oracle無法監(jiān)聽解決方案

 地域-幽靈 2010-03-11

1、解決方法
在oracle設(shè)置ODBC及出現(xiàn)oracle提示TNS:無監(jiān)聽程序的解決辦法
2009年10月16日 星期五 11:42
設(shè)置ODBC

    ODBC的全名是Open Database Connectivity(開放式數(shù)據(jù)庫連接),,是應(yīng)用程序連接數(shù)據(jù)庫的接口,。由于計算機(jī)的類型不同,從個人計算機(jī)到大型主機(jī),,都有自己處理數(shù)據(jù)的方式,,ODBC則可以連接到相同或不相同的數(shù)據(jù)庫管理系統(tǒng),因此,,ODBC可以給應(yīng)用程序提供相同的存取數(shù)據(jù)庫的接口,,程序設(shè)計員在設(shè)計連接不同數(shù)據(jù)庫時,只要處理與ODBC的連接就可以了,,而不必針對不同的數(shù)據(jù)庫設(shè)計完全不同的程序,。特別需要提醒的是,,不同的數(shù)據(jù)庫都有自己對應(yīng)的ODBC驅(qū)動程序,在使用不同數(shù)據(jù)庫的同時,,務(wù)必設(shè)置正確的ODBC驅(qū)動程序,。就像在本節(jié)中,,想要連接Oracle 10g數(shù)據(jù)庫,,就必須設(shè)置Oracle ODBC驅(qū)動程序,,操作步驟如下:
    (1)選擇Start→Programs→Oracle-OraDb10g_home1→Configuration and Migration Tools→Microsoft ODBC Administrator
    (2)打開ODBC Data Source Administrator,,
    (3)單擊System DSN標(biāo)簽
    (4)單擊Add按鈕
    (5)向下拖動滾動條,,找到Oracle in OraDb10g_home1選項,選擇該選項
    (6)單擊Finish按鈕,,進(jìn)入Oracle ODBC Driver Configuration對話框
    Data Source Name:自定義,,程序調(diào)用時將使用這個名稱,請輸入misdbdsn,。
    TNS Service Name:Oracle TNS服務(wù)名稱,,在創(chuàng)建數(shù)據(jù)庫時,一般默認(rèn)TNS服務(wù)名稱與數(shù)據(jù)庫名稱相同,,請輸入MISDB,,讀者也可以自定義。
    User ID:用戶的賬戶名稱,,這里使用System賬戶來測試,。
    (7)單擊Test Connection按鈕,出現(xiàn)Oracle ODBC Driver Connect對話框,,如圖13-10所示,。
    Password:請輸入安裝時給System設(shè)置的密碼,或自行修改后的密碼,。
如果出現(xiàn)oracle提示ERROR - ORA-12541: TNS:無監(jiān)聽程序,,那么就依照下列步驟做,這是因?yàn)槟愕姆峙涞牡刂凡粚Α?br>查看\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora文件,,用記事本打開,,顯示oracle值:
ORACLE =
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST =自動分配的IP地址)(PORT = 1521))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = oracle)
   )
)
主機(jī)名輸入localhost或127.0.0.1都會提示無監(jiān)聽程序。由于自動分配的IP地址會有變動,,所以將oralce值中的host改成本機(jī)的計算機(jī)名,,保存修改后的tnsnames.ora。再次新建數(shù)據(jù)庫,,出錯問題解決,。
# tnsnames.ora Network Configuration
File: G:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
ORACLE =
(DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST =計算機(jī)名稱)(PORT = 1521))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = oracle)
   )

計算機(jī)名稱可以右擊‘我的電腦’找到     
    (8)單擊OK按鈕
    (9)單擊OK按鈕,回到Oracle ODBC Driver Configuration對話框
    (10)單擊OK按鈕,,回到ODBC Data Source Administrator的System DNS選項卡
    (11)單擊OK按鈕,,完成ODBC的設(shè)置,。
2、解決方式:
<轉(zhuǎn)>改變oracle數(shù)據(jù)庫的ip地址引起的“ORA-12541:TNS:無監(jiān)聽程序”錯誤解決方法,!
2009-10-11 05:25 P.M.


在用PL/SQL Developer連接數(shù)據(jù)庫時出現(xiàn)
“ORA-12541:TNS:無監(jiān)聽程序”錯誤,。

1、檢查listener.log日志
發(fā)現(xiàn)下面錯誤:
TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 10:25:26
Copyright (c) 1991, 2005, Oracle. All rights reserved.
系統(tǒng)參數(shù)文件為D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
寫入D:\oracle\product\10.2.0\db_1\network\log\listener.log的日志信息
寫入D:\oracle\product\10.2.0\db_1\network\trace\listener.trc的跟蹤信息
跟蹤級別當(dāng)前為0
以 pid=1704 開始
監(jiān)聽: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\EXTPROC1ipc)))
監(jiān)聽該對象時出錯: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=0.5.0.5)(PORT=1521)))
TNS-12545: 因目標(biāo)主機(jī)或?qū)ο蟛淮嬖? 連接失敗
TNS-12560: TNS: 協(xié)議適配器錯誤
TNS-00515: 因目標(biāo)主機(jī)或?qū)ο蟛淮嬖? 連接失敗
32-bit Windows Error: 49: Unknown error
不再監(jiān)聽: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\EXTPROC1ipc)))

