Huge mystery file?

I just noticed a huge file in my iTunes Library. It has a song title, but I know it isn't a song. It shows up as being 789:57:13 minutes? long. I have no idea what this is. Any ideas?

Actually when I went looking for this file I found 10 tracks with the same 789:57:13 time. Command +R shows 11 tracks on some of these ranging from 20kb to 4.5mb. On some of the othersit shows 512 tracks. Most of the tracks are mpeg4 audio, but there are also mp3 audio, wave audio, and a few "documents". iTunes total shows 6170 items, 346 days, 22.75GB I have ripped a lot of CD's, but the total used to say about "7 days". iTunes seems to be performing normally. I'm mainly concerned that I'm using up a lot of wasted hard drive space with these large mystery files.

Java Programming: Any Ideas for breaking a huge class file into smaller ?

Hello Java pros,
I have some very huge class files, some with dozens of methods; each method containing an average of a screen-page full of code.
Obviously, such huge class files are difficult to maintain inspite of using an IDE, especially when changes have to be made to a bunch of a category of methods scattered all over the class.
I am wondering if there are ways/best-practices out there to make the core class file smaller/smarter - fr eg.
<a> by retaining the real core definitions within the core class and moving the detailed implementation outside the core class
<b> by breaking down the file into more manageable pieces - something to the effect of using 'include' files that some languages support
etc.
Thanks for your help in advance.

If you have huge class files with dozens of methods, maybe the design of your application is not so sound. You could use all kinds of OO design techniques to design your application so that it is easier to maintain.
Start by learning about design patterns. The most famous book about design patterns is this one: http://www.amazon.com/exec/obidos/ASIN/0201633612/qid=1029971487/sr=2-1/ref=sr_2_1/102-4299125-5141710

Need help -To Restrict Huge temp file, which grows around 3 GB in OBIEE 11g

Hi Team,
I am working on OBIEE 11.1.1.5 version for a client specific BI application. we have an issue concerning massive space consumption in OBIEE 11g installed linux environment whenever trying to run some detail level drill down reports. While investigating, we found that whenever a user runs the drill down report a temp file named nQS_xxxx_x_xxxxxx.TMP is created and keep's growing in size under the below given folder structure,
*<OBIEE_HOME>/instances/instance1/tmp/OracleBIPresentationServicesComponent/coreapplication_obips1/obis_temp/*
The size of this temp file grows huge as much as around 3 GB and gets erased automatically when the drill down report output is displayed in UI. Hence when multiple users simultaneously try to access these sort of drill down reports the environment runs out of space.
Regarding the drill down reports:
* The drill down report has around 55 columns which is configured to display only 25 rows in the screen and allows the user to download the whole data as Excel output.
* The complete rows being fetched in query ranges from 1000 to even above 100k rows. Based on the rows fetched, the temp file size keeps growing. ie., If the rows being fetched from the query is around 4000 a temp file of around 60 MB is created and gets erased when the report output is generated in screen (Similarly, for around 100k rows, the temp file size grows up to 3 GB before it gets deleted automatically).
* The report output has only one table view along side Title & Filters view. (No Pivot table view, is being used to generate this report.)
* The cache settings for BI Server & BI Presentation services cache are not configured or not enabled.
My doubts or Questions:
* Is there any way to control or configure this temp file generation in OBIEE 11g?
* Why the growing temp file automatically gets deleted immediately after the report output generation in screen. Is there any default server specific settings governing this behaviour?
* As per certain OBIEE article reference for OBIEE 10g, I learnt that for large pivot table based reports the temp file generation is quite normal because of huge in-memory calculations involved . However we have used only Table view in output but still creates huge temp files. Is this behaviour normal in OBIEE 11g. If not, Can any one Please suggest of any specific settings to be considered to avoid generating these huge files or atleast generate a compressed temp file.
* Any other work around solution available for generating a report of this type without the generation of temp files in the environment?
Any help/suggestions/pointers or document reference on this regard will be much appreciated. Please advice
Thanks & Regards,
Guhan

