關(guān)閉

1.先關(guān)數(shù)據(jù)庫：

代碼如下:

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

2.再關(guān)閉crs服務(wù)

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(jīng)啟動

代碼如下:

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

歸檔設(shè)置：

1. 分別創(chuàng)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(chuàng)建目錄：

123 asmcmd> pwd +fri/tantest asmcmd> mkdir arch2

2.修改歸檔參數(shù)

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(jié)點上分別都執(zhí)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(tài)，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>
