Need Help??

in reply to Re: to "use vars" or not to
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.	[reply]

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.	[reply]
