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）
