修改listener.ora

listener.ora

SID_LIST_LISTENER =
   (SID_LIST =
(SID_DESC =
   (GLOBAL_DBNAME = demo)
   (ORACLE_HOME = D:/oracle/product/10.2.0/db_1)
   (SID_NAME = demo)
)
(SID_DESC =
   (GLOBAL_DBNAME = ORCL)
   (ORACLE_HOME = D:/oracle/product/10.2.0/db_1)
   (SID_NAME = ORCL)
)
   )

LISTENER =
   (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Colin)(PORT = 1521))
   )
