11.2OCR管理

如果期望把OCR存放到ASM磁盘上，ASM 的版本兼容必须设置为11.2.0.0。

If you upgrade from a previous version of Oracle Clusterware to 11g release 2 (11.2) and you want to store OCR in an Oracle ASM disk group, then you must set the ASM Compatibility compatibility attribute to 11.2.0.0.

除迁移的过程中，其他时候不允许把OCR存放到ASM上的同时，把OCR存放到其他的集群文件系统中。

Oracle does not support storing the OCR on different storage types simultaneously, such as storing OCR on both Oracle ASM and a shared file system, except during a migration.

在新的文件目录上添加OCR时，需确保文件已经存在。

If the original OCR location does not exist, then you must create an empty (0 byte) OCR location with appropriate permissions before you run the ocrconfig -add or ocrconfig -replace commands.

If you run the ocrconfig -add | -repair | -replace command, then the device, file, or Oracle ASM disk group that you are adding must be accessible. This means that a device must exist. You must create an empty (0 byte) OCR location, or the Oracle ASM disk group must exist and be mounted.
