添加表决盘（在ASM中）

注意事项：表决盘存在ASM注意事项
* 如果表决盘存放在ASM中，则表决文件的镜像，由磁盘组完成，不在需要另外一个磁盘组做镜像
* 不允许表决盘同时存在ASM和集群文件系统中。

OCR的备份

Oracle会自动备份，每隔4个小时。

手工备份

dump备份的ocr文件，会生成一个文件，查看生成文件

当集群出现问题的时候我们可以通过Import进行导入
但是需要很小心，有可能导致集群无法启动。如果要得到一个完整集群备份，需要全部关机采用导出导入。
ocrconfig -import ocrEXP

2种备份ocr的方法

方式一、
ocrconfig -manualbackup and  ocrconfig -restore
方式二、
ocrconfig -export and ocrconfig -import

注意：方式一是完全备份，方式二是不完全的。我们用方式一。注意方式一不能用方式二的导入。

表决盘备份作为OCR备份的一部分，表决盘自动备份自动恢复，表决盘全部丢失，需要人工干预。
