linux不能自动启动oracle

王亮

1：查看ORACLE_HOME是否设置

$ echo $ORACLE_HOME

/u01/app/oracle/product/11.2.0/dbhome_1

2：执行dbstart数据库自带启动脚本

[oracle@orcl ~]$ cd $ORACLE_HOME[oracle@orcl dbhome_1]$ cd bin/[oracle@orcl bin]$ dbstartORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener Usage: /u01/app/oracle/product/11.2.0/db_1/bin/dbstart ORACLE_HOME错误提示：ORACLE_HOME_LISTNER 没有设置 [oracle@orcl bin]$ ll | grep dbs-rwxr-x---. 1 oracle oinstall 6088 1月 1 2000 dbshut-rwxr-x---. 1 oracle oinstall 13892 12月 11 16:01 dbstart 编辑 dbstart，将ORACLE_HOME_LISTNER=$1修改成 ORACLE_HOME_LISTNER=$ORACLE_HOME 前提是$ORACLE_HOME环境设置正确 [oracle@orcl bin]$ vi dbstart  ORACLE_HOME_LISTNER=/u01/app/oracle/product/11.2.0/dbhome_1

3：编辑/etc/oratab文件

dbca建库时都会自动创建/etc/oratab文件
将orcl:/u01/app/oracle/product/11.2.0/dbhome_1:N
修改成 orcl:/u01/app/oracle/product/11.2.0/dbhome_1:Y

4：编辑/etc/rc.d/rc.local启动文件，添加数据库启动脚本dbstart

[root@orcl ~]# vi /etc/rc.d/rc.local#!/bin/bash# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES## It is highly advisable to create own systemd services or udev rules# to run scripts during boot instead of using this file.## In contrast to previous versions due to parallel execution during boot# this script will NOT be run after all other services.## Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure# that this script will be executed during boot. touch /var/lock/subsys/localsu oracle -lc "/u01/app/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start"su oracle -lc /u01/app/oracle/product/11.2.0/dbhome_1/bin/dbstart

5：重启主机，查看数据库和监听是自启动

6：查看数据库是否处于open状态

select status from v$instance
