$ chmod +x jdk-6u45-linux-x64.bin
$ ./jdk-6u45-linux-x64.bin
$ mv jdk1.6.0_45/ /u01/weblogic/修改oracle用户环境变量
$ su - oracle
$ vim ~/.bash_profileexport JAVA_HOME=/u01/weblogic/jdk1.6.0_45
PATH=$PATH:/u01/weblogic/jdk1.6.0_45/bin:/u01/weblogic/jdk1.6.0_45/jre/bin修改oracle用户.bashrc 文件，添加：
export JAVA_HOME=/u01/weblogic/jdk1.6.0_45
export PATH=$JAVA_HOME/bin:$PATH执行测试
$ source ~/.bashrc
$ java -version

4.2 OMS配置管理
查看版本：
$ /emctl getversion oms
查看状态：
$ /emctl status oms
查看oms详细信息：
$ /emctl status oms –details
指定密码查看详细：
$ /emctl status oms -details -sysman_pwd Oracle123
查看属性：
$ /emctl list properties
启停命令：
$ /emctl stop oms
$ /emctl start oms 修改内存（重启生效）：
1.命令修改：
$ /emctl get property -name OMS_HEAP_MAX -sysman_pwd Oracle11g
$ /emctl set property -name OMS_HEAP_MAX -value 2048M -sysman_pwd Oracle11g
$ /emctl get property -name OMS_HEAP_MIN -sysman_pwd Oracle11g
$ /emctl set property -name OMS_HEAP_MIN -value 512M -sysman_pwd Oracle11g
2. 直接修改属性配置文件：emgc.properties
4.3 agent配置管理
查看版本：
$ /emctl getversion agent（查看版本）
启停与查看状态：
$ /emctl status agent
$ /emctl stop agent
$ /emctl start agent
测试agent是否与OMS连通：
$ /emctl pingOMS
上传agent至服务端OMS
$ /emctl upload agent 5. 添加主机
配置hosts解析（源端和目标端）
vim /etc/hosts
network.ip hostname设置 -- 添加目标 -- 手动添加目标
6. 添加数据库
