Create database 创建数据库

首先在ORACLE用户下进入.bash_profile文件

[oracle@linux02 ~]$ vi .bash_profile
export ORACLE_SID=hldb
export ORACLE_UNQNAME=hldb

将ORACLE_SID和ORACLE_UNQNAME修改为新的数据库名字

[oracle@linux02 ~]$ source .bash_profile

刷新文件

----------------------------------------------------------------------------------------------------------

进入/u01/app/oracle/oradata目录下

[oracle@linux02 oradata]$ cd /u01/app/oracle/oradata
[oracle@linux02 oradata]$ pwd
/u01/app/oracle/oradata

新建一个文件夹
[oracle@linux02 oradata]$ mkdir hldb

进入$ORACLE_HOME/dbs

[oracle@linux02 ~]$ cd $ORACLE_HOME/dbs

创建密码文件
[oracle@linux02 dbs]$ orapwd file=orapwhldb password=oracle

建立一个新的参数文件并写入相关信息

[oracle@linux02 dbs]$ vi inithldb.ora
DB_NAME='hldb'
CONTROL_FILES='/u01/app/oracle/oradata/hldb/control01.ctl'
MEMORY_TARGET=900M

---------------------------------------------------------------------------

以SYS身份启动sqlplus

[oracle@linux02 dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Mon Apr 23 10:03:27 2018

Connected to an idle instance.

创建spfile文件

SQL> create spfile from pfile;

File created.

启动实例，不加载数据库

SQL> startup nomount;
ORACLE instance started.

-------------------------------------------------------------------------------------------------
In SQL*Plus, connect to your Oracle Database instance with the SYSDBA administrative privilege:
[oracle@linux02 ~]$ sqlplus / as sysdba

分别执行以下命令

@?/rdbms/admin/catalog.sql
@?/rdbms/admin/catproc.sql
@?/rdbms/admin/utlrp.sql

In SQL*Plus, connect to your Oracle Database instance as SYSTEM user:
[oracle@linux02 ~]$ sqlplus system/oracle

@?/sqlplus/admin/pupbld.sql

-------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------
export ORACLE_SID=VDEDU 在本会话框里切成VDEDU这个数据库

select instance_name from v$instance;查询当前数据库实例的名字

shutdown immediate;关闭数据库