Hello Guhan,
The temp files are used to prepare the final result set for OBI presentation server processing, so as long as long you dataset is big the tmp files will be also big and you can only avoid this by reducing your dataset by for example filtering your report.
You can also control the size of your temp files by reducing the usage of the BI server.I mean by this if you are using any functions like for example sorting that can be handled by your database so just push to the DB.
Once the report finished the BI server removes automatically the tmp files because it's not necessary anymore.you can see it as a file that is used for internal calculations once it's done the server gets rid of it.
Hope this helps

Reader 10.1 update fails, creates huge log files

Last night I saw the little icon in the system tray saying an update to Adobe Reader was ready to be installed.
I clicked it to allow the install.
Things seemed to go OK (on my Windows XP Pro system), although very slowly, and it finally got to copying files.
It seemed to still be doing something and was showing that it was copying file icudt40.dll. It still displayed the same thing ten minutes later.
I went to bed, and this morning it still showed that it was copying icutdt40.dll.
There is no "Cancel" button, so this morning I had to stop the install through Task Manager.
Now, in my "Local Settings\TEMP" directory, I have a file called AdobeARM.log that is 2,350,686 KB in size and a file MSI38934.LOG that is 4,194,304 KB in size.
They are so big I can't even look at them to see what's in them. (Too big for Notepad. When I tried to open the smaller log file, AdobeARM.log, with Wordpad it was taking forever and showing only 1% loaded, so after five minutes, I terminated the Wordpad process so I could actually do something useful with my computer.)
You would think the installer would be smart enough to stop at some point when the log files begin to get enormous.
There doesn't seem to be much point to creating log files that are too big to be read.
The update did manage to remove the Adobe Reader X that was working on my machine, so now I can no longer read PDF files.
Maybe I should go back Adobe Reader 9.
Reader X never worked very well.
Sometimes the menu bar showed up, sometimes it didn't.
PDF files at the physics e-print archive always loaded with page 2 displayed first. And if you forgot to disable the look-ahead capability, you could get banned from the e-print archive site altogether.
And I liked the user interface for the search function a lot better in version 9 anyway. Who wants to have to pop up a little box for your search phrase when you want to search? Searching is about the most important and routine activity one does, other than going from page to page and setting the zoom.

Hi Ankit,
Thank you for your e-mail.
Yesterday afternoon I deleted the > 2 GB AdobeARM.log file and the > 4.194 GB
MSI38934.LOG file.
So I can't upload them. I expect I would have had a hard time doing so
anyway.
It would be nice if the install program checked the size of the log files
before writing to them and gave up if the size was, say, three times larger
than some maximum expected size.
The install program must have some section that permits infinite retries or
some other way of getting into an endless loop. So another solution would be
to count the number of retries and terminate after some reasonable number of
attempts.
Something had clearly gone wrong and there was no way to stop it, except by
going into the Task Manager and terminating the process.
If the install program can't terminate when the log files get too big, or if
it can't get out of a loop some other way, there might at least be a "Cancel"
button so the poor user has an obvious way of stopping the process.
As it was, the install program kept on writing to the log files all night
long.
Immediately after deleting the two huge log files, I downloaded and installed
Adobe Reader 10.1 manually.
I was going to turn off Norton 360 during the install and expected there
would be some user input requested between the download and the install, but
there wasn't.
The window showed that the process was going automatically from download to
install.
When I noticed that it was installing, I did temporarily disable Norton 360
while the install continued.
The manual install went OK.
I don't know if temporarily disabling Norton 360 was what made the difference
or not.
I was happy to see that Reader 10.1 had kept my previous preference settings.
By the way, one of the default settings in "Web Browser Options" can be a
problem.
I think it is the "Allow speculative downloading in the background" setting.
When I upgraded from Reader 9 to Reader 10.0.x in April, I ran into a
problem.
I routinely read the physics e-prints at arXiv.org (maintained by the Cornell
University Library) and I got banned from the site because "speculative
downloading in the background" was on.
[One gets an "Access denied" HTTP response after being banned.]
I think the default value for "speculative downloading" should be unchecked
and users should be warned that one can lose the ability to access some sites
by turning it on.
I had to figure out why I was automatically banned from arXiv.org, change my
preference setting in Adobe Reader X, go to another machine and find out who
to contact at arXiv.org [I couldn't find out from my machine, since I was
banned], and then exchange e-mails with the site administrator to regain
access to the physics e-print archive.
The arXiv.org site has followed the standard for robot exclusion since 1994
(http://arxiv.org/help/robots), and I certainly didn't intend to violate the
rule against "rapid-fire requests," so it would be nice if the default
settings for Adobe Reader didn't result in an unintentional violation.

