File adapter with QoS=EOIO Is there any filesize limitation?

Dear Experts,
I'm using a File/FTP Sender adapter with Quality of Service = EOIO (Exactly Once In Order) to keep the polled order of the files.
In the processing parameters I defined a queue name and everything is working well for small (~1 MByte) files.
But if I want to transfer bigger (~25 MByte) files, the whole Java stack collapses and the system has to be restarted.
Is there any size limitation for this own defined queues?
Have you any experience with this kind of processing?
Any comments / experiences are welcome!
Best regards,
Andras

Hello,
there are several files to poll, we have to keep the alphabetical order of them.
It seems, that we have this issue only with EOIO. (EO works good)
After the system has restarted, the first file from the queue was processed, but with a n error message "Could not delete file 'filename.dat' after processing: java.lang.NullPointerException"
(the delete option is on after the transfer)
Is there any possibility to check the mentioned "QuicSized" settings?
I just wanted to know, if there is an "unofficial" size limit of these queues.
Thank you!

Oracle .dbf filesize limitation

What is the file size limitation for the different .dbf files?
When using the trying to create our database with Oracle 8.1.7, we get the following error:
ORA-01119: error in creating database file /oradata/users01.dbf
ORA-27044: unable to write the header block of file
The partition where I am trying to install the files has a size of 30GB. I am trying to create the file with a size of 5GB and 15GB. Creating the files with a size of 1GB works fine, anything bigger that 1GB doesn't work.
Any help would be greatly appreciated.
Regards

But also, why use ODBC? It is not that much more complex to use the OCI (Oracle Call Interface) directly. The basic call interface of both are very similar. But OCI packs a much more powerful punch.
OCI is also directly supported by abstract layers in a number of languages. ADOdb for PHP and Python. DBI for Perl. Etc. Thus no need for ODBC.

Upload FileSize Limit

Hello all
I plan to use an applet to send a file to a servlet for file uploading. here is the catch, when I use <input type = file> I was limited to 100 megabaytes. I am trying to transfer upto 800 megabytes - 1gigabyte of data (specifically video). before I start, are there any filesize limits ? Also what type of connection would you recommend for video files this big
Thanks

Feedburner file size limitation issue

Hey guys,
I'm Alex woking at 'micimpact', South Korea.
We launched our video podcast in April and now have uploaded more than 80 episodes in the channel.
We are using Blip.tv to upload the video files and burned our feed in Feedburner.
But the problem is, as the title is implying, Feedburner won't allow me to upload new episodes due to the 'feed filesize limitation' issue.
So I have 2 questions;
1) is there a way fo me to reduce the filesize?
if not,
2) is there a way for me to continue uploading episodes WITHOUT having to delete older episodes
My understading of the issue goes this far.
I will be more than happy to recieve advises from people who experienced similiar problems.
*the url of the Feedburner feed is
http://feeds.feedburner.com/micimpact-tv
(there should be 6 more episodes showing which are already uploaded in Blip.tv)
*the url for the podcast:
http://itunes.apple.com/kr/podcast/cheongchungominsangdamso/id516903991?mt=2
Cheers!
Alex

The blip.tv link is to the web page, not the feed, and I can't see a link to the feed on it. However, the Feedburner feed will contain everything that's in the blip.tv feed, plus an number of tags which FB adds for the benefit of other rss readers.
It's the first time I've come across a size limitation on Feedburner. The problem is that the blip.tv feed is, to be brutally honest, a mess - it's got masses of 'blip:' tags which are no use to iTunes but expand the size of the feed considerably.
Presumably there's no way of getting FB to accept more than 512k in the feed (though you could approach their support, if any, for advice), so unless you want to go through the hassle of finding another way of making your feed (and I have to say that blip.tv has caused problems in the past and it's not a method I would recommend) your only option is to start removing older episodes. 81 is rather a lot anyway - new subscribers are not really very likely to go to the bother of downloading 80 older episodes, so dropping the oldest episodes is unlikely to have much practical effect.

