Maximum file size handled by java

Hi
What is the maximum file size that java can handle i.e if I need to read a disk file using java, is there any limit on the size of the file being read?

The size you can handle is not limited... only by your code :-)
Check MemoryMappedFiles... i handle Gigabyte files with no problem ;-)

Maximum file size that OSB can handle for JMS

Hi,
We have a requirement to process 60MB xml files over JMS in Oracle Service Bus. While prototyping this we are facing heap space errors.
Can somebody let me know what is the maximum file size that we can process? The scenario is as below.
JMS --> OSB --> JMS --> OSB --> JMS
Thanks

if you don't need to access the entire content of the message, you can try using content streaming
(see this OSB - Iterating over large XML files with content streaming discussion)
See also here http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1110513 for best practices.
Otherwise I have noticed myself that OSB is very hungry in memory when loading large messages. I had trouble even with a 5 MB binary file being loaded - this would take 500 MB RAM. in these cases I would rather look for ETL tools such as Oracle Data Integrator or Open Source Pentaho.

The best solution to handle this type of requirement is Using JAVA proxy only,write logic to split the file 10mb only,becaus its not advisable to process more than 10mb files,even SAP say they tested with 1gb.
i had experiece the same in one yeay back,we resolved using JAVA proxy,how to split the file is just take number of lines or try to fine other way...

Maximum File Size on Import?

Hello all, been a ghost reader here but this is my first question (love the forums, btw, super helpful).
I've been editing a feature film on Premiere Pro. We are nearing the end and I received a DPX sequence back from coloring. Upon importing into Premiere (Intermediate Media Timebase set to the appropriate framerate), the importer hangs up. If I click on anything, the program crashes.
Here are my questions:
Is a 2TB DPX sequence a "normal" size for any project? This seems insanely large to me, but this is also my first feature so I could just be ignorant.
If 2TB is normal, is there a maximum file size Premiere can import?If not, should my system be able to handle a 2TB file?
The 2TB file is on an external drive, connected via USB3. Potential to connect via eSATA.
System Specs:
3770k CPU
SSD for OS (256GB)
External Raid 10 - 6TB
32gb RAM
GTX 580 GPU
All help is greatly appreciated!

Thanks for the reply, Jim.
Just to clarify, a file this size (or sequence of files) is common? But generally the only way to handle them is with a RAID 3 setup?
My next question would be, isn't there a lossless format the color people could give me that isn't 2TB? The file I gave them was just over 800GB so it seems really unnecessary for it to be this large.

Maximum file size for importing into Premiere Pro CS6

Hi,
I'm considering recording raw video, no compression at 720p, 30 fps for 20-30 min. This woudl result in a file that is close to 80 Gbytes. I'm wondering what the maximum file size for importing into premiere Pro is and if I need to split this file up into smaller pieces. Any recommendations on how I may deal with uncompressed raw video that is pretty long in length?
Thanks,
Serena

There is bound to be some limit somewhere in the program, but you should be well below that. The biggest issue might be whether your computer is up to the task of handling it. If you will post your computer specs., someone will give you comments on that aspect.
Good luck,
Hunt

Maximum File size in XI

I have 100 MB file to be transferred through XI.
How to check maximum file size limit in XI server.
Is thier any tcode for the same?

Hi ViJaYaNt JhA ,
File size depends on your Java Heap (Java heap depends on your Hardware Config).Basically SAP recommends a size of 5 Mb.
you can try the quicksizer tool on http://service.sap.com/quicksizer.
Also update the HTTPProvider service on the Java server dispatcher to have the parameter MaxRequestContentLength = 800M
The ABAP parameters icm/HTTP/max_request_size_km set to 2097152, icm/server_port_0 TIMEOUT set to 600. rdisp/max_wprun_time = 3600, ztta/max_memreq_MB =2048.
In SXMB_ADM add the parameter TUNING EO_MSG_SIZE_LIMIT = 40M
Best way would be splitting technique.
Splitting the file before it enters XI would considerably reduce the load on XI.
please refer the following links
The specified item was not found.
Refer this blog
Night Mare-Processing huge files in SAP XI
one more suggestion is:
Increase Current Value of the Parameter Nmame : rdisp/max_wprun_time
using Tcode RZ11 and try to process.
I think it is possible to process files Sizes up to 50 Mb.
Refer Note 807000 ,File Adapter: SAP Note 821267.

