Inheritance	yii\mutex\OracleMutex » yii\mutex\DbMutex » yii\mutex\Mutex » yii\base\Component » yii\base\BaseObject
Implements	yii\base\Configurable
Available since version	2.0.10
Source Code	https://github.com/yiisoft/yii2/blob/master/framework/mutex/OracleMutex.php

OracleMutex implements mutex "lock" mechanism via Oracle locks.

Application configuration example:

[
    'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'oci:dbname=LOCAL_XE',
             ...
        ]
        'mutex' => [
            'class' => 'yii\mutex\OracleMutex',
            'lockMode' => 'NL_MODE',
            'releaseOnCommit' => true,
             ...
        ],
    ],
]
