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

	use Apache::Session::Lock::Sybase;

	my $locker = new Apache::Session::Lock::Sybase;


       Apache::Session::Lock::Sybase fulfills the locking interface of Apache::Session.  Mutual
       exclusion is achieved through the use of Sybase's sp_getapplock and sp_releaseapplock
       functions. Sybase 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.

       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::Sybase.	Example:

	tie %hash, 'Apache::Session::Sybase', $id, {
	    LockDataSource => 'dbi:sybase:database',
	    LockUserName   => 'database_user',
	    LockPassword   => 'K00l'

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

	tie %hash, 'Apache::Session::Sybase', $id, {
	    LockHandle => $dbh

       This module was written by Oliver Maul <oli@42.nu>.
