1.设定SID

ORACLE_SID=logdb

export ORACLE_SID

2. 设定其它环境变量

ORALCE_HOME，PATH等。

创建相关目录：

mkdir -p /u01/app/oracle/admin/logdb/adump

mkdir -p /u01/app/oracle/admin/logdb/bdump

mkdir -p /u01/app/oracle/admin/logdb/cdump

mkdir -p /u01/app/oracle/admin/logdb/udump

3.选择数据库管理员的授权方式

选择密码文件方式。

orapwd file=$ORACLE_HOME/dbs/orapwlogdb password=admin entries=5 force=y

file参数必须说明全路径。

Table 1-1 Required Password File Name and Location on UNIX, Linux, and Windows

PlatformRequired Name    Required Location)

UNIX and LinuxorapwORACLE_SID    ORACLE_HOME/dbs

Windows        PWDORACLE_SID.ora   ORACLE_HOME\database

4.创建初始化参数文件

Platform  Default Name                              Default Location

UNIX and Linux  initORACLE_SID.ora                          ORACLE_HOME/dbs

For example, the initialization parameter

file for the mynewdb database is named:

initmynewdb.ora

Windows          initORACLE_SID.ora                      ORACLE_HOME\database

# Change '' to point to the oracle base (the one you specify at

# install time)

db_name='logdb'    #不要超过8个字符

memory_target=8G

processes = 500

audit_file_dest='/u01/app/oracle/admin/logdb/adump'

audit_trail ='db'

db_block_size=32768

db_domain=''

service_name='logdbsvc'

instance_name='logdb'

local_listener='logdb_listener'   #在tnsname.ora中该定义连接串

#db_recovery_file_dest='/flash_recovery_area'

#db_recovery_file_dest_size=2G

diagnostic_dest='/u01/app/oracle'

dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'

open_cursors=300

remote_login_passwordfile='EXCLUSIVE'

undo_tablespace='UNDOTBS1'

# You may want to ensure that control files are created on separate physical

# devices

control_files = ('+CRS/logdb/controlfile/ora_control1','+CRS/logdb/controlfile/ora_control2')

compatible ='11.2.0'

log_archive_dest_1='LOCATION=+CRS'

background_dump_dest=/u01/app/oracle/admin/logdb/bdump

core_dump_dest=/u01/app/oracle/admin/logdb/cdump

user_dump_dest=/u01/app/oracle/admin/logdb/udump

5.连接到instance

$ sqlplus /nolog

SQL> CONNECT SYS AS SYSDBA

6.创建服务器参数文件(spfile)

CREATE SPFILE FROM PFILE;

7.启动instance

STARTUP NOMOUNT;

8.执行创建数据库命令

CREATE DATABASE logdb

USER SYS IDENTIFIED BY sys_password

USER SYSTEM IDENTIFIED BY system_password

LOGFILE GROUP 1 ('/u01/logs/my/redo01a.log','/u02/logs/my/redo01b.log') SIZE 100M BLOCKSIZE 512,

GROUP 2 ('/u01/logs/my/redo02a.log','/u02/logs/my/redo02b.log') SIZE 100M BLOCKSIZE 512,

GROUP 3 ('/u01/logs/my/redo03a.log','/u02/logs/my/redo03b.log') SIZE 100M BLOCKSIZE 512

MAXLOGFILES 5