Error 2048 under Windows 7 64bit when opening DNxHD .mov

Hi people,
i'm experiencing a weird problem while trying to open a DNxHD encoded .mov file with quicktimeplayer under windows 7 64 bit.
getting the error 2048: "Couldn't open the file because it's not a file that QuickTime understands."
filesize is 5,6 GB and im running Quicktime 7.7.5, the file was encoded using avid media composer.
Other (smaller, around 2GB) files from the same source and using the same codec will play back fine!
This file is running fine on my macbook (10.8.5), but will fail to play under windows 7 bootcamp or on my PC.
I've read about filesize-limits around 4 GB, is there some truth to that?
thanks for your help
EDIT: i need to be able to play back the file with quicktime-components (not vlc or something like that) because im working with protools, which is using quicktime for video-playback.

Thanks for your reply nyc.
But the code i copied is in fact an extract of the USBDescriptors.c present in this directory.
If I try to execute this example, the result is the same.

Best practice for photo format: RAW+PSD+JPEG?

What is the best practice in maintaining format of files while editing?
I shoot in RAW and import into PS CS5. After editing, it allows me to save as various formats, including PSD and JPEG. PS says that if you want to re-edit the file, you should save as PSD as all the layers are maintained as-is. Hence I'd prefer to save as .PSD. However, in most cases, the end objective is to share the image with others and JPEG is the most suitable format. Does this mean, that for each image, its important to save it in 3 formats viz RAW, PSD and JPEG? Wont this increase the total space occupied tremendously? Is this how most professionals do it? Pls advice.

Thanks everyone for this continued discussion in my absence over two weeks. Going through it i realize its helpful stuff. During this period, i downloaded Aperture trial and have learnt it (there's actually not much learning, its so incredibly intuitive and simple, but incredibly powerful. Since I used iphoto in the past, it just makes it easier.
I have also started editing my pics to put them up on my photo site. And over past 10 days, here is the workflow I have developed.
-Download RAW files onto my laptop using Canon s/w into a folder where i categorize and maintain all my images
-Import them into Aperture, but letting the photos reside in the folder structure i defined (rather than have Aperture use its own structure)
-Complete editing of all required images in Aperture (and this takes care of 80-90% of my pics)
     -From within Aperture open in PS CS5 those images that require editing that cannot be done in Aperture
     -Edit in CS5 and do 'Save', this brings them back to Aperture
     -Now I have two versions of these images in Aperture - the original RAW and the new .PSD
-Select the images that I need to put up on my site and export them to a new folder from where i upload them
I would be keen to know if someone else follows a more efficient or robust workflow than this, would be happy to incorporate it.
There are still a couple questions I have:
1 - Related to PS CS5: Why do files opened in CS5 jump up in terms of their file size. Any RAW or JPEG file originally btn 2-10 MB shows up as minimum 27 MB in CS. The moment you do some edits and/or add layers, it reaches 50-150MB. This is ridiculous. I am sure I am doing something wrong. Or is this how CS5 works with everyone.
2 - After editing a file in CS by launching it from Aperture, I now end up with two versions in Aperture, the original file and the new .PSD file (which is usually 100MB+). I tried exporting the .PSD file to a folder to upload it on my site, and wasnt sure what format and size it would end up with. I got it as a JPEG file within reasonable filesize limits. Is this how Aperture works? Does Aperture allow you options of which format you want to save the file in?

Making Lumia ringtones

To start off, the 40 second / 1 MB limit is ridiculous. Whoever decided on it, should be fired. How can Lumia play songs that are longer than that but enforces the limitation on ringtones?
Anyway, how can I make ringtones. I've read everything, and it seems to boil down to
(1) learn to use a professional sound editor, edit your music, produce the song in MP3 or WAV format of the appropriate sound quality, and after all this...)
2) switch the Genre to "ringtone". Simple!
I'm having a bit of problems with step 1 here. Could somebody please provide a simple walkthrough here with an application?
Given the ridiculous ringtone length and filesize limitations, why does Nokia not provide a ringtone maker? You would simply choose the sound file and say "Save copy as a ringtone", at which point the file would be cut to 40 seconds maximum and saved in a compatible format of the maximum allowed size, and the Genre would be automatically set to "Ringtone". Would this make too much sense?
Maybe Nokia just wants us all to revert back to Nokia Tune for our ringtones after all this personalised nonsense. Needless to say, given this one limitation - which I would never have thought of before buying this Lumia 900 - and the fact that music is a big part of my personality, the Lumia 900 is a useless piece of junk that will embarrass me every time it starts playing one of its standard ringtones.

