關閉

1.先關數據庫：

代碼如下:

[oracle@oeltan1 ~]$ srvctl stop database -d tantest

2.再關閉crs服務

代碼如下:

root@oeltan1 ~]# crsctl stop crs

啟動：

代碼如下:

[root@oeltan1 ~]# crsctl start crs

[oracle@oeltan1 ~]$srvctl start asm -n node_name

上述開機一般已經啟動

代碼如下:

[oracle@oeltan1 ~]$ srvctl start database -d tantest

歸檔設置：

1. 分別創建兩個實例的ASM目錄

任意一個實例，grid用戶下：

代碼如下:

# su - grid

[grid@oeltan1 ~]$ sqlplus "/as sysasm"

SQL> select name from V$asm_diskgroup;

NAME

--------------------------------------------------------------------------------

CRS

DATA1

FRI

12 SQL> alter diskgroup FRI add directory '+FRI/TANTEST'; SQL> alter diskgroup FRI add directory '+FRI/TANTEST/ARCH1';

還可以通過asmcmd創建目錄：

123 ASMCMD> pwd +FRI/TANTEST ASMCMD> mkdir ARCH2

2.修改歸檔參數

任意一個實例,oracle用戶下：

12 ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH1' SCOPE=both SID='tantest1'; ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH2' SCOPE=both SID='tantest2';

3.兩個節點上分別都執行：

1234 SQL> SHUTDOWN IMMEDIATE; SQL> STARTUP MOUNT; SQL> ALTER DATABASE ARCHIVELOG; SQL> ALTER DATABASE OPEN;

--修改一個實例時，另一個實例不能在open狀態，否則報ORA-01126: database must be mounted in this instance and not open in any

4.分別檢查：

12345678910111213141516 SQL> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination +FRI/tantest/arch1 Oldest online log sequence 14 Next log sequence to archive 15 Current log sequence 15 SQL> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination +FRI/tantest/arch2 Oldest online log sequence 6 Next log sequence to archive 7 Current log sequence 7 SQL>
