LINUX下启动ORACLE

手动启动：
用 oracle用户登录（或su - oracle)
lsnrctl start 
sqlplus / as sysdba
  startup
  exit

自动启动，要编写一个启动脚本，用root用户拷到/etc/init.d下，取名叫oracle
然后, chkconfig oracle on，即可加入服务列表
/etc/init.d/oracle start   #启动
/etc/init.d/oracle stop  #停止
脚本的示例(里面的变量要按实际情况修改)：
#!/bin/bash 
#
# chkconfig:  345 99 01
# description: This is a program that is responsible for taking care of
# configuring the Oracle Database 11g Stardard/Enterprise Edition and its associated 
# services. 
#
