Oracle用戶端實現負載平衡

 # tnsnames.ora Network Configuration File: D:\Oracle\product\10.1.0\Client_1\network\admin\tnsnames.ora
 # Generated by Oracle configuration tools.

一般配置

SERVER1=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = XX.X.X.XX4)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = SERVER1)
    )
  )
負載平衡

SERVER2=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = XX.X.X.X4)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = XX.X.X.X5)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = SERVER2)
    )
  )
註：首先要在把伺服器配置好這裡不作討論
