第四课 Grid Control实验安装JCH2库并且配置好监听，关键步骤和结果截图

--从OCM 虚拟机中，克隆了安装oracle之前的状态

配置网络：

[root@localhost network-scripts]# ifup ifcfg-eth0

[root@localhost network-scripts]# ifconfig

--安装JCH2 库作用：存放历史数据，用于历史分析

配置oracle用户环境变量

vi ~/.bash_profile

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH

配置主机名：

vi /etc/hosts

[root@localhost sysconfig]# vi network

[root@localhost sysconfig]# pwd

/etc/sysconfig

[root@localhost sysconfig]#

重启网络服务：

service network restart

给文件夹更换用户及组：

chown -R oracle:oinstall /u01

安装软件

切换到root用户：执行

/u01/app/oraInventory/orainstRoot.sh

/u01/app/oracle/product/10.2.0/db_1/root.sh

（linux知识：可以把oracle 放到 sudoer里面）

然后执行：sudo /u01/app/oraInventory/orainstRoot.sh

oracle is not in the sudoers file. This incident will be reported.

编辑 /etc/sudoers

加入下面一行，让oracle用户可以执行所有命令。

然后oracle用户登录就可以直接使用 sudo *******命令，执行root用户可以执行的命令了

oracle ALL=(ALL) ALL

修改sql提示符

vi /u01/app/oracle/product/10.2.0/db_1/sqlplus/admin/glogin.sql

装数据库

输入dbca

[oracle@ocm2 ~]$ dbca

Xlib: connection to ":0.0" refused by server

Xlib: No protocol specified

尝试修改了DISPLAY变量，仍然提示错误

后来发现只要直接用oracle用户登录，执行dbca就可以弹出窗口了

不要通过root su到oracle

em与gc只能选择一个。，所以这一步要取消em

下面的按钮图片没有显示出来：Standard Database Components:把jvm和XML DB关掉

创建监听

检查：

[oracle@ocm2 JCH2]$ vi /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora

修改tnsnames.ora

JCH1 =

(description =

(address=(protocol=tcp)(host=ocm1)(port=1521))

(connect_data=

(server = dedicated)

(service_name = JCH1)

)

JCH2 =

(description =

(address=(protocol=tcp)(host=ocm2)(port=1521))

(connect_data=

(server = dedicated)

(service_name = JCH2)

)

SYS@JCH2> create user jch2 identified by jch2;

User created.

SYS@JCH2> grant dba to jch2;

Grant succeeded.

SYS@JCH2>

修改listener.ora

修改后：

登录JCH2
