DBD::Oracle and CHLD Signal Handler

[Peter Marksteiner]

I have a strange problem when connecting to an Oracle 10 database:

#!/usr/bin/perl

use strict;
use warnings;
use DBI;

my $rc = system "true";
print "Before:  $rc\n";

my $dbh = DBI->connect("dbi:Oracle:", "scott", "tiger");

$rc = system "true";
print "After:   $rc\n";

$SIG{CHLD} = 'DEFAULT';

$rc = system "true";
print "Default: $rc\n";

   gives the following result:

Before:  0
After:   -1
Default: 0

In other words, connecting to the database meddles with the CHLD signal
handler in such a way that it looks as if all subsequent calls to
system() failed.

This is perl 5.8.6 on an AIX 5.2 system (64bit) with DBI 1.46 and
DBD::Oracle 1.16; the Oracle version is 10.1.0.2.0. I never had this
problem with Oracle Versions 8 and 9.

   Any ideas?
