plsql+Oracle客户端连接本地Oracle和远程Oracle的方法

本地Oralce 客户端.ora文件配置容如下

tnsnames.ora

# tnsnames.ora Network Configuration File: D:\app\jkxt\product\11.2.0\client_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

JKXTORCL205 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.199.102.205)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = JKXTORCL)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )

JKXTORCL21 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.199.102.21)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = JKXTORCL)
    )
  )

　　

ORCL 为本地的oracle 数据库。

JKXTORCL205、JKXTORCL21为远程的Oracle数据库。

　本地oracle数据库lister.ora设置：

　　本地Oracle数据库的tnsnames.ora配置文件还有不明朗之处,应该是不用配置就可以访问远程的、本地的数据库。

其中上文中绿色代码不知道是不是必须的。红色代码为必须，否者远程Oracle数据库会报ORA-12154错误。
