11g RAC 更改歸檔模式 ,歸檔文件存放在ASM 磁盤組

11g RAC  更改歸檔模式   ASM

本實驗有兩個節點tip01,tip02
oracle_sid 分別是 tips1,tips2

1.在節點1 tip01上執行
[root@tip01 ~]# su - grid
[grid@tip01 ~]$ sqlplus  / as  sysasm

SQL> select name from v$asm_diskgroup;

NAME
------------------------------
DATA
OCR


SQL> alter diskgroup data add directory '+DATA/ARC1';

Diskgroup altered.


2.在節點1 tip02上執行
[root@tip01 ~]# su - grid
[grid@tip01 ~]$ sqlplus  / as  sysasm

SQL> select name from v$asm_diskgroup;

NAME
------------------------------
DATA
OCR


SQL> alter diskgroup data add directory '+DATA/ARC2';

Diskgroup altered.


執行完成後，退出ASM實例


3.在tip01上執行
[grid@tip01 ~]$ su - oracle
[oracle@tip01 ~]$ sqlplus  / as sysdba

SQL> SELECT INSTANCE_NAME FROM V$INSTANCE;

INSTANCE_NAME
----------------
tips1

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+DATA/ARC1' SCOPE=SPFILE SID='tips1';

System altered.

SQL>  ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+DATA/ARC2' SCOPE=SPFILE SID='tips2';

System altered.


4.關掉所有節點實例tips1,tips2服務

節點tip01上執行

SQL> SHUTDOWN IMMEDIATE

節點tip02上執行

SQL> SHUTDOWN IMMEDIATE


5.更改歸檔模式

節點tip01上執行

SQL> STARTUP MOUNT
SQL>ALTER DATABASE ARCHIVELOG;
Database altered.

SQL> archive log list
archive log list
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            +DATA/arc1
Oldest online log sequence     255
Next log sequence to archive   256
Current log sequence           256

節點tip01已經更改成功

節點tip02上執行

SQL> STARTUP MOUNT
SQL>ALTER DATABASE ARCHIVELOG;
Database altered.

SQL> archive log list
archive log list
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            +DATA/arc2
Oldest online log sequence     255
Next log sequence to archive   256
Current log sequence           256


6.打開數據庫

節點tip01,tip02上分別執行
SQL> alter database open


7.驗證歸檔文件

節點tip01上執行

SQL> alter system switch logfile;

System altered.


[oracle@tip01 ~]$ su - grid
[grid@tip01 ~]$ asmcmd
ASMCMD> ls
DATA/
OCR/
ASMCMD> cd DATA
ASMCMD> cd arc1
ASMCMD> ls
1_256_784611206.dbf



節點tip01 已經有歸檔文件產生了
