I'm looking to setup a FOSSology instance for the gNewSense GNU+Linux
distro. I was... shocked... shall i say, when i heard the memory
requirement: A fossology db for their upcoming release (version 3.0,
code-named metad) would be about 8GB.
Since it'll be a multi-user installation with different people working
on simultaneously working on different aspects, will FOSSology try to
hold the entire database in memory? If so I need to get a different
machine as the one I was planning to use maxes out at 8GB of RAM and
I'd like something that can be used without swapping.
Plus I read somewhere that FOSSology itself needs ~2GB ram iirc to run
well so I should be adding this on top of the database requirement?

Jason,
I'm not sure where you are getting this information. We have set up a
working system on a laptop with 2gig of memory. We don't hold the db in
memory... plus our db only contains the meta-data about the files
uploaded. The unpacked files are kept on the file system and are
referenced from there.
As far as the next release, we don't have a code name.... and it will be
release 1.3. I'm a developer on the project so I hope I would know
about these things! :-) Can you give me a pointer to where you read this?
I think 8 gig should be fine. I run a system with 12 gig and have no
issues and I beat the hell out of it testing it and uploading lots of
things. We have other systems with 8 gig and they work fine as well.
It really depends on what the total load of all the activities will be.
In general, if you plan to upload and analyze a lot of large files, the
bigger the system the better. It's that good old space vs time.... more
memory, less time....
One other thing you can do it so put your repo on a raid type device so
that the main system disks are not holding the repo. This should allow
for more disk concurrency.
Hope that helps.
