Oracle11g em按钮乱码解决方法

从window下拷贝simsun.ttc字体文件到新建的$ mkdir $ORACLE_HOME/jdk/jre/lib/fonts/fallback目录下，然在更换名称为simsun.ttf,重启emctl

Oracle11g em Create

emca -config dbcontrol db -repos create

可能在Oracle DB10g 中会经常遇到OEM不能正常使用的问题,导致问题的原因不尽相同,

但最后绝大多数问题可以通过emca 这个命令来解决,详细的说明可以查看连机帮助,
下面给出一些常用的命令,及实例步骤.

创建一个EM资料库
    emca -repos create
重建一个EM资料库
    emca -repos recreate
删除一个EM资料库
    emca -repos drop
配置数据库的 Database Control
    emca -config dbcontrol db
删除数据库的 Database Control配置
    emca -deconfig dbcontrol db
重新配置db control的端口，默认端口在1158
    emca -reconfig ports
    emca -reconfig ports -dbcontrol_http_port 1160
    emca -reconfig ports -agent_port 3940
先设置ORACLE_SID环境变量后,启动EM console服务 
    emctl start dbconsole
先设置ORACLE_SID环境变量后,停止EM console服务
    emctl stop dbconsole
先设置ORACLE_SID环境变量后,查看EM console服务的状态
    emctl status dbconsole
配置dbconsole的步骤
    emca -repos create
    emca -config dbcontrol db
    emctl start dbconsole
重新配置dbconsole的步骤
    emca -repos drop
    emca -repos create
    emca -config dbcontrol db
    emctl start dbconsole

 

问题Example: 碰到ORACLE EM 无法启动，
问题Cause: 可能是IP更改了的原因，
问题Do:     所以使用了EMCA命令重新配置了一下ORACLE EM，
                   具体过程如下：

I:Documents and Settingsgeshaoqing>emca -config dbcontrol db -repos recreate