Huge size file processing in PI

Hi Experts,
1. I have seen blogs which explains processing huge files. for file and sftp
SFTP Adapter - Handling Large File
File/FTP Adapter - Large File Transfer (Chunk Mode)
Here also we have constrain that we can not do any mapping. it has to be EOIO Qos.
would it be possible, to process 1 GB size file and do mapping? which hardware factor will decide that sytem is capable of processing large size with mapping?
is it number of CPUs,Applications server(JAVA and ABAP),no of server nodes,java,heap size?
if my system if able to process 10 MB file with mapping there should be something which is determining the capability.
this kind of huge size file processing will fit into some scenarios. for example,Proxy to soap scenario with 1GB size message exchange does not make sense. no idea if there is any web service will handle such huge file.
2. consider pi is able to process 50 MB size message with mapping. in order to increase the performance what are the options we have in PI
i have come across these two point many times during design phase of my project. looking for your suggestion
Thanks.

Hi Ram,
You have not mentioned what sort of Integration it is.You just mentioned as FILE.I presume it is FILE To FILE scenario.In this case in PI 711 i am able to process 100MB(more than 1Million records ) file size with mapping(File is in the delta extract in SAP ECC AL11).In the sender file adapter i have chosen recordset per message and processed the messages in bit and pieces.Please note this is not the actual standard chunk mode.The initial run of the sender adapter will load the 100MB file size into the memory and after that messages will be sent to IE based on recordset per message.If it is more than 100MB PI Java starts bouncing because of memory issues.Later we have redesigned the interface from proxy to file asyn and proxy will send the messages to PI in chunks.In a single run it will sent 5000 messages.
For PI 711 i believe we have the memory limtation of the cluster node.Each cluster node can't be more than 5GB again processing depends on the number of Java app servers and i think this is no more the limitation from PI 730 version and we can use 16GB memory as the cluser node.
this kind of huge size file processing will fit into some scenarios. for example,Proxy to soap scenario with 1GB size message exchange does not make sense. no idea if there is any web service will handle such huge file.
If i understand this i think if it is asyn communication then definitely 1GB data can sent to webservice however messages from Proxy should sent to PI in batches.May be the same idea can work for Sync communication as well however timeouts in receiver channel will be the next issue.Increasing time outs globally is not best practice however if you are on 730 or later version you can increase timeouts specific to your scenario.
To handle 50 MB file size make sure you have the additional java app servers.I don't remember exactly how many app server we have in my case to handle 100 MB file size.
Thanks

Mysterious files being created in pages. Unable to unlock or delete them.

Mysterious files being created in pages. Unable to unlock or delete.

It turns out that you cannot update or delete a Syndication Map that is currently assigned to a Port in the Repository. You must remove the map from the Port in the Repository and then you can change and/or delete them.
1) bring up the MDM Console
2) Unload the repository
3) drill into Admin ~ Port
4) Remove or change the map associated to the port
5) Load the repository
6) Then you go into Syndicator and either Update the Map or Delete it
It had nothing to do with security.
Thank you for your help.

