ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

在window7 64bit下安装oracle11g安装正常,安装完了以后使用也正常；

但在计算机重启后，重新登陆时就出现PL/SQL Deveplor

ORA-12514: TNS:listener does not currently know of service

requested in connect descriptor。

网上查下，用以下办法解决：

在安装目录下: /home/oracle/oracle/product/11.1.2/db_1/network/admin/listener.ora

将：SID_LIST_LISTENER=

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = E:\oracle\product\11.1.2\Db_1)

(PROGRAM =extproc)

)

)

改为：

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = E:\oracle\product\11.1.2\Db_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GOLBAL_DBNAME= orcl)

(ORACLE_HOME = E:\oracle\product\11.1.2\Db_1)

(SID_NAME=orcl)

)

)

然后重启服务和监听以后，登陆正常。
