OPatchAuto 自动调用 datapatch 完成安装数据库的二进制补丁并自动开始 post patch 的操作。
企业管理云控制（Enterprise Manager Cloud Control）
从 12.1 版本开始，EMCC 现在调用 datapatch 来完成任何 12c 或者更高版本的数据库补丁及 post patch 的操作
升级脚本使用Catctl.pl来替代原来的catupgrd.sql，DBUA 现在在升级过程中也调用 Datapatch
Datapatch 与 OPatch 的最大区别是 OPatch 在数据库关闭时执行，而 datapatch 是在数据库是打开时完成其动作的。
请看一个简单的示例：
[oracle@slcc20db01 OPatch]$ ls ---11G没有datapatch这个工具。
