1、-- 查看服务器 ORA 环境变量情况
[oracle@orastb ~]$ env|grep ORA
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1

2、-- 创建参数文件
[oracle@orastb ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/dbs
[oracle@orastb dbs]$ ls
afiedt.buf hc_testdb.dat lkTESTDB2 spfiletestdb1.ora
hc_boncstb.dat inittestdb1.ora orapwboncstb spfiletestdb2.ora
hc_OMS.dat inittestdb2.ora orapwtestdb1
hc_testdb1.dat lkBONCSTB orapwtestdb2
hc_testdb2.dat lkTESTDB1 spfileboncstb.ora
[oracle@orastb dbs]$ touch initqixindb.ora
[oracle@orastb dbs]$ cat initqixindb.ora

memory_target=17179870000
*.db_name='QIXINDB'
*.processes = 300
*.audit_file_dest='/u01/app/oracle/admin/qixindb/adump'
*.audit_trail ='db'
*.db_block_size=8192
*.db_domain=''
*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
*.db_recovery_file_dest_size=10G
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
*.open_cursors=300 
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_tablespace='undotbs01'
# You may want to ensure that control files are created on separate physical
# devices
*.control_files='/oradata/qixindb/control01.ctl','/oradata/flash_recovery_area_qixindb/qixindb/control02.ctl'
*.compatible ='11.2.0'

3、-- 创建参数文件及建库所需目录 
[oracle@orastb dbs]$ mkdir -p /u01/app/oracle/admin/qixindb/adump
[oracle@orastb dbs]$ mkdir -p /u01/app/oracle/flash_recovery_area
[oracle@orastb dbs]$ mkdir -p /oradata/qixindb/
[oracle@orastb dbs]$ mkdir -p /oradata/flash_recovery_area_qixindb/qixindb/
[oracle@orastb dbs]$ mkdir -p /oradata/qixindb/redolog/

4、 -- 登录,启动数据库到nomount ， 执行手工建库脚本
[oracle@orastb ~]$ sqlplus / as sysdba
