10G RAC與10G Physical DG 的測試

測試環境
前期準備與規劃,主要的資料檔案放在+DATA,歸檔日誌放在+RECOVERY,預設RMAN備份集檔案放在+RECOVERY.
10G RAC為兩節點，Oracle版本10.2.0.5.0，OS Linux AS4U7，配置好RAC，並啟用歸檔,並且主庫啟用強制歸檔。
10G Physical DG為Oracle版本10.2.0.5.0，OS Linux AS4U7，安裝好與RAC完全相同版本的Oracle資料庫檔案，不要建立資料庫例項，監聽服務也不需要用netca額外建立。

vmrac3
pub 192.168.119.11/24 (NAT)
vip  192.168.119.13/24 (NAT)

vmrac4
pub 192.168.119.12/24 (NAT)
vip 192.168.119.14/24 (NAT)
private 10.10.10.12/24 (HOST)

vmrac34dg
192.168.119.25 (NAT)

RAC
SID:JTPROD1,JTPROD2
DB_NAME：JTPROD
DG  SID:JTPRODSB
DB_NAME：JTPROD

請注意:DG的SID可以與主庫一樣，也可以不用一樣，為了區分,我選擇與主庫不一樣進行配置，以免混淆.
這裡有5個名稱需要注意service_name,sid_name,global_name,db_unique_name,db_name，其中除db_name我們保持與主庫一致使用JTPROD，其他另外4個名稱我們均使用JTPRODSB,而這4個名稱為了能夠不混淆，建議名稱統一.

1,hosts檔案準備:有必要將主備庫的hosts檔案統一,以便使用hostname進行網路訪問,內容如下.
/etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost
192.168.119.25  vmrac34dg
192.168.119.21  vmrac3
192.168.119.22  vmrac4
10.10.10.21     vmrac3-priv

3,監聽檔案listener.ora
僅修改備庫的,內容如下.
/u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
SID_LIST_LISTENER =
    (SID_LIST =
        (SID_DESC =
        (GLOBAL_NAME = JTPRODSB)
        (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
        (SID_NAME = JTPRODSB))
)

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = vmrac34dg)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

4,引數檔案init$ORACLE_SID.ora
主備庫均要修改,備庫原本沒有引數檔案,通過修改主庫實現.
由主庫的引數檔案SQL>create pfile='/home/oracle/init.JTPROD.ora' from spfile;
對上述檔案進行修改得到備庫initJTPRODSB.ora的引數檔案.

經過刪除非*號開頭和有cluster字眼的部分行,新增或修改下面藍色部分,修改後為standby最後的引數檔案
initJTPRODSB.ora
control_files='/u01/oradata/control01.ctl','/u01/oradata/control02.ctl','/u01/oradata/control03.ctl'
log_archive_config='dg_config=(JTPROD,JTPRODSB)'

*.remote_login_passwordfile='exclusive'
*.sga_target=216006656
*.undo_management='AUTO'
*.user_dump_dest='/u01/app/oracle/admin/JTPRODSB/udump'

至此standby引數搞定,下面通過語句直接修改主庫的引數檔案.

主庫在任意RAC節點上修改即可.
SQL> alter system setlog_archive_config='dg_config=(JTPROD,JTPRODSB)' scope=spfile sid='*';
System altered.
SQL> alter system setlog_archive_dest_2='service=JTPRODSB valid_for=(online_logfiles,primary_role) db_unique_name=JTPRODSB';
System altered.
SQL> ALTER SYSTEM SETdb_file_name_convert='/u01/oradata','+DATA/JTPROD','/u01/oradata','+DATA/JTPROD' scope=spfile sid='*';
System altered.
SQL> alter system setlog_file_name_convert='/u01/oradata','+DATA/JTPROD' scope=spfile sid='*';
System altered.
SQL> ALTER SYSTEM SETstandby_file_management='AUTO';
System altered.
SQL> alter system setfal_server=JTPRODSB scope=spfile sid='*';
System altered.
SQL> ALTER SYSTEM SETfal_client=JTPROD scope=spfile sid='*';
System altered.

5,密碼檔案orapwJTPRODSB.ora
僅在備庫,拷貝主庫或重新建立均可orapwd file=/$ORACLE_HOME/dbs/orapwJTPRODSB password=amaxgs,注意這個密碼要和主庫一致.
