为了新系统生效，需要重启OS
9、确认打完补丁，应用无异常
将APPLY状态改成COMMIT状态
10、如果应用异常，需要回退（步骤9不做）
回退安装AIX的补丁包
回退只能对在安装补丁包的过程中通过将选项“COMMIT software updates?”设置为“No”，并且“SAVE replaced files?”设置为“Yes”安装的补丁。否则只能做删除操作，而不能做回退操作。
1. 在系统中运行命令“smitty install”→“Software Maintenance and Utilities”→“Reject Applied Software Updates (Use Previous Version)”
2. 在“SOFTWARE name”按“ESC”+“4”显示选择菜单，通过按“ESC”+“7”选择需要回退的补丁，然后回车，如图2
3. 再回退前还是先模拟预览一下，将选项“PREVIEW only? (install operation will NOT occur)”改为“Yes”（用“ESC”+“4”选择），然后回车
4. 查看输出结果。输出结果为OK，则按“ESC”+“3”返回之前图2的界面。将选项“PREVIEW only? (install operation will NOT occur)”改为“No”，然后回车
5. 看到屏幕输出结果Ok，补丁即回退完毕。
6. 回退完毕后，按“ESC”+“0”返回到命令行界面。输入命令“lslpp –l|grep XXXX”（XXXX为回退的补丁filesets）可以查看filesets是否回退到之前的版本。