Maximum file size cfolders

Hi all,
I am searching for a hint concerning the maximum file size which can be obtained by cfolders.
Is there any limit for a file, which can be handled by cfolders 4.0 ?
Our customer wants to deal with files about 50-80 MB.
Thanks a lot
Best regards
Andreas

Hi,
Is there any limit for a file, which can be handled by cfolders 4.0 ?
No Limit for cFolders. it spurely depending upon your had disk size, based on this you can give size for cFolders.

Maximum File Size - 2GB?

Does java have a formal maximum file size for java.io.File?
Somewhere along the way here where I work we started assuming it was 2GB, is that accurate?
Our customer output files are starting to get in the neighborhood of 2GB, and management wants a plan.
Do 64-bit JDKs support larger files?
Does the max file size depend on JDK vendor?
Is there a way to get 32-bit JDKs to open say 5-6GB files?

In all cases, I believe, the file size limits are imposed by the underlying operating system, and the value varies (by system and os version).
Refer to the documentation for your os.

CLM - Maximum File Size for Contract Documents

We did a search but did not find an answer for this. For the CLM system does anybody know SAP's recommendation on the maximum file size that the application can reliably handle for contract documents? We recently increased the maximum file size from 10MB to 50MB to accommodate a larger than allowed file size. Now the business has requested the capacity to add files (pdf files) up to 115MB. Would increasing our file limit to approximately 150MB be within the recommended parameters?

There is no specific recommendation for maximum file sizes as this depends on how your time-out parameters are set, your server resources and network (also tunneling policies). The fact is the higher the filesize the more risk you run in unreliable uploads. Compressing files before uploading is a good practise for larger files.
These are the same issues which you would run into if you for example upload to a sharepoint site or even a copy on a shared drive, it all depends on the same parameters.
Tunneling policies could also affect your performance as it will limit the upload speeds according the priority set on certain network activities and if it limits your bandwidth you run in the risk of time-out so as you see there is no straight answer to your question. I know customers who can without no problem upload 150Mb files and others who already have issues with 50Mb.
Unfortunate, as I do not know your architecture and infrastructure I can only advice to stresstest the conditions of 150 Mb uploades with several user ids and see if you get time-outs or if it degrades the network performance. One of the questions you should ask your business is how frequent are the occurences of 150Mb+ uploads and if it is the appropiate way. It could be that these are very rare and in that case you could ask them to do this outside the busy hours of the network which will provides you less risk in problems.

By default AIX limits maximum file size to 1GB

When writing files larger than 1GB in AIX, I receive a "File too large" error.
This file size limit presents a problem, especially when creating large files,
such as LDIF exports from a Directory Server istance or message store dumps
from a Messaging Server instance.

By default, AIX limits the maximum size of files to 1GB. However, root can
adjust the maximum file size for itself with the following command: 

$ulimit -f arbitrary_large_number
 

The -f modifier
specifies the maximum file size. For example, 

$ulimit -f 4194304

This values for the maximum size of files is set in the
/etc/security/limits
file. The default values in this file are as follows: 

fsize = 2097151 
core = 2097151 
cpu = -1 
data = 262144 
rss = 65536 
stack = 65536 
nofiles = 2000 

To view your local default values, use the following command: 

$ulimit -a

Any user can adjust the maximum file size limit downward. For example, 

$ulimit -f 
2097151 
$ulimit -f 100 
$ulimit -f 
100 
$cp /unix /tmp/MyBigFile #(copy a big file to another location with enough space) 
File too large 
$ls -al /tmp/MyBigFile 
-rwxr--r-- 1 UserID GroupID 51200 Jul 25 08:41 MyBigFile
$

However, only root can adjust the ulimit
file size limits upward. Such changes
will take effect only after the user logs in again.

