oracle 10g cluster 如何替換ocr主檔案 (crs online狀態)

     有時候我們需要把ocr檔案遷移到另外個地方,比如從這個vg下的ocr遷移到另外個vg下,或把ocr存放的裸裝置lv遷移到asm中

    實現方法很簡單,先增加ocr鏡象,然後刪除主ocr檔案,修改情況是在crs online狀態下的.。

     下面實現的是ocr裸裝置遷移到asm磁碟中

1.給新增的ocr鏡象賦予oracle許可權

2.增加鏡象盤

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -replace ocrmirror /dev/rhdisk11
[root@p650:/crs/app/oracle/product/crs_1/bin]#

[root@p650:/dev]#su - oracle
[oracle@p650:/oracle/app/oracle]$ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     130852
         Used space (kbytes)      :       4636
         Available space (kbytes) :     126216
         ID                       : 1542042236
         Device/File Name         : /dev/rocrnewlv
                                    Device/File integrity check succeeded
         Device/File Name         : /dev/rhdisk11
                                    Device/File integrity check succeeded

         Cluster registry integrity check succeeded

/dev/rocrnewlv 為以前的裸裝置盤

/dev/rhdisk11 為新增的鏡象asm盤

3.刪除ocr主鏡象盤

[root@p520:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -replace ocr

4.檢查結果

[root@p520:/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)      :       4636
         Available space (kbytes) :     126216
         ID                       : 1542042236
         Device/File Name         : /dev/rhdisk11
                                    Device/File integrity check succeeded

                                    Device/File not configured

         Cluster registry integrity check succeeded

[root@p520:/crs/app/oracle/product/crs_1/bin]#

遷移完畢
