Oracle數據庫的連接配置（學習筆記）

配置Oracle:

1）如果本機已經安裝過Oracle，路徑爲"安裝路徑:\oracle\product\10.1.0\Client_1\NETWORK\ADMIN\"
2) 如果本機未安裝過Oracle，路徑爲"C:\Oracle\ora90\network\ADMIN\"

路徑下有一個listener.ora和tnsnames.ora
用記事本打開tnsnames.ora，修改其中的路徑和服務器IP地址，如下：

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

ORCL_172.39.8.7 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.39.8.7)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ORCL)
    )
  )

HRDS_172.39.8.215 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.39.8.215)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = HRDS)
    )
  )

打開listener.ora，修改如下：

# listener.ora Network Configuration File: D:\Oracle\product\10.1.0\Client_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_172.39.8.7_LISTER =
  (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = ORCL_172.39.8.7)
    (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
    (SID_NAME = ORCL)
  )

172.39.8.7_LISTER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.39.8.7)(PORT = 1521))
  )

SID_LIST_172.39.8.215_LISTER =
  (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = HRDS_172.39.8.215)
    (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
    (SID_NAME = ORCL)
  )

172.39.8.215_LISTER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.39.8.215)(PORT = 1521))
  )
