracle 11?
    What happen with the Database and backup/restore strategy without offline redologs?
    Next week I need to upgrade the oracle release in our productive system, in this system the archive and database backup are very important and I need to solve this issue or fix it.
    Please help me to solve this problem.
    Thanks in advanced,
    OMM

    Hi,
    Offline redolog file '/oracle/XXX/saparch/XXXarch1_11155_666372933.dbf' not found
    Such messages are only seen if some one has deleted/moved the complained offline redo log files form the Archive Log destination.
    Please ensure that if someone has moved/deleted the offline redo log files or not ? It may be done to accommodate space in Archive log destination, as the reorganization/compression activities will generate more archive logs.
    Also try to perform the same activity again and monitor the archive log destination directory. As i think, such "Offline redo log file deletion after Table Compressions activity done by BRSAPCE " behavior is not possible at all. 
    What happen with the Database and backup/restore strategy without offline redologs?
    Offline Redo log files must require in Database media Recovery process. Without it only Point-in-time recovery is possible.

  • Cisco AQM 8.5 not recording : wav files are deleted from client side

    Daer Networkers,
    We do have Cisco AQM 8.5 SR2 ES1 installed with UCCX 8.5
    The issue is that when accessing the Web interface of AQM and try to look for calls, I can't find any one.
    When checking the client side, I can see that the call are being recorded : The FROM and TO files are there. But once the call is terminated, the wav file appear for some seconds and then it dissappears asi fi it's deleted.
    The wav files are not in the server too;
    I don't know what is the issue. Can you please help ?
    Thanks in advance.

    Hi,
    This issue was resolved by doing a repair to the QM Base services, then run postinstall as if it was run for the first once.
    The Proxy Gateway program was missing for some reason. After doing the repair the issue was resovled and calls are uploaded to the server.
    Now I am facing another issue !  : I can hear the client voice only. Agent's voice couln't be heard in the recorded files. As if the agent's voice is not recorded. Can you please advise ?

  • I am unable to see any POP3 or IMAP tab when I set up an account in my iphone 4S. Hence by default all my email accounts become IMAP and the messages are deleted from the server when I delete them from the iphone.

    I am unable to see any POP3 or IMAP tab when I set up an account in my iphone 4S. Hence by default all my email accounts become IMAP and the messages are deleted from the server when I delete them from the iphone.

    ok sorry everyone but i solved it myself but the solution is so nuts i've posted it here to help others who have the same problem.
    to setup a comcast imap account on your iphone:
    go to mail, contacts, etc in settings
    under accts, select add account
    select "other"
    new screen, choose "add mail account"
    now on the new acct screen you must enter your name, email address and password for your GMAIL acct ! (yes i said your gmail acct !, or some other acct with a NON comcast address).
    hit next
    then the acct verifies
    when verified a screen will open with all the acct settings for this acct AND @ the top of the screen are the 2 buttons > imap or POP
    select imap and THEN CHANGE ALL THE ACCOUNT information to the comcast account !
    then hit next and the account will take a couple minutes to verify but it will verify and now you have a comcast imap acct set up on your iphone.  The problem must be that when the iphone sends the initial verify acct info to comcast (if you enter that information first) the comcast server is simply not setup yet to signal the iphone that there is an imap option.

  • Local Files are deleted upon disconnecting from project

    Running Version Cue CS3 3.1.0 with latest Bridge. (PowerMac G5 - OSX 10.4.11)
    Im running the VC server on my local machine. Intention is for only myself to use it for version control.
    I created a project, added my files... the standard local file path is ~/Documents/Version Cue/projectname
    2 issues, perhaps the same issue
    whenever i attempt to disconnect from the project... the local files are deleted...
    so, if i had set a custom path for my projects local files, VC immediately deletes the files, and next time trying to connect, the local file path is reset to the ~/Documents/Version Cue/projectname
    Is this how VC is supposed to function?
    Any help or insight is greatly appreciated!!! Thank you in advance

  • I can't install itunes 11.0.4.4 and so I can't sync with IOS7 can't uninstall old Itunes error message saying some files are missing.  What to do?

