Oracle数据库的连接配置（学习笔记）

配置Oracle:

1）如果本机已经安装过Oracle，路径为"安装路径:\oracle\product\10.1.0\Client_1\NETWORK\ADMIN\"

2) 如果本机未安装过Oracle，路径为"C:\Oracle\ora90\network\ADMIN\"

路径下有一个listener.ora和tnsnames.ora

用记事本打开tnsnames.ora，修改其中的路径和服务器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)
)
)

打开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))
)
