oracle 10g rac hacmp 遷移到asm實驗步驟
1 實驗目的
oracle 11gR2版本開始在建庫選項中不支援裸裝置來建立資料庫，只能用共享檔案系統和asm來建立資料庫，不再支援raw來存放資料檔案。
很多客戶都是用裸裝置來管理資料庫,Oracle 提供了方法把裸裝置遷移到asm中，以下為具體的實驗步驟。
2 實驗環境和原來裸裝置資訊
遷移前的資料庫環境資訊
資料庫版本 環境 資料庫名 例項名 IP地址 作業系統和主機名
oracle10.2.0.4 hacmp5.5 orcl orcl1 192.168.3.225 aix6.1+p520
RAC orcl orcl2 192.168.3.223 aix6.1+p650
遷移後的資料庫環境資訊
資料庫版本 環境 資料庫名 例項名 IP地址 作業系統和主機名
資料庫版本 環境 資料庫名 例項名 IP地址 作業系統和主機名
oracle10.2.0.4 asm orcl orcl1 192.168.3.225 aix6.1+p520
RAC orcl orcl2 192.168.3.223 aix6.1+p650

control2_lv 資料庫控制檔案
control3_lv 資料庫控制檔案
spfile_lv 資料庫引數檔案
遷移到asm磁碟組資訊
磁碟組名稱 磁碟名稱 作用
hdisk11 ocr盤
hdisk10 vote盤
dgtest hdisk5 存放資料檔案，控制檔案，引數檔案，重做日誌檔案
hdisk6
hdisk7
3 實驗步驟
前提是hdisk5,hdisk6,hdisk7,hdisk10,hdisk11已經是從儲存中劃分到p520,p650節點上，並且賦予許可權給oracle使用者,並且兩邊節點先建立好asm例項和磁碟組dgtest。
3.1 遷移ocr盤到hdisk11磁碟中
線上做，不需要停crs
檢視當前ocr盤
[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
Cluster registry integrity check succeeded
對當前ocr盤增加鏡象
[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -replace ocrmirror /dev/rhdisk11
檢視鏡象後的ocr盤
ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 130852
Used space (kbytes) : 4636
Available space (kbytes) : 126216

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
從ocr盤去掉ocrnewlv裸裝置
[root@p520:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -replace ocr
檢視最後的設定,成功遷移到hdisk11磁碟中
[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

ID : 1542042236
Device/File Name : /dev/rhdisk11
Device/File integrity check succeeded
Device/File not configured
Cluster registry integrity check succeeded
3.2 遷移vote盤到hdisk10中
需要兩邊節點停止crs
檢視當前vote盤
[root@p520:/crs/app/oracle/product/crs_1/bin]#./crsctl query css votedisk
0. 0 /dev/rvotenewv
located 1 votedisk(s).
增加vote鏡象盤
[root@p520:/crs/app/oracle/product/crs_1/bin]#./crsctl add css votedisk '/dev/rhdisk10' -force
Now formatting voting disk: /dev/rhdisk10
successful addition of votedisk /dev/rhdisk10
檢視鏡象後的vote盤
[root@p520:/crs/app/oracle/product/crs_1/bin]#./crsctl query css votedisk
0. 0 /dev/rvotenewlv
1. 0 /dev/rhdisk10
從vote盤中刪除votenewlv裸裝置
[root@p520:/crs/app/oracle/product/crs_1/bin]#./crsctl delete css votedisk '/dev/rvotenewlv' -force
successful deletion of votedisk /dev/rvotenewlv
檢視最後vote盤，成功遷移到hdisk10磁碟中
[root@p650:/crs/app/oracle/product/crs_1/bin]#./crsctl query css votedisk
0. 0 /dev/rhdisk10
located 1 votedisk(s).
兩邊節點啟動crs
檢視兩邊節點資源狀態
crs_stat -t
3.3 設定引數到asm磁碟組中
控制檔案，資料檔案，和日誌檔案到磁碟中。
sqlplus “/as sysdba”
SQL> alter system set db_create_file_dest='+dgtest' scope=spfile;
System altered.
SQL> alter system set db_create_online_log_dest_1='+dgtest' scope=spfile;
System altered.
SQL> alter system set db_create_online_log_dest_2='+dgtest' scope=spfile;
System altered.
SQL> alter system set control_files='+dgtest/orcl/control01.ctl' scope=spfile;
System altered.
3.4 遷移控制檔案到磁碟組中
關閉p520例項，在p650例項中做遷移
關閉p650例項，啟動到nomount狀態，恢復控制檔案到asm磁碟組中
