这篇文章主要介绍如何自动启动数据库，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
自动重启，需要grid的支持
自动管理资源
[oracle@edsir1p8-+ASM ~]$ crs_stat -t

ora.asm ora.asm.type ONLINE ONLINE edsir1p8
ora.cssd ora.cssd.type ONLINE ONLINE edsir1p8
ora.diskmon ora....on.type ONLINE ONLINE edsir1p8通常2种方式自动启动数据库
1.
[oracle@edsir1p8-+ASM ~]$ tail -3 /etc/oratab
PROD4:/u01/app/oracle/product/11.2.0/db_1:N
EMREP:/u01/app/oracle/product/11.2.0/db_1:N
+ASM:/u01/app/oracle/product/11.2.0/grid:N
---这种方式通常不好用2.crs_stat
这是个资源表，让数据库和监听注册到这个表里
[oracle@edsir1p8-+ASM ~]$ srvctl add database -d PROD4 -o /u01/app/oracle/product/11.2.0/db_1
[oracle@edsir1p8-+ASM ~]$ srvctl config database --查看哪些数据库已经注册关监听，注册
[oracle@edsir1p8-+ASM ~]$ srvctl add listener -l listener -p 1521 -o /u01/app/or
acle/product/11.2.0/db_1PRCN-2061 : Failed to add listener ora.LISTENER.lsnr
PRCN-2065 : Port(s) 1521 are not available on the nodes given
PRCN-2035 : Port 1521 is not available on node(s) or virtual host(s): edsir1p8.us.
oracle.com--关监听
[oracle@edsir1p8-+ASM ~]$ lsnrctl stop
[oracle@edsir1p8-+ASM ~]$ srvctl add listener -l listener -p 1521 -o /u01/app/oracle/pr
oduct/11.2.0/db_1
[oracle@edsir1p8-+ASM ~]$ srvctl config listener --查看监听是否注册成功[oracle@edsir1p8-+ASM ~]$ crs_stat -t

--集群管理的方式将数据库开
[oracle@edsir1p8-+ASM ~]$ srvctl start database -d PROD4
--执行相反操作
srvctl remove database -d PROD4 ---移除数据库
srvctl remove listener -l listener ---如果注册错误可以使用该命令删除以上是“如何自动启动数据库”这篇文章的所有内容，感谢各位的阅读！希望分享的内容对大家有帮助，更多相关知识，欢迎关注亿速云行业资讯频道！
