當(dāng)創(chuàng)建完畢oracle數(shù)據(jù)庫以及監(jiān)聽器時(shí)候，連接數(shù)據(jù)庫時(shí)會報(bào)如題錯(cuò)誤，只需要在D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN目錄下的listener.ora中添加如下語句即可：

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.


SID_LIST_LISTENER =
? (SID_LIST =
? ? (SID_DESC =
? ? ? (SID_NAME = CLRExtProc)
? ? ? (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
? ? ? (PROGRAM = extproc)
? ? ? (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
? ? )
? ? (SID_DESC =
? ? ? (GLOBAL_DBNAME = jcms)
? ? ? (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
? ? ? (SID_NAME = jcms)
? ? )
? )


LISTENER =
? (DESCRIPTION =
? ? (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.22.168)(PORT = 1521))
? )


ADR_BASE_LISTENER = D:\app\Administrator

其中紅色部分為手動(dòng)添加，然后重啟oracle服務(wù)以及監(jiān)聽器即可連接成功。