Hi roope70,
Thanks for your feedback.
While I can see how you would ask why these limitations in general it seems safe to assume a ringtone will sound for less than 40 seconds before you pick up, so having longer ringtones would not have any practical use and the track(s) would only take up additional space.
Creating a ringtone is very easy, you can use the free app 'Ringtone Factory' to select and cut the section you want to use. Besides this app you will find many similar apps in Marketplace.
Hope this helps,
Kosh

Threads write and move files

Hi,
I'm trying to run the codes below with 200 threads using JMeter simulation (TCP connection). Here's my logic:
- clients connect to a server, server accepts and creates new thread
- the thread suppose to write the data into a file, but the file must be less than some size, in the case below is 200 bytes
- when the 200 bytes size limit is reached, the thread needs to move that file into another folder and then create a new file for the data to be written
- the writing data part is fine, but the moving data is not (many files aren't being moved)
- i should also mention, i declared the fname to be static variable (to be shared by threads)
So would anyone please help me like to give me advices if my codes below will work with the scenario above or if i need to approach the problem differently?
Thanks
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
while((data = in.readLine()) != null) {

    data = (data.replaceAll("[^0-9A-Za-z,.\\-#: ]", "")).trim();
    String [] result = data.split(",");
    if (result.length == 19) {
        if ((fname.trim()).equals("")) {
            DateFormat dateFormat = new SimpleDateFormat("yyMMddHHmmssSSSS");
            Date date = new Date();
            fname = "log_"+dateFormat.format(date)+"_.txt";
        else {
            File outFile = new File("temp\\"+fname);
            //System.out.println("outFile.length(): " + outFile.length());
            // check if file is > filesize
            if (outFile.length() > 200) {
                fdata = fname;
                DateFormat dateFormat = new SimpleDateFormat("yyMMddHHmmssSSSS");
                Date date = new Date();
                fname = "log_"+dateFormat.format(date)+"_.txt";
        synchronized (fname) {
            write(data);
            move(fdata);