Word docs become huge RTF files in RoboHelp 8.02

Every Word document that I add to the RoboHelp 8 project becomes huge in file size. For example, a 100k Word 2007 document that consists of a couple of pages of text with a couple of small JPEG images (around 50k each) becomes a 15-30 meg RTF file in RoboHelp after importing. The same happens if I created the page/document from within RoboHelp. Is there a setting to keep the RTF files from swelling to such large gigantic sizes?

I found out what the problem was. For some reason, the RTF files swell up when the a jpeg image is added and embedded into the Word document. I created a test document and converted some of the jpeg images to bitmap (BMP) files and used the Image import tool that comes with RoboHelp. The RTF documents stayed tiny even when the same images were added but now as BMPs. The difference is that the RoboHelp image tool creates a link to the bitmap image as opposed to embedding it in the document which is what happened with the jpegs. I read about this in another post that alluded to this in one of the RoboHelp forums.
Thanks!

Mystery files with double extensions

I have been coming across mystery files on my Mac. For example, if I have a file named "word file.doc" I might have a second file named "word file.doc.PkE" or something like that. The file is empty, so far as I can tell. The second extension is meaningless and seems to be random. I can delete the mystery file without harm.
What is creating those files and how do I get it to stop?

That may be an attempt to send you a virus as a Word document. Delete those files. Unless you know the source of the file which comes as an attachment, there is no reason for them to exist. If they are found in your Microsoft Office folder, ignore them as they may be temporary files that office creates for autosave purposes. The only .doc files you should worry about are ones you save to your desktop or home folder or folders you create yourself.

Reading huge xml files in OSB11gR1(11.1.1.6.0)

Hi,
I want to read a huge xml file of size 1GB in OSB(11.1.1.6.0)?
I will be creating a (JCA)file adapter in jdeveloper and importing artifacts to OSB.
Please let me know the maximum file size that could be handled in OSB?
Thanks in advance.
Regards,
Suresh

Depends on what you intend to do after reading the file.
Do you want to parse the file contents and may be do some transformation? Or do you just have to move the file from one place to another for ex. reading from local system and moving to a remote system using FTP?
If you just have to move the file, I would suggest using JCA File/FTP adapter's Move operation.
If you have to parse and process the file contents within OSB, then it may be possible depending on the file type and what logic you need to implement. For ex. for very large CSV files you can use JCA File Adapter batching to read a few records at a time.

Mysterious File in Trash after emptied.

After I empty my trash there is a mysterious file that appears. I try to move it and it disappears, I try to Copy and paste and it asks for my password then disappears. Two separate file names show up at different times. L2QQU6rVMLLrm6 and ntDu9OqOifdnlP .
Also, after I add one item to trash and empty (secure or regular) it shows its emptying 6 items.
hmmm. this is a new issue and Im freaked. am I being hacked?

no, I do not think that. do you have any external drives attached? those files might be from an external and you need to empy trash with that drive attached to get rid of them. also start disk utility and verify your hard drive. if it reports any damage, reboot from the leopard install DVD, start disk utility from the Utilities menu and repair the drive.

Mysterious file in trash containing null chars

in my trash appears a mysterious file. ive made some screenshots of it:
http://home.arcor.de/matthiascando/images/finderError1.png
http://home.arcor.de/matthiascando/images/finderError2.png
it resists any attempts to empty the trash. when i click on it, it disappers only to show up some seconds later again.
i did a rm -rf ~/.Trash - no result. with ls -al ~/.Trash/ it doesnt appear in the terminal.
i tried to create a new account but after a while (a day or so) the file is there again.
has anybody an idea what to do or some experience?

Do you happen to have "show hidden files" enabled? I once had the same problem- a file continually appeared on my desktop and right after deleting it, it would reappear. I then remembered that I had used Onyx to show me hidden files during the installation of some software, and I had never hid them again. That may be one of those hidden files.

