OCR镜像的增加及删除

OCR记录节点成员的配置信息,如ASM、instance、listener、VIP等CRS资源的配置信息

检查OCR的状态
[root@node3 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     208656
         Used space (kbytes)      :       6496
         Available space (kbytes) :     202160
         ID                       :  844916878
         Device/File Name         : /dev/raw/raw2
                                    Device/File integrity check succeeded

                                    Device/File not configured

         Cluster registry integrity check succeeded

[root@node3 ~]# cat /etc/oracle/ocr.loc
#Device/file /dev/raw/raw4 being deleted
ocrconfig_loc=/dev/raw/raw2
local_only=false

 

增加一个镜像

 

[root@node3 ~]# ocrconfig -replace ocrmirror /dev/raw/raw4
[root@node3 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     208656
         Used space (kbytes)      :       6496
         Available space (kbytes) :     202160
         ID                       :  844916878
         Device/File Name         : /dev/raw/raw2
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/raw/raw4
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

[root@node3 ~]# cat /etc/oracle/ocr.loc
#Device/file  getting replaced by device /dev/raw/raw4
ocrconfig_loc=/dev/raw/raw2
ocrmirrorconfig_loc=/dev/raw/raw4
local_only=false

[root@node3 ~]# ocrconfig -replace ocrmirror /dev/raw/raw6
[root@node3 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     208656
         Used space (kbytes)      :       6496
         Available space (kbytes) :     202160
         ID                       :  844916878
         Device/File Name         : /dev/raw/raw2
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/raw/raw6
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

[root@node3 ~]# cat /etc/oracle/ocr.loc
#Device/file /dev/raw/raw4 getting replaced by device /dev/raw/raw6
ocrconfig_loc=/dev/raw/raw2
ocrmirrorconfig_loc=/dev/raw/raw6
local_only=false

OCR只能有一份镜像，新增加的镜像文件会替换掉原来的镜像。

删除OCR的镜像文件

 

[root@node3 ~]# ocrconfig -replace ocrmirror   ---不带文件路径名
[root@node3 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     208656
         Used space (kbytes)      :       6496
         Available space (kbytes) :     202160
         ID                       :  844916878
         Device/File Name         : /dev/raw/raw2
                                    Device/File integrity check succeeded

                                    Device/File not configured

         Cluster registry integrity check succeeded

[root@node3 ~]# cat /etc/oracle/ocr.loc
#Device/file /dev/raw/raw6 being deleted
ocrconfig_loc=/dev/raw/raw2
local_only=false
 

注意如果我们删除了OCR的主文件,相应的镜像文件自动的变为主文件。
例如：
[root@node3 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     208656
         Used space (kbytes)      :       6496
         Available space (kbytes) :     202160
         ID                       :  844916878
         Device/File Name         : /dev/raw/raw2
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/raw/raw4
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded
[root@node3 ~]# ocrconfig -replace ocr
[root@node3 ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     208656
         Used space (kbytes)      :       6496
         Available space (kbytes) :     202160
         ID                       :  844916878
         Device/File Name         : /dev/raw/raw4
                                    Device/File integrity check succeeded

                                    Device/File not configured

         Cluster registry integrity check succeeded
