oracle rac啟用歸檔模式
環境:
2個節點的RAC
資料庫版本:12.1.0.2.0
目的:
啟動歸檔日誌,同時將歸檔日誌存放到共享目錄(我這裡的是ASM磁碟組)
操作:
1、建立共享ASM磁碟組
C:\Users\Administrator>set ORACLE_HOME=E:\app\oraclehome\grid
C:\Users\Administrator>set ORACLE_SID=+ASM1
C:\Users\Administrator>asmcmd
ASMCMD> ls
DATA/
FRA/
OCR/
ASMCMD> cd fra
ASMCMD> pwd
+fra
ASMCMD> mkdir jiaxundb1
ASMCMD> mkdir jiaxundb2
ASMCMD> ls
jiaxundb1/
jiaxundb2/
2、檢視目前資料庫歸檔模式
C:\Users\Administrator>sqlplus / as sysdba

SQL> archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST

Current log sequence 90
SQL>
3、設定歸檔格式以及歸檔目的地
SQL> alter system set log_archive_format='%t_%s_%r.arch' scope=spfile sid='*';
System altered.
SQL> alter system set log_archive_dest_1='location=+fra/arch/jiaxundb1' scope=spfile sid='jiaxundb1';
System altered.
SQL> alter system set log_archive_dest_1='location=+fra/arch/jiaxundb2' scope=spfile sid='jiaxundb2';
System altered.
4、關閉所有例項
C:\Users\Administrator>srvctl stop database -d jiaxundb
5、將例項1啟動到Mount階段,並設定資料庫為歸檔模式
C:\Users\Administrator>sqlplus / as sysdba

6、啟動例項2,檢視資料庫歸檔模式是否正確
C:\Users\Administrator>sqlplus / as sysdba
SQL*Plus: Release 12.1.0.2.0 Production on 星期三 8月 17 15:35:30 2016

SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +FRA/arch/jiaxundb2
Oldest online log sequence 76
Next log sequence to archive 77
Current log sequence 77
SQL>
7、切換日誌組,驗證日誌是否被成功歸檔
SQL> alter system archive log current;
System altered.
ASMCMD> ls jiaxundb1
1_90_914678682.arch
1_91_914678682.arch
ASMCMD> ls jiaxundb2
2_77_914678682.arch
2_78_914678682.arch
OK,例項1和例項2已成功歸檔。
