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

Subject: Error always returned from system() after connecting to Oracle
10 .2 on Solaris 64 bit
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
This is perl, v5.8.3 built for sun4-solaris-thread-multi
