Hi Peter,

Oracle (either DBD or the driver itself) is changing the default signal
handler. This results in the system call always return -1 (in reality it's
the 'wait' call that's returning this value).

Once you establish a connection, try resetting the default signal handler.
E.g.:


My $dbh = DBI->connect( ...
$SIG{ CHLD } = 'DEFAULT';



Regards,
-Aaron

Running perl5.8.3 compiled 32 bit with the Perl libraries, DBD 1.15, DBI
1.41 distributed with Oracle 10.2, I find that, having connected to Oracle
within a perl script any subsequent system() calls return a -1 error status,
even simple commands like true. (First tried building and using
DBD-Oracle-1.19, DBI-1.40 with the same results).


>cat dbtest.pl
use strict;
use Getopt::Std;
use DBI;

# Connect to database
my $db = DBI -> connect("DBI:Oracle:","","",
{AutoCommit => 0,PrintError => 0,RaiseError => 1})
or die "Failed to connect: $DBI::errstr\n"; $db
-> disconnect();

system(true);

print "$?\n";


>/opt/app/oracle/product/10.2/perl/bin/perl5.8.3 dbtest.pl
-1

>/opt/app/oracle/product/10.2/perl/bin/perl5.8.3 -v
