本次快速搭建單例項物理DataGuard，為解決某些同事擔心“那如果我在primary裡面使用提交的事務操作時按照rowid去檢索資料，到備庫執行的和主庫操作不一致”

資料庫軟體安裝過程不再贅述。

1: 檢查主庫否為 force logging .

select inst_id , force_logging from gv$database;
alter database force logging;

2:備庫建立資料庫例項 

oradim -new -sid tjcshow -startmode a

3:配置主/備庫tnsnames,listener

增加主庫TNSNAMES節點：

TJCSHOW1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.100.111.130)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = tjcshow)
    )
  )


TJCSHOW2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.100.111.131)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = tjcshow)
    )
  )
 

將主庫listener/SQLNET/TNSNAMES拷貝到備庫待用

修改監聽：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
    (GLOBAL_DBNAME = tjcshow)
    (ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
    (SID_NAME = tjcshow)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = DKD-O13022802)(PORT = 1521))
    )
  )
 

4：主庫生成pfile,拷貝到備庫作為基礎引數檔案,修改主/備庫pfile

1000條測試資料全部同步到備庫，且ROWID沒有發生變化。

Physical standby database  Provides a physically identical copy of the primary database, with on disk database structures that are identical to the primary database on a block-for-block basis. The database schema, including indexes, are the same. A physical standby database is kept synchronized with the primary database, through Redo Apply, which recovers the redo data received from the primary database and applies the redo to the physical standby database.

所以主庫到備庫的後的ROWID不會發生變化，所以同事的擔心沒有必要。做這件事情的同時想起exp/imp，expdp/impdp做備份還原的時候會修改rowid的值，所以如果所做的備份庫的應用中使用了ROWID，千萬不要使用exp/imp，expdp/impd做資料遷移。
