oracle监听文件配置
pl/sql可以启动数据库，但是是myeclipse连接数据库报错，原因是数据库监听文件报错，即listener.ora配置出错，该文件正确的内容如下：
# listener.ora Network Configuration File: \app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = \app\Administrator\product\11.1.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = \app\Administrator\product\11.1.0\db_1)
(SID_NAME = ORCL)

(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
)
该文件端口号位1521，连接的位本机可以是127.0.0.1，也可以为localhost
