Hi I could not understant why I got the following error message :
This Perl has neither ithreads nor 5005threads at
/usr/local/lib/perl5/5.8.6/Thread.pm line 335
BEGIN failed--compilation aborted at
/usr/local/lib/perl5/5.8.6/Thread.pm line 335.
Compilation failed in require at close_session.pl line 4.
with the following piece of code :
#!/usr/bin/perl -w
use strict;
use DBI;
use Thread;
my $db_user = 'dbmaster';
my $db_password = 'xxx';
my $db_host = '192.168.123.90';
my $dbh = connectToServer ($db_host,$db_user, $db_password);
my @dbs = getDatabases ();
sub connectToServer {
warn "Connection to server ..\n";
my $dbname = shift || '';
my $dbusername = shift || '';
my $dbpassword = shift || '';
$dbh = DBI->connect($db_host, $dbusername, $dbpassword);
if (!$dbh) {
warn("DBI: !! Unable to connect to dbname:$dbusername...");
}
else {
print "connected";
}
kill 9, $$ unless $dbh;
return \$dbh;
}
sub getDatabases {
warn "Get databases ...";
my @dbs = ();
my ($c)=$dbh->prepare("SHOW DATABASES") or
die "Sql has gone to hell\n";
if(not ($c->execute())) {
my $err=$dbh->errstr;
return undef;
}
(@dbs)=$c->fetchrow();
$c->finish();
return @dbs;
}
sub closeSessions {
warn "close sessions";
Thread->new(\&execute())->join() foreach @dbs;
}
sub execute {
my $db = shift || '';
warn $db ." current \n";
my $dbh = DBI->connect($db, $db_user, $db_password);
if (!$dbh->do("UPDATE sessionlist SET status='lost' WHERE moddate <
DATE_SUB(NOW() , '60 Minute' AND status='open'")) {
my $err=$dbh->errstr;
}
}