Additionally, it is possible to set specific user limits with the
chuser command. For
information on chuser,
click the following URL: 

http://www.rs6000.ibm.com/doc_link/en_US/a_doc_lib/cmds/aixcmds1/chuser.htm#A067913d9

For more information on the ulimit
command, check the following URL: 

http://www.rs6000.ibm.com/doc_link/en_US/a_doc_lib/cmds/aixcmds5/ulimit.htm
Note: 
The shell in use may affect the actual limits imposed by ulimit
. In particular,
/usr/csh may not
properly adjust the limit from the default value. Also,
bash (Bourne Again shell)
may treat file sizes in blocks as though they were file sizes in kilobytes(KB).

The size you can handle is not limited... only by your code :-)

What is the maximum File Size we can send

Hi Experts,
I have done simple scenario file to file without IR.
I have one doubt here, what is maximum file size (Text and XML)we can transfer from source to target ftps.
text file = file size?
xml file = file size?
Thanks for inputs.
Bhaskar

There is no limit to the message size (file size) that can be transfered.....the only thing required is that your server should have the necessary configuration (hardware) to handle a file of a particlar size.
this question is actually asked a couple of times and in there people have even mentioned the transfer of files in 1GB ... so it all depends on your Hardware.

Abhishek.

Is there a way around the Maximum File size of 2.0 GB Exceeded message???

I tried to bounce a two hour mix set for the first time today, and I received this message
---->Maximum File size of 2.0 GB Exceeded
I've tied fiddling with the tempo (read somewhere that this might help), but to no avail. I originally wanted to bounce a file down to 192 kbps. I mean is there no way to record anything over an hour and a half into Logic?
Please advise! Thanks!

Yes. Use the .caf file format. No file size restrictions.
LP8 Use4r Manual. p. 359:
*Maximum Recording Size*
+The AIFF and SDII file formats can not handle audio file recordings larger than 2 GB:+
• For 16 bit, 44.1 kHz stereo files, this equals a recording time of about 3 hours and 15+
minutes.
• For 24 bit, 96 kHz, 5.1 surround files, this equals a recording time of about 20 minutes.+
+The WAV file format can not handle audio file recordings larger than 4 GB:+

What is an idea of maximum file size for a film in Captivate?

Hi there,
I'm creating an elearning course in Captivate 7, and it is being published as HTML5. This means the films I've imported are being converted to MP4s, and they are around 10-20mb in size once they've converted. They seem very slow to load on some computers - do you think the file size is too big? Or could it be another issue? Does anyone have a recommendation for maximum file size for films? They are 572 x 322px and around 1-2 mins in length.
Thanks in advance

Probably better guidelines that dictates 'size' of a vi are:
typically no more than 1 video screen in size
is it legible
and is it's function and operation clear.
I have seen examples of '1 vi does it all' that were many screens wide and tall, totally a flustercuck, and nearly 1 MB in size.
Globals and local variables (except for LV2 style) are typcially shunned for they can create a host of problems (race conditions, indeterminant data).
Use connector pane to wire controls and indicators to. Then use wires between vi's to transfer data. I tend to use clusters to hold shared data.

Maximum file-size for HR EIC emails

Hi folks
We currently use EIC in ERP, and have an issue with sending large emails/attachments as the maximum file-size appears to be only 2MB. This is set in the IMG activity Employee Interaction Center (EIC) -> Interaction Center Web-Client -> Communication Channels ->E-Mail -> Define E-Mail Profiles, the attachment maximum size is set to a maximum of 2,147,483 bytes.
I have tried searching for anyone else having a similar problem, but haven't found anything. I would imagine many customers would have EIC users in a Shared Services environment sending attachments over 2 meg; so before we log a call with SAP, has anyone else had this issue and how did you resolve it?
Thanks very much.
James

The maximum value is 2,147,483 bytes, which is what the config is set to. This seems pretty low, especially in this day and age.
