oracle 10g 如何對ocr盤增加映象和刪除映象

            在oracle 10g ac cluster安裝初始階段，會有視窗提示你對ocr盤選擇映象或不做映象，如果在安裝時我們只規劃了一個ocr盤，如何在安裝完後增加映象和刪除映象，以下為具體步驟:

第一.增加/dev/rocr2_lv映象:

    crs叢集狀態已經啟動，並且資料庫也已經啟動

1.檢視ocr盤狀態

[root@p650:/crs/app/oracle/product/crs_1]#cd bin
[root@p650:/crs/app/oracle/product/crs_1/bin]#pwd
/crs/app/oracle/product/crs_1/bin
[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     130852
         Used space (kbytes)      :       3280
         Available space (kbytes) :     127572
         ID                       :  614588822
         Device/File Name         : /dev/rocrlv
                                    Device/File integrity check succeeded

                                    Device/File not configured

         Cluster registry integrity check succeeded

從上面可以看出，只有一個ocr盤

2.從作業系統上增加ocr盤，必須是兩邊節點都可以看到的共享盤

smitty mklv   lv名字為/dev/rocr2_lv

chown root:ointall /dev/rocr2_lv

chmod 640 /dev/rocr2_lv

3.crs叢集中增加ocr盤，用ocrconfig命令

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -replace ocrmirror /dev/rocr2_lv

4.檢查結果

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     130852
         Used space (kbytes)      :       3280
         Available space (kbytes) :     127572
         ID                       :  614588822
         Device/File Name         : /dev/rocrlv
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/rocr2_lv
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

[root@p650:/etc]#cd oracle
[root@p650:/etc/oracle]#ls
ocr.loc   oprocd    scls_scr
[root@p650:/etc/oracle]#more ocr.locl
ocr.locl: A file or directory in the path name does not exist.
[root@p650:/etc/oracle]#more ocr.loc
#Device/file  getting replaced by device /dev/rocr2_lv
ocrconfig_loc=/dev/rocrlv
ocrmirrorconfig_loc=/dev/rocr2_lv
local_only=false
[root@p650:/etc/oracle]#
       ocr.loc檔案記錄ocr盤路徑

 

 第二.刪除/dev/rocr2_lv映象:

1.crs叢集中刪除ocr映象盤，用ocrconfig命令

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -replace ocrmirror

2.檢查結果

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     130852
         Used space (kbytes)      :       3280
         Available space (kbytes) :     127572
         ID                       :  614588822
         Device/File Name         : /dev/rocrlv
                                    Device/File integrity check succeeded

                                    Device/File not configured

         Cluster registry integrity check succeeded

 

root@p650:/etc/oracle]#more ocr.loc
ocrconfig_loc=/dev/rocrlv
local_only=false
[root@p650:/etc/oracle]#

刪除/dev/rocr2_lv成功
