in thread File rights?

Thanks, I went and checked out these links. My problem is I
I don't need to lock the files, they are read only when searched.

What I need is for mutiple users to be able to search the db files at the same time.

    Locking isn't just for writes. If you read the links, you'll find mention of creating multiple copies for readers. Also, the BerkelyDB module is mentioned, which supports the single writer/multiple reader scenario you are describing (without making copies).

    Not to be terse, but go back and read it again :)

      Oooppps, reckon you mean this passage

      Tie::DB_Lock A DB_File wrapper which creates copies of the database file for read access, so that you have a kind of a multiversioning concurrent read system. However, updates are still serial. Use for databases where reads may be lengthy and consistency problems may occur.

      Now I have to figure out how to use this. I'm still pretty much a rookie at this. Sigh. It never ends.