i think 'SSSS' is fine, because it extends the 'SSS' which is a date placeholder. The files that I try to write to are logs file. I actually having trouble to write it, that's why i need to include the 'SSSS'.If you want each thread to have its own file, 'SSSS' may not be good enough. Java is extremely fast at creating objects, and you could easily have 10 threads competing to write to the same temp file. As I said above, if you don't want this, add the Thread ID to your filename. Remember, just because Java time fields allow milliseconds doesn't mean they provide that accuracy. The clock on my home computer actually ticks over about every 15ms.
That's indeed one of the problem that I'm facing right now. I thought synchronization will take care of this problem.Only if all threads share the same object. As far as I can see, you are synchronizing on a filename created within the thread itself (I'm assuming your original fragment is part of the run() method) so the only synchronization you'd get would be from the I/O itself.
Yes, I am aware of this fact too, once the code is decent, it'll be moved to unix systemEven so, make sure you clean up your files after you're done with them. It seems that this setup has the potential to create thousands of files, and even a Unix filesystem has its limits.
My problem is that: there's a tcp server that listens to clients and receive that from it. The data needs to be inserted to the database. But with the volume of clients that connect to the server at the same time, I was thinking it's better to write it to temp file first (with filesize limitation), then to destination folder. There will be another process whose jobs is to parsing the files and move it into database. OK, so I presume each Thread is listening to output from a specific client, with a time limit for waiting (again, this isn't my forte, but I notice you have a 5 second timeout on the socket).
A few other problems I see with your code:
1. You've given each thread a limit of 200 bytes; on a decent size disk, the blocksize will be 4K (or even 8), which means that even if you write a file of 200 bytes, it will take up 4K on the disk.
2. You create a new File and FileWriter object every time you write a chunk of data, which creates a lot of work for the garbage collector. Create them only when you need to open a new file and simply use them until you want to close it and move it. To facilitate this, pass Files between your methods, not names. In fact, for the write method, you can pass the FileWriter.
3. The regex you use to filter your data includes "\\-#" which is not a valid range. It may well work, but it's always better to put '-' at the end of a metacharacter if it's not part of a range. Also, is a space (' ') the only valid space character you can receive? If, for example, the data could include tabs, you might be better off using '\s' (in the string you'll need "\\s").
A few other suggestions (I'm assuming that all data read from a particular socket before a timeout comes from a single client):
1. Make your size limit much bigger and a multiple of 1000 bytes (this should allow for any extra characters that may be added by the operating system). I'd suggest 4,000.
2. Split the process of reading and writing into two separate threads. Disk I/O is, almost certainly, by far the slowest part of this process and therefore the most likely to block.
One possibility for (2) is to append your validated data lines to a StringBuffer or StringBuilder and, when your size limit has been reached, copy the contents, pass the copy to a new writer thread, clear your buffer, and continue the process.
The advantage of this is that your reader thread will only ever be blocked on input, and each writer thread will have a chunk of data that it knows it can put in one file (and probably directly into the 'inbox' directory).
It still might not be a bad idea to have the "reader" thread create the filenames (don't forget to include the thread ID) and have it keep a "chunk" counter. The filename then becomes date/time plus reader-thread-ID plus chunk#, which ensures they will always be in sequence for your parser.
Your code might then be something like:
public class ReaderThread implements Runnable {
   private static final CHUNK_SIZE = 1000;
   private static final DateFormat dateFormat =
           new SimpleDateFormat("yyMMddHHmmssSSSS");
   private final String timeStamp =
           dateFormat.format(new Date());
   // Give your buffer enough extra capacity to complete a line.
   // (this'll just make it run a bit quicker)
   private Stringbuilder data_chunk = new StringBuilder(CHUNK_SIZE + 100);
   private int chunk_counter = 0;
   public void run() {
      // validate your lines as before, and inside your
      // 'if (result.length == 19)' block...
         data_chunk.append(data);
         if (data_chunk.length() >= CHUNK_SIZE)
            handoff(data_chunk);
      // remove all your filename stuff and the synchronized block
   // this is the method that hands off your data "chunk" to the writer thread
   private void handoff(StringBuilder chunk) {
      StringBuilder chunkCopy = new StringBuilder(chunk);
      String outfile = String.format("%s.%d.%7d",
                  timeStamp, this.getId(), ++chunk_count);
      WriterThread w = new WriterThread(chunkCopy, outfile);
      new Thread(w).start();
      chunk.delete(0, chunk.length());
}This is just a possibility though, and there may be better ways to do it (such as communicating directly with your parser class via a Pipe).
I'll leave it to you to write the WriterThread if you do decide to try it this way.

Difference between Oracle 10g 64 bit /Oracle 10g 32 Bit Windows

Hi all
We are using 10g Oracle 32 Bit windows as well as Oracle 10g 64 Windows at some installations.
Now we tested these two systems in our office for Testing purpose on two similar machines i.e
Intel i3 with 4 GB RAM. Database size approx 4GB
We had the feeling that :-
a) Oracle datafile Filesize limitation may be there in 32 Bit system but we saw that physically around 3.5 GB datafile size
is created in 32 Bit windows also
b) Data Fetching Speed -.We thought that data fetching speed would be higher in 64 Bit machine. But we proved to
be wrong. Our sample data had approx 7 Millions records (based on Client Live data for 3 years) total in around 20 transaction tables. Further there were other additional 100-150 tables but very smaller ones just master tables
We used the same client end machine and same Front end and same queries on both servers. To our surpriise - We got the almost similar results in terms of data fetching time in both the 32 Bit as well as 64 Bit windows with similar Oracle 10g 32 bit and Oracle 64 Bit respectively
Further we find that Anti Virus Programme which may be any say Symatentic or other - troubles much more in Windows 64 Bit environment as compared to Windows 32 Bit environment from settings point of view.
Kindly advise as to
a) Whether our above observations are correct
b) Now under what situations should we use Oracle 10g 64 Windows as compared to Oracle 10g 32 Bit windows

Suresh Bansal

Resolution limit exporting to TIFF or JPG

Hi,
I can't export 4500x2500mm image with 300 or even 150 dpi. Need to do it with only 96 dpi.
I'm using Acrobat X Pro.
What is the limit and why is there limit?

Photoshop CS and later can work with documents up to 300,000 pixels in each dimension, but it's limited by RAM and when saving a document you have filesize limits due to the bit depth of the headers:
PSD = 2GB
PSB = 4GB
Tiff = 4GB
A Tiff file can in theory contain an image with a 4 billion pixel canvas dimension, but in practice it would exceed the filesize.

