--- Step Menginstall Modul

1. Install composer (apabila belum terinstall) dengan command :
   ~$ apt-get install composer

2. Setelah composer terinstall lalu selanjutnya install modul oci dengan command :
   ~$ composer require professionalweb/oci8Pdo "dev-master"

3. Tambahkan class "professionalweb\oci8Pdo\Connection" sebagai pdo package, contoh : 
   'class' => 'professionalweb\oci8Pdo\Connection'
   
4. Pada konfigurasi database tambahkan parameter untuk melakukan cache schema :
    'enableQueryCache' => false,
    'enableSchemaCache' => true,
    'schemaCache' => 'cache',
    'schemaCacheDuration' => 0,
    'queryCacheDuration' => 3600,
	
5. Contoh full konfigurasi : 

	<?php
	$dsn = "TNS";
	return [
		'class' => 'professionalweb\oci8Pdo\Connection',
		'dsn' => 'oci:dbname=' . $dsn . ';',
		'username' => 'username',
		'password' => 'password',
		'enableQueryCache' => false,
		'enableSchemaCache' => true,
		'schemaCache' => 'cache',
		'schemaCacheDuration' => 0,
		'queryCacheDuration' => 3600,
		'on afterOpen' => function ($event) {
			$event->sender->createCommand("ALTER SESSION SET NLS_DATE_FORMAT = 'MM/DD/YYYY HH24:MI:SS'")->execute();
		}
	];
