ORA-12505, TNS:listener does not currently know of SID given in connect

出现这个问题上网找了很久才解决问题是LISTENER配置问题

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E:\oracle\product\10)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = oracle)
(ORACLE_HOME = E:\oracle\product\10)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)

改成这样就OK了