Mystery File in Trash and Locked Disks

Hi all,
Have some weirdness going on with my system. First, I have a mystery file appearing in my trash that can not be identified. It appeared about the same time as I started having problems with three of my external drives that I can not access anymore.
The file is named ␀␀␀÷␀␀.÷␀ . It says that it is an alias as type. If you try to get info, it disappears. It will not trash or secure trash. It can not be removed from the Trash folder.
At the same time I have had three external drives start malfunctioning. The files first became unaccessible, could not be copies or delete. The drives would not allow new files to be added. The drive will not unmount and indicates that the drive is engage with an application. Then, the file completely vanish from view. The disk show zero items, but the disk size still indicates the files are still on the drive.
I've use DiskWarrior and DriveGenius to try and repair one of the drives with no success. Even booting from the CD/DVD disk, the drives will not unmount.
I hope this is not some kind of virus or trojan horse.
Let me know if there is something I can do.
Thanks

Take a look at this topic: NUL file in Trash won't go away.
You'll almost certainly find this file is in the Trash on a Windows volume, and you'll need to use Windows to get rid of it.

Mystery file in trash at startup

Hi!
I have this mysterious file in the trash every time I turned the iMac. It has been going on for a while now and I can't get rid of it. Even secure empty trash did not work. When I click on get info, instead of giving me information about the file like all other files do, this one blinks and then disappears and the trash gets emptied. This is the filename ␀␀␀õ␀␀.␀␀ I hope you can read the filename. I even copied the file to pages and made it bigger but this is how it came out when pasting. Under the kind column it says alias. I cannot find this file anywhere in the computer. I have also ran disk utility. Does anyone know what kind of file this is and how to get it rid of it permanently. Thanks.

You might try starting up from your Mac OS X installation disc; at the first Installer screen, go up to the menu bar. Under Utilities, select to run Disk Utility. In the sidebar, select the internal drive; select the drive, not the volume indented under the drive. Go to the +First Aid+ tab and run +Repair Disk+. If there is some minor data corruption causing this problem, +Repair Disk+ may fix it.
If you decide to start using another user account, I would probably use the Shared folder (in the Users folder). Turn ON +fast user switching+ so that I can easily go back and forth between accounts. Then move the files and folders I wanted to move from the old account to the Shared folder. Then switch to the new account and move those files and folders to the equivalent locations in the new account home folder. Do this one user home folder sub-folder at a time.
Note: Dragging files and folders to and from the Shared folder is a move, not a copy. That is, the files will appear at the new location and disappear from the previous location.
If you use Time Machine, you can probably use Migration Assistant while logged in to the new account and migrate from the Time Machine archive. I've never done that myself, but migrating from Time Machine is one of the options.

Mysterious file appearing after login

Hi all,
I recently bought my parents a 2nd hand iMac (Duo Core 2 1.83ghz). After setting up a user account and removing the preference files (which caused a few hiccups), I now have a file that appears when I open the hard drive.
It has no name and is 1.4MB in size. Opening it in TextEdit shows lots and lots of characters (non-English or anything for that matter).
Does anyone have an idea why this file would be appearing and how to fix it? I've never seen anything like this before. Sometimes the trash has a "Recovered Files" folder when I have done nothing.
I've run permissions repairs and verified the disk (which said it didn't need repairing) but I will look at it tomorrow to see if I can find a solution.

Jonathon, kguy is right that you should do a secure erase and then a clean install of everything on a second-hand machine regardless of whether or not you clear up the problem with the mystery file first. I would load only the applications I want on the machine (just in case the current configuration has apps and other things left over from the prior owner) and then you can rest easy.

How do I compress a huge flash file for a web banner?

Hi there,
I am having trouble figuring out how to compress a huge flash file for a small web banner. I have 3 jpeg sequences (lowquality) that are used as background animations and the swf file is now over 900kb. I need a file under 200 or even 100.
thank you for your attention,
Ayka

The only way to reduce the size of the file is to reduce the sizes of the content it has. If you go into your Flash Publish Settings and choose the option to generate a a size report then it will publish a report that will let you know how the weight of the file is distributed and you can focus on eliminating that weight from there.
