Hi, monks!

I've got a server which listen()s on a certain port and then fork()s off a new process for every accept()ed connection.
Each child process then reads X number of bytes from the socket, checks data for validity and then writes everything to the database (Oracle).

In the current implementation, each child process does its own $dbh = DBI->connect($source, $uname, $auth, \%attr); thing and I have a feeling that this slows things down dramatically...

So, my question is:

Is there a way to share the same database connection among multiple processes ?

For instance, can I do the following?

... my $dbh = DBI->connect($source, $uname, $auth, \%attr); while(1){ ########################## # accept() code goes here ########################## my $cid = fork(); if (defined $cid){ if ($cid == 0){ my $statement = q!a SQL statement goes here!; my $sth = $dbh->prepare($statement); $rv = $sth->execute; ... etc ... exit 0; } }else{ # handle the error } ...
What will happen in case when multiple processes try to use their copies of $dbh at the same time?

Any input is greately appreciated.
Thanks in advance!
