從Oracle 10gR2開始,對于RAC數(shù)據(jù)庫設(shè)置歸檔模式非常方便,只需要在其中任何一個節(jié)點上操作,剩余節(jié)點instance關(guān)閉即可,下面是一個Oracle 10.2.0.2
版本2個節(jié)點的RAC數(shù)據(jù)庫打開歸檔模式的示例,歸檔存放在FRA磁盤組下的demo目錄下
第一步:規(guī)劃目錄
實例1的歸檔路徑：+FRA/demo/arch1
實例2的歸檔路徑：+FRA/demo/arch2
[oracle@rac02] /home/oracle> export ORACLE_SID=+ASM2
[oracle@rac02] /home/oracle> asmcmd
ASMCMD> ls
DATA/
FRA/
ASMCMD> cd FRA
ASMCMD> mkdir demo
ASMCMD> cd demo
ASMCMD> mkdir arch1 arch2
ASMCMD> ls -ltr
Type Redund Striped Time Sys Name
N arch1/
N arch2/
ASMCMD>
第二步：關(guān)閉實例2
[oracle@rac02] /home/oracle> sqlplus "/as sysdba"

SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - Production
With the Partitioning, Real Application Clusters, OLAP and Data Mining options
在節(jié)點1上確認實例2已經(jīng)關(guān)閉
[oracle@rac01] /home/oracle> crs_stat -t
Name Type Target State Host
------------------------------------------------------------

第三步：設(shè)置歸檔參數(shù)
在實例1上操作即可
[oracle@rac01] /home/oracle> sqlplus "/as sysdba"
SQL*Plus: Release 10.2.0.2.0 - Production on Sat Oct 9 18:07:51 2010

SQL> show parameter cluster_database

------------------------------------ ----------- ------------------------------
cluster_database boolean TRUE
cluster_database_instances integer 2

SQL> archive log list;
Database log mode No Archive Mode

Current log sequence 4
SQL> alter system set log_archive_dest_1='LOCATION=+FRA/demo/arch1' sid='demo1';

SQL> alter system set log_archive_dest_1='LOCATION=+FRA/demo/arch2' sid='demo2';
System altered.
SQL> show parameter log_archive_dest_1
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_1 string LOCATION=+FRA/demo/arch1
log_archive_dest_10 string
第四步：打開歸檔模式
繼續(xù)在實例1上操作
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.
Total System Global Area 218103808 bytes

SQL> archive log list;
Database log mode Archive Mode

Archive destination +FRA/demo/arch1
Oldest online log sequence 3
Next log sequence to archive 4
Current log sequence 4
SQL>
好了,到這里就按照我預(yù)先的規(guī)劃把這個2個節(jié)點的RAC數(shù)據(jù)庫打開到歸檔模式下了,歸檔文件存放在FRA磁盤組中.
第五步：打開剩余實例
[oracle@rac01] /home/oracle> crs_stat -t
