in thread to "use vars" or not to

Thank you for your quick response .

All of my DBI code exists in the module run by the child forked from the listener and so I dont intend to share a connection, but by setting the $dbh globaly in the module run by the child am i causing it to be inherited by the next forked child ?

thanks.

    You seem to be unclear about what fork does, in Perl and on many operating systems. See Fork (operating system) for a more general introduction. If you are on Windows, it's best to avoid fork overall, especially when trying to use DBI.

      Thanks again for the reply and link.

      So to summarize, creating a global (via use vars) $dbh database handle in a module called from a forked child cannot impact another forked child because the child is a copy of the parent prior to the creation of the $dbh. ?

      hopefully thats right ? cheers.
        Right. If the dbh was created before forking, that would be another story.
