emctl start dbconsole遇到错误:OC4J_DBConsole_XXX _XXX not found.

发布时间:2020-08-08 13:45:33 来源:ITPUB博客 阅读:211 作者:迷倪小魏 栏目:关系型数据库


       想启动OracleOEM服务,运行emctl start dbconsole,结果出现如下报错信息:
       /u01/app/oracle/product/11.2.0/dbhome_1/oc4j/j2ee/OC4J_DBConsole_wjq.comsys.com_OraDB11g not found。要想打开OEMweb管理程序,必须先启动Database listener,再启动Datebase Control端口监控程序,但是碰到下面的问题:


[oracle@wjq ~]$ emctl start dbconsole

OC4J Configuration issue. /u01/app/oracle/product/11.2.0/dbhome_1/oc4j/j2ee/OC4J_DBConsole_wjq.comsys.com_OraDB11g not found.


其实产生的这样的情况,可能是em资料库配置不正确或者是dbcotrol没有配置好。


解决方法:   

①重建em资料

[oracle@wjq ~]$ emca -repos recreate

然后直接进入http://wjq.comsys.com:5500/em/,输入账户sys和密码******,选择sysdba权限,就能正常看到基于WEBEM了。

EM采用了web方式,并且分成了2个产品,database controlgrid controlGrid control需要下载单独的光盘安装。在用DBCA建库的时候,可以选择是否启用dbcontrol,启用的话需要在数据库中建立一个sysman schema,用于保存EM的一些数据,这个就是EM的资料库(repository)。使用命令行工具emca可以创建,修改,重建或者删除 dbcontrol的配置。


emca -repos create: 创建新的 Database Control 资料档案库
emca -repos drop:
删除当前的 Database Control 资料档案库
emca -repos recreate:
删除当前的 Database Control 资料档案库并重新创建一个
emca -config dbcontrol db
:配置数据库的 Database Control

emca -deconfig dbcontrol db:取消数据库的 Database Control


特别注意:

1)如果服务器上存在多个数据库,必须在启动Database control之前设置ORACLE_SID环境变量
2)最好使用静态IP地址来配置服务器



常用的命令语法:

emca -repos create创建一个EM资料库

emca -repos recreate重建一个EM资料库

emca -repos drop删除一个EM资料库

emca -config dbcontrol db配置数据库的 Database Control

emca -deconfig dbcontrol db删除数据库的 Database Control配置

emca -reconfig ports 重新配置db controlagent的端口

emctl start console启动EM console服务,使用前需要先设置ORACLE_SID环境变量

emctl stop console停止EM console服务,使用前需要先设置ORACLE_SID环境变量

注:通过查看$ORACLE_HOME/install/portlist.ini 文件可以知道当前dbcontrol正在使用的端口,默认dbcontrol http端口1158agent端口3938。如果要重新配置端口,可以使用如下命令:

emca -reconfig ports -dbcontrol_http_port 1159

emca -reconfig ports -agent_port 3939

使用命令行工具emctl可以启动/停止console服务,察看服务状态等。
