listener.ora文件修改为
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E:\Oracle10gXEUniv\app\oracle\product\10.2.0\server)

(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = E:\Oracle10gXEUniv\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)

(SID_DESC =
(SID_NAME = XE)
(ORACLE_HOME = E:\Oracle10gXEUniv\app\oracle\product\10.2.0\server)

/*红色字体部分即为新加的数据库实例描述，注意该实例那样加(PROGRAM = extproc),否则会报“ORA-28547: TNS: 连接服务器失败，可能是Net8管理错误。”*/
