I don't think you will be limited by Sqlite's database size capabilities - see my reply to marto above.

FYI - current versions include FTS (Full text search) capabilities.

Sqlite and perl run on every platform I have heard of.

I'm not familiar with Solr - it certainly looks interesting - and may map better to your problem domain. However, I got the impression you wanted a stand-alone (not web-server based) solution. Sqlite may be better for that option. Yes - you will need to install each stand-alone instance, but installation is trivial - just copy the file in. Also - it is possible for multiple sqlite clients to access a single shared sqlite database file.

    [Corion]: Maybe doing a double-fork (daemonizing) can make go that information away, but maybe not
    [Corion]: But I think my knowledge of unix/Linux datastructures is several decades out of date, so I don't really know what information it keeps on processes
    [oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
    [tye]: I just daemonized and getlogin() still knew who I had been.
    [tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
    [Corion]: tye: That's really interesting, but maybe it is because getlogin() returns the name, or the uid, so if that user has been replaced by another user with the same uid in the meantime, that's no problem to the system...
    [davido]: or on ubuntu /var/run/utmp
    [Corion]: Otherwise, I would imagine that a user with a process still alive would lock that information in memory.
    [davido]: so last -f /var/run/utmp on ubuntu provides similar (though more verbose) info
