Apache::Session::Lock:UseraContributed Perl DoApache::Session::Lock::Sybase(3)NAMEApache::Session::Lock::Sybase - Provides mutual exclusion using Sybase
SYNOPSIS
use Apache::Session::Lock::Sybase;
my $locker = new Apache::Session::Lock::Sybase;
$locker->acquire_read_lock($ref);
$locker->acquire_write_lock($ref);
$locker->release_read_lock($ref);
$locker->release_write_lock($ref);
$locker->release_all_locks($ref);
DESCRIPTIONApache::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.
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::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
};
