前言: 作为运维保障,都无法准确预估硬件宕机的突发阶段,其生产数据实时在产出,那作为dba数据库服务以及相关Listener的其重要性、必要性就突显而出。这里拿虚拟机试验做个配置记录,便于大家学习参考。
实现方法一:
环境变量值::$ORACLE_HOME= /data/oracle/product/11.2.0/db_1/
一、安装好Oracle数据库后: 完成配置执行dbstart和dbshut
[root@orcl3 ~]# su - oracle
[oracle@orcl3 ~]$ dbstart
ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener
Usage: /data/oracle/product/11.2.0/db_1/bin/dbstart ORACLE_HOME
错误原因:dbstart和dbshut脚本文件中ORACLE_HOME_LISTNER的设置有问题
[oracle@orcl3 ~]$ vim /data/oracle/product/11.2.0/db_1/bin/dbstart
[oracle@orcl3 ~]$ vim /data/oracle/product/11.2.0/db_1/bin/dbshut
分别打开两个文件找到以下行并修改:
ORACLE_HOME_LISTNER=$1
修改为:
ORACLE_HOME_LISTNER=$ORACLE_HOME
二、Linux启动时自动启动Oracle监听和实例
1、修改/etc/oratab文件
[root@orcl3 data]# vim /etc/oratab
找到: orcl:/data/oracle/product/11.2.0/db_1/:N
修改为: orcl:/data/oracle/product/11.2.0/db_1/:Y
#----------------------------#
如果没有/etc/oratab文件,需要执行以下步骤(如有可直接跳过此步骤)
Root下执行以下脚本,生成/etc/oratab文件
[root@orcl3 ~]# /data/oracle/product/11.2.0/db_1/root.sh
[root@orcl3 ~]# /data/oraInventory/orainstRoot.sh
[root@orcl3 ~]# /data/oracle/product/11.2.0/db_1/root.sh
