Hello Bob,

Thanks for the detailed information. We will try out "Upload from URL or 
"Upload from server" options and keep you posted if any queries/issues.

Best regards
Kotrappa.

Subject: Re: [FOSSology] What is the maximum file size Fossology Supports?

Hi Kotrappa,

That 700 MB limit is a php limit.  This is for "Upload from File".  You can 
change that in your php.ini file.  See:

http://www.fossology.org/projects/fossology/wiki/SysConfig

Yes, FOSSology can take larger files with "Upload from URL" or "Upload from 
Server".  6 or 10 GB is not a problem.

The amount of time FOSSology takes to scan such a large upload is highly 
dependent on your hardware and what has been previously scanned.  For example, 
I just looked at a recent Android scan we did (3.65 GB) and there were about 
1.2 million files.  However, only 244k files had to be scanned because the 
other million had already been scanned in previous uploads.  Looking at our 
logs I see nomos scanning at from 9 to 42 files/second.  The wide disparity 
will be due to the complexity of the files and the system load at the time.  
You should also know that nomos is single threaded, it only does one file at a 
time.  However, our job scheduler does not have this limitation.  So if you 
break your 10GB upload into two 5 GB uploads and submit them both at the same 
time, they can process in parallel.

For doing large uploads (6-10 GB) a dual core 4GB with 200GB HDD won't work 
very well.  A 10 GB upload, after you unpack all the zip files and tar files 
can easily be over 100GB and you are talking about millions of files that have 
to be cataloged in the database.  The 4GB of RAM is fine for doing scans, but 
once you start doing reports and Postgres starts joining tables with millions 
of records, you are going to be starved for memory.  It will work, but will be 
slow.

My first recommendation is to use a much bigger server.  However, if that is 
not a possibility you could use our agents (ununpack, license, copyright) stand 
alone.  That way they won't write to the database.  Of course, without the 
database, you will not be able to use the fossology GUI for reports.

Hello Bob, Matt,

We know that FOSSology supports maximum file size that can be uploaded and 
scanned is 700 MB.
But if a big chunk of zip file say around 6GB to 10Gb is uploaded to webserver 
( say local apache webserver),
Can FOSSology take the URL of webserver with the big file and scan whole 6GB or 
10GB?
How does FOSSology perform, does it take large amount of time? 1-2 days?
For this big file size scanning, do we need high configuration system? Say 
around 4GB RM, dual core processor, 100-200GB HDD?
