1.数据库配置  apps/processmaker/htdocs/shared/sites/workflow/db.php   
修改  define ('DB_ADAPTER',     'mysql' ); 为define ('DB_ADAPTER',     'pdo' );

2.添加配置项 apps\processmaker\htdocs\gulliver\thirdparty\propel\adapter\DBAdapter.php    添加 'pdo' => 'DBPDO',
	private static $adapters = array(
								    'mysql' => 'DBMySQL',
									'mysqli' => 'DBMySQLi',
			                    'pdo' => 'DBPDO',
								    'mssql' => 'DBMSSQL',
								    'sybase' => 'DBSybase',
								    'oracle' => 'DBOracle',
								    'pgsql' => 'DBPostgres',
								    'sqlite' => 'DBSQLite',
                    'dbarray' => 'DBArray',
								    '' => 'DBNone',
	);

3. 创建PDO配置文件  apps\processmaker\htdocs\gulliver\thirdparty\propel\adapter\   
DBPDO.php

4.apps\processmaker\htdocs\gulliver\thirdparty\creole\Creole.php   添加pdo的drivers指向
    private static $driverMap = array(  'mysql' => 'creole.drivers.mysql.MySQLConnection',
                                        'mysqli' => 'creole.drivers.mysqli.MySQLiConnection',
                                        'pdo' => 'creole.drivers.pdo.PDOConnection',
                                        'pgsql' => 'creole.drivers.pgsql.PgSQLConnection',
                                        'sqlite' => 'creole.drivers.sqlite.SQLiteConnection',
                                        'oracle' => 'creole.drivers.oracle.OCI8Connection',
                                        'mssql' => 'creole.drivers.mssql.MSSQLConnection',
                                        'odbc' => 'creole.drivers.odbc.ODBCConnection'
                                       );

5.建立PDO文件夹,编写driver

6. apps\processmaker\htdocs\workflow\engine\src\ProcessMaker\Services\OAuth2\PmPdo.php 第37行添加一下内容。。因为其默认以配置的文件的type作为pdo连接头   
$connection['dsn'] = str_replace('pdo:','mysql:',$connection['dsn']);	

7.	apps/processmaker/htdocs/gulliver/system/下建立class.database_pdo.php		（此文件仅为文档上传文件用，实际代码可以copy mysql原版本）
class.database_pdo.php			   

8.pm_table，apps\processmaker\htdocs\workflow\engine\config 下创建配置文件，
propel.pdo.ini  （内容复制propel.mysql.ini，修改具体配置项）

9.apps\processmaker\htdocs\gulliver\thirdparty\propel-generator\classes\propel\engine\platform
添加PdoPlatform.php



10.apps\processmaker\htdocs\gulliver\thirdparty\propel-generator\classes\propel\engine\builder\sql
创建pdo文件夹，（copy mysql 里面内容修改为pdo所用参数） 

11. apps\processmaker\htdocs\workflow\engine\classes\class.pmTable.php  438行添加
if($dbEngine == 'pdo'){$dbEngine = 'mysql';}

12.apps\processmaker\htdocs\workflow\engine\src\ProcessMaker\Project
修正不能修改流程名字
