系统服务管理 ntsysv chkconfig

监听器已经启动，Plsql提示没有监听

用Net Configuration Assistant删除掉listener.ora和tnsnames.ora（或直接进入目录删除）

重新创建监听

创建后修改

listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = ORCL)
(ORACLE_HOME = d:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 改为计算机名称)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)

tnsnames.ora

ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = GBAFYC0D7XGNBI6)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)

注意一下，如果是11G，使用(sid = ORCL)

最后lsnrctl stop ,start ,status即可
