RAC添加OCR 位置对OCR的修改会同步到节点上OCR的配置文件：ocr.loc。即使在另一个节点的crs关闭的情况下，在启动的时候也会自动更新OCR的变化。
添加语法如下：# ocrconfig -add +asm_disk_group | file_name
添加完成之后，使用命令验证#ocrcheck
查看ocr的位置[root@rac2 ~]# ocrcheckStatus of Oracle Cluster Registry is as follows :Version : 3Total space (kbytes) : 262120Used space (kbytes) : 3352Available space (kbytes) : 258768ID : 2129345179Device/File Name : +CRSDevice/File integrity check succeededDevice/File not configuredDevice/File not configuredDevice/File not configuredDevice/File not configuredCluster registry integrity check succeeded

将ocr添加到fra[root@rac1 ~]# ocrconfig -add +fra
验证[root@rac1 ~]# ocrcheckStatus of Oracle Cluster Registry is as follows :Version : 3Total space (kbytes) : 262120Used space (kbytes) : 3352Available space (kbytes) : 258768ID : 2129345179Device/File Name : +CRSDevice/File integrity check succeededDevice/File Name : +fraDevice/File integrity check succeededDevice/File not configuredDevice/File not configuredDevice/File not configuredCluster registry integrity check succeeded
查看配置文件是否跟新[root@rac1 ~]# cd /etc/oracle/[root@rac1 oracle]# cat ocr.loc#Device/file getting replaced by device +fraocrconfig_loc=+CRSocrmirrorconfig_loc=+fra
节点2验证[root@rac2 oracle]# cat ocr.loc#Device/file getting replaced by device +fraocrconfig_loc=+CRSocrmirrorconfig_loc=+fra
