首先在ORACLE用戶下進入.bash_profile文件
[oracle@linux02 ~]$ vi .bash_profile
export ORACLE_SID=hldb
export ORACLE_UNQNAME=hldb
將ORACLE_SID和ORACLE_UNQNAME修改為新的數據庫名字
[oracle@linux02 ~]$ source .bash_profile
刷新文件
----------------------------------------------------------------------------------------------------------
進入/u01/app/oracle/oradata目錄下
[oracle@linux02 oradata]$ cd /u01/app/oracle/oradata
[oracle@linux02 oradata]$ pwd
/u01/app/oracle/oradata
新建一個文件夾
[oracle@linux02 oradata]$ mkdir hldb
進入$ORACLE_HOME/dbs
[oracle@linux02 ~]$ cd $ORACLE_HOME/dbs
創建密碼文件
[oracle@linux02 dbs]$ orapwd file=orapwhldb password=oracle
建立一個新的參數文件並寫入相關信息
[oracle@linux02 dbs]$ vi inithldb.ora
DB_NAME='hldb'
CONTROL_FILES='/u01/app/oracle/oradata/hldb/control01.ctl'
MEMORY_TARGET=900M
---------------------------------------------------------------------------
以SYS身份啟動sqlplus
[oracle@linux02 dbs]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Mon Apr 23 10:03:27 2018
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to an idle instance.
創建spfile文件
SQL> create spfile from pfile;
File created.
啟動實例，不加載數據庫
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
分別執行以下命令
@?/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 在本會話框里切成VDEDU這個數據庫
select instance_name from v$instance;查詢當前數據庫實例的名字
shutdown immediate;關閉數據庫
