在redhat linux环境下手工启动/关闭oracle 服务
在redhat linux环境下设置手工启动oracle 10g数据库
1、修改文件/oracle/product/10.2.0/db_1/bin/dbstart
# vi /oracle/product/10.2.0/db_1/bin/dbstart
将以下内容修改为：
oracle_home_listner=/oracle/product/10.2.0/db_1/（将oracle监听的路径修改正确）
2、修改文件etc/oratab （如果没有此文件，请执行/oracle/product/10.2.0/db_1目录下的root.sh文件,完成10g安装会提示你运行此脚本）
# vi etc/oratab --此用户必须是root
将以下内容修改：
siebeldb:/oracle/product/10.2.0/db_1:y --（将n修改成y，注意必须大写）
开始启动oracle数据库：
[oracle@crmdb ~]$ lsnrctl start
