[Dspace-general] exceeding the 512 MB maximum file size

[Blanco, Jose]

Michael:

We configured our instance to be able to upload the max integer value
size:

2,147,483,647

But we changed the code to accept a long type for this configuration
parameter, in case we needed a higher upload amount.  Of course the
bigger the file the slower the upload.  You'll have to experiment with
your instance and see if the rate of upload is acceptable.  For us it
was.  I will also point out that you should make sure that the temp
upload dir where the file is to be uploaded to before going in the
assetstore is big enough, or things will hang.  That parameter is
upload.temp.dir and it lives in dspace.cfg.

Hope this helps!

Below is the code I added/changed to be able to accept an upload size
bigger than integer, in case you are interested.

Subject: [Dspace-general] exceeding the 512 MB maximum file size

 
Hello,

Oregon State University is considering changing the DSpace software
settings to allow for submissions of file sizes larger than the default
512 MB maximum file size. We would like to submit several mpeg files
that are up to 2 GB.

Are there any other insitutions that have done so and if so, did you
experience any problems?

Thanks in advance for any assistance,
Michael
