Hi Monks

I have written a sample perl program to connect with the database within the time limit of 10 seconds, If is not get connected it should return connection timeout error message.

For this I am using the alarm signal, as below

test.pl 
use DbConn;
use Data::Dumper;

eval{
local $SIG{ALRM} = sub { print "Alarm Captured\n" ; exit ; } ;
my $Sleep_Obj= DbConn->New();
alarm 10 ;
$Sleep_Obj->connection('db_name','hostip','username','password');
alarm 0;
};

if ($@) {
         print "Timed out.\n";
} else {                                print "Connected Successfully\
+n";
}

The above code includes the Dbconn.pm module and connecting with the database with the given ip address, username and password, there may be a chance of database server down, at that time I should be getting the connection timeout, but it never comes out even after reaching the time out. Any possible way to capture the alarm signal on timeout.

DbConn.pm 
package DbConn;
use DBI;
use Data::Dumper;
sub New {
    my ($Class)=shift;
    my $Self = {}; bless($Self, $Class);
 return $Self;
}

sub connection {
shift @_;
     my ($DBname, $Host, $User_Name, $Password)=@_;
     my $dbh = DBI->connect("dbi:Pg:dbname=$DBname;host=$Host","$User_
+Name","$Password",\%attr ) || die $DBI::errstr;
        return $dbh;                 #return the database handle
}
1;
