一：系统环境：Red Hat Enterprise Linux Server release 5.4

ORACLE版本Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

二：

1/首先安装数据库软件

2.设置环境变量

3.创建需要的目录

4.创建参数文件pfile

5.创建密码文件

6.数据库启动到numount，创建Oracle的建库脚本

7.创建Oracle的数据字典

1.首先安装数据库软件；安装rlwrap软件。

2.设置环境变量

export PATH

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export ORACLE_SID=willson

export PATH=$PATH:$ORACLE_HOME/bin

alias sqlplus='rlwrap sqlplus'

alias   rman='rlwrap rman'

3.创建需要的目录

mkdir -p $ORACLE_BASE/oradata/willson

mkdir -p $ORACLE_BASE/admin/willson/adump

mkdir -p $ORACLE_BASE/admin/willson/bdump

mkdir -p $ORACLE_BASE/admin/willson/pfile

4.创建参数文件

 cd cd $ORACLE_HOME/dbs

 vim initwillson.ora

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

audit_trail='db'

compatible='11.2.0.0.0'

control_files='/u01/app/oracle/oradata/willson/control01.ctl','/u01/app/oracle/oradata/willson/control02.ctl'

db_block_size=8192

db_domain=''

db_name='willson'

diagnostic_dest='/u01/app/oracle'

memory_target=442006528

open_cursors=300

processes=150

remote_login_passwordfile='EXCLUSIVE'

sessions=170

undo_tablespace='UNDOTBS1'

登陆到sqlplus / as sysdba

创建spfile

 create spfile from pfile

5.创建密码文件

 orapwd file=orapwwillson password=willson entries=10 创建密码文件

6.数据库启动到nomount，创建ORACLE的建库脚本

spool willson_dbcreate.log;

create database "willson"

character set "AL32UTF8"

national character set AL16UTF16

datafile '/u01/app/oracle/oradata/willson/system01.dbf' size 500M

SYSAUX DATAFILE '/u01/app/oracle/oradata/willson/sysaux01.dbf' SIZE 100M

UNDO TABLESPACE "UNDOTBS1"

DATAFILE '/u01/app/oracle/oradata/willson/undotbs01.dbf' SIZE 200M

DEFAULT TEMPORARY TABLESPACE temp TEMPFILE '/u01/app/oracle/oradata/willson/temp01.dbf' SIZE 300M

DEFAULT TABLESPACE uses DATAFILE '/u01/app/oracle/oradata/willson/user01.dbf' SIZE 20m

logfile GROUP 1 (

'/u01/app/oracle/oradata/willson/redo01a.rdo',

'/u01/app/oracle/oradata/willson/redo01b.rdo'

) SIZE 100M,

GROUP 2 (

'/u01/app/oracle/oradata/willson/redo02a.rdo',

'/u01/app/oracle//oradata/willson/redo02b.rdo'

) SIZE 100M,

GROUP 3 (

'/u01/app/oracle/oradata/willson/redo03a.rdo',

'/u01/app/oracle/oradata/willson/redo03b.rdo'

) SIZE 100M;

spool off

7.创建ORACLE数据字典

SQL>@?/rdbms/admin/catalog.sql

SQL>@?/rdbms/admin/catproc.sql

catalog.sql----创建数据字典基表和数据字典视图

catproc.sql----安装oracle系统包
