ora 12514 tns監聽程序當前無法識別

E:\oracle\NETWORK\ADMIN\listener.ora 還一個在同路徑下的tnsnames.ora文件（這是我自己的安裝路徑）

打開listener.ora：

# listener.ora Network Configuration File: E:\oracle\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E:\oracle)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = E:\oracle)
(SID_NAME = orcl)
)
)

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

標紅的是我新加的，然後重啟oracle服務就行了。