Fsbtodb macro in ufs_fs.h does not return correct disk address

I'm using fsbtodb to translate the file inode block address to file system block address.
What I've observed is fsbtodb returns corretct disk address for all the files if file system size < 1 TB.
But, if ufs file system size is greater than 1 TB then for some files, the macro fsbtodb does not return correct value, it returns -ve value
Is this a known issue and is this been resolved in new versions
Thanks in advance,
dhd

returns corretct disk address for all the files if file system size < 1 TB.and
if ufs file system size is greater than 1 TB then for some files, the macro fsbtodb does not return correct value, it returns -ve valueI seem to (very) vaguely recall that you shouldn't be surprised at this example of a functional filesize limitation.
Solaris 9 was first shipped in May 2002 and though it was the first release of that OS to have extended file attributes I do not think the developers had intended the OS to use raw filesystems larger than 1TB natively.
That operating environment is just too old to do exactly as you hope.
Perhaps others can describe this at greater length.

Transferring video from a HD camcardor that uses a SD card.

I need help, I have an iMac and I would like to transfer my video from my new HD SD card video camcorder to imovie. When I try the video is broken into photo clips. How can I transfer all of the video footage from my SD card in my imac's imovie?

Hi Mary - no worries about responses.
I am no expert about handling the AVCHD format, nor using OS10.7. Under OS10.6 I have not had a problem when I copy the whole PRIVATE folder containing all the subfolders. Because the AVCHD format has a specific encoding system and folder structure, the programs used to read and/or edit AVCHD material need to have all the folders to have enough data to put the whole movie together. I think Panasonic has a program used specifically to handle AVCHD movies and convert them into more familiar formats. Final Cut has similar capabilities (at least FCP did). I believe the current OS10.7 version of Quicktime Player can play AVCHD and likely needs the whole folder system, too.
The short answer is that you can do an ordinary copying routine, but copy the whole Private folder and everything inside it, to get the whole movie and all the data that the import/conversion programs need to assemble the whole movie. I would copy that into a new folder with the name you want for the movie.
There are actually movie clips deep inside the inner folders, but they are in a special format and a long movie is split up into (I think) 2GB segments to conform to a filesize limitation.
You may need to ask an AVCHD expert the best workflow, once you determine how you intend to handle the movies - for example, if you intend to import into an editing program, or perhaps you just want to convert them into a more convenient, ordinary format like .mov.

Need some help-getting an error while installing

Hi all..
I am having a problem while installing Java applications via GPRS. The application's working fine when i download it from a remote site and install it on the emulator. But when i try downloading and installing it via GPRS on to a java enabled phone it gives me en error "Invalid Application". And on another phone tells me "Downloaded jar file are invalid"
Please give me your suggestions on how to solve this error.

Sound like a corrupted jad-file. Check if MIDP and CLDC version are set correctly and also take care that the jar-file does not exceed the filesize limitation of your phone.

Files that make up a tablespace

Hi,
I understand that a tablespace is the lowest level logical entity for storing data and that it can be made up of several physical files.
What I am unclear about is how Oracle distributes the data in the physical files (i.e. say I have TB01 (3GB) made up of 3 files TB01_01.ORA (1GB), TB01_02.ORA (1GB) and TB01_03.ORA (1GB). The tablespace is initially empty. If I create a table for one of the schemas using tablespace TB01 and insert enough rows to occupy 1/3 of the tablespace then how should I expect to see the data distribution in the physical files ? ).
I guess my question could be read as :
Is it necessary or even recommended for a tablespace to be made up of several (smaller) physical files if I have enough physical disk space for one large physical file ?
Thanks,
Gabriel

Hi,
The reason for having several datafiles on the server for a tablespace is the OS filesize limitation (typically like 2G on UNIX). Another reason is to be covenient
for portable tablespaces, and so on.
However, if you don't have OS limit (like Windows) then having one big tablespace is enough.
If you want to see the distributiion of datafiles run the following query first and then create your table and re-run the query again to see the file distribution.
select f.tablespace_name, d.file_name, sum(f.bytes) free_space_on_tbl
from dba_free_space f,
dba_data_files d
where d.FILE_ID = f.file_id
group by f.tablespace_name, d.file_name;
