plsql连接oracle 及启动服务时候需要注意的问题

1.本地连接（windows）


ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )
2.本地连接（linux）
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
3.远程连接（windows）
GDS_192.168.1.9 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.9)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = GDS)
    )
  ) 
4.远程连接（linux）
GDS_192.168.1.10 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = GDS)
      (SERVER = DEDICATED)
    )
  )

修改文件的路径：D:\oracle\product\10.2.0\db_2\network\ADMIN
                                                      \tnsnames.ora  (文件名称)

安装oracle后需要注意的问题：断网安装的联网安装的启动服务的时候要对应
