启动数据库实例,分为两步:第一步,启动监听;第二步,启动数据库实例。
进入到sqlplus启动实例
-
切换到oracle用户
[oracle@aiezfs bin]$ su - oracle
-
打开监听
[oracle@aiezfs bin]$ ./lsnrctl start LSNRCTL for Linux: Version 12.1.0.1.0 - Production on 07-OCT-2014 15:41:02 Copyright (c) 1991, 2013, Oracle. All rights reserved.

进入到sqlplus
[oracle@aiezfs bin]$ ./sqlplus /nolog SQL*Plus: Release 12.1.0.1.0 Production on Tue Oct 7 15:41:30 2014 Copyright (c) 1982, 2013, Oracle. All rights reserved.
-
通过sysdba连接
SQL> conn / as sysdba Connected to an idle instance.
-
启动数据库实例
SQL> startup ORACLE instance started. Total System Global Area 4.0486E+10 bytes Fixed Size 4658128 bytes Variable Size 5368712240 bytes Database Buffers 3.5031E+10 bytes Redo Buffers 82210816 bytes Database mounted. Database opened.
-
关闭数据库实例
SQL> shutdown immediate Database closed. Database dismounted. ORACLE instance shut down.
-
退出sql
SQL> exit Disconnected from Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options
-
关闭监听
[oracle@aiezfs bin]$ ./lsnrctl stop LSNRCTL for Linux: Version 12.1.0.1.0 - Production on 07-OCT-2014 16:39:54 Copyright (c) 1991, 2013, Oracle. All rights reserved. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) The command completed successfully
通过dbstart和dbshut启动和关闭数据库
-
启动监听 lsnrctl start,同上
-
启动实例
[oracle@aiezfs bin]$ ./dbstart ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener Usage: ./dbstart ORACLE_HOME
使用dbstart命令,需要指定变量ORACLE_HOME_LISTNER,此处等于ORACLE_HOME,可以在dbstart和dbshut脚本文件中,修改变量ORACLE_HOME_LISTNER的值。
ORACLE_HOME_LISTNER=$1,修改为
ORACLE_HOME_LISTNER=$ORACLE_HOME。修改后再执行./dbstart
