如果想要改变一个已经存在的ocr位置或改变一个已经出现故障的ocr位置，那么你就可以使用下面的过程来迁移ocr。

1.查看当前ocr情况

[oracle@node1 crs_1]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     153496
         Used space (kbytes)      :       3816
         Available space (kbytes) :     149680
         ID                       :  497615595
         Device/File Name         : /dev/raw/raw7
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/raw/raw8
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

这里raw7为普通ocr，raw8为镜像ocr
2.在Oracle clusterware 运行的节点上执行如下命令：

[oracle@node1 crs_1]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

3.迁移普通ocr

[root@node1 bin]# ./ocrconfig -replace ocr /dev/raw/raw9
[oracle@node1 crs_1]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     153496
         Used space (kbytes)      :       3816
         Available space (kbytes) :     149680
         ID                       :  497615595
         Device/File Name         : /dev/raw/raw9
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/raw/raw8
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

可以看到此时raw9已为普通ocr而非raw7

4.迁移镜像ocr

[root@node1 bin]# ./ocrconfig -replace ocrmirror /dev/raw/raw7
[oracle@node1 crs_1]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     153496
         Used space (kbytes)      :       3816
         Available space (kbytes) :     149680
         ID                       :  497615595
         Device/File Name         : /dev/raw/raw9
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/raw/raw7
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

可以看到此时raw7为镜像ocr而非raw8

5.如果做ocr迁移的时候有节点关闭，那么在启动关闭的节点后应该在这个节点上执行如下命令：

ocrconfig -repair