    I am trying to install the latest version of Itunes so I can Sync with IOS7 but I keep getting an error message saying it can't dis-install the old version Missing itunes64 files.
    I tried to just un-install the old version but my computer tell me it can't because some files are missing.  I don't know how to find them or how to fixx my problem.  Can anyone help?
    Thanks

    I keep getting an error message saying it can't dis-install the old version Missing itunes64 files.
    (1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    (2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
    (3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
    (4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
    (5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

  • If data files are deleted?

    If data files are deleted, can they be recovered from the control file?

    It depends on what is in the datafiles in the tablespaces, if they actually contain data, if they are the only datafiles for the tablespace, etc.
    Let's assume that they are the only datafiles for the tablespace and segments have allocated and used space in them.
    If the segments are index segments, you can recreate the indexes from the data that currently exists in the table.
    If the segments are table segments, you will need to recreate the data either by hand or extracting it from another source.
    If no segment has allocated space in the datafile, you should be able to offline the datafile. If this works, it is a good idea to migrate the segments to a new tablespace and then drop the tablespace (unless it is SYSTEM) as Oracle does not like offline datafiles and it will become a maintenance hassle.
    If you do not have a backup, do you have a recent export?
    Once you have addressed the immediate issues of reconstructing the data, you need to address the issues of backups (you should at least backup the database periodically even if you don't run in archivelog mode) and security (no one should be dropping live data files).

  • Why All Podcasts Files Are Included In The Music Playlist????

    I am desperate for an answer!!! I have searched online for hours and could not find a solution to this! I have the 5th Generation iPod and everything was fine in the beginning. I recently discovered all my podcast files are listed in the music playlist and this is very annoying because the podcasts are included in the library of songs! When I want to listen to songs, I just wanna listen to songs ... NOT PODCASTS! Why can't the iPod differentiate a podcast file with a music file? They lump them altogether in the music playlist!!!! Under the Podcast category, I found podcasts there also! Which means, the podcasts files are duplicates!!!
    In a summary, this is what's happening:
    1.) Podcast files are grouped in Podcasts playlist in iTunes. Music library does not show them - this is ok, everything's normal here
    2.) Podcast files are listed in Podcast playlist in iPod - this is ok, as it should be
    3.) Podcast files are listed in Music playlist in iPod - WHY????
    I would appreciate some answers to this bizarre problem!!!
    Thanks, guys!!!
    Irene

    well.....to get the podcasts out of the artists menu (if you don't mind them in the compilations menu) you have to go to the podcast's info and press "yes" for compilations. I hope that helps some of you because that isn't really my problem. Because i have a lot of podcasts there is a long list of them in the songs menu and that makes me angry. I wonder if Apple can make an update so that you can choose to have your podcasts in the Artists and Songs menus. If any Apple worker sees this, please do.
    I also have been looking in the internet for answers to this and i have found that the only reason that this is useful if you want to hear a series of podcasts without having to choose a single one every single time.
    I don't know if i read this here, but whoever said that iPods aren't perfect because of this flaw, then they are wrongs. How come they are rightly grouped in iTunes?
    I forgot to mention this. The solution posted doesn't work because:
    1. I erase all the podcast from iTunes and only keep them in my iPod.
    2. I had to erase all my songs from iTunes because i had to format my computer. Yes, it was stupid because i could have backed them up, but i forgot.
    3. When you sync something, you erase everything you have right now. It would take too long to download all the podcast and too much money to buy all the songs.

    How much free space do you actually have? Go to the Apple menu and select About This Mac... More Info... and click on the Storage tab. You should see something like this...
    This will show you how much free space you have and what's taking up all the space on your hard drive. You may need to backup and trash some seldom used files, applications, etc. You have to drag them into the Trash and empty the trash to regain the space. A general rule of thumb is that you should have about 15% of your hard drive storage free.
    Good luck,

    Re: camera connection kit- I uploaded pictures using the sandisk connection, clicked on 10 pics to delete and ALL of my files were deleted from the sandisk! Is there any way to recover these pics?

    Kevin-
    You say you uploaded the pictures to the iPad?  Then they should still be there, and you can copy them to your computer through iTunes.
    There are utility programs for a computer that can recover deleted files from hard drives, and they may work for camera memory cards as well.  I've used DiskWarrior for Macintosh to recover pictures from an SD card before.
