Apache::Session::Lock::MySQL(3pm)			User Contributed Perl Documentation			 Apache::Session::Lock::MySQL(3pm)

NAME

       Apache::Session::Lock::MySQL - Provides mutual exclusion using MySQL

SYNOPSIS

	use Apache::Session::Lock::MySQL;

	my $locker = Apache::Session::Lock::MySQL->new();

	$locker->acquire_read_lock($ref);
	$locker->acquire_write_lock($ref);
	$locker->release_read_lock($ref);
	$locker->release_write_lock($ref);
	$locker->release_all_locks($ref);

DESCRIPTION

       Apache::Session::Lock::MySQL fulfills the locking interface of Apache::Session.	Mutual exclusion is achieved through the use of MySQL's
       GET_LOCK and RELEASE_LOCK functions.  MySQL does not support the notion of read and write locks, so this module only supports exclusive
       locks.  When you request a shared read lock, it is instead promoted to an exclusive write lock.

CONFIGURATION

       The module must know how to connect to your MySQL database to acquire locks.  You must provide a datasource name, a user name, and a
       password.  These options are passed in the usual Apache::Session style, and are very similar to the options for
       Apache::Session::Store::MySQL.  Example:

	tie %hash, 'Apache::Session::MySQL', $id, {
	    LockDataSource => 'dbi:mysql:database',
	    LockUserName   => 'database_user',
	    LockPassword   => 'K00l'
	};

       Instead, you may pass in an already opened DBI handle to your database.

	tie %hash, 'Apache::Session::MySQL', $id, {
	    LockHandle => $dbh
	};