2,、查看Oracle的listener是否啟動
C:\Documents and Settings\mengzhaoliang>lsnrctl status
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 10:5
0:44
Copyright (c) 1991, 2005, Oracle. All rights reserved.
正在連接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
TNS-12541: TNS: 無監(jiān)聽程序
TNS-12560: TNS: 協(xié)議適配器錯誤
TNS-00511: 無監(jiān)聽程序
32-bit Windows Error: 2: No such file or directory
正在連接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=0.5.0.5)(PORT=1521)))
TNS-12535: TNS: 操作超時
TNS-12560: TNS: 協(xié)議適配器錯誤
TNS-00505: 操作超時
32-bit Windows Error: 60: Unknown error
原來沒有啟動listener,,用“lsnrctl start”命令也不能啟動。
C:\Documents and Settings\mengzhaoliang>lsnrctl start
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 10:5
2:16
Copyright (c) 1991, 2005, Oracle. All rights reserved.
啟動tnslsnr: 請稍候...
TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production
系統(tǒng)參數(shù)文件為D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
寫入D:\oracle\product\10.2.0\db_1\network\log\listener.log的日志信息
監(jiān)聽: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\EXTPROC1ipc)))
監(jiān)聽該對象時出錯: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=0.5.0.5)(PORT=1521))
)
TNS-12545: 因目標(biāo)主機(jī)或?qū)ο蟛淮嬖? 連接失敗
TNS-12560: TNS: 協(xié)議適配器錯誤
TNS-00515: 因目標(biāo)主機(jī)或?qū)ο蟛淮嬖? 連接失敗
32-bit Windows Error: 49: Unknown error
監(jiān)聽程序未能啟動,。請參閱上面的錯誤消息...
3,、查看listener.ora的內(nèi)容:
# listener.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 0.5.0.5)(PORT = 1521))
)
)
原來本機(jī)的ip發(fā)生改變后,就出現(xiàn)了上述問題,,改變數(shù)據(jù)庫的監(jiān)聽ip地址:
把(ADDRESS = (PROTOCOL = TCP)(HOST = 0.5.0.5)(PORT = 1521))
改成
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
127.0.0.1:也就是目前數(shù)據(jù)庫正在用的ip地址,。

4、再次啟動oracle的listener
C:\Documents and Settings\mengzhaoliang>lsnrctl start
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 20-9月 -2008 10:5
4:40
Copyright (c) 1991, 2005, Oracle. All rights reserved.
啟動tnslsnr: 請稍候...
TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production
系統(tǒng)參數(shù)文件為D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
寫入D:\oracle\product\10.2.0\db_1\network\log\listener.log的日志信息
監(jiān)聽: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\EXTPROC1ipc)))
監(jiān)聽: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1521)))
正在連接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
LISTENER 的 STATUS

例程 "PLSExtProc", 狀態(tài) UNKNOWN, 包含此服務(wù)的 1 個處理程序...
命令執(zhí)行成功
啟動已經(jīng)成功,,

5.再tnsnames.ora上添加上
ORCL_127.0.0.1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
6、再次用PL/SQL Developer再次連接數(shù)據(jù)庫
出現(xiàn)下面錯誤:
TNS-12514: TNS: 監(jiān)聽程序當(dāng)前無法識別連接描述符中請求的服務(wù)
再次檢查listener.log日志
20-9月 -2008 11:01:54 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl)(CID=

查看listener:

7,、用sqlplus也出現(xiàn)同樣錯誤:
C:\Documents and Settings\mengzhaoliang>sqlplusscott/mzl@ORCL_127.0.0.1
SQL*Plus: Release 10.2.0.1.0 - Production on 星期六 9月 20 11:15:09 2008

ERROR:

8、查看listenser狀態(tài):

2008 11:27:43
Copyright (c) 1997, 2005, Oracle. All rights reserved.
已使用的參數(shù)文件:
D:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora
TNS-03505: 無法解析名稱
9,、查看sqlnet.ora內(nèi)容:
# sqlnet.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
10.把listener.ora的內(nèi)容:
# listener.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
      (SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
)

改成下面的內(nèi)容:
# listener.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
      (SID_NAME = orcl)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
#      (PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = orcl))
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
)
11、然后關(guān)閉,、再啟動listener
在cmd中執(zhí)行“lsnrctl stop” 和“lsnrctl stop”命令,,再次登陸正常!
C:\Documents and Settings\mengzhaoliang>sqlplus scott/mzl@orcl
SQL*Plus: Release 10.2.0.1.0 - Production on 星期六 9月 20 11:55:47 2008

連接到:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options
SQL>

再次用PL/SQL Peveloper登陸就沒有問題了,。
完畢!
我通過以上步驟我的問題還沒解決,,然后重啟了一下OracleOraDb10g_home1TNSListener服務(wù)就行了
