linux下配置oracle 10G EM Database Console

linux下配置oracle 10G EM Database Console[@more@]

1、啟動dbconsole

[oracle@devrfel501 ~]$ emctl start dbconsole

如果提示：OC4J Configuration issue. /opt/oracle/product/10.2.0/oc4j/j2ee/OC4J_DBConsol，則說明沒有配置或沒有建立

2、配置dbconsole

[oracle@devrfel501 ~]$ emca -config dbcontrol db

3、檢視dbconsole的狀態和訪問地址

[oracle@devrfel501 ~]$ emctl status dbconsole

TZ set to PRC
Oracle Enterprise Manager 10g Database Control Release 10.2.0.4.0
Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
https://devrfel501:5502/em/console/aboutApplication #訪問地址Oracle Enterprise Manager 10g is running.
------------------------------------------------------------------

4、刪除資料庫的 Database Control配置

oracle@devrfel501 ~]$ emca -deconfig dbcontrol db

5、常用的命令語法：

emca -repos create建立一個EM資料庫

emca -repos recreate重建一個EM資料庫

emca -repos drop刪除一個EM資料庫

emca -config dbcontrol db配置資料庫的 Database Control

emca -deconfig dbcontrol db刪除資料庫的 Database Control配置

emca -reconfig ports 重新配置db control和agent的埠

emctl start console啟動EM console服務，使用前需要先設定ORACLE_SID環境變數

emctl stop console停止EM console服務，使用前需要先設定ORACLE_SID環境變數

注：透過檢視$ORACLE_HOME/install/portlist.ini 檔案可以知道當前dbcontrol正在使用的埠，預設dbcontrol http埠1158，agent埠3938。如果要重新配置埠，可以使用如下命令：

emca -reconfig ports -dbcontrol_http_port 1159

emca -reconfig ports -agent_port 3939

使用命令列工具emctl可以啟動/停止console服務，察看服務狀態等。

===================================

====================================

如果用資料庫克隆到新機器上（不同的主機名）,訪問EM的時候可能發生如下錯誤:

java.lang.Exception: UnknownHostException sending request ::

要在控制檯輸入：

emca -config dbcontrol db -repos recreate
