Oracle 10g r2 rac + ASM 修改為歸檔狀態

Oracle 10g r2 rac資料庫修改歸檔到ASM

1，asm上建立相關空間目錄
 export ORACLE_SID=+ASM1
asmcmd
mkdir arch1 arch2

ASMCMD> pwd
+DATA/RACDB/archive
ASMCMD> ls
arch1/
arch2/
ASMCMD>

2，mount狀態下，在一個節點修改

[oracle@rac1 software]$ export ORACLE_SID=racdb1
[oracle@rac1 software]$ sqlplus "/as sysdba"

3,啟動另一個節點
[oracle@rac1 software]$ crs_start ora.racdb.racdb2.inst

4，驗證是否成功
node2執行

SQL> alter system archive log current;

System altered.

[oracle@rac2 ~]$ export ORACLE_SID=+ASM2
[oracle@rac2 ~]$ asmcmd
ASMCMD> ls
